Pre-requisites Edit

  1. Motivations: there are already a lot of servers. Why do you want to add another one?
  2. Differentiation: what differences will your server brings to players? What do you offer?
  3. Responsibility: players will probably invest a lot of time and efforts playing and building on your server. If you resign after a few weeks/months, you'll waste those. Be sure you can commit enough time on a long enough period. Plan your exit (succession plan, files availability for download, schematics of the builds, etc.)
  4. Time: even if you're knowledgeable enough to automate some of the work, you'll need to devote time to administration and technical matters. And it won't be playing time...
  5. Money: apart from your time, hosting will cost you real money, even if you do it at home. Make a budget estimate...
  6. Technical knowledge: just like with a Web server, almost everyone can start a Minecraft server. But to do it properly, fix issues, provide decent performance and avoid being hacked, you'll need some technical knowledge (operating system & network, security, scripting, a bit of Java)
  7. Adequate hardware and network bandwidth: if you don't want your players to complain too much about lags (they will anyway!), be sure to have a strong enough computer, with a very good connection to the Internet (this rules out most home installations... Plus you don't want to set your home on fire, don't you?).

Hosting Edit

There are a lot of Minecraft hosters out there. If you use their services, they might provide a more or less advanced server installation as part of their commercial offering.

For what follows, we will assume that you perform your own installation on a computer that you own or rent, whether a dedicated one or a virtual private server.

Home hosting Edit

Well, if you haven't been scared by our previous warnings about home hosting, or just want to make a small scale test, here are some networking issues to ponder (warning: that will be more complicated!).

Will you have enough network bandwidth?

With the ADSL connections that many people are using nowadays, you download quickly, but upload more slowly. Bad luck, because for a server you just want the opposite. You receive few data and send many. This will quickly become a bottleneck to your server performance...

Does your home have a static public IP address or a dynamic one?

Having a static one is best, as you'll just need to declare in your Internet device's administration interface that you want to forward network packets it receives to a computer on your internal network with a static internal IP or constant MAC address (that's Network Address Translation - NAT), whether using the same network port or not (this last case being Port Address Translation - PAT).

If your home has a dynamic public IP address, it will get even more complicated. You'll have to provide your users with an internet name instead of an IP address, and find some way to change the IP address it redirects to, every time your home IP address changes. You can do that, for example, with services like DynDNS.

Professional hosting Edit

Compared with Minecraft hosters, you would have to handle every technical aspects of your server, but be rewarded with complete freedom, advanced scripting (notably to interact with the LOTR mod), ability to install complementary software (web server, forum, blog, pictures gallery, etc.) and possibility to diagnose most problems (possibly through additional tools).

And it's not necessarily more expensive than Minecraft hosters, especially if you want configurations with lots or memory, quick SSD disks, guaranteed bandwidth, etc.

You'll find many companies offering dedicated servers, virtual private servers or cloud based servers (in decreasing order of price and interest).

Unix instructions Edit

You can use any variant of Linux or BSD Unix-like 64-bit operating systems.

But for a server usage, it's preferable to use them only for this purpose and "headless" (without Graphical User Interface). Else the Windows/MAC comments in the last section apply just the same...

As a rule of thumb, aim for a "Juice" (Just enough Operating System - JeOS) approach: only install and allow to run things (packages & processes) that are expressly required for the usage you want. The BSD operating systems are perfect for that, as they come with no packages installed in the initial setup and lean running processes. The author of this page peculiarly recommends the FreeBSD operating system, which he has been using as a hosting platform since 1996. It's reliable, powerful and secure.

Installation, configuration, optimisation and security hardening of operating systems are beyond the scope of this Wiki page (see the technical knowledge pre-requisite above).

.

Software pre-requisites Edit

As Minecraft, Forge and Bukkit are Java applications rather than operating systems & architecture dependent binary applications, you'll need a special software to run them: a Java Runtime Environment (JRE).

The use of the version included in OpenJDK is recommended. Check your package management system for instructions on how to install it on your favourite OS.

For example, on the FreeBSD OS, you just need to enter the following command (as super user - root):

root# pkg install java/openjdk8-jre

Also, be sure to regularly update your JRE to the last available version, as there are frequent security issues with old Java versions...

.

Forge LOTR server Edit

Installing the server Edit

  1. Create a "minecraft" user and group on the operating system (not a Mojang account!). You'll use this ID to run your Minecraft server and own most of its game related files. In case of security issue (Minecraft 1.7.10 is known to have many security holes), you won't make it too easy for an attacker to achieve a direct and complete takeover of your server...
  2. Create a directory to put all your server files, usually under the user filesystem (which allows for special mounting options for more security). If you have SSD drives, be sure to use them as a first choice as they are way quicker than classical hard drives. You'll probably need around 50 to 150 GB of available disk space (after 6 months and 450 different players, my own server used around 70 GB). And more if you want to keep online backups.
  3. Download the Recommended Forge version for Minecraft 1.7.10 (use a command line HTTP client such as "fetch", "curl" or "wget". Or transfer it from another machine). Avoid the Latest Forge versions as there are sometimes regressions in them, unless you want a fix very badly (check the Forge changelog). You'll find the download link under the "Installer" icon, after skipping the ad screen.
  4. Install Forge (see the command line below). You can delete the installer after that.
  5. Make some startup scripts. The examples provided below are simple ones. More interesting settings are possible with additional software such as GNU Screen to keep the ability to pass commands to the Minecraft server console from the operating system command line (check the Forge + Bukkit LOTR server below for examples). It's also usual to provide an automatic start/stop script, but these are dependent upon the OS you use (there are multiple examples on the Minecraft wiki under Server setup). Notice the minimum and maximum amount of memory allowed to the server (in bold). You need, of course, to adapt these figures to your hardware characteristics... Remember that this memory is only the one used by the server, not for the server code itself or the Java runtime environment. If you use the top command, check the "SIZE" column to know the sum of the three, and the "mem" line to see if it can fit in what's available, without using swap space.
  6. Launch your startup script for the first time. It will immediately fail because Mojang wants you to agree to their EULA (End User Licence Agreement) first. Among the noticeable things, a blank server.properties configuration file and an empty mods directory are created...
  7. Agree to the Mojang EULA by changing the eula=false line in eula.txt to eula=true
  8. Download and install the LOTR mod in the mods directory. If you can't find the download URL on MediaFire (not so easy!), transfer the file from another machine.
  9. Launch the startup script for the second time. It will immediately return you to the command line prompt as your server is running "in the background". It will also create all the missing configuration files. Wait till you see a line saying "Successfully replaced LOTR world info in MiddleEarth" at the end of the nohup.out file, then stop the server.
  10. Configure the server (see next section)

.

For example, on the FreeBSD system, this translates to the following commands (each one on a single line, without the root# prefix):

root# pw groupadd minecraft
root# pw useradd minecraft -w no -d /home/minecraft -g minecraft -c "Minecraft server owner"
root# mkdir /home/minecraft
root# cd /home/minecraft
root# fetch http://files.minecraftforge.net/maven/net/minecraftforge/forge/1.7.10-10.13.4.1448-1.7.10/forge-1.7.10-10.13.4.1448-1.7.10-installer.jar
root# java -jar forge-1.7.10-10.13.4.1448-1.7.10-installer.jar --installServer
root# rm forge-1.7.10-10.13.4.1448-1.7.10-installer*
root# echo 'su -m minecraft -c "./forge.sh"' > start.sh
root# echo 'nohup java -Xms2G -Xmx8G -jar forge.jar nogui &' > forge.sh
root# echo 'kill -15 `ps -ax | grep forge.jar | grep -v grep | sed "s/ .*//"`' > stop.sh
root# ln forge-1.7.10-10.13.4.1448-1.7.10-universal.jar forge.jar
root# chmod a+x *.sh
root# chown -R minecraft:minecraft /home/minecraft
root# ./start.sh
root# sed "s/eula=false/eula=true/" eula.txt > $$.tmp ; mv $$.tmp eula.txt
root# cd mods
root# fetch http://download2074.mediafire.com/dow6uwny9bkg/55hi865d4e83b5h/%5B1.7.10%5D+The+Lord+of+the+Rings+Mod+B24.4.jar -o The_Lord_of_the_Rings_Mod_B24.4.jar
root# cd ..
root# ./start.sh
root# sleep 20 ; tail nohup.out
root# ./stop.sh

.

Configuring the server Edit

All the files under the config directory are generally OK for everyone's use, the only possible exception being the LOTR mod configuration file that some of you may want to tweak (you will at least want to review it).

What really needs editing is the Minecraft configuration file: server.properties

Please use the Minecraft wiki link above to set generic gameplay options (or this old one for 1.7.x Minecraft versions).

The technical things relevant for a server are:

Comments
motd A Minecraft Server Your server name or description. If you use additional mods, it would be a good idea to mention them here. You can use color or formatting codes if you want to do something fancy
server-ip (blank) In most cases, you can leave this blank and your Minecraft server will "listen" on every IP address your server has. If you have several public IP addresses and want to use only one, specify it here
server-port 25565 Using this default value will remove the need for players to explicitely specify your server network port. Change this only if you host several Minecraft servers on your computer and do not have enough public IP addresses for each, each server would then need his own port
query-port 25565 Same principle. Try to use the same value than for server-port. You might want to declare these ports in your /etc/services files for easier reference:

minecraft       25565/tcp  #Minecraft server minecraft       25565/udp  #Minecraft server

enable-query false true Change this if you want to enable external web sites to obtain information about your running server (software and plugins used, number and identity of players connected, max players, etc.). This is sometimes useful for your server promotion
snooper-enabled true false On the contrary, change this to disable sending information about your server to Mojang, which won't help you anyway with a modded installation
max-players 20 Apart from boasting with your server operators colleagues, the main use of this server parameter is to prevent your server from crashing when out of memory with too many players connected. On vanilla Minecraft, you can roughly count 7-15 players per GB of RAM. With the LOTR mod memory greediness, you can probably count 5-10 players per GB
white-list false For production use, you'll probably keep this set to false for an open to all server. However, during your initial world setup, you might want to set this to true (and add yourself to the white or op list file) to be able to work undisturbed

The last thing you might want to do before restarting your server, would be to provide a server icon (displayed in the server list of player's Minecraft clients). To do so, just put a PNG file (typically of 64x64 pixels size) named server-icon.png in your server directory.

.

Adding other mods Edit

Client mods Edit

With all the good mods available, you might be tempted to add things beyond the LOTR mod. Keep in mind that players lacking any of your client mods won't be able to connect to your server! Also keep in mind that many players (quite often those using mod packs) don't have the knowledge to add additional mods to their Minecraft client. So this decision could have an impact on your potential number of users.

That said, you usually just have to add the JAR file of these other mods to your mods subdirectory, launch your server once to let them create their configuration file, exit, review or modify their configuration file, then restart your server and verify in the logs/fml-server-latest.log file that everything went well.

The LOTR mod is a huge modification of Minecraft. Be extra careful when adding other big mods as there will surely be side effects or even head start crashes... To stay on the safe side, check the Compatibility with other mods wiki page first!

.

Server only mods Edit

Apart from the FastCraft optimization mod, than most people here know about, and which is both a client-only and server-only mod, there are only a handful of server only mods that you can use on your 1.7.10 servers (also check here).

Among these, we can mention:

  • ForgeEssentials : apparently aims to be a Forge core-functions replacement for popular Bukkit plugins such as Essentials, PermissionsEx, WorldGuard, and others.
  • ServerTools : A lighter alternative offering login message, nicknames, muting players, player's inventory opening, memory and TPS reports, permissions & groups, chat prefixes, teleportation including across dimensions...
  • My Town 2 : protection against some forms of griefing.
  • Tick Dynamic : some much needed performance optimizations when you don't have Spigot.
  • World Edit : a Forge version of the famous plugin that you'll certainly need for world setup and builds import using schematics files.
  • Mod Control - A server-side mod that prevents players from joining if they have certain mods installed. The config to prevent players from joining if they're using CheatingEssentials (a common cheating mod) is here.
  • Joetater - A mod made by Mevans himself that allows you to save region files. Especially useful when you want to regenerate a world, but keep existing major builds safe.

Forge + Bukkit LOTR server Edit

Introduction to a complicated story Edit

Bukkit is a widely sprayed, alternative way to extend Minecraft, beside Forge. Bukkit extensions are called plugins and run only on the server side, thus allowing players to use a vanilla Minecraft client. Compared with mods, they also tend to get along between themselves a lot better. There are more than 15 000 plugins available and the majority of Minecraft servers are using them.

If Bukkit is an alternative to Forge and the LOTR mod a Forge extension, how can we combine the two?

The answer is to use a special software called Cauldron (formerly MCPC+). Cauldron is a combination of Minecraft Forge and the Spigot project to allow you to run a Forge server with plugins installed. While Spigot is a high performance Minecraft server, which in itself makes another excellent reason to consider it! (see the article Improving your Minecraft server’s performance for some examples of Spigot optimizations).

Just when you thought you reached the Nirvana of Minecraft gaming, it happens that the legal status of Bukkit and derivatives, including Spigot and Cauldron, is currently in turmoil, which has caused the end of their updates and downloads.

Fortunately, a Russian developer called Prototik has stepped in, and offers a Forge up-to-date alternative named KCauldron (available for download on his repository or on the excellent Yive's Mirror).

The last issue is that Mevans, the LOTR mod author, does not recommend using Cauldron to run his software, as you can read in the FAQ.

However, so far, the LOTR mod does indeed work near perfectly under (K)Cauldron, this unsupported combination being used in almost all the existing LOTR modded servers (with the notable exception of the official one).

.

Software pre-requisites Edit

For some reason, the classical syntax to launch a process in the "background" and detach it from the terminal ("nohup command &") won't work with Bukkit and derivatives such as (K)Cauldron.

In order to launch the Minecraft server and then disconnect from the computer, we will have to install an additional software called terminal multiplexer, the best known ones being GNU Screen and Tmux.

Again, check your package management system for instructions on how to install them on your favourite OS.

For FreeBSD, you would just need to enter the following command (change screen by tmux, if you want that one):

root# pkg install sysutils/screen

These commands (also usable with Forge servers) bring an additional benefit: the ability to communicate with the Minecraft console from the command line (to enter Minecraft commands or talk in the chat).

On a more trivial side, you'll also need to install an Unzip package to uncompress the KCauldron distribution:

root# pkg install archivers/unzip

.

Installing the server Edit

  1. Create a "minecraft" user and group (same as above).
  2. Create a directory to put all your server files (same as above).
  3. Download the latest KCauldron version for the Recommended Forge version for Minecraft 1.7.10 (use a command line HTTP client such as "fetch", "curl" or "wget". Or transfer it from another machine).
  4. Install KCauldron (see the commands lines below).
  5. Make some startup scripts. The examples provided below use the GNU Screen utility. 
  6. Launch your startup script for the first time, It will immediately return you to the command line prompt as your server is running "in the background". It will also create all the missing configuration files and an empty mods directory. Wait till you see a line saying "Done (x.yyys)! For help, type "help" or "?"" at the end of the logs/latest.log file, then stop the server.
  7. Download and install the LOTR mod in the mods directory (same as above).
  8. Launch the startup script for the second time (same as above).
  9. Agree to the Mojang EULA (End User Licence Agreement) by creating a eula.txt file with eula=true (for compliance with Mojang requirements and good karma).
  10. Configure the server (see next section).

.

For example, on the FreeBSD system, this translates to the following commands (each one on a single line, without the root# prefix):

root# pw groupadd minecraft
root# pw useradd minecraft -w no -d /home/minecraft -g minecraft -c "Minecraft server owner"
root# mkdir /home/minecraft
root# cd /home/minecraft
root# fetch http://tcpr.ca/files/kcauldron/KCauldron-1.7.10-1481.148.zip
root# unzip KCauldron-1.7.10-1481.148.zip
root# rm KCauldron-1.7.10-1481.148.zip
root# ln KCauldron-1.7.10-1481.148-server.jar kcauldron.jar
root# mkdir setuid
root# echo 'su -m minecraft -c "setuid/start.sh"' > start.sh

root# cat > eula.txt << EOF

EOF
.

Some comments about these command lines:

  • The GNU Screen utility is touchy about the user ID. Between the first and subsequent commands used on a screen, it has to be the same UID.
  • Minecraft takes into account the languages environment variables. For example, if we use values suitable for French at server launch, the error messages displayed in game would be in that language too. That's why we unset them before launching the server.
  • We could have used a stop command similar to the one provided for Forge (just replacing forge.jar by kcauldron.jar), but now that we can "talk" to the Minecraft console it was more interesting to use the save-all and stop commands (the result is the same).
  • The say command is just an example to communicate with the Minecraft players from the Unix command line. The messages sent as parameters will be prefixed in the chat with a "[Server]" mention.
  • You can create additional commands but notice you don't have to use the slash prefix for them.

.

Configuring the server Edit

All the things described in the Forge server configuration section apply just the same for (K)Cauldron.

But there are new configuration files to check: bukkit.yml, spigot.yml, cauldron.yml and kcauldron.yml.

The remaining ones, commands.yml, help.yml, permissions.yml and tileentities.yml, are either OK or superseded by very common plugins that you will certainly use, such as Essentials or PermissionsEx, so you don't have to mind about them for the moment.

Here are the settings that you should consider:

File / Section /

Configuration item

Default

value

New

value

Comments
bukkit.yml / settings /

allow-end

true false In a non vanilla multi-player setting, it's best to forbid players to enter the End dimension and... end the game!
bukkit.yml / settings / query-plugins true false Unless you set enable-query=true in server.properties and have attractive plugins that you think could help promote your server on web sites such as minecraft-mp, you should set this to false to prevent disclosure of your plugins list, especially if you installed anti-cheating plugins that you want to keep secret.
spigot.yml / settings / restart-script ./start.sh setuid/start.sh If you use the auto-restart feature, there's no need to use the su script in ./start.sh as the server already runs under the minecraft account
spigot.yml / world-settings / default / anti-xray / engine-mode 1 2 If you have a powerful enough computer, switch to engine-mode=2 for an Orebfuscator plugin behavior. Beside that, replacing valuable ores by stone in a biome such as Mordor won't really hide them!
spigot.yml / world-settings / default / anti-xray / hide-blocks (many) (even more) Here are some additional suggestions, with forgotten vanilla Minecraft blocks and LOTR ores:

52 (minecraft:mob_spawner), 89 (minecraft:glowstone), 90 (minecraft:portal), 119 (minecraft:end_portal), 120 (minecraft:end_portal_frame), 153 (minecraft:quartz_ore), 166 (lotr:oreCopper), 167 (lotr:oreTin), 168 (lotr:oreSilver), 169 (lotr:oreMithril), 190 (lotr:oreNaurite), 191 (lotr:oreMorgulIron), 209 (lotr:mobSpawner), 218 (lotr:oreQuendite), 220 (lotr:spawnerChest), 221 (lotr:quenditeGrass), 226 (lotr:elvenPortal), 231 (lotr:oreGlowstone), 412 (lotr:oreGulduril), 423 (lotr:morgulPortal), 455 (lotr:oreSulfur), 456 (lotr:oreSaltpeter), 511 (lotr:utumnoPortal), 537 (lotr:utumnoReturnPortal), 538 (lotr:utumnoReturnLight), 539 (lotr:utumnoReturnPortalBase)

spigot.yml / world-settings / default / anti-xray / replace-blocks - 1

- 5

- 1

- 3

- 12

- 13

- 165

- 535

- 536

For anti-xray engine mode 2, all the following blocks (minus block ID 5, minecraft:planks, which was apparently an error) will be replaced with the hide blocks enumerated above.

1 (minecraft:stone), 3 (minecraft:dirt), 12 (minecraft:sand), 13 (minecraft:gravel), 165 (lotr:tile.lotr:rock), 535 (lotr:tile.lotr:mordorDirt), 536 (lotr:tile.lotr:mordorGravel)

cauldron.yml / logging / user-login false true You'll often have players complaining about not being able to login. Setting this to true will enable debug traces of their login process
cauldron.yml / world-settings / max-players-visible - 1 some number (40 or 60?) If you have set the maximum number of players to a high number (> 100), this will be useful to limit the number of players displayed using the tab command
kcauldron.yml / updatechecker / enable true false Without being too paranoid, it's generally not a good idea to have your server initiate connections to outside servers. It's better to do it yourself...

.

Adding other mods Edit

It's the same as with Forge for client mods.

For server only mods, you won't need them as you'll find a plugin offer which is both richest and better established.

The only one you could possibly want is FastCraft, which is now reported to work on the server side with recent versions of KCauldron (> 1.7.10-1448.121).

.

Installing and configuring plugins Edit

The first question is "which ones?", as they are so many ot them!

You could start by checking this popular selection of plugins, and then review the Most downloaded Top Minecraft Bukkit plugins list.

To give you some ideas, here are the results of a survey made in January 2015 about the plugins used by LOTR servers, and a post about some plugins this page author is using for his own LOTR server.

You can use almost all plugins versions made for CraftBukkit up to 1.7.9 (check the "Files" tab / "Game version" column on dev.bukkit.org), but usually not those made for CraftBukkit 1.8+ (of course !). Most Spigot plugins work too.

The plugins installation itself is quite similar to the procedure used for mods: you usually just have to add their JAR file to your plugins subdirectory, launch your server once to let them create their configuration file, exit, review or modify their configuration file, then restart your server and verify in the logs/fml-server-latest.log file that everything went well.

Check the Configuring third-party software for the mod page for hints on how to best use them with the mod.

.

A recommended selection of server administration plugins Edit
  • Essentials : Lots of commands and configuration options to control most administration needs.
  • PermissionsEx : THE permission manager system. Control who/which group will have access to any part of a plugin
  • WorldEdit : THE world editing plugin, with import / export of builds in schematic file format. Stay at version 5.6.3 as versions above 6.x don't work for Minecraft 1.7.10
  • NoCheatPlus : A good anti cheating plugin, although it needs to be told about the LOTR blocks in its configuration file for full awesomeness
  • OpenInv : Manipulate player's inventories, both online and offline. Sooner or later you'll have to use it to settle conflicts between players...

.

Some plugins suggestions for extending the LOTR gameplay Edit
  • Advanced Item Effects : Want a gold ring with invisibility effect when worn? This plugin can do it! And many other things...
  • Item Namer : Want to name this magical gold ring "The One Ring", and attach lore to it? Stop here.
  • RecipeManager 2 : Enchantments disappeared from Middle Earth with the removal of diamonds. If you want to reintroduce them with another recipe, check this plugin. Needs configuration to display the recipes of LOTR items.
  • mcMMO : This plugin adds skills you can train and level in, just like in many RPG.
  • Citizens : This plugins adds NPCs that talk and act as active Denizens, Sentries, Traders, Builders and more.
  • Factions : Extends the LOTR factions into territories the Kings (all players want to be Kings!) can fight over.

.

Common tasks Edit

Server staff Edit

You'll need to define and configure the role and "powers" of Owners, Admins and Moderators.

Be careful about your server casting. If you disagree later on, think about how you will share things and part peacefully.

It might get complicated when there are several people who are paying for the server, or with file access to the server files folder (sensitive information such as the worlds seeds might be leaked)...

.

Making rules Edit

You'll also need to define what's allowed or disallowed on the server. Check the servers pages for examples of that or the Minecraft wiki page on Griefing, for an extensive list of the bad things that could (will!) happen.

.

World setup Edit

Before opening your server and advertising it, you might want to build or import one or more spawn points for your players, and add some major builds. This is of course beyond the score of this wiki page.

Windows/MAC comments Edit

Operating Systems choices have almost the same potential for bickering as religious matters...

These operating systems are not recommended (by this page author) as they devote a lot of your preciousss server resources to the interaction with the console user, need a lot of administration on their own (well at least for Windows) and their complexity creates additional security issues (remember your server will be on the Internet? You certainly don't want to serve as a relay to attack others or provide wide access to your home computers!).

On the other hand, as Mac OS X and FreeBSD are closely related, especially at the "user land" utilities level (with the notable exception of the packaging system), the command lines provided here should be relatively close to work out of the box on a modern Mac.

Java memory management tuning Edit

As you have seen, we have used so far very limited Java memory management options (-Xms2G -Xmx8G).

But there are far more options available (beware, they often vary between Java versions).

If you encounter issues such as periodic lags while you have excellent TPS and memory available, this might be caused by an application "pause" for memory garbage collection.

You might then want to use an alternative Java garbage collector, tuned for low latency.

The problem here is that there is no one size fits all solution. The options to use will depend greatly upon the quantity of RAM you want to allocate, the number of processors/cores, etc.

You even risk lowering performance or causing memory outages because "quicker" garbage collector algorithms may lead to an increase in memory fragmentation, which itself might lead to out of memory errors (the global quantity of memory available to the application could be OK, but in chunk sizes all inferior to the quantity requested).

The normal way of doing things would be to read the contents of the previous links, put measurements in place, try different options for some time, and then retain the best one.

That said, if you think all of this is overly complicated (and it is!), you might just try to add "-XX:+UseConcMarkSweepGC" (the usual best bet) to your Java options and see if it's better...

We can also note that one of the other two default Java settings used in Minecraft clients is deprecated in Java 8 and should be removed if you use it:

  •     -XX:+CMSIncrementalMode : This option was deprecated in JDK 8 with no replacement, along with other options that start with CMSIncremental.

Control panels Edit

There are many additional softwares that aim to simplify the installation and administration of Minecraft servers.

If you have followed us so far, they won't be of much use to you now (and they may be themselves complicated to install), but you might still want them for reports and monitoring.
