警告
因为这是Wiki的一个条目,可以在任何时间内被任何人编辑,因此建议你不要完全使用这个脚本,而是将其当作编写脚本的指导手册看待。
这是一个简单的 Ubuntu 服务器启动脚本,它没有控制台,因为这不是问题。因为游戏内已经有一个控制台。该脚本不会更新 Minecraft,但在晚些时候会加入这个功能。
先决条件
- set up a user and group for minecraft so that it doesn't run as root
sudo adduser --system --no-create-home --home /srv/minecraft-server minecraft sudo addgroup --system minecraft sudo adduser minecraft minecraft # this adds user "minecraft" the group "minecraft"
- hand your server-installation over to our new user, I have mine in /srv/minecraft-server
sudo chown -R minecraft.minecraft /srv/minecraft-server
- create and edit the start/stop script creating a new file under /etc/init/minecraft-server (NOT /etc/init.d but /etc/init (without the .d) )
sudo nano /etc/init/minecraft-server
and pasting the following into it. Don't forget to change the directory after "chdir" to your installation
# description "start and stop the minecraft-server" start on runlevel [2345] stop on runlevel [^2345] console log chdir YOUR_INSTALLATION_DIRECTORY setuid minecraft setgid minecraft respawn respawn limit 20 5 exec /usr/bin/java -Xms1536M -Xmx2048M -jar minecraft_server.jar nogui
Above Explained (Note, this script isn't usable.):
# description "start and stop the minecraft-server" <-- Adds a tip to what this script does. start on runlevel [2345] <-- Tells Ubuntu when to start the server. Runlevels 2, 3, 4, and 5 are the "normal operation". stop on runlevel [^2345] <-- Tells Ubuntu when to stop the server. The ^ means NOT. console log <-- Logs the actions taken chdir YOUR_INSTALLATION_DIRECTORY <-- Changes the active directory to the installation dir. setuid minecraft <-- Sets the UserID to "minecraft" (acts like Minecraft user) setgid minecraft <-- Sets the GroupID to "minecraft" (acts like Minecraft group) respawn <-- Allows the program to "respawn" (restart) when it dies unexpectedly. respawn limit 20 5 <-- Allows the program to "respawn" 20 times in 5 seconds. exec /usr/bin/java -Xms1536M -Xmx2048M -jar minecraft_server.jar nogui <-- Below... 'exec' > Executes command '/usr/bin/java' > Invokes Java. '-Xms1536M' > Sets minimum allocated memory limit. '-Xmx2048M' > Sets MAXIMUM allowable memory limit. '-jar minecraft-server.jar' > Tells Java to run the jarfile minecraft_server.jar 'nogui' > Tells minecraft-server.jar to run without a GUI. (Graphical screen).
- Now install the start/stop to the default runlevels by running
sudo initctl reload-configuration
If you get an error saying the file does not exsist, try moving the minecraft-server file to /etc/init.d/ Also if after running sudo start minecraft-server says that they is no job for it, try running "sudo /etc/init.d/minecraft-server start"
Usage
- to start the server
sudo start minecraft-server
- to stop the server
sudo stop minecraft-server
Troubles?
You can check the server log by using:
sudo tail /var/log/upstart/minecraft-server.log
