This is an example of a possible Minecraft server rc.d startup script for FreeBSD.
Installation[]
- Use adduser to create a new user named minecraft. When asked to select the new user's home directory, use /srv/minecraft.
- Ensure that your /srv filesystem has enough free space (around ~100-200MB depending on your needs) - df -h will show how much space is available.
- Install Java if necessary. The port is available at /usr/ports/java/openjdk8.
- As root, run the following:
# cd /usr/ports/sysutils/screen && make install clean # cd /srv/minecraft # fetch https://s3.amazonaws.com/MinecraftDownload/launcher/minecraft_server.jar # chown minecraft:minecraft * # fetch -o /usr/local/etc/rc.d/minecraft http://vidya.dyndns.org/stuff/minecraft # chmod 0555 /usr/local/etc/rc.d/minecraft
- If you have existing server configuration files, world files, etc., copy them into /srv/minecraft and give ownership to your minecraft user.
- Edit /etc/rc.conf.local (create if it doesn't exist) and add the following line:
minecraft_enable="yes"
- The server should now start on boot. To launch, check status, and shut down, use the following commands:
# /usr/local/etc/rc.d/minecraft start # /usr/local/etc/rc.d/minecraft status # /usr/local/etc/rc.d/minecraft stop
Or:
# service minecraft start # service minecraft status # service minecraft stop
Script[]
#!/bin/sh
#
# PROVIDE: minecraft
# REQUIRE: LOGIN DAEMON NETWORKING mountcritlocal
# KEYWORD: shutdown
#
# Add the following lines to /etc/rc.conf.local to enable the minecraft server:
#
# minecraft_enable="YES"
# minecraft_user="<run server as this user>"
# minecraft_chdir="<run server in this directory>"
# minecraft_path="<path to minecraft_server.jar>"
# minecraft_flags="<set as needed>"
#
# For default setup, create a user named 'minecraft', set its home directory
# to /srv/minecraft, and place minecraft_server.jar into /srv/minecraft
#
# See minecraft_server.jar for flags
