GS5

GS5 is the second US server in the steamlug set, it is OpenRC-based.

There are some assumptions are made in these scripts. First, /home/steam is used as the unprivileged user's home directory. Second, GNU/Screen is used to avoid an endless loop with srcds when disconnecting the underlying terminal that started the daemon. At the time of this writing, only CS:GO and Fistful of Frags dedicated servers are deployed.

Sample CS:GO daemon script

#!/sbin/runscript

depend() {
	need net
}

GAME="csgo"
GAME_LONG="Counter-Strike: GO Dedicated Server"
DAEMON="srcds_run"
DAEMON_OPTS="-game ${GAME} +game_type 0 +game_mode 0 +mapgroup mg_active +map de_dust2 -port 27015"
SHARD="csgods"
PIDFILE=/run/steam/${SHARD}.pid

start_pre() {
	checkpath -o steam -d "$(dirname $PIDFILE)"
}

start() {
	ebegin "Starting ${GAME_LONG}: ${SHARD}"
	start-stop-daemon --start --pidfile ${PIDFILE} --exec su -- steam -c \
	"cd /home/steam/${GAME}; screen -mdS ${SHARD} ./$DAEMON $DAEMON_OPTS"
	ps ax | grep -i SCREEN | grep -i ${SHARD} | awk '{print $1}' > $PIDFILE
	eend $?
}

stop() {
	ebegin "Stopping ${GAME_LONG}: ${SHARD}"
	start-stop-daemon --stop --pidfile ${PIDFILE}
	eend $?
}

The cron job that calls the update script

#!/bin/bash
update ()
{
    su - steam -c "/home/steam/update.sh ${APPID} ${GAME}"
    if [ -f /home/steam/restart_${GAME} ]; then
        #restart all services that start with the game's name and ends with ds
        find /etc/init.d/ -name "${GAME}*ds" -exec '{}' restart \;
        rm /home/steam/restart_${GAME}
    fi
}

APPID="90"
GAME="cstrike"
update

APPID="740"
GAME="csgo"
update

APPID="295230"

check script to see if the game is up to date
