sudo vim /etc/init.d/teamcity

Add the following contents:

#!/bin/sh
### BEGIN INIT INFO

export TEAMCITY_DATA_PATH="/opt/ts/.BuildServer"
 
case $1 in
 
start)
  start-stop-daemon --start  -c $USER --exec /opt/ts/bin/runAll.sh start
 ;;
stop)
  start-stop-daemon --start -c $USER  --exec  /opt/ts/bin/runAll.sh stop
 ;;
 esac
 
exit 0

Give it proper permissions:

    sudo chmod 755 /etc/init.d/teamcity

Add it to the startup process:

    sudo update-rc.d teamcity defaults
