Creating a Linux Service

This section describes how you can create a service to start and stop Squore using the launcher script from the installation's bin folder.

Note

The examples below assume that:

Your Squore installation is located in /opt/Squoring/squore-server
You have created a user called squore to run the service, which is optional

After creating a service, you can configure it to launch Squore at boot, or you can start and stop Squore on your system by running the following commands:

sudo service squore start
sudo service squore stop

CentOS 6.6, OpenSUSE 13.2

Create a Squore service description file in /etc/init.d/squore

#!/bin/sh
#
# Squore Server Service
#
# chkconfig: 2345 20 80

    #retval=$?
    #echo
    #[ $retval -eq 0 ] && rm -f $lockfile
    #return $retval
}

restart() {
    su $user -c "$exec restart"
}

reload() {
    restart
}

force_reload() {
    restart
}

rh_status() {
    su $user -c "$exec status"
}

case "$1" in
    start)
        $1
        ;;
    stop)
        $1
        ;;
    restart)
        $1
        ;;
    reload)
        $1
        ;;
    force-reload)
        force_reload
        ;;

        rh_status

        restart
        ;;
    *)
        echo $"Usage: $0 {start|stop|status|restart}"
        exit 2
esac
exit $?

Make the service description file executable
```
chmod a+x /etc/init.d/squore
```
Add it to chkconfig
```
chkconfig --add squore
```
instruct chkconfig to start the service at boot
```
chkconfig squore on
```
