How-To : Autostart Parsoid on openSUSE 13.1
Once Parsoid is installed on openSUSE it might be handy to have is started automatically once system is restarted.
First we have to create startup script.
/etc/init.d/parsoid
#!/bin/sh
#
# description: Node.js /srv/parsoid/api/server.js
#
. /etc/rc.status
USER="root"
DAEMON="/usr/bin/node"
ROOT_DIR="/srv/parsoid/api"
LOG_ROOT="/var/log/nodejs"
SERVER="$ROOT_DIR/server.js"
LOG_FILE="$LOG_ROOT/parsoid.log"
LOCK_FILE="/var/lock/subsys/node-server"
WORKERS_NUMBER=8
do_start()
{
if [ ! -f "$LOCK_FILE" ] ; then
echo -n $"Starting $SERVER: "
runuser -l "$USER" -c "$DAEMON $SERVER -n $WORKERS_NUMBER >> $LOG_FILE &" && echo || echo
RETVAL=$?
echo
[ $RETVAL -eq 0 ] && touch $LOCK_FILE
else
echo "$SERVER is locked."
RETVAL=1
fi
}
do_stop()
{
echo -n $"Stopping $SERVER: "
pid=`ps -aefw | grep "$DAEMON $SERVER" | grep -v " grep " | awk '{print $2}'`
kill -9 $pid > /dev/null 2>&1 && echo || echo
RETVAL=$?
echo
[ $RETVAL -eq 0 ] && rm -f $LOCK_FILE
}
case "$1" in
start)
do_start
;;
stop)
do_stop
;;
restart)
do_stop
do_start
;;
*)
echo "Usage: $0 {start|stop|restart}"
RETVAL=1
esac
exit $RETVAL
Remember to adjust all paths and number of worker processes accordingly to your installation.
Once startup script is in place we have to enable Parsoid to be automatically started:
chkconfig parsoid on
From now on Parsoid will be automatically started after each restart.
