restart apache every 12 hours using linux service and python file
Question: Hi i want to use this for restart apache service every 12 hours and i put the
file `apache_rest` in `/etc/init.d/apache_rest` i run but get some error :

    
    
    [root@localhost init.d]# service apache_rest start
    Starting server
    /etc/init.d/apache_rest: line 13: /sbin/start-stop-daemon: No such file or directory
    

apache_rest file:

    
    
    #!/bin/bash
    WORK_DIR="/var/lib/foo"
    DAEMON="/usr/bin/python"
    ARGS="/home/lol/apache.py"
    PIDFILE="/var/run/foo.pid"
    USER="foo"
    case "$1" in
      start)
        echo "Starting server"
        mkdir -p "$WORK_DIR"
        /sbin/start-stop-daemon --start --pidfile $PIDFILE \
            --user $USER --group $USER \
            -b --make-pidfile \
            --chuid $USER \
            --exec $DAEMON $ARGS
        ;;
      stop)
        echo "Stopping server"
        /sbin/start-stop-daemon --stop --pidfile $PIDFILE --verbose
        ;;
      *)
        echo "Usage: /etc/init.d/$USER {start|stop}"
        exit 1
        ;;
    esac
    exit 0
    

and the python file :

    
    
    #!/usr/bin/python
    import os,signal,time,multiprocessing
    stop_event = multiprocessing.Event()
    def stop(signum, frame):
        stop_event.set()
    signal.signal(signal.SIGTERM, stop)
    if __name__ == '__main__':
        while not stop_event.is_set():
            os.system('service httpd restart')
            time.sleep(43200)
    

thanks ^_^


Answer: Simply add this line to root's crontab:

    
    
    0 1,13 * * * /etc/init.d/httpd restart
    

You don't need such a convoluted solution.
