How can I adapt this debian init.d script to work with CentOS 5?

  • 772

I'm trying to get an lsyncd daemon running. I installed the lsyncd RPM from epel, but it doesn't seem to come with an init.d script. In the lsyncd repository, there's this script that works with Debian. However, when I try to run this under CentOS, I get this message:

/etc/init.d/lsyncd: line 46: log_daemon_msg: command not found

How can I adapt this to work with CentOS?

centos debian init.d centos5

  1. writing from scratch could be easier, depending on how complex the script is. the issue you're running into is this line in the script:

    . /lib/lsb/init-functions

    which loads all the functions for debian's startup scripts. in that is a function 'log_daemon_msg' which is where your problem is at.

    you could look at the init-functions file to figure out what log_daemon_msg does, and replicate on CentOS, or you could step through the Debian script and see what is actually run (probably less than 5 lines of commands)

  2. /usr/share/doc/initscripts-*/sysvinitfiles contains a template you can use as a model for modifying the existing script or creating a new one.

  3. I had the same issue. Here is what I conjured up following the other recommendations, init.d tutorials, and the existing debian script found on the lsyncd googlecode site link text. Hope this helps others, just copy and paste!

# description: Lsyncd uses rsync to synchronize local directories with a remote \
#    machine running rsyncd. It watches multiple directories trees \
#    through inotify. The first step after adding the watches is to \
#    rsync all directories with the remote host, and then sync single \
#    file by collecting the inotify events. So lsyncd is a light-weight \
#    live mirror solution.
# pidfile: /var/run/lsyncd.pid
# processname: lsyncd

# Source function library.
. /etc/init.d/functions

PIDFILE="/var/run/lsyncd.pid"
LSYNCD_DIR="/usr/local/bin/"

start() {
        echo -n "Starting Live Syncing Daemon: "
        if [ -f $PIDFILE ]; then
                PID=`cat $PIDFILE`
                echo lsyncd already running: $PID
                exit 1;
        else
                cd $LSYNCD_DIR
                daemon ./lsyncd $OPTIONS
                RETVAL=$?
                echo
                [ $RETVAL -eq 0 ] && touch /var/lock/subsys/lsyncd
                return $RETVAL
        fi

}

stop() {
        echo -n "Shutting down Live Syncing Daemon: "
        echo
        killproc lsyncd
        echo
        rm -f /var/lock/subsys/lsyncd
        return 0
}

case "$1" in
    start)
        start
        ;;
    stop)
        stop
        ;;
    status)
        status lsyncd
        ;;
    restart)
        stop
        start
        ;;
    *)
        echo "Usage:  {start|stop|status|restart}"
        exit 1
        ;;
esac
exit $?

    Paste that code into /etc/init.d/lsyncd.

    Change file permissions:

    chmod 755 /etc/init.d/lsyncd

    In your /etc/lsyncd.conf.xml file you need to uncomment the "<pidfile .../>" node and set its filename attribute to "/var/run/lsyncd.pid".

    Then you should be set to start the service!

    /sbin/service lsyncd start

    Cheers, Randy
