Linux :transformer en service

Cela dépend de votre gestionnaire de système

la façon la plus courante de le faire sur debian/ubuntu est de construire un initscript et de le placer dans /etc/init.d ou /etc/rc/init.d et placez un script nommé mytestprogram dans ça.

ceci est un exemple d'initscript :

#!/bin/sh
### BEGIN INIT INFO
# Provides:          testone
# Required-Start:    $local_fs
# Required-Stop:     $local_fs
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# X-Interactive:     false
# Short-Description: Example init script
# Description:       Start/stop an example script
### END INIT INFO

DESC="test script"
NAME=testone
#DAEMON=

do_start()
{
   echo "starting!";
}

do_stop()
{
   echo "stopping!"
}


case "$1" in
   start)
     do_start
     ;;
   stop)
     do_stop
     ;;
esac

exit 0

Je vous propose de regarder quelques scripts dans ce répertoire, c'est simple si vous connaissez un peu bash;)

Voici un exemple de script shell (assurez-vous de remplacer le nom MAT par le nom de votre application) :

Je crée un GitHubGist avec la dernière version de mon script et une brève explication pour aider ceux qui en ont besoin. Lien GitHub Gist

#!/bin/bash
