script de démarrage init.d

Question

J'essaie de créer un script de service init.d pour le logiciel glassfish. Mais il semble que mes compréhensions dans les directives init LSB ne sont pas les meilleures.

Ce sont les commandes que le script doit faire:

/opt/glassfish/bin/asadmin start-domain /opt/glassfish/bin/asadmin stop-domain /opt/glassfish/bin/asadmin restart-domain

Mon script ressemble à ceci mais cela n'a pas fonctionné. Ceci est ma première tentative de créer un script init.d. S'il vous plaît dites-moi quand je fais quelque chose de mal.

Remarque: Veuillez regarder mon script mis à jour ci-dessous EDIT:

#!/bin/sh # ### BEGIN INIT INFO # # Provides: glassfish # Required-Start: $local_fs $remote_fs $network # Required-Stop: $local_fs $remote_fs $network # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: Glassfish scipt (Non official) # Description: Start Glassfish domain as service. # Non official startup script. # ### END INIT INFO BASE=/opt/glassfish/bin DEAMON=${BASE}/asadmin USERID=root NAME=glassfish DESC="Glassfish domain service" # PID file for the deamon PIDFILE=/var/run/glassfish.pid SCRIPTNAME=/etc/init.d/$NAME # Exit if the package is not installed [ -x "$DEAMON" ] || exit 0 # Using LSB functions to perform the operations . /lib/lsb/init-functions do_start() { start-stop-deamon --start --quiet --pidfile $PIDFILE --exec $DEAMON start-domain -- $NAME_OPTIONS } do_stop() { start-stop-deamon --stop --quiet --retry=TERM/30/KILL/5 --pidfile $PIDFILE --exec $DEAMON stop-domain } case $1 in start) if init_is_upstart; then exit 1 fi log_deamon_msg "Starting $DESC" do_start case "$?" in 0) sendsigs_omit log_end_msg 0 ;; 1) log_progress_msg "already started" log_end_msg 0 ;; *) log_end_msg 1 ;; esac ;; stop) if init_is_upstart; then exit 0 fi log_deamon_msg "Stopping $DESC" do_stop case "$?" in 0) log_end_msg 0 ;; 1) log_progress_msg "already stopped" log_end_msg 0 ;; *) log_emd_msg 1 ;; esac ;; restart|force-reload) if init_is_upstart; then exit 1 fi $0 stop $0 start ;; status) status_of_proc -p $PIDFILE $DEAMON && exit 0 || exit $? ;; *) echo "Usage: $SCRIPTNAME {start|stop|restart|status}" >&2 exit 3 ;; esac :

Lorsque je fais un '/ bin/bash -x ./glassfish status', voici le résultat:

+ case "$FANCYTTY" in + true ++ /usr/bin/tput setaf 1 + RED='' ++ /usr/bin/tput op + NORMAL='' + echo ' * is not running' * is not running + return 3 + exit 3

Mais peu importe si je commence ou arrête. Le résultat est toujours le même. Le script ne démarre pas le serveur de domaine glassfish. Sans script, tout fonctionne bien.

MODIFIER:

J'ai changé le script en ceci:

#!/bin/sh ### BEGIN INIT INFO # # Provides: glassfish # Required-Start: $local_fs $remote_fs $network # Required-Stop: $local_fs $remote_fs $network # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: Glassfish scipt (Non official) # Description: Start Glassfish domain as service. # Non official startup script # ### END INIT INFO # Using the LSB functions to perform the operations . /lib/lsb/init-functions BASE=/opt/glassfish/bin NAME=glassfish DAEMON=${BASE}/asadmin SCRIPTNAME=/etc/init.d/$NAME #PID file for the daemon PIDFILE=/var/run/glassfish.pid #If the daemon is not there, then exit [ -x "$DAEMON" ] || exit 5 do_start() { start-stop-daemon --start --quiet --pidfile $PIDFILE --exec $DAEMON start-domain } do_stop() { start-stop-daemon --stop --quiet --pidfile $PIDFILE } case $1 in start) #Check PID file if [ -e $PIDFILE ]; then status_of_proc -p $PIDFILE $DAEMON "$NAME process" && status="0" || status="$?" # IF SUCCESS dont start again if [ $status = "0" ]; then exit fi fi #Start the daemon log_daemon_msg "Starting the process" "$NAME" if do_start; then log_end_msg 0 else log_end_msg 1 fi ;; stop) # Stop the daemon if [ -e $PIDFILE ]; then status_of_proc -p $PIDFILE $DAEMON "Stopping the $NAME process" && status="0" || status="$?" if [ "$status" = 0]; then do_stop fi else log_daemon_msg "$NAME process is not running" log_end_msg 0 fi ;; restart) # Restart the daemon $0 stop && sleep 2 && $0 start ;; status) # Check status if [ -e $PIDFILE ]; then status_of_proc -p $PIDFILE $DAEMON "$NAME process" && exit 0 || exit $? else log_daemon_msg "$NAME Process is not running" log_end_msg 0 fi ;; *) # Show help echo "Usage: $SCRIPTNAME {start|stop|restart}" >&2 exit 3 ;; esac

Après le changement, la sortie est la suivante:

 * Starting the process glassfish Waiting for domain1 to start ......... Successfully started the domain : domain1 domain Location: /opt/glassfish/domains/domain1 Log File: /opt/glassfish/domains/domain1/logs/server.log Admin Port: 4848 Command start-domain executed successfully.

Il peut commencer le processus maintenant. Ensuite, le problème suivant apparaît lors de l'arrêt du service:

 * glassfish process is not running

Mais le processus est en cours d'exécution et le script n'essaie même pas d'abandonner. Il n’existe pas non plus de fichier PID glassfish sous/var/run.

Enfin je le fais travailler!

Si quelqu'un s'intéresse à la réponse. Le problème est que Glassfish n'a pas créé de fichier PID par lui-même. Il existe donc une solution de contournement nécessaire pour démarrer le programme en arrière-plan (avec &) et générer son PID.

Pour la compréhension, j'ai regardé ces messages:

Stack * (askUbuntu) -community est vraiment une grande communauté! :)

Et voici le script de travail complet:

#!/bin/sh ### BEGIN INIT INFO # # Provides: glassfish # Required-Start: $local_fs $remote_fs $network # Required-Stop: $local_fs $remote_fs $network # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: Glassfish scipt (Non official) # Description: Start Glassfish domain as service. # Non official startup script by Bernhard Sumser. # ### END INIT INFO # Using the LSB functions to perform the operations # NOT needed because no LSB functions used #. /lib/lsb/init-functions BASE=/opt/glassfish/bin NAME=glassfish DAEMON=${BASE}/asadmin SCRIPTNAME=/etc/init.d/$NAME #PID file for the daemon PIDFILE=/var/run/glassfish.pid #If the DAEMON is not there, then exit [ -x "$DAEMON" ] || exit 0 do_start() { $DAEMON start-domain & # Wait for child to exit before continuing wait # Make file with last background PID echo $! > $PIDFILE # Didn't work because the programm prints from the background. Without moving to the bg no $! can be outputed to file #(($DAEMON start-domain) & echo $! > $PIDFILE &) } do_stop() { $DAEMON stop-domain if [ -e $PIDFILE ]; then rm -f $PIDFILE fi } check_root() { if [ "$(id -u)" != "0" ]; then echo "You must be root to start, stop and restart $NAME." exit 4 fi } check_process() { # Check if the process is already running. Ignore grep line. result=`ps aux | grep /opt/glassfish/modules/glassfish.jar | grep -v grep | wc -l` } case $1 in start) check_root check_process if [ "$result" = "1" ]; then echo "$NAME is already running" else # Check if PID file exists and delete it if [ -e $PIDFILE ]; then rm -f $PIDFILE else do_start fi fi ;; stop) check_root if [ -e $PIDFILE ]; then do_stop else echo "$NAME is not running" fi ;; restart) check_root echo "Restarting $NAME..." check_process if [ "$result" = "1" ]; then do_stop echo "Starting $NAME..." do_start fi ;; status) if [ -e $PIDFILE ]; then echo "$NAME is running. PID $(cat $PIDFILE)" else echo "$NAME is not running" fi ;; *) # Show help echo "Usage: $SCRIPTNAME {start|status|stop|restart}" >&2 exit 3 ;; esac

Comme il se trouve sous /etc/init.d/, je ne suis pas sûr que le script ait encore besoin de la section INIT INFO.

Maintenant, il est possible de l'utiliser comme service normal comme ceci:

Sudo service glassfish start

Puis ajoutez-le au démarrage de rc et il démarrera après le redémarrage.

Sudo update-rc.d glassfish defaults
