Hey Listees,
I have a question (hopefully quite simple) about the system V init scripts in /etc/init.d. I have an app installed and for some reason it had no system V init script. It has been installed a long while now so I can't quite remember whats going on but basically I remember I wrote the init script my self and the app is enabled as a service which chkconfig to run at system levels 3, 4 and 5. However when I wrote the script I only ever added a "start" and "stop" clause to it (why I can't remember?), now I need to add a "restart" clause but I'm having an issue.
I have pasted the code below from my "restart" clause but from what I can tell, it is killing the app but not restarting it, I think because the killing process is still in action so when it start the app again it just gets killed straight away. If I enter "/etc/init.d/my_app restart" the app is terminated but does not start again, entering "/etc/init.d/my_app start" immediately after fires it up straight away so there is no problem there; can someone suggest a better way as my scripting is very begginnerish (if thats a word) and I don't doubt for a second I am doing this in a very inefficient manner:
<snipety snip snip>
restart) echo -n "Stopping my_app: " pgrep my_app | while read PIDS; do # I have chosen this method because my_app spawns various child processes kill -9 $PIDS # and they all need to DIE! (Killing the parent process would kill the child processes done # however there are actually two parent processes so this seems like a good idea?) echo -n "Starting my_app: " /usr/local/my_app/sbin/my_app_bin & exit $? ;;
<snip snap snorum>
Any input is greatly appreciated!
Regards, James ;)
