Hello, For the moment I'm setting up a configuration with apache as loadbalancer for jboss in cluster using the ajp13 with the mod_jk. Each jboss-instance runs on a seperate IP. So I've created virtual hosts for each IP on port 80 and 443. Now I want to setup a virtual host on the main IP on port 8443 where I can create a little control panel to automaticly generate vhost files and JBoss instances. My goal is to manipulate the server only via this contral panel. Therefor I need someting to restart apache gracefully in order to take count of the new created vhost-files. I found the exec command in php and I to restart http I use /etc/init.d/htpd graceful Now how can I put this together in a form with buttons. Do I have to do something for the user that runs the script? Please help!!!
