I installed Centos 6.3 (minimum), and then: Yum install httpd php php-mysql mysql-server mysql proftpd and download ispconfig3.tar and run "php -q install" on install folder. It starts okie and log on myweb:8080(isp panel) and myweb:80 okie. But only little times, I can't log on, https status 's still running. I ssh to server and /etc/init.d/httpd restart, and log on okie. And after log on myweb:8080 little time it's not running. Please help me, thanks you all!
