I have a CentOS server that came installed with WHM and cPanel and the corresponding LAMP stack. I disabled Apache and MySQL and replaced them with nginx and PostgreSQL.
...Or at least I thought I did. Apache insists on starting up on boot, blocking the ports nginx needs. So every time the server goes down for maintenance or is restarted for some other reason, Apache starts serving an old "under construction" page we had put up. After being alerted to the issue via a few angry phone calls, I have to shutdown Apache and start up nginx.
chkconfig --list httpd returns:
httpd 0:off 1:off 2:off 3:off 4:off 5:off 6:off
So I don't know what's booting up Apache. Any thoughts on what could be happening?
