Bug/ feature found
Apparently I found a bug/feature, but I think it's a bug.
In /etc/httpd/conf/sites-available I have several .vhosts files, and today I noticed that some of them are equal in the 2 nodes of the cluster, and some of them are different. The ones that have equal correspond to websites in which the php mode is: "fast-CGI". Whenever I change this mode to "php mod" I get different .vhosts files.
What happens is that the file in the master node is updated and in the slave remains the same.
Can you help me correct this?
