I have used CentOS for the past two years, on all my unmanaged servers. I have learned allot around managing CentOS the past years, and are quite happy. But right before Christmas I got an e-mail from a Norwegian hosting provider saying that they had seen more and more attacks on servers using anything less then PHP ver 5.4.2. I can see that all my CentOS 6.5 servers is using PHP v 5.3.3. But Debian 7 is using PHP 5.4.4
I have now started to test out Debian on a couple of VPS servers. I can see that I have to learn allot more how to do things in Debian. But I have no problems finding good howto guides on the net.
Is it worth it changing from CentOS to Debian? Do any website working on CentOS work on Debian without any change? I'm using Virtualmin and my first test is showing me that all sites is working great, but I have not tested any longer then a few hours.
Any input is important to me.
