I need to upgrade PHP version on my dedicated server. I currently have 5.1.6 (apache2handler) installed. I have not done this before, therefore a bit nervous.
Also my OS: Apache Version (Apache/2.2.3 (CentOS))
Quick search shows that all I need to do is run up2dat/yum or apt-get.
I assume I need to login as root using shell program, like putty, right? Do I go to the root level and then type up2dat/yum?
Do I need to back up all my sites or this upgrade should not affect my storage?
I am not sure I want to go though removing PHP and installing new one. I am not really savvy in server administration and the prospect of loosing some of my custom setups does not sit well... Any news on perhaps them making it available via normal upgrade?
A bit confused.
