Is it safe to install GD?
some time ago I was given the job of creating and installing several websites on a Fasthosts dedicated linux Fedora Core server for a client. I have no previous experience of Linux. Managed to stumble my way around and all sites are up and running fine. I now need GD image support for a new site about to be installed on the same server, I have read I can use a package installer by typing 'yum install gd' or 'yum install php-gd' but what exactly does this do? Is it safe to do on a live server? Do I risk taking down the already live sites, will it overwrite any changes I have made to httpd.conf etc? At the moment I control the server via 'matrix' control panel - to re-start apache etc. Do I risk seperating the control panel from apache? And if I do install via yum how long would it take?
I am just worried I type a command in that kills a server supporting several E-commerce sites and have no idea how to start fixing it - not knowing linux! (I know php not linux!)
Thanks in advance - n00b.
