Perhaps your CMS has an installation guide on it's site
In the GUI (your window manager) you can look at System Settings > Server Settings > Services and you should find httpd (=Apache 2) and mysqld in the list. You can start/stop/restart the services here too. In order for services to work they need to be started.
If something's not installed:
I'm guessing you don't have yum installed (try on the commandline: yum -h), otherwise you could try
which lists the package. If it says "Repo : base" for example then that package is NOT installed or it'll say "Repo : installed". Try httpd, php, mysql.
yum install <package> would install whatever you need.
For up2date (try: up2date -h) you can use: up2date --show-available
That gives you a (long) list of packages NOT installed.
would install MySQL client, there's also a server: mysql-server
You probably need package php-mysql too.
I don't know about zlib, afaik you can install it with yum or up2date too.
For XML I don't know, seems to me like your browser should handle that but I don't know what you need it for.
Aside: I like yum a lot better than up2date, consider installing yum if you don't have it already.
There are some post-installation/initialization steps you need to do.
- Google on: mysql post installation, you should end up on a site like dev.mysql.com
- Go to http://www.php.net/manual/
and select your language, look at the security section in particular
- Check http://httpd.apache.org/docs/2.0/mis...rity_tips.html
Finally, the CMS should probably be installed in the webserver directory, probably /var/www/html/
