[CentOS] App add/delete and changing from CD install to LAN

[Benjamin Smith]

Yum is a really, really nice tool to know! Now that I've gotten familiar with 
it, I now setup servers with no package groups installed, and just use yum to 
get whatever I need when I need it. 

To see a list of all rpms available via yum 

	yum list  

This can be somewhat slow, so what I tend to do is 

	yum list > ~/rpmlist 

and then grep that file. Eg: 

	grep -i thunder ~/rpmlist 

You can also install groups of items, (EG: All the "KDE" stuff) using 
groupinstall. EG: 

	yum groupinstall kde 

And to get a list of groups... 

	yum grouplist 

Here are some neat tricks I've discovered...

To remove all of packages matching a pattern, and all dependencies, in this 
case, postgresql: 

	yum remove `rpm -qa | grep postgres` 

Let's say you have some RPMs in a directory, and want to install them along 
with the dependencies: (This is one I discovered just yesterday!) 

	yum install ./postgres*
