The greatest fear with adding additional and especially third party repos such as EPEL (we did a blog post on how to install EPEL earlier) is that it MAY overwrite base packages and bring the system to an unstable state.
In this blog post, I will set 1 as the priority (highest) for my CentOS Base repo
So that it becomes
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
name=CentOS-$releasever - Base
name=CentOS-$releasever - Updates
Other repos do not need updating since I have assigned CentOS repos with the highest priority. The default priority for repositories is 99.
All my technical life, I knew and followed this simple rule
New updates to any application or component are meant to improve and fix the bugs present in it. Downloading new updates ensures that you system is up-to-update, has fixes to all those bugs you have been getting annoyed with and more stable.
Unfortunately not every IT department thinks that, especially the one I am facing at work. According to them, the new updates should only be applied IF and only IF they offer some new functionality (duhh!). Hello! what happened to the bug-fixes that are promised with these updates?

I have seen people installing Apache, PHP and MySQL from source code on a production server. You should NEVER, NEVER, NEVER install these packages from source on an RPM or DEB based Linux distributions. Did I say “NEVER” enough times to make your realize that it is not a good practice?
Installing from source is bad idea; there are many reasons for this but the major one is that you will be spending a lot of time keeping the system updated. If you love installing from source then I would suggest using a different distribution e.g. Gentoo.
You can build from source if the package is not available in yum but still, try to use “yum” (or “apt-get” on Ubuntu) because it will save a lot of your time when upgrading your packages.
