What is the difference between yum update and Yum upgrade?
If a particular software is added to the “yum update” or “yum upgrade” command like then only the given software package and its dependencies are processed by the commands. This is the short version of the answer. Let me expand what is written above with some more details. Let’s have a second look at the following words
What should I do if my yum update is not working?
Clear yum cache, yum clean all, followed by yum makecache to refresh it. If this doesn’t help, get a new CentOS repository definition file from the official website.
Why is Yum not installing on CentOS 7?
No repositories available Some CentOS 7 installations don’t configure any yum repositories by default, so yum will be unable to install or update any package.

Ie, yum’s update process is fundamentally broken.

Do you need to specify rpm in yum update PHP?
Yes. You need to specify the full RPM desired. Instead of just saying yum update php you’d have to do something more like yum install php-5.3.3-27.el6_5. exactly what Tom said. To see what is available: Yum ignores specific versoins and will always install the latest version available.
