Scenario:

Here we are trying to help you to fix one of the most common  Yum install error

Error 1:

yum install php
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again

You should try these steps so that the metalinks can be retried to be downloaded again.

yum clean all
yum search php
yum install php

You can see that it is getting downloaded, but you may also be stopped with an error below

GPG error when trying to compare the signature

GPG key retrieval failed: [Errno 14] Could not open/read file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

First see whether the file is there by doing a `ls` as below

ls /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

Most probably you may be getting a file not found message. In any case you need to search Google for  RPM-GPG-KEY-EPEL-6 . You will get the GPG key from internet which you can import as below
