Error while using rpm to install a package on CentOS 6 - file x from install of xx conflicts with file from package xxx

Summary: 

File x from install of xx conflicts with file from package xxx.

This happened when i was trying to install OpenSSL on CentOS release 6.3

Problem or Goal: 

The problem here is Conflicting Files. If you attempt to install a package that contains a file which has already been installed by another package, the following is displayed:

Cause: 

This means OpenSSL was already installed on this server

[root@localhost tmp]# openssl version

OpenSSL 1.0.0-fips 29 Mar 2010

[root@localhost tmp]# 

Solution: 

To make RPM ignore this error, use the --replacefiles option:

This will actually upgrade or downgrade your installation depending on the version of the installation package you are using!

[root@localhost tmp]# rpm -ivh --replacefiles openssl10-libs-1.0.1e-1.ius.centos6.x86_64.rpm 

warning: openssl10-libs-1.0.1e-1.ius.centos6.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID 9cd4953f: NOKEY
