I have a VPS with WHM/Cpanel from GoDaddy (2GB Gen3 managed VPS). My requirement is to be able to install the latest version of WordPress and SSL certificates from Lets Encrypt / default SSL using AutoSSL in Cpanel.

PHP version is 5.4 and do not have the Let's Encrypt SSL / AutoSSL option in Cpanel. Need to run a few dynamic sites on current version of PHP.

Tried to update PHP using EasyApache update from WHM but getting YUM Failure error.

System details are as follows.
Linux, CENTOS 6.7 x86_64, WHM 11.50.1 (build 3), Apache/2.2.29 (Unix), mod_ssl/2.2.29, OpenSSL/1.0.1e-fips, mod_bwlimited/1.4, MySQL Community Server (GPL) v5.5.42, PHP Version 5.4.33
