I just Installed Cent OS 6.5 and I am amazed with a few things.
Why the PHP version is only 5.3.3, MySQL 5.1.73, Apache 2.2.15?
If I run the yum commands to update them no updates are found.
Is there a reason the default installation contains so old versions and how to update them to the latest one please?
Running these two commands should install a newer version of the EPEL repo, enabling you to install a newer version of PHP, etc, but you should find the repository which has the versions which you require.
wget http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
rpm -ivh epel-release-6-8.noarch.rpm
Please try below
yum update php*
If you have rpm package then you can use rpm -U option to upgrade existing packages.
