Updating WordPress: Upgrading php53 on CentOS

If you have a self-hosted WordPress blog, you really ought to keep it up to date. Popular software is a popular security target, and as new exploits are discovered, new patches are deployed. Fortunately, WordPress makes this super-easy. Just go to Dashboard > Updates and you can update with one click. I basically get a free update any time I get it in my head to write something.

Except this morning, when I was told that an update was available, but:

"You cannot update because WordPress 3.2 requires PHP version 5.2.4 or higher. You are running version 5.1.6."

On my CentOS VM, this was addressed by:


sudo yum update
sudo service httpd restart

Actually, it was a little difficult, because we’re replacing php with php53:

0-13:11 djh@www0 ~$ cat /etc/redhat-release

And now I have successfully upgraded via the web UI.

Most days, I am not a CentOS admin, so if there is a better way to have done this, I am keen to hear.
