Upgrading to PHP5/MySQL5 under CentOS 4.5

categories:

I’m planning on moving to PHP 5 and MySQL 5 on our CentOS 4 production server.

Before doing anything on the production machine, I’m testing the process on a fresh installation of CentOS on a virtual machine…

I first tried to upgrade PHP… MySQL updates should be pulled out from the repository as well but it didn’t work.

<code># yum update php --enable=centosplus

As you can notice, it pulls out 2 different versions of the package “mysql”.

This is the explanation of the issue given on IRC :

wolfy, toracat : well i'm working on a fresh install on a VM before I do anything on the production server.. So i assume I did nothing wrong.. it does try to pull out both version because it complains they are conflicting file /usr/bin/mysql conflicts between attempted installs of mysql-5.0.27-1.el4.centos and mysql-5.0.48-1.el4.centos sw: what command are you running for the install? Evolution, yum update php --enablerepo=centosplus sw: that only pulls in php-mysql, which just needs mysql. you likely have mysql-server already installed and that's what's conflicting. Evolution: but shouldn't the new mysql obsolete the older one ? the installed version of mysql-server is mysql-server-4.1.20-2.RHEL4.1.0.1 wolfy: it should and does, but php packaging changed, and that's caused a few issues in the upgrade. it's a valid mixed arch case, as php-pear went from an i386 arch to a noarch

The working command :

<code># yum --enablerepo centosplus install php php-pear php-mysql mysql mysql-server
