 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.
[root@mail httpd]# 

What are the consequences of using --skip-broken? Any recommendations?

Answer 1

Your version of php-eaccelerator is tied to your current version of PHP. Normally, this would be updated automatically but I would guess that this package was either installed manually without using a repository, or the repository just doesn't have a version that will work with the newer PHP you want to install.

If you skip-broken or --exclude php-eaccelerator, PHP will upgrade, but that module will likely not work.

That may be perfectly fine if you can then find a new version php-eaccelerator to install seperately afterwards.

Answer 2

Remove default PHP with yum remove php. Then you can update to PHP 5.3.x with

yum update php53

This option became available when Centos 5.6. was released. (in April 2011.)

We are all "frustrated" with RHEL/Centos default php (5.1.6). Also the good idea is using additional repos for php/mysql updates (For example Remi, Utter Ramblings, EPEL, CentOS ALT, etc)...

Best regards

Answer 3

The --skip-broken option, will exclude the package that cause the error. So if, in your case, the package that get failed dependencie is php. so it'll be exclude.

When I encounter this problem, usually, I remove the package dependencie (that can't be update, or already installed), then do a little yum clean-all, and update/install what I want. If everything went well, I look in the rpm depos website (those : pkgs, rpm pbone, rpmfind ) and do a manual installation of the package I removed.

Hope this will help you.
