PHP not working CentOS 6 after yum update

Question

I had some problems running yum update and did the followingn steps to make it work:

1. sudo yum --enablerepo=remi,remi-php55 -y remove memcached - this simply removed memcached, one of the packages giving errors
2. sudo yum --enablerepo=remi,remi-php55 -y remove php-pear - this removed more than I bargained for..

Then I've restarted apache and mysql.

Now when I go to any of the (Wordpress) websites on this server, they either display the Apache 2 Test Page or the contents of index.php as plain text (no php execution).

I looked around on Stackoverflow and found some stuff on adding: LoadModule php5_module modules/libphp5.so

But unfortunately that file does not exist. locate libphp5.so gives /usr/lib64/httpd/modules/libphp5.so but LoadModule php5_module /usr/lib64/httpd/modules/libphp5.so gives an error when restarting apache..

I think I've removed more php packages than intended, but I'm not sure which packages are missing and should be installed again. Can anyone point me in the right direction? And tell me wether I should reinstall apache or not? I'd rather not lose any config..

Answer 1

as stated in the error-message, there's an issue because it can not access the 'shared object file'. This can happen after installing new stuff and not running ldconfig. So, stop httpd, install your php modules and run ldconfig, then restart apache.

# ldconfig
# apachectl start 

Answer 2

Eventually I solved it somehow. I removed and (re)installed everything from httpd, php, php-common, php-cli, php-pear, php-mysql and also installed httpd-devel and php-devel

In this process I also manually created a php.conf in /etc/httpd/conf.d/

I also ran this from the centos forums: rpm -qa 'php*' rpm -V php

Eventually the correct php.conf was created in this process and after restarting apache everything is working again.
