PHP installation conflicts on Centos6

Posted by: admin July 12, 2020 Leave a comment


I’m new to server and linux and I ran into some problems. I’m trying to update my PHP by looking for linux commands through the net. Some commands ran perfectly but some not.

I tried using this command to install php-gd since I have this error message ‘Required GD library is missing’. So, I tried to run this below:

yum install php-gd

However, it give me this error message below:

php56w-common conflicts with php-common-5.3.3-46.el6_6.x86_64

Here are some info on my server:

[[email protected] ~]# rpm -ql php
package php is not installed

[[email protected] ~]# rpm -qa php\*

[[email protected] ~]# rpm -Va php\*
S.5....T.  c /etc/php.ini
[[email protected] ~]# which php

[[email protected] ~]# php -v
PHP 5.6.11 (cli) (built: Jul 10 2015 22:43:20)
Copyright (c) 1997-2015 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2015 Zend Technologies

Do you know what have I done wrong upgrading my php? Should I remove all php files on my server and reinstall? How?

How to&Answers:

Solved it by removing all php using “yum remove php php-common”

and modified the filename “remi.repo” under the folder /etc/yum.repos.d like below:

name=Remi's PHP 5.6 RPM repository for Enterprise Linux 6 - $basearch
# WARNING: If you enable this repository, you must also enable "remi"

making sure that php56 is enabled=1.


Go to /etc/yum.repos.d.
Remove the extra repository that you can see in your complete error message.


You should run:

yum install php56w-gd

So when install php-extension have error:

*-common conflicts with php-common-5.3.3-46.el6_6.x86_64

Just type *-extension


yum install php-fpm have error

Error: php56u-common conflicts with php-common-5.3.3-46.el6_7.1.x86_64

then you should run

yum install php56u-fpm

The reason of this error is you install a php version don’t match the system repo version. So yum get a version of the system repo, but this don’t compatible with the php version you have installed. When you specific the php version, yum get the right version, so happy!


If you are using Centos 6.7 and have php 5.6 installed, the following command worked for me:

sudo yum install php56w-pecl-xdebug.x86_64 (I was installing xdebug, not GD)

I found this by running yum search php56
