Installing PHP 5.5 on RHEL 7 and CentOS 7
|
|
=========================================
|
|
|
|
PHP 5.4 has been end-of-life since September 2015 and is no longer supported by the PHP team. RHEL 7 still ships with PHP 5.4, and Red Hat supports it. ownCloud also supports PHP 5.4, so upgrading is not required. However, it is highly recommended to upgrade to PHP 5.5+ for best security and performance.
|
|
|
|
**Before upgrading, evaluate all of your PHP apps for compatibility with PHP 5.5.**
|
|
|
|
RHEL 7 Upgrade to PHP 5.5
|
|
-------------------------
|
|
|
|
To upgrade to PHP 5.5, you must use the Software Collections (SCL) repository to be in compliance with your RHEL support contract, and not any other third-party repository. Follow these steps to install PHP 5.5 from SCL. First you must use your Subscription Manager to enable SCL::
|
|
|
|
subscription-manager repos --enable rhel-server-rhscl-7-eus-rpms
|
|
|
|
Then install PHP 5.5 and these modules::
|
|
|
|
yum install php55 php55-php php55-php-gd php55-php-mbstring
|
|
|
|
You must also install the updated database module for your database. This installs the new PHP 5.5 module for MySQL/MariaDB::
|
|
|
|
yum install php55-php-mysqlnd
|
|
|
|
Activate the new PHP version permanently::
|
|
|
|
source /opt/rh/php55/enable
|
|
|
|
Disable loading the old PHP Apache module by changing its name. Look in ``/etc/httpd/conf.d/`` to verify the module name::
|
|
|
|
mv /etc/httpd/conf.d/php.conf /etc/httpd/conf.d/php.conf.old
|
|
|
|
Copy the PHP 5.5 Apache modules from /opt/rh/php55/::
|
|
|
|
cp /opt/rh/httpd24/root/etc/httpd/conf.d/php55-php.conf /etc/httpd/conf.d/
|
|
cp /opt/rh/httpd24/root/etc/httpd/conf.modules.d/10-php55-php.conf /etc/httpd/conf.modules.d/
|
|
cp /opt/rh/httpd24/root/etc/httpd/modules/libphp-php55.so /etc/httpd/modules/
|
|
|
|
Then restart Apache::
|
|
|
|
service httpd restart
|
|
|
|
Verify with ``phpinfo`` that your Apache server is using PHP 5.5 and loading the correct modules; see :ref:`label-phpinfo` to learn how to use phpinfo.
