PHP 7 comes with numerous new and improved features. One of the most noticeable is the new Zend Engine version. Also, other important improvements are the enhanced performance and significantly reduced memory usage. Thus, PHP 7 can be up to twice as fast as PHP 5.6.
To install PHP 7 on an CentOS VPS, you need to login to your server via SSH. Once you are logged in, update all your system software to the latest version using the command below:
Once the update of your system is completed, you can go ahead and add the required repositories to yum.
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
Now, install PHP 7 using the following command:
yum install php70w
The installation should take a few moments. Once it is completed, you can ensure that the latest stable release of PHP 7 is installed on your system by using the command:
You should see something like this:
PHP 7.0.0 (cli) (built: Dec 2 2015 20:42:32) ( NTS ) Copyright (c) 1997-2015 The PHP Group Zend Engine v3.0.0, Copyright (c) 1998-2015 Zend Technologies
If you like to search all the available PHP 7 modules you can use to command:
yum search php70w
To install specific PHP 7 modules like the module that allows PHP applications to use MySQL databases, you can use the command below:
yum install php70w-mysql
To test the functionality of PHP 7 on your CentOS VPS you can create a simple PHP info file and place it in your web server’s document root. Navigate to your web server’s document root:
Create a PHP info file using nano:
Paste the following content into that file:
<?php phpinfo(); ?>
Save the file and close it. Also, change the ownership of the file and make Apache the owner of that file:
chown apache: info.php
Do not forget to restart your Apache web server if you haven’t restarted it yet so the installation changes can take effect:
systemctl restart httpd
The last thing is to access the file using a web browser. Open your favorite web browser and navigate to the following address:
Of course, we are using the IP address 188.8.131.52 for testing purposes only, so you should make sure that you are using your actual server’s IP address. You should see a page with the current PHP information such as version, compilation options, extensions, loaded configuration files etc.
Of course you don’t have to do any of this if you use one of our Linux VPS hosting services, in which case you can simply ask our expert Linux admins to install PHP 7 for you. They are available 24×7 and will take care of your request immediately.
