Install PHP 7 on CentOS 7

Enabling Remi repository

PHP 7.x packages are available in several different repositories. We’ll use the Remi repository which provides newer versions of various software packages including PHP.

The Remi repository depends on the EPEL repository. Run the following commands to enable both EPEL and Remi repositories:

sudo yum install epel-release yum-utils
sudo yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm

Yum may prompt you to import the repository GPG key. Type y and hit Enter.

In the following sections, we will be covering how to install PHP 7.x by enabling the appropriate Remi repository. If you already have PHP 5.4 installed on your system yum will update the PHP packages.

Installing PHP 7.3 on CentOS 7

PHP 7.3 is the latest stable release of PHP. Most modern PHP frameworks and applications including WordPress, Drupal, Joomla, and Laravel are fully supporting PHP 7.3.

Perform the steps below to install PHP 7.3 on CentOS 7.

Start by enabling the PHP 7.3 Remi repository:

sudo yum-config-manager --enable remi-php73

Install PHP 7.3 and some of the most common PHP modules:

sudo yum install php php-common php-opcache php-mcrypt php-cli php-gd php-curl php-mysqlnd

Verify the PHP installation, by typing the following command which will print the PHP version:

php -v
PHP 7.3.1 (cli) (built: Jan 8 2019 13:55:51) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.3.1, Copyright (c) 1998-2018 Zend Technologies
with Zend OPcache v7.3.1, Copyright (c) 1999-2018, by Zend Technologies

Installing PHP 7.2 on CentOS 7

Use PHP 7.2 only if you’re going to install applications such as Magento 2 that is not compatible with PHP 7.2.

The following steps describe how to install PHP 7.2 CentOS 7.

First enable the PHP 7.2 Remi repository by running the following command:

sudo yum-config-manager --enable remi-php72

Once the repository is enabled install PHP 7.2 and few most common PHP modules:

sudo yum install php php-common php-opcache php-mcrypt php-cli php-gd php-curl php-mysqlnd

Verify the PHP installation:

php -v
PHP 7.2.9 (cli) (built: Aug 15 2018 09:19:33) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies
with Zend OPcache v7.2.9, Copyright (c) 1999-2018, by Zend Technologies

Installing PHP 7.1 on CentOS 7

Follow the steps below to install PHP 7.1.

Enable the PHP 7.1 repository by typing:

sudo yum-config-manager --enable remi-php71

Install PHP 7.1 and few most common PHP modules:

sudo yum install php php-common php-opcache php-mcrypt php-cli php-gd php-curl php-mysql

To verify the installation, run the following command which will print the PHP version:

php -v
PHP 7.1.21 (cli) (built: Aug 15 2018 17:56:55) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.1.0, Copyright (c) 1998-2018 Zend Technologies
with Zend OPcache v7.1.21, Copyright (c) 1999-2018, by Zend Technologies

Configuring PHP 7.x to work with Apache

If you are using Apache as your web server then just restart the Apache service using the following command and you are good to go:

sudo systemctl restart httpd

Configuring PHP 7.x to work with Nginx

Unlike Apache, Nginx doesn’t have built-in support for processing PHP files so we need to install a separate application such as PHP FPM which will handle the PHP files.

To install the PHP FPM package run the following command:

sudo yum install php-fpm

By default PHP FPM will run as user apache on port 9000. We’ll change the user to nginx and switch from TCP socket to Unix socket. To do so edit the lines highlighted in yellow:

/etc/php-fpm.d/www.conf
...
user = nginx
...
group = nginx
...
listen = /run/php-fpm/www.sock
...
listen.owner = nginx
listen.group = nginx

Make sure the /var/lib/php directory has the correct ownership:

chown -R root:nginx /var/lib/php

Once you made the changes, enable and start the PHP FPM service:

sudo systemctl enable php-fpmsudo systemctl start php-fpm

Next, edit the Nginx virtual host directive and add the following location block so that Nginx can process PHP files:

server {

# . . . other code

location ~ \.php$ {
try_files $uri =404;
fastcgi_pass unix:/run/php-fpm/www.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}

For the new configuration to take effect, restart the Nginx service:

sudo systemctl restart nginx

Conclusion

You have learned how to install PHP 7 on your CentOS server and how to configure your web server to be able to handle PHP files.
