PHP7 brings significant improvements in performance and new features compared to its predecessors. If you're running CentOS 6 and looking to upgrade to PHP7, this guide will help you through the installation process using the Remi repository. We will cover the basic steps and provide additional instructions for setting up PHP7 for Nginx.

Prerequisites

Before you begin, ensure you have the following:

A CentOS 6 server
Root access or a user with sudo privileges

Step 1: Update the System

Start by updating your system to ensure all existing packages are up to date.


yum update -y

Step 2: Install Required Packages

Install wget and yum-utils to facilitate the installation of the Remi repository.


yum install wget yum-utils -y

Step 3: Add the Remi Repository

Download and install the Remi repository.


wget http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
rpm -Uvh remi-release-6.rpm

Step 4: Enable the Remi-PHP70 Repository

Enable the Remi-PHP70 repository to access PHP7 packages.


yum-config-manager --enable remi-php70

Step 5: Install PHP7

Install PHP7 from the Remi repository.


yum install php --enablerepo=remi-php70 -y

Step 6: Verify PHP Installation

Check the PHP version to ensure PHP7 is installed correctly.


php -v

You should see an output similar to:


PHP 7.0.x (cli) (built: ...)

Step 7: Install PHP7 for Nginx

Since Nginx uses PHP-FPM and PHP-MySQL, install these packages as well.


yum install php-fpm php-mysql --enablerepo=remi-php70 -y

Configure PHP-FPM

Start and enable PHP-FPM to run on boot.


service php-fpm start
chkconfig php-fpm on

Configure Nginx

Ensure your Nginx configuration is set to use PHP-FPM. Edit your Nginx configuration file (e.g., /etc/nginx/nginx.conf or a specific site configuration in /etc/nginx/conf.d/).

Here is a basic example for the server block:


server {
    listen       80;
    server_name  your_domain.com;

    root   /usr/share/nginx/html;
    index  index.php index.html index.htm;

    location / {
        try_files $uri $uri/ =404;
    }

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }
}

Restart Nginx to apply the changes.


service nginx restart
