How to Install PHP 7, NGINX & MySQL 5.6 on CentOS/RHEL 7.1 & 6.7

Few days back PHP version 7.0 has been released. Which has number of changes and improvements over PHP version 5.X. This article will help you to install PHP 7, NGINX and MySQL 5.6 on CentOS / RHEL 7.1 & 6.7 operating systems. This tutorial has been tested with CentOS 7.1, so all the services command are used with systemctl, For CentOS 6 users change all systemctl command correspondence service command.

Step 1. Setup Yum Repository

In the first step install all the required yum repositories in your system used in remaining tutorial for various installations. You are adding REMI, EPEL, Webtatic & MySQL community server repositories in your system.

CentOS / RHEL 7

# yum install epel-release # rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm # rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm # rpm -Uvh http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm 

CentOS / RHEL 6

# yum install epel-release # rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm # rpm -Uvh https://mirror.webtatic.com/yum/el6/latest.rpm # rpm -Uvh http://repo.mysql.com/mysql-community-release-el6-5.noarch.rpm 

Step 2. Install PHP 7

Now install php 7 packages from webtatic rpm repository using following command.

# yum install php70w 

Now install required php modules. Use following command to list available modules in yum repositories.

# yum search php70w 

Now check all listed modules in above command and install required modules like below.

# yum install php70w-mysql php70w-xml php70w-soap php70w-xmlrpc # yum install php70w-mbstring php70w-json php70w-gd php70w-mcrypt 

Step 3. Install NGINX

NGINX is the popular web server used on Linux systems. Let’s install Nginx web server using following command on your system.

# yum install nginx 

Now start nginx service and enable to start on boot using below commands.

# systemctl enable nginx.service # systemctl start nginx.service 

Step 4. Install MySQL 5.6

In step 1 we already have installed required yum repository in your system. Lets use following command to install MySQL server on your system.

# yum install mysql-server 

You need to execute mysql_secure_installation once after installation of MySQL server using following command. First it will prompt to set a password for root account, after that ask few questions, I suggest to say yes ( y ) for all.

# systemctl start mysqld.service # mysql_secure_installation 

Now restart MySQL service and enable to start on system boot.

# systemctl restart mysqld.service # systemctl enable mysqld.service 

Step 5 — Setup PHP-FPM

Now use following command to install php7 fpm package using following command.

# yum install php70w-fpm 

Step 6 — Create Nginx VirtualHost

Finally do the configuration of Nginx VirtualHost. For this example we are editing default configuration file.

$ sudo nano /etc/nginx/conf.d/example.conf 

and make changes as below.

server {         listen   80;          root /var/www;         index index.php index.html index.htm;         server_name  example.com www.example.com;          location / {                 try_files $uri $uri/ /index.html;         }          error_page 404 /404.html;         error_page 500 502 503 504 /50x.html;         location = /50x.html {               root /usr/share/nginx/www;         }          location ~ .php$ {                 try_files $uri =404;                 fastcgi_pass 127.0.0.1:9000;                 fastcgi_index index.php;                 fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;                 include fastcgi_params;         } } 

You have to do the same changes in all Virtual Hosts configured.

Step 7 – Restart Services

After installing all services on your system, start all required services.

# systemctl restart nginx.service # systemctl restart php-fpm.service 

Step 8. Open Port in Firewall

Finally open firewall ports for http (80) and https (443) services using following command.

# firewall-cmd --permanent --zone=public --add-service=http # firewall-cmd --permanent --zone=public --add-service=https # firewall-cmd --reload 

Step 9. Verify Setup

Let’s check the installed versions of packages on system using following commands one by one.

# php -v  PHP 7.0.2 (cli) (built: Jan  9 2016 14:00:11) ( NTS ) Copyright (c) 1997-2015 The PHP Group Zend Engine v3.0.0, Copyright (c) 1998-2015 Zend Technologies 

# nginx -v  nginx version: nginx/1.6.3 

Finally verify installation of PHP 7 with NGINX. Let’s create a file index.php on website document root using following content.

<?php phpinfo(); ?>

1 2 3

<?php phpinfo(); ?>

Now browse this file in web browser. It will so all the details about version’s and installation.

You have successfully configured LEMP Stack setup on your CentOS / RHEL 7.1 & 6.7 system.
