How to Install PHP 7, NGINX & MySQL 5.6 on CentOS/RHEL 7.4 & 6.9

Few days back PHP version 7.2 has been released. Which has a number of changes and improvements over PHP version 7.X. This article will help you to install PHP 7, NGINX and MySQL 5.6 on CentOS / RHEL 7.4 & 6.9 operating systems. This tutorial has been tested with CentOS 7.4, 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 the 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 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 http://repo.mysql.com/mysql-community-release-el6-5.noarch.rpm

Step 2 – Install PHP 7

Now install PHP 7 packages from remi-php72 rpm repository using the following command.

1
# yum --enablerepo=remi-php72 install php

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

1
# yum --enablerepo=remi-php72 search php

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

3
# yum --enablerepo=remi-php72 install php-mysql php-xml \

php-soap php-xmlrpc php-mbstring php-json php-gd php-mcrypt

Step 3 – Install NGINX

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

1
# yum install nginx

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

1
2
# 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.

1
# 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.

1
2
# systemctl start mysqld.service
# mysql_secure_installation

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

1
2
# 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.

1
# yum --enablerepo=remi-php72 install php-fpm

Step 6 – Create Nginx VirtualHost

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

1
# sudo vi /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 the following command.

3
# firewall-cmd --permanent --zone=public --add-service=http
# firewall-cmd --permanent --zone=public --add-service=https
# firewall-cmd --reload

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