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

Let’s add the appropriate repos before we begin

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();
?>

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.
