Install Nginx, MySQL, PHP, APCu on CentOS 7

Published on April 10, 2019 2 min read

In this tutorial, we are going to install Nginx, MySQL, PHP, APCu on CentOS 7.

Table of Contents

Let’s see the steps:

  1. Login to Server
  2. Install Nginx
  3. Install MySQL
  4. Install PHP with PHP-FPM
  5. Configure PHP-FPM
  6. Configure Nginx to Process PHP
  7. Test PHP Processing
  8. Install APCu (Cache)

Step 1 : Login to Server

At first, we need to login to our server via SSH. Open your terminal and run this command:

ssh root@IPaddress -p PORT

Step 2 : Install Nginx

Make nginx.repo file:

sudo nano /etc/yum.repos.d/nginx.repo

Now copy and paste this code to nginx.repo file (SHIFT+INS):

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/mainline/centos/7/$basearch/
gpgcheck=0

Run this command to install Nginx:

sudo yum install nginx

Start Nginx server:

sudo systemctl start nginx

Enable Nginx to start at boot:

sudo systemctl enable nginx

Nginx is installed. Visit your website by entering IP address on a browser: http://ip_address/

Step 3 : Install MySQL

Run this command to install MariaDB:

sudo yum install mariadb mariadb-server

Start MariaDB server:

sudo systemctl start mariadb

Enable MariaDB to start at boot:

sudo systemctl enable mariadb

Run the mysql_secure_installation the script which will perform several security-related tasks:

sudo mysql_secure_installation

Step 4 : Install PHP with PHP-FPM

We need two repositories. The first one is: EPEL. Run this command:

sudo yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

The second one is: REMI. To install, run this command:

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

Now we need to install yum-utils package by running this command:

sudo yum install yum-utils

We are going to install PHP 7.3. You can install another version too.

sudo yum-config-manager --enable remi-php73
Now install PHP 7.3 with all necessary modules
sudo yum install php php-fpm php-common php-mcrypt php-cli php-gd php-curl php-mysql php-ldap php-zip php-fileinfo php-mbstring php-bcmath

To check the installed version of PHP, run this:

php -v

Step 5 : Configure PHP-FPM

Open php.ini file:

sudo nano /etc/php.ini

and add this line to the configuration file:

cgi.fix_pathinfo=0

Save and close the file. Next, open www.conf file:

sudo nano /etc/php-fpm.d/www.conf

Now find user and group and change their values to centos.

user = centos
group = centos

Now find listen.owner and listen.group and change their values to centos.

listen.owner = centos
listen.group = centos

Last, find listen parameter and change the line to:

listen = /var/run/php-fpm/php-fpm.sock

Save & close the file and start the PHP processor by typing:

sudo systemctl start php-fpm

Enable php-fpm to start on boot:

sudo systemctl enable php-fpm

Step 6 : Configure Nginx to Process PHP

Remove nginx.conf and re-create nginx.conf file by these commands :

# remove
sudo rm /etc/nginx/nginx.conf
# add again
sudo nano /etc/nginx/nginx.conf

Now paste this code (SHIFT+INS):

user centos;
worker_processes auto;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

events {                                                                     
    worker_connections  1024;
}                                                                            
                                                      
http { 
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';
      
    access_log  /var/log/nginx/access.log  main;
    
    sendfile        on; 
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;
    #
    include /etc/nginx/conf.d/*.conf;
}

Save and close the file. Now remove default.conf and re-create default.conf file:

# remove
sudo rm /etc/nginx/conf.d/default.conf
# add again
sudo nano /etc/nginx/conf.d/default.conf

Paste this code now (replace server IP):

server {
        listen 80;
        server_name 3.85.235.68;

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

        location / {
            try_files $uri $uri/ /index.php?$query_string;
        }

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

        location ^~ /.well-known/acme-challenge/ {
            allow all;
            default_type "text/plain";
        }

        location ~ /\. {
            deny all;
        }
}

Save and close the file. Restart Nginx to make the necessary changes:

sudo systemctl restart nginx

Step 7 : Test PHP Processing

In CentOS 7, this directory is located at /usr/share/nginx/html/. Create a file by typing:

sudo nano /usr/share/nginx/html/info.php

Write this code to the info.php:

<?php phpinfo(); ?>

Save and close the file. Now the address you want to visit will be:

# Open in a web browser:
http://your_server_IP/info.php

You will see like this:

Step 8 : Install APCu (Cache)

Run this command to install APCu:

sudo yum install php-pecl-apcu

By entering this command, you can install dependency packages for APCu:

sudo yum install php-pear php-devel httpd-devel pcre-devel gcc make
Finally, restart your web server to enable APCu:
sudo systemctl restart php-fpm

Now take a look at the info.php:
