Install LEMP (Linux, Nginx, MySQL and PHP) On CentOS Server With AttuneOps

This Blueprint Install LEMP Stack Components On A CentOS Server And Creates A PHP Info File To Verify The Installation

LEMP is a variation of the ubiquitous LAMP stack used for developing and deploying web applications. While LAMP uses Apache as WebServer, its alternative Nginx is used with LEMP stack. LEMP stack consists of the following technologies.

Linux : The Linux® kernel is the main component of a Linux operating system (OS) and is the core interface between a computer's hardware and its processes. Linux provides the base for LEMP stack components, and makes installing the desired applications easy. Most common used Linux distributions are Ubuntu and Debian. Other available Linux distributions are CentOS, RedHat, OpenSuse, and Fedora etc.

Nginx : Nginx is an open source reverse proxy server. It is used to enable HTTP, HTTPS, SMTP, POP3, and IMAP protocols over a network. Nginx can also be used as a reverse proxy, load balancer, mail proxy and HTTP cache. It is main alternative and competitor to Apache Web Server. NGINX Plus is an application delivery platform built on NGINX, an open-source web server and reverse proxy for high-traffic sites.

PHP : PHP is a general-purpose and server-side scripting language that is especially suited for web development. PHP originally stood for Personal Home Page. It was later changed to Hypertext Preprocessor. PHP runs on all major operating systems including Windows, Linux and macOS. PHP supports a wide range of databases, like MySQL, PostgreSQL, MS SQL, db2, Oracle Database, and MongoDB. LEMP stack utilises MYSQL as the database with PHP.

MySQL : MySQL is a Relational Database Management System, it is available as a open-source software under the terms of General Public License. MySQL is backed and maintained by Oracle. MySQL runs on all major operating systems and is easy to setup and uses Structured Query Language (SQL).

Pre-Blueprint Attune setup
  1. On the Inputs tab, create a Linux node for the host you wish to install the stack on.
  2. On the Inputs tab, create Linux credentials to connect to the host you wish to install the stack on.

1 - Install Prerequisite

We will being by installing epel-release respository for this automation task. This makes Nginx package available to be installed by Yum.

The connection details have changed from the last step.

Login as user on node

Connect via SSH
ssh user@hostname
This is a Bash Script make sure you run it with bash -l from a terminal session
# Update yum repository
sudo yum -y update

# Install epel repository
sudo yum -y install epel-release

2 - Install Nginx Web Server

This step installs Nginx web server and configures it to launch at system reboot. Nginx is a light weight web server used in production by Enterprises.

The connection details have changed from the last step.

Login as user on node

Connect via SSH
ssh user@hostname
This is a Bash Script make sure you run it with bash -l from a terminal session
#Install nginx
sudo yum -y install nginx

# Start nginx server
sudo systemctl start nginx 

# Enable nginx server
sudo systemctl enable nginx

3 - Install MySQL (MariaDB) Server

Installs MariaDB package which is a fork of the MySQL Database server.

The connection details have changed from the last step.

Login as user on node

Connect via SSH
ssh user@hostname
This is a Bash Script make sure you run it with bash -l from a terminal session
# Install MariaDB server
sudo yum -y install mariadb-server mariadb

# Enable mariadb server
sudo systemctl enable mariadb

4 - Install PHP7.4 and FPM

Installs PHP version 7.4 and PHP-FPM package which is used as the php interpreter for Nginx.

Login as user on node

Connect via SSH
ssh user@hostname
This is a Bash Script make sure you run it with bash -l from a terminal session
# Install PHP remi repository
sudo yum -y install http://rpms.remirepo.net/enterprise/remi-release-7.rpm

# Enable remi repository
sudo yum-config-manager --enable remi-php74

# Install requiered php plugins 
sudo yum -y install php php-mysqlnd php-fpm

5 - Upload nginx configuration

Uploads PHP configuration file, this enable nginx to support php execution with the help of php-fpm socket.

Login as user on node

Connect via SSH
ssh user@hostname
Deploy archive nginx-php.conf.zip to remote path uploads
  1. Locate Files archive "nginx-php.conf.zip", This can be downloaded from Attune
  2. Copy the Files archive to the server
  3. Extract the root of the Files archive to uploads, relative to the home directory
  4. Check that the files are in the correct location

6 - Upload php-fpm configuration

Uploads php-fpm configuration files, this sets correct FPM parameters for the LEMP stack environment.

Login as user on node

Connect via SSH
ssh user@hostname
Deploy archive php-fpm-www.conf.zip to remote path uploads
  1. Locate Files archive "php-fpm-www.conf.zip", This can be downloaded from Attune
  2. Copy the Files archive to the server
  3. Extract the root of the Files archive to uploads, relative to the home directory
  4. Check that the files are in the correct location

7 - Configure Nginx and PHP FPM

Finally, move the configuration files to their respective directories and restart the servers. To test that PHP is working fine with Nginx, a info.php file is created in the root directory of the server.

Visit http://YOUR_IP/info.php , once this step has been completed to verify the installation.

# Replace nginx default config file
sudo cp ~/uploads/nginx.conf /etc/nginx/nginx.conf

# Replace fpm configuration file
sudo cp ~/uploads/www.conf /etc/php-fpm.d/www.conf

echo '<?php phpinfo();' | sudo tee  /usr/share/nginx/html/info.php

# Restart nginx
sudo service nginx restart
