How to Install LEMP Stack (Nginx, MySQL, PHP7.2) on Ubuntu 16|18.04|20

LEMP Stack – this is a combination of software packages – Linux, Nginx, MySQL and PHP.

Prerequisite:

Ubuntu Server 16, 18 or 20th version.
Basic Knowledge of linux commands.

What we will do?

Install Nginx
Install MySQL
Install PHP-FPM
Configure Nginx and PHP-FPM
Testing

Step 1: Update Software Packages

Before we install the LEMP stack, it’s a good practice to update repository and software packages by running the following commands on your Ubuntu OS.

sudo apt update -y && sudo apt upgrade -y

Step 2: Install Nginx Web Server

Nginx is a high performance web server and very popular these days. It also can be used as a reverse proxy and caching server. Enter this command to install Nginx Web server.

sudo apt install nginx -y

After installing Nginx, the commands below can be used to start and enable Nginx service to always start up with the server boots.

sudo systemctl start nginx.service && sudo systemctl enable nginx.service

Now check out its status.

systemctl status nginx

Step 3: Install MySQL Database Server

sudo apt-get install mysql-server

After it’s installed, MySQL server should be automatically stared. Use systemctl to check its status.

systemctl status mysql

If it’s not running, start and enable service with the below command:

sudo systemctl start mysql && sudo systemctl enable mysql

Step 4: Install php7.2

To install another php version check our blog here.

Add apt repository and Update the system.

sudo apt install software-properties-common -y && sudo add-apt-repository ppa:ondrej/php

sudo apt update -y

sudo apt install php7.2 php7.2-mysql php-common php7.2-fpm php7.2-cli php7.2-common php7.2-json php7.2-opcache php7.2-readline php7.2-mbstring php7.2-gd php7.2-zip php7.2-xmlrpc -y

After installing PHP, run the commands below to find the version installed on the server…

php --version

Veirfy php fpm service is running or not.

sudo systemctl status php7.2-fpm

if not then use below command to start and enable.

sudo systemctl start php7.2-fpm && sudo systemctl enable php7.2-fpm

Step 5: Add new VirtualHost Configuration file in Nginx.

vim /etc/nginx/conf.d/newsite.conf

server {
listen 80;
listen [::]:80;
root /usr/share/nginx/html;
index index.php index.html index.htm;
server_name domainname.com ;
location / {
try_files $uri $uri/ /index.php?/$request_uri;
#try_files $uri /index.php?/$request_uri;
}
error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;

location = /50x.html {
root /usr/share/nginx/html;
}
location ~ \.php$ {
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
fastcgi_read_timeout 240;
}
location ~ /\.ht {
deny all; }
}

Save and exit and first check the syntax status of nginx configuration file then, restart the nginx service

sudo nginx -t

if syntax is OK it’s Good else we have to check the configuratioin file error.

sudo systemctl restart nginx

Step 6: Testing

To test PHP settings with Nginx, create a phpinfo.php file in Nginx root directory by running the commands below.

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

<?php phpinfo( ); ?>

Save the file.. then browse to your server hostname followed by info.php
http://domainname.com/info.php
You should see PHP default test page…

Using the above tutorial you have learned How To Install LEMP Stack on Ubuntu Servers.
