Nginx, MariaDB and PHP7.2 are called (LEMP).
You can follow the steps below to install LEMP on Ubuntu 18.04 LTS –
1. Update the Ubuntu Package.
# sudo apt update
# sudo apt upgrade
2. Install Nginx Webserver; it is a high-performance server and is used as Reverse Proxy.
# sudo apt install Nginx
3. Start and enable Nginx.
It will auto-start Nginx at boot time.
# sudo systemctl start nginx
# sudo systemctl enable nginx
4. You can check the Nginx Version with the below command.
# nginx -v
nginx version: nginx/1.14.0 (Ubuntu)
You can access the server IP Address in Browser, which will bring the default Nginx page.
We can set www-data (Nginx user) as the owner of the web directory.
# sudo chown www-data:www-data /usr/share/nginx/html -R
5. Install MariaDB with the command below; MariaDB is a replacement for MySQL.
# sudo apt install mariadb-server mariadb-client
6. Start and enable the MariaDB; it will auto-start it at boot time.
# sudo systemctl start mariadb
# sudo systemctl enable mariadb
7. Run the below command for the post-installation security script.
# sudo mysql_secure_installation
8. Enter the MySQL root password, confirm the password, and set the required configuration.
9. Verify the MariaDB version with the below command –
# mariadb –version
It will give the below output –
# mariadb Ver 15.1 Distrib 10.1.43-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2
10. PHP 7.2 is included with the default Ubuntu Repository for 18.04. However, please enter the below command to install php7.2 with some common extensions.
# sudo apt install php7.2 php7.2-fpm php7.2-mysql php-common php7.2-cli php7.2-common php7.2-json php7.2-opcache php7.2-readline php7.2-mbstring php7.2-xml php7.2-gd php7.2-curl
11. Start and enable the PHP 7.2-fpm; it will auto-start the PHP at boot time.
# sudo systemctl start php7.2-fpm
# sudo systemctl enable php7.2-fpm
12. Run the below command to remove the default symlink in the sites-enabled directory.
# sudo rm /etc/nginx/sites-enabled/default
13. Create a new server block file inside /etc/nginx/conf.d/ directory.
# sudo nano /etc/nginx/conf.d/default.conf
14. Add the below text in default.conf
server {
listen 80;
listen [::]:80;
server_name _;
root /usr/share/nginx/html/;
index index.php index.html index.htm index.nginx-debian.html;
location / {
try_files $uri $uri/ /index.php;
}
location ~ \.php$ {
fastcgi_pass unix:/run/php/php7.2-fpm.sock;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
include snippets/fastcgi-php.conf;
}
# A long browser cache lifetime can speed up repeat visits to your page
location ~* \.(jpg|jpeg|gif|png|webp|svg|woff|woff2|ttf|css|js|ico|xml)$ {
access_log off;
log_not_found off;
expires 360d;
}
# disable access to hidden files
location ~ /\.ht {
access_log off;
log_not_found off;
deny all;
}
}
15. Save and close it, and restart the Nginx service.
# sudo systemctl reload nginx
16. We will test the PHP-FPM with the NGINX webserver.
Let us create the phpinfo.php page in the root directory.
# sudo nano /usr/share/nginx/html/info.php
17. Paste the php info code as shown below –
<?php phpinfo();>
