Once the installation is complete, enable Nginx (to start automatically upon system boot), start the web server and verify the status using the commands below.
systemctl start nginx
systemctl enable nginx
systemctl status nginx

To check Nginx version.
nginx -v
Output:
[root@vps ~]# nginx -v
nginx version: nginx/1.17.10 (Ubuntu)
Verify that the web server is running and accessible by accessing your server’s IP address.
From your browser,
http://IP_address
we need to make user nginx as the owner of web directory. By default it’s owned by the root user.
chown www-data:www-data /usr/share/nginx/html -R
Install MariaDB Server
MariaDB is a popular database server. The installation is simple and requires just a few steps as shown.
apt install mariadb-server mariadb-client

mariadb-common mariadb-server-10.3 mariadb-server-core-10.3 mysql-common
Once the installation is complete, enable MariaDB (to start automatically upon system boot), start the mariaDB and verify the status using the commands below.
systemctl start mariadb
systemctl enable mariadb
systemctl status mariadb
Output:

Finally, you will want to secure your MariaDB installation by issuing the following command.
mysql_secure_installation
Output:
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
Once secured, you can connect to MySQL and review the existing databases on your database server by using the following command.
mysql -e "SHOW DATABASES;" -p
Output:
root@vps:~# mysql -e "SHOW DATABASES;" -p
Enter password:

Setting Up Server Blocks
You need to remove the file default, located in /etc/nginx/sites-enabled.
rm /etc/nginx/sites-enabled/default
Create new server block file under /etc/nginx/conf.d/ directory.
nano /etc/nginx/conf.d/default.conf
Add following text into the file.
server {
listen 80;
listen [::]:80;
server_name _;
root /var/www/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/php7.4-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;
}
}
Next, test to make sure that there are no syntax errors in any of your Nginx files.
nginx -t
If there aren’t any problems, restart Nginx to enable your changes.
systemctl reload nginx
Test PHP
To test PHP-FPM with Nginx Web server, we need to create a info.php file in the webroot directory.
nano /var/www/html/info.php
Add the following PHP code into the file.
<?php phpinfo(); ?>
Now again, access http://localhost/info.php or http://yourserver-ip-address/info.php
. You should see a page similar to below one.
Done!
