How to Install LEMP Stack (Nginx, MariaDB, PHP7.2) on CentOS 8
Install Nginx Web Server on CentOS 8
First, we will start by installing the Nginx web server. To complete the installation, use the following command:
yum install nginx -y
Output:
[root@my ~]# yum install nginx -y

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
Output:
[root@my ~]# systemctl start nginx
[root@my ~]# systemctl enable nginx
Created symlink /etc/systemd/system/multi-user.target.wants/nginx.service → /usr/lib/systemd/system/nginx.service.

Check Nginx version
nginx -v
Output:

nginx version: nginx/1.14.1
To make your pages available to public, you will have to edit your firewall rules to allow HTTP requests on your web server by using the following commands.
firewall-cmd --permanent --zone=public --add-service=http
firewall-cmd --permanent --zone=public --add-service=https
firewall-cmd --reload
Output:
[root@server ~]# firewall-cmd --permanent --zone=public --add-service=http
success
[root@server ~]# firewall-cmd --permanent --zone=public --add-service=https
success
[root@server ~]# firewall-cmd --reload
success
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 nginx:nginx /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.
yum install mariadb-server mariadb -y
Output:
[root@server ~]# yum install mariadb-server mariadb

Finally, you will want to secure your MariaDB installation by issuing the following command.
mysql_secure_installation
Output:
[root@server ~]# mysql_secure_installation
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@server ~]# mysql -e "SHOW DATABASES;" -p
Enter password:

Once the installation is complete, enable php-fpm (to start automatically upon system boot), start the php-fpm and verify the status using the commands below.
systemctl start php-fpm
systemctl enable php-fpm
systemctl status php-fpm
Output:
[root@my ~]# systemctl start php-fpm
[root@my ~]# systemctl enable php-fpm
Created symlink /etc/systemd/system/multi-user.target.wants/php-fpm.service → /usr/lib/systemd/system/php-fpm.service.

Loaded: loaded (/usr/lib/systemd/system/php-fpm.service; enabled; vendor pre>
By default, PHP-FPM runs as the apache user. Since we are using Nginx web server, we need to change following line.
vi /etc/php-fpm.d/www.conf
user = apache
group = apache
Change them to
user = nginx
group = nginx
Once changed, need to reload php-fpm
systemctl reload php-fpm
Test your PHP, by creating a simple info.php file with a phinfo() in it. The file should be placed in the directory root for your web server, which is /usr/share/nginx/html/info.php
.
To create the file use:
echo "<?php phpinfo() ?>" > /usr/share/nginx/html/info.php
Restart the Nginx and PHP-FPM.
systemctl restart nginx php-fpm
Now again, access http://localhost/info.php or http://yourserver-ip-address/info.php. You should see a page similar to below one.
