How to Install Nginx, MySQL, PHP (LEMP) Stack on CentOS 8/RHEL8
A software stack is a set of software tools bundled together. LEMP stands for Linux, Nginx (pronounced engine X), MariaDB/MySQL and PHP, all of which are open source. It is the most common software stack that powers dynamic websites and web applications. Linux is the operating system; Nginx is the web server; MariaDB/MySQL is the database server and PHP is the server-side scripting language responsible for generating dynamic web pages.
Note If logging in as a user other than admin or root use
su command to gain root access.
1. Install Nginx
Step 1 : Install nginx using the command:
yum install nginx -y
Step 2: Start and enable nginx service
systemctl start nginx systemctl enable nginx
Step 3: Check the status of nginx
systemctl status nginx
Check Nginx version
Step 4: Accessing Nginx
If you are installing LEMP on your local RHEL 8/CentOS 8 computer, then type
localhost in the browser address bar.
If RHEL 8/CentOS 8 is running on a remote server, then enter the hostname or IP address
Note Before accesing Nginx in remote server need to add services http, https in the firewall.
firewall-cmd --permanent --zone=public --add-service=http firewall-cmd --permanent --zone=public --add-service=https systemctl reload firewalld
Finally, we need to make user
nginx as the owner of web directory. By default it’s owned by the root use
chown nginx:nginx /usr/share/nginx/html -R
2.Installing MariaDB server
Step 1 : Install MariaDB using the command:
yum install mariadb-server mariadb -y
Step 2: Start and enable MariaDB service
systemctl start mariadb systemctl enable mariadb
Step 3: Check the status of MariaDB
systemctl status mariadb
Step 4: Run the Security Script
Note Press Enter and create a new password for the mariadb. Press Enter for all other options
Step 5: Entering into MariaDB server
mysql -u root -p
To exit, run
Step 1 : Install PHP and related modules using the command:
yum install php php-mysqlnd php-fpm php-opcache php-gd php-xml php-mbstring -y
Step 2: Start and enable php-fpm service
systemctl start php-fpm systemctl enable php-fpm
Step 3: Check the status of php-fpm
systemctl status php-fpm
Step4: Change the Configuration file
By default, PHP-FPM runs as the
apache user. Since we are using Nginx web server, we need to change it
user = nginx group = nginx
Reload PHP-FPM for the changes to take effect.
systemctl reload php-fpm
Step 5: Testing PHP
Create a file in document root :
And paste the following code
<?php phpinfo(); ?>
Save and close the file. If you installed LEMP stack on a local RHEL 8/CentOS 8 server, type in
localhost/info.php in the browser address bar.
If RHEL 8/CentOS 8 is running on a remote server, then enter
server-ip-address/info.php in browser address bar. Replace
sever-ip-address with your actual IP address.
Trouble Shooting Errors
1. If the browser fails to display the PHP info but prompt you to download the info.php file, simply restart Nginx and PHP-FPM.
sudo systemctl restart nginx php-fpm
2. If problem during yum installation Like Could not resolve host:mirrorlist.centos.org;
This indicates that you either (a) don’t have a properly configured DNS server or (b) your network configuration isn’t correct.
Replace content in the configuration file /etc/resolv.conf with
You can also try other DNS hosts if you would rather, such as
18.104.22.168 or any of the OpenDNS hosts.
