- Operating System CentOS 8
- Access as root or sudo user
Step 1 — Install Nginx
nginx package with:
$ sudo dnf install nginx
After the installation is finished, run the following command to enable and start the server:
$ sudo systemctl start nginx
firewalld is active, you’ll need to run the following command to allow external access on port
$ sudo firewall-cmd –permanent –add-service=http
Reload the firewall configuration so the changes take effect:
$ sudo firewall-cmd –reload
With the new firewall rule added, you can test if the server is up and running by accessing your server’s public IP address or domain name from your web browser. You’ll see a page like this:
Step 2 — Install MariaDB
We’ll now install MariaDB, a community-developed fork of the original MySQL server by Oracle.
To install this software, run:
$ sudo dnf install mariadb-server
When the installation is finished, enable and start the MariaDB server with:
$ sudo systemctl start mariadb
To improve the security of your database server, it’s recommended that you run a security script that comes pre-installed with MariaDB. Start the interactive script with:
$ sudo mysql_secure_installation
The first prompt will ask you to enter the current database root password. Because you just installed MariaDB and haven’t made any configuration changes yet, this password will be blank, so just press
ENTER at the prompt.
The next prompt asks you whether you’d like to set up a database root password. Because MariaDB uses a special authentication method for the root user that is typically safer than using a password, you don’t need to set this now. Type
N and then press
From there, you can press
Y and then
ENTER to accept the defaults for all the subsequent questions.
When you’re finished, log in to the MariaDB console by typing:
$ sudo mysql
This will connect to the MariaDB server as the administrative database user root, which is inferred by the use of
sudo when running this command. You should see output like this:
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 9
Server version: 10.3.17-MariaDB MariaDB Server
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type ‘help;’ or ‘\h’ for help. Type ‘\c’ to clear the current input statement.
To create a new database, run the following command from your MariaDB console:
MariaDB [(none)]> CREATE DATABASE test_database;
Now you can create a new user and grant them full privileges on the custom database you’ve just created:
MariaDB [(none)]> GRANT ALL ON test_database.* TO ‘test_user’@’localhost’ IDENTIFIED BY ‘password’ WITH GRANT OPTION;
Flush the privileges to ensure that they are saved and available in the current session:
MariaDB [(none)]> FLUSH PRIVILEGES;
Following this, exit the MariaDB shell:
MariaDB [(none)]> exit
Step 3 — Install PHP-FPM
To install the
php-mysql packages, run:
$ sudo dnf install php-fpm php-mysqlnd
When the installation is finished, you’ll need to edit the
/etc/php-fpm.d/www.conf file in order to adjust a couple settings. We’ll install
nano to facilitate editing these files:
$ sudo dnf install nano
Now open the
/etc/php-fpm.d/www.conf configuration file using
nano or your editor of choice:
$ sudo nano /etc/php-fpm.d/www.conf
Look for the
group directives. If you are using
nano, you can hit
W to search for these terms inside the open file. Make sure to change both values from
; RPM: apache user chosen to provide access to the same directories as httpd
user = nginx
; RPM: Keep a group allowed to write in log dir.
group = nginx
Save and close the file when you’re done editing.
To enable and start the
php-fpm service, run:
$ sudo systemctl start php-fpm
Finally, restart the Nginx web server so that it loads the configuration files created by the
$ sudo systemctl restart nginx
Step 4 — Test PHP with Nginx
On CentOS 8, the default
php-fpm installation automatically creates configuration files that will allow your Nginx web server to handle
.php files in the default document root located at
/usr/share/nginx/html. You won’t need to make any changes to Nginx’s configuration in order for PHP to work correctly within your web server.
We’ll only need to modify the default owner and group on Nginx’s document root, so that you can create and modify files in that location using your regular non-root system user:
$ sudo chown -R tony.tony /usr/share/nginx/html/
Create a new PHP file called
info.php at the
$ nano /usr/share/nginx/html/info.php
The following PHP code will display information about the current PHP environment running on the server:
Copy this content to your
info.php file, and don’t forget to save it when you’re done.
Now we can test whether our web server can correctly display content generated by a PHP script. Go to your browser and access your server hostname or IP address, followed by
You’ll see a page similar to this:
