LAMP is an acronym of Linux, Apache, MySQL, and PHP. It is a free and open-source stack used by developers and website administrators to test and host their Web applications. It comes up with 4 components which are Apache (used for hosting a website), MySQL or MariaDB, and PHP – a popular scripting language used to create dynamic web pages. MariaDB or MYSQL are used to store and manage the data.
In this tutorial, we will learn how to install a LAMP Server on CentOS 8. So, let’s get started.
CentOS LAMP Installation
Before installation, keep your Systems Packages repository updated. For this, open up the terminal and use the following command:
# sudo dnf update
Installing Apache Web Server on CentOS8
After updating the system packages, the next step is to install the Apache Web Server and its tools, for this run the following command:
# sudo dnf install –y httpd httpd-tools
Once the installation is completed, enable and start the Apache service by running the following command:
# systemctl start httpd # systemctl enable httpd
To verify the service is running, run the following command:
# systemctl status httpd
As you can see that see Apache web service is running.
Configure CentOS Firewall
After installing Apache, update the firewall rules to allow requests for this use the following command:
# sudo firewall-cmd –add-service=http/tcp –permanent # sudo firewall-cmd –add-service-https/tcp –permanent # sudo firewall-cmd –reload
Additionally, you can open up a web browser and test your Web Services by typing IP address or localhost as shown below.
Now we have the Web server installed and running.
Installing MariaDB on CentOS 8
The next step is to install the Maria DB to store data and manage data for the website, for this use the following command:
# sudo dnf install –y mariadb-server mariadb
Once the installation is completed, enable and start the Maria DB service by running the following command:
# systemctl enable mariadb # systemctl start mariadb
To verify the service is running, use the following command:
# systemctl status mariadb
As you can see above that MariaDB is running.
To improve the security of the database, it’s recommended to run a security script that comes up with the MariaDB. It will remove the insecure default settings and lock the access of your database. To secure MariaDB by running the following command:
# mysql_secure_installation
It will prompt you to enter the root password or set it up, therefore, answer “Y” for every subsequent prompt.
Installing PHP on CentOS 8
The last component in the LAMP stack is PHP, I already mentioned that PHP is used to create a dynamic web page, to install PHP using the following command:
# sudo dnf install –y php php-mysqlnd
Testing the PHP
To test the PHP create a page under /var/www/html/ directory (default directory). Insert the code as shown below:
<?php phpinfo (); // it will print the PHP Information that we have installed ?>
Need to instruct SELinux to execute PHP code, for this use the following command:
# setsebool –P httpd_execmem 1
Finally restart the httpd service.
# systemctl restart httpd
Now open the web browser and type the IP address of your server on the search bar. You will get the output like shown below:
http://<ip-address>/info.php
We have PHP version 7.2.11 is installed and we can see PHP complete information on the web page.
Conclusion
In this tutorial, we learned how to set up LAMP Server with its component Apache, MariaDB, and PHP on CentOS 8. We also see how to handle PHP requests. I hope this tutorial will help you to set up a LAMP Server.
