Important Note: CentOS 7 reached End of Life (EOL) on June 30, 2024, and is no longer supported by Red Hat. This means CentOS 7 may be vulnerable to security risks and unpatched vulnerabilities. It is strongly recommended to consider upgrading to a supported operating system to ensure continued security and support.

If you still wish to use CentOS 7, you need to import the old repository by running the following commands to access archived packages:

sed -i s/mirror.centos.org/vault.centos.org/g /etc/yum.repos.d/CentOS-*.repo

sed -i s/^#.baseurl=http/baseurl=http/g /etc/yum.repos.d/CentOS-*.repo

sed -i s/^mirrorlist=http/#mirrorlist=http/g /etc/yum.repos.d/CentOS-*.repo

sed -i s/mirror.centos.org/vault.centos.org/g /etc/yum.repos.d/CentOS-*.repo sed -i s/^#.baseurl=http/baseurl=http/g /etc/yum.repos.d/CentOS-*.repo sed -i s/^mirrorlist=http/#mirrorlist=http/g /etc/yum.repos.d/CentOS-*.repo

sed -i s/mirror.centos.org/vault.centos.org/g /etc/yum.repos.d/CentOS-*.repo
sed -i s/^#.baseurl=http/baseurl=http/g /etc/yum.repos.d/CentOS-*.repo
sed -i s/^mirrorlist=http/#mirrorlist=http/g /etc/yum.repos.d/CentOS-*.repo

Introduction

LAMP is a software stack consisting of Linux, Apache, MySQL (or MariaDB), and PHP, and is widely used for hosting websites and web applications. This combination of technologies allows the server to serve dynamic web content and interact with databases, making it essential for content management systems like WordPress and Joomla.

Here’s a breakdown of the LAMP stack components:

Linux: The operating system (e.g., Red Hat, CentOS, Rocky Linux).
Apache: The web server application.
MySQL/MariaDB: The relational database management system.
PHP: A server-side scripting language used for web development.

This guide walks through the steps of installing and configuring each of these components on CentOS 7.

Step 1: Install Apache

Install Apache by running the following command:
Plain text
Copy to clipboard
Open code in new window
EnlighterJS 3 Syntax Highlighter
yum install httpd
yum install httpd
```
yum install httpd
```
Start the Apache service:
Plain text
Copy to clipboard
Open code in new window
EnlighterJS 3 Syntax Highlighter
systemctl start httpd.service
systemctl start httpd.service
```
systemctl start httpd.service
```
Disable the firewall for simplicity (not recommended in production environments):
Plain text
Copy to clipboard
Open code in new window
EnlighterJS 3 Syntax Highlighter
systemctl stop firewalld.service
systemctl stop firewalld.service
```
systemctl stop firewalld.service
```
Open your browser and enter your server’s IP address. If Apache is running, you should see the default Apache test page.
Enable Apache to start at boot:
Plain text
Copy to clipboard
Open code in new window
EnlighterJS 3 Syntax Highlighter
systemctl enable httpd.service
systemctl enable httpd.service
```
systemctl enable httpd.service
```

Step 2: Install MariaDB

Install MariaDB (used in place of MySQL on CentOS 7):
Plain text
Copy to clipboard
Open code in new window
EnlighterJS 3 Syntax Highlighter
yum install mariadb-server mariadb
yum install mariadb-server mariadb
```
yum install mariadb-server mariadb
```
Start and enable MariaDB at boot:
Plain text
Copy to clipboard
Open code in new window
EnlighterJS 3 Syntax Highlighter
systemctl start mariadb.service
systemctl enable mariadb.service
systemctl start mariadb.service systemctl enable mariadb.service
```
systemctl start mariadb.service 
systemctl enable mariadb.service
```
Secure MariaDB installation:
Plain text
Copy to clipboard
Open code in new window
EnlighterJS 3 Syntax Highlighter
mysql_secure_installation
mysql_secure_installation
```
mysql_secure_installation
```

Since we just installed MariaDB there shouldn’t be a root password, press enter then select if you want to add in a password for MariaDB root account. After that, simply enter “y” for the rest of the prompts.

Access MariaDB as root:
Plain text
Copy to clipboard
Open code in new window
EnlighterJS 3 Syntax Highlighter
mysql -u root -p
mysql -u root -p
```
mysql -u root -p
```
Enter the root password (if applicable) to proceed. Type exit to log out.

Step 3: Install PHP

Install PHP and its MySQL extension:
Plain text
Copy to clipboard
Open code in new window
EnlighterJS 3 Syntax Highlighter
yum install php php-mysql
yum install php php-mysql
```
yum install php php-mysql
```
Restart Apache to load PHP:
Plain text
Copy to clipboard
Open code in new window
EnlighterJS 3 Syntax Highlighter
systemctl restart httpd.service
systemctl restart httpd.service
```
systemctl restart httpd.service
```
Create a PHP info file to verify PHP installation:
Plain text
Copy to clipboard
Open code in new window
EnlighterJS 3 Syntax Highlighter
vi /var/www/html/info.php
vi /var/www/html/info.php
```
vi /var/www/html/info.php
```
Add the following:

Plain text
Copy to clipboard
Open code in new window
EnlighterJS 3 Syntax Highlighter
<?php
phpinfo();
?>
<?php phpinfo(); ?>
```
<?php 
phpinfo(); 
?>
```
Open your browser and navigate to
<your-server-ip>/info.php

to confirm PHP installation.

Conclusion

By following these steps, you have successfully installed the LAMP stack (Linux, Apache, MariaDB, PHP) on CentOS 7. This setup allows you to host dynamic websites and manage databases on your server. Given CentOS 7’s EOL status, consider migrating to a supported version for long-term security and stability.
