Step-by-Step Guide to Building a CentOS LAMP Server
Step 1: Update Your System
The first step is to ensure that your system is up to date. Open your terminal and type the following command:
sudo dnf update
This command will update your system to the latest updates and security patches.
Step 2: Install Apache
The next step is to install Apache, a popular open-source web server. To do this, type the following command in your terminal:
sudo dnf install httpd
This command will install Apache on your CentOS server.
Step 3: Start and Enable Apache
After installing Apache, you need to start and enable the Apache service. To do this, type the following command:
sudo systemctl start httpd
sudo systemctl enable httpd
The first command starts the Apache service, and the second one ensures that Apache starts automatically at boot time.
Step 4: Configure Firewall for Apache
You need to configure your firewall to allow HTTP and HTTPS traffic. To do this, type the following command:
sudo firewall-cmd --permanent --add-service=http
sudo firewall-cmd --permanent --add-service=https
sudo firewall-cmd --reload
The first two commands add HTTP and HTTPS services to your firewall’s permanent list, and the third command reloads the firewall configuration.
Step 5: Install MySQL
The next step is to install MySQL, an open-source relational database management system. To do this, type the following command:
sudo dnf install mysql-server
This command will install MySQL on your CentOS server.
Step 6: Start and Enable MySQL
After installing MySQL, you need to start and enable the MySQL service. To do this, type the following command:
sudo systemctl start mysqld
sudo systemctl enable mysqld
The first command starts the MySQL service, and the second one ensures that MySQL starts automatically at boot time.
Step 7: Secure MySQL Installation
You need to secure your MySQL installation by running a secure installation script. To do this, type the following command:
sudo mysql_secure_installation
This command will walk you through a series of prompts to secure your MySQL installation.
Step 8: Install PHP
The final step is to install PHP, a popular open-source server-side scripting language for web development. To do this, type the following command:
sudo dnf install php php-mysqlnd php-json php-fpm
This command will install PHP and its necessary extensions on your CentOS server.
