Step-by-Step cPanel Installation and Optimization Guide

Introduction to cPanel Installation

cPanel is one of the most popular control panels for web hosting management. In this article, we will explore how to install cPanel on AlmaLinux and optimize it step by step. By making the necessary settings to enhance server performance, we will improve the user experience.

Step 1: Update AlmaLinux

First, let's update our AlmaLinux server:

sudo dnf update -y

Step 2: Preparing for cPanel Installation

Before installing cPanel, let's install the required dependencies:

sudo dnf install perl -y

Now, navigate to the directory to start the cPanel installation:

cd /home

Step 3: Initiating cPanel Installation

To install cPanel, run the following command:

curl -o latest -L https://securedownloads.cpanel.net/latest && sh latest

The installation process may take some time. Once completed, enter your IP address in the browser to access the cPanel interface.

Step 4: cPanel Optimization

After installation, we need to make some optimization settings to enhance performance. First, let's open the Apache configuration file:

nano /etc/httpd/conf/httpd.conf

Check and optimize the following lines as needed:

KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 5

Step 5: PHP and MySQL Optimization

Let's edit the MySQL configuration file:

nano /etc/my.cnf

Add the following parameters to optimize:

[mysqld]
innodb_buffer_pool_size=1G
max_connections=200

Step 6: DDoS Protection and Security Settings

To protect against DDoS attacks, use iptables to regulate incoming traffic:

sudo iptables -A INPUT -p tcp --dport 80 -m state --state NEW,RELATED,ESTABLISHED -j ACCEPT
sudo iptables -A INPUT -p tcp --dport 443 -m state --state NEW,RELATED,ESTABLISHED -j ACCEPT

Step 7: SSL Certificate Installation

To install an SSL certificate, let's use Let's Encrypt to obtain a certificate:

sudo dnf install certbot -y
sudo certbot --apache

Conclusion

By following these steps, you have successfully installed and optimized cPanel on AlmaLinux. Implementing these settings is crucial for a high-performance server experience.
