Step-by-Step cPanel Installation on AlmaLinux for Corporate Hosting

Introduction

Corporate hosting solutions are critical for securely hosting web projects of businesses. However, if not configured properly, server performance may degrade or security vulnerabilities may arise. In this article, we will perform the installation and optimization of cPanel on AlmaLinux step by step.

1. Problem Source

Common issues encountered during corporate hosting setup include:

• Incorrectly configured DNS settings
• Firewall rules
• Missing or invalid cPanel license
• Insufficient system resources

To resolve these issues, following the correct steps is essential.

2. cPanel Installation on AlmaLinux

Step 1: Preparing the Server

First, ensure that your AlmaLinux server is up to date. Use the following command to check for updates:

sudo dnf update -y

Step 2: Checking Requirements

Verify the required specifications for cPanel installation. cPanel requires at least 1 GB of RAM and 20 GB of disk space. You can check your current hardware resources with the following command:

free -m && df -h

Step 3: Installing cPanel

To install cPanel, run the following commands:

cd /home
wget -N http://httpupdate.cpanel.net/latest
sh latest

During installation, cPanel will automatically install all necessary dependencies.

Step 4: Firewall Settings

Make sure that the necessary ports are open for cPanel to function properly. You can open the required ports with the following command:

sudo firewall-cmd --add-port=2083/tcp --permanent
sudo firewall-cmd --add-port=2087/tcp --permanent
sudo firewall-cmd --reload

Step 5: Licensing cPanel

To use cPanel, you need to purchase a license. Visit the official cPanel website to obtain a license, and to activate it:

/usr/local/cpanel/cpkeyclt

Step 6: Accessing cPanel

After the installation is complete, you can access cPanel by entering https://IP_ADDRESS:2083 in your browser. On the first login, you will need to configure the settings of the management panel.

3. Performance and Security Optimization

After installation, you should make some adjustments to enhance the performance and security of your server:

• LiteSpeed Web Server: You can improve performance by using LiteSpeed instead of Apache. To install:

cd /usr/local/src
wget https://www.litespeedtech.com/packages/openlitespeed.tar.gz
tar -xvzf openlitespeed.tar.gz
cd openlitespeed
./install.sh

• Firewall and DDoS Protection: Enhance your security by installing CSF (ConfigServer Security & Firewall):

cd /usr/src
wget https://get.acme.sh
sh get.acme.sh

After installation, configure the necessary settings to implement DDoS protection and other security measures.

Conclusion

Installing cPanel on AlmaLinux is an important step for corporate hosting. By following the steps outlined above, you can make your server secure and high-performing. Remember to regularly perform updates and security checks to protect your system.
