Step-by-Step Server Optimization: cPanel Installation on AlmaLinux

Introduction

Server optimization is crucial for businesses providing web hosting services. In this article, we will detail the step-by-step installation and optimization of cPanel on AlmaLinux. One of the most important factors for improving server performance is the correct configuration of files.

1. Problem Source: Low Performance

Many users report that their servers are running slowly. This issue typically arises from inadequate resource usage, misconfigurations, or unnecessary loads. First, check the current status of your server by using the following SSH commands to observe system resources:

• top - Displays real-time system resource usage.
• free -m - Checks memory usage.
• df -h - Checks disk space.

2. cPanel Installation on AlmaLinux

cPanel is one of the most popular control panels for web hosting. Follow the steps below to install cPanel on AlmaLinux:

Step 1: AlmaLinux Updates

First, ensure that your system is up to date:

sudo dnf update -y

Step 2: cPanel Installation Requirements

Before installing cPanel, ensure that your system meets the following requirements:

• CentOS, AlmaLinux, or CloudLinux operating system
• Minimum 1 GB RAM (2 GB recommended)
• Minimum 20 GB of free disk space

Step 3: Downloading and Installing cPanel

Use the following commands to download and install cPanel:

cd /home
curl -o latest -L https://securedownloads.cpanel.net/latest/install.sh
sh latest

This process will take a few minutes. Once the installation is complete, note the information needed to access the cPanel interface.

3. Configurations for Server Optimization

After installing cPanel, you should make some configurations to enhance your server's performance.

Step 1: Apache and PHP Optimization

To make Apache run faster, you should make some adjustments in the httpd.conf file:

sudo nano /etc/httpd/conf/httpd.conf

Add or modify the following lines:

KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 5

Step 2: MySQL Optimization

You can enhance MySQL performance by editing the configuration file:

sudo nano /etc/my.cnf

Add or modify the following lines:

innodb_buffer_pool_size=1G
query_cache_size=64M
max_connections=200

Step 3: LiteSpeed Installation (Optional)

You can use LiteSpeed as a faster alternative to Apache. To install LiteSpeed:

cd /usr/src
curl -O https://www.litespeedtech.com/packages/openlitespeed.tar.gz
tar -xvf openlitespeed.tar.gz
cd openlitespeed
sudo ./install.sh

4. Security and DDoS Protection

To enhance server security, you should take necessary precautions. By installing CSF (ConfigServer Security & Firewall), you can provide DDoS protection:

cd /usr/src
curl -O https://download.configserver.com/csf.tgz
tar -xzf csf.tgz
cd csf
sh install.sh

Conclusion

By following these steps, you can successfully install cPanel and optimize your server on AlmaLinux. Don't forget to continuously monitor and optimize for better performance. For enhanced performance, consider using high-performance servers and NVMe SSDs.
