Step by Step Hosting Server Optimization: cPanel Installation on AlmaLinux

Introduction

Optimizing hosting servers plays a critical role in enhancing performance. In this article, we will provide a step-by-step guide for installing and optimizing cPanel on AlmaLinux. We will make the necessary adjustments to improve server performance and ease management.

1. cPanel Installation on AlmaLinux

First, connect to your server via SSH:

ssh root@your_server_ip

Then, install the necessary packages for cPanel:

yum install perl

Download the cPanel installation script:

wget -N http://httpupdate.cpanel.net/latest

Start the installation:

sh latest

Once the installation is complete, access cPanel from your web browser at https://your_server_ip:2087.

2. cPanel Optimization

After completing the cPanel installation, you should make some adjustments for server optimization. First, we will optimize Apache and MySQL.

Apache Optimization

To edit the Apache configuration file:

nano /etc/httpd/conf/httpd.conf

Update the following parameters:

MaxRequestWorkers 150
KeepAlive On
KeepAliveTimeout 5
Timeout 30

Save the changes and restart Apache:

systemctl restart httpd

MySQL Optimization

To make changes to the MySQL configuration file:

nano /etc/my.cnf

Add or update the following parameters:

[mysqld]
innodb_buffer_pool_size = 1G
max_connections = 200
table_open_cache = 400

Restart the MySQL service:

systemctl restart mysql

3. DDoS Protection and Security

To protect against DDoS attacks, we will install CSF (ConfigServer Security & Firewall).

cd /usr/src
wget http://www.configserver.com/free/csf.tgz
 tar -xzf csf.tgz
 cd csf
 sh install.sh

After completing the CSF installation, edit the configuration file:

nano /etc/csf/csf.conf

Make the necessary adjustments and start CSF:

csf -r

4. SSL Certificate Installation

To install an SSL certificate, we will use Let’s Encrypt. First, install the Certbot tool from EFF:

yum install epel-release
yum install certbot

To obtain the SSL certificate:

certbot --apache -d your_domain.com -d www.your_domain.com

After completing the SSL certificate installation, add a cron job for automatic renewal:

crontab -e
0 0 * * * /usr/bin/certbot renew --quiet

Conclusion

By following these steps for cPanel installation and optimization on AlmaLinux, you can significantly enhance the performance of your hosting infrastructure. Remember that regular updates and security measures are essential for maintaining the health of your server.
