Enhancing Server Performance with cPanel: Step-by-Step Guide

Introduction

cPanel is a popular control panel for web hosting services. However, you may encounter performance issues while using cPanel. In this article, we will provide step-by-step solutions to enhance the performance of a server running cPanel.

Source of Performance Issues

cPanel hosts many resource-intensive processes. In particular, MySQL queries, PHP processes, and Apache configurations often cause issues on high-traffic websites. Therefore, optimization is crucial.

Step 1: Connect to Server via SSH

First, connect to your server via SSH:

ssh root@server_ip_address

Step 2: MySQL Optimization

Optimizing the MySQL database is essential for improving performance. Follow these steps:

Edit my.cnf File

Open the MySQL configuration file:

nano /etc/my.cnf

Add or modify the following parameters:

[mysqld]
innodb_buffer_pool_size = 1G
max_connections = 200
query_cache_size = 64M

Save the changes and restart the MySQL service:

systemctl restart mysql

Step 3: Apache Optimization

To optimize the Apache server, follow these steps:

Edit httpd.conf File

Open the Apache configuration file:

nano /etc/httpd/conf/httpd.conf

Add the following parameters:

KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 5

Save the changes and restart the Apache service:

systemctl restart httpd

Step 4: Install LiteSpeed

Using LiteSpeed instead of Apache can enhance performance. To install LiteSpeed, use the following commands:

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

After configuring LiteSpeed, start the service:

/usr/local/lsws/bin/lswsctrl start

Step 5: Adding DDoS Protection

To protect against DDoS attacks, follow these steps:

iptables -A INPUT -p tcp --dport 80 -m limit --limit 25/minute --limit-burst 100 -j ACCEPT
iptables -A INPUT -p tcp --dport 80 -j DROP

Conclusion

By following the steps above, you can significantly enhance the performance of your server running cPanel. Each step will help you utilize your system resources more efficiently.
