Server Configurations for High Traffic Linux Hosting

The Logic of Optimization

High-traffic websites require special server configurations to effectively use system resources and enhance performance. In this article, we will examine the necessary adjustments for Linux-based servers step by step.

1. Basic Server Settings

First, we need to make some basic adjustments in the /etc/sysctl.conf file.

• net.core.somaxconn = 1024 - Increases the connection queue size.
• net.ipv4.tcp_max_syn_backlog = 2048 - Increases the SYN backlog size.
• net.ipv4.tcp_fin_timeout = 15 - Reduces the TCP connection shutdown time.

To save these settings, run the following command:

2. Web Server Configuration (Nginx / Apache)

If you are using Nginx, open the /etc/nginx/nginx.conf file and add the following configuration:

worker_processes auto;
worker_connections 1024;

For Apache, edit the /etc/httpd/conf/httpd.conf file:

MaxRequestWorkers 150
ServerLimit 150

3. LiteSpeed and MySQL Settings

If you are using LiteSpeed, you can enhance performance by increasing the Max Connections value in the lsws/conf/httpd_config.conf file. For example:

For MySQL, edit the /etc/my.cnf file:

• innodb_buffer_pool_size = 1G - Optimizes memory management.
• max_connections = 200 - Increases the number of users that can connect simultaneously.

4. DDoS Protection and Security

Cybersecurity is critical for high-traffic sites. You can add a simple DDoS protection rule using iptables:

5. SSL Certificate and HTTPS

To add an SSL certificate, you can use certbot for an automatic setup:

This command will automatically configure SSL settings with Nginx.

Conclusion

These adjustments are critical for enhancing performance and ensuring security for high-traffic websites. By following the steps above, you can increase your server's efficiency and provide a better user experience.
