High Performance Server Optimization: Critical Error Solutions

What is High Performance Server Optimization?

High performance servers play a critical role in enhancing business efficiency and improving user experience. However, the performance of these servers can decline over time. In this article, we will explore the optimization of high performance servers and how to resolve critical errors step by step.

The Logic of Optimization

Server optimization is a series of adjustments and configuration changes made to ensure more efficient use of system resources. This supports the harmonious operation of hardware and software components while enhancing the overall performance of the server.

Step 1: Evaluate Server Resources

First, assess the current resource usage of your server. You can use the following commands to check CPU and memory usage:

• CPU Usage: top or htop
• Memory Usage: free -m

Step 2: MySQL Optimization

To enhance MySQL database performance, you may need to edit the my.cnf file. Below are basic settings:

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

The above settings optimize MySQL's memory usage and allow for more concurrent connections.

Step 3: Web Server Optimization

Optimizing web servers like Apache or Nginx is also crucial. For example, you can adjust the httpd.conf file for Apache as follows:

KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 5

These settings enhance the processing speed of HTTP requests.

Step 4: Disk Performance

If you're using NVMe SSDs, review the settings in the fstab file to boost disk performance:

/dev/nvme0n1p1 / ext4 defaults,noatime,nodiratime 0 1

These settings reduce disk access times.

Step 5: Firewall and DDoS Protection

Check your firewall settings and enable DDoS protection systems. For example, you can set up basic configuration with iptables:

iptables -A INPUT -p tcp --dport 80 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j ACCEPT
iptables -A INPUT -j DROP

Conclusion

Optimizing high performance servers is an ongoing process. By following the steps outlined above, you can enhance your server's performance and prevent critical errors.
