Server Optimization: Critical Error Solutions and Implementation Steps

The Logic of Server Optimization

Server optimization is a systematic process aimed at improving the performance of a server and making resource usage as efficient as possible. Servers may experience performance degradation under high traffic loads, negatively impacting user experience. This article will focus on critical error solutions related to server optimization.

Step-by-Step Server Optimization

1. Apache Web Server Optimization

To optimize the Apache web server, you need to edit the httpd.conf file.

• Enable KeepAlive: KeepAlive On
• Set KeepAlive timeout: KeepAliveTimeout 5
• Increase MaxKeepAliveRequests: MaxKeepAliveRequests 100

2. MySQL Database Optimization

To improve MySQL database performance, edit the my.cnf file:

• innodb_buffer_pool_size = 1G (70% of server RAM)
• max_connections = 200
• query_cache_size = 64M

3. Linux Kernel Settings

To optimize kernel settings, edit the /etc/sysctl.conf file:

• net.core.somaxconn = 1024
• vm.swappiness = 10
• fs.file-max = 100000

4. DDoS Protection and Security Settings

To protect against DDoS attacks, implement the following settings:

• iptables -A INPUT -p tcp --dport 80 -m connlimit --connlimit-above 100 -j REJECT
• iptables -A INPUT -p tcp --dport 443 -m connlimit --connlimit-above 100 -j REJECT

5. High-Performance SSD Usage

Using high-performance NVMe SSDs can boost your server speed. You can test disk I/O operations with the fio tool:

• fio --name=randwrite --ioengine=libaio --rw=randwrite --bs=4k --numjobs=16 --size=1G --runtime=60

Conclusion

The steps outlined above are crucial for ensuring server optimization and resolving performance issues. By correctly applying these settings, you can enhance your server's efficiency.
