nginx management configuration optimization
This article mainly introduces the optimization of nginx management configuration, which has certain reference value. Now I share it with everyone. Friends in need can refer to it
nginx optimization
Optimization ideas
Basic optimization
1. Adjust parameters to hide nginx software version number information
server_tokens off;
2. Change nginx service default user
user nginx nginx;
3. Optimize the number of worker processes of nginx service
worker_processes cpu*核数;
4. Optimize binding of different nginx processes to different CPUs
worker_cpu_affinit 0001 0010 0100 1000 0001 0010 0100 1000;
5. Optimize nginx time processing model
use epoll
6. Adjust the maximum number of connections in a single process
worker_connections 20480;
7. The maximum number of open files in the nginx work process
worker_rlimit_nofile 65535;
8. Enable efficient file transfer mode
sendfile on;
is used to enable Efficient file transfer mode, and setting the tcp_nopush and tcp_nodelay instructions to on at the same time can prevent network and disk I/O blocking and improve nginx work efficiency.
9. Optimize connection timeout
keepalive_timeout 0; //结束响应后立即断开tcp连接。
10. FastCGI optimization
11. Configure nginx gzip compression to achieve performance optimization
gzip on; gzip_min_length 1k; gzip_buffers 4 32k; gzip_comp_level 9; gzip_vary on;
12. Configure nginx expires cache to achieve performance Optimization
nginx expires 3650d;
13. nginx log related optimization and security
14. Restrict program and file access based on extensions.
dell all;allow all;
15. Anti-hotlinking
HTTP referer
System level optimization
1. System level optimization
echo 500000 > /proc/sys/net/core/somaxconn //设置最大连接数 echo 1 > /proc/sys/net/ipv4/tcp_tw_recycle //加快tcp回收 echo 1 > /proc/sys/net/ipv4/tcp_tw_reuse //空的tcp允许回收利用 echo 0 > /proc/sys/net/ipv4/tcp_syncookies //关闭洪水抵御
2. nginx&php-fpm optimization configuration
nginx Forward the request to php-fpm for processing. When nginx forwards many requests, the php-fpm process is not enough, and a child process will be generated.
However, generating child processes requires kernel scheduling, which is time-consuming.
If the website concurrency is relatively large, you can statically generate multiple sub-processes at one time and keep them in memory.
Modify phjp-fpm.conf
pm=static //让php-fpm进程始终保持，不需要动态生成pm.max_children=32 始终保持的子进程数量
3, php&mysql optimization
Kernel level: increase the number of connections, speed up tcp recycling
mysql level: increase the number of connections
php level: Use long connections to save the number of connections
Use memory cache (memcached) to reduce the pressure on mysql
Note
The memory cache is suitable for caching complex sql queries. Because php and memcached also need to establish tcp connections, simple sql queries do not require caching.
The above is the detailed content of nginx management configuration optimization. For more information, please follow other related articles on the PHP Chinese website!
