NGINX+PHP-FPM 502 504 Questions

502,504 errors often occur

Ideas:

• Increase the size and number of cache files when Nginx communicates with PHP-FPM
• 5 PHP-FPM processes are statically bound, reducing the overhead of the frequency start process
• Using sock files instead of TCP port communication

Workaround:

The parameters for adjusting Nginx and PHP-FPM are as follows

# nginx.conf location段unix:/usr/local/php/var/run/php-fpm.sock# fastcgi.conf 修改内容fastcgi_buffers 32 128k;fastcgi_buffer_size 128k;fastcgi_busy_buffers_size 256k;fastcgi_temp_file_write_size 256k;

#php-fpm.conflisten = /usr/local/php/var/run/php-fpm.sock#提醒:别忘给php-fpm.sock加读写权限pm = static # 静态绑定5个进程pm.max_children = 5
