例如PHP負載平衡不需要反向代理，直接fastcgi_pass到多個php-fpm也可以做負載平衡。

具體配置：

upstream myapp { server 192.168.20.1:9000; # PHP-FPM 1 server 192.168.20.2:9000; # PHP-FPM 2 ...... } server { listen 80; location ~ \.php$ { include fastcgi_params; fastcgi_param SCRIPT_FILENAME /phpfiles$fastcgi_script_name; fastcgi_pass myapp; } }
