nginx针对请求的uri来代理

场景：1台nginx去代理4台apache 需求：根据不同的请求uri 代理到不同的apache

nginx的配置文件内容为：

upstream aa.com { server 192.168.0.121; server 192.168.0.122; } upstream bb.com { server 192.168.0.123; server 192.168.0.124; } server { listen       80; server_name  www.abc.com; location ~ aa.php { proxy_pass http://aa.com/; proxy_set_header Host   $host; proxy_set_header X-Real-IP      $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } location ~ bb.php { proxy_pass http://bb.com/; proxy_set_header Host   $host; proxy_set_header X-Real-IP      $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } }
