Nginx转发指定路径到指定端口

关键代码如下：

http {

    upstream php_server {
        server 192.168.1.10:8080;
    }

    upstream java_server {
        server 192.168.1.10:8081;
    }

    upstream asp_server {
        server 192.168.1.20:8082;
    }


    server {
        listen       80;
        server_name  localhost;

    location ^~ /java/ {
        proxy_pass http://java_server/;
        proxy_set_header host $host;
        proxy_set_header X-forwarded-for $proxy_add_x_forwarded_for;
        proxy_set_header X-real-ip $remote_addr;
        }

    location ^~ /asp/ {
        proxy_pass http://asp_server/;
        proxy_set_header host $host;
        proxy_set_header X-forwarded-for $proxy_add_x_forwarded_for;
        proxy_set_header X-real-ip $remote_addr;
        }


    location / {
            proxy_pass http://php_server;
            proxy_set_header host $host;
        proxy_set_header X-forwarded-for $proxy_add_x_forwarded_for;
        proxy_set_header X-real-ip $remote_addr;
        }
}
