使用nginx做反向代理的時候，可以簡單的直接把請求原封不動的轉發給下一個服務。設定proxy_pass請求只會替換域名，如果要根據不同的url字尾來訪問不同的服務，則需要通過如下方法：

方法一：

 1 server {
 2     listen              8000;
 3     server_name         abc.com;
 4     access_log  "pipe:rollback /data/log/nginx/access.log interval=1d baknum=7 maxsize=1G"  main;
 5 
 6     location ^~/user/ {
 
 7         proxy_set_header Host $host;
 8         proxy_set_header  X-Real-IP        $remote_addr;
 9         proxy_set_header  X-Forwarded-For  $proxy_add_x_forwarded_for;
10         proxy_set_header X-NginX-Proxy true;
11 
12         proxy_pass http://user/;
13     }
14 
15     location ^~/order/ {
16         proxy_set_header Host $host;
 
17         proxy_set_header  X-Real-IP        $remote_addr;
18         proxy_set_header  X-Forwarded-For  $proxy_add_x_forwarded_for;
19         proxy_set_header X-NginX-Proxy true;
20 
21         proxy_pass http://order/;
22     }
23 }

^~/user/表示匹配字首是user的請求，proxy_pass的結尾有/， 則會把/user/*後面的路徑直接拼接到後面，即移除user。

方法二：

upstream user {
  server localhost:8089 weight=5;
}
upstream order {
  server localhost:8090 weight=5;
}

server {
    listen              80;
    server_name  abc.com;
    access_log  "pipe:rollback /data/log/nginx/access.log interval=1d baknum=7 maxsize=1G"  main;

    location ^~/user/ {
        proxy_set_header Host $host;
        proxy_set_header  X-Real-IP        $remote_addr;
        proxy_set_header  X-Forwarded-For  $proxy_add_x_forwarded_for;
        proxy_set_header X-NginX-Proxy true;

        rewrite ^/user/(.*)$ /$1 break;
        proxy_pass http://user;
    }

    location ^~/order/ {
        proxy_set_header Host $host;
        proxy_set_header  X-Real-IP        $remote_addr;
        proxy_set_header  X-Forwarded-For  $proxy_add_x_forwarded_for;
        proxy_set_header X-NginX-Proxy true;

        rewrite ^/order/(.*)$ /$1 break;
        proxy_pass http://order;
    }
}

proxy_pass結尾沒有/，rewrite重寫了url。
