nginx配置問題

由于生產(chǎn)環(huán)境限制，只能對(duì)外開放一個(gè)端口9988，其他人寫的項(xiàng)目也要用這個(gè)端口，所以只能用不同的請(qǐng)求路徑來區(qū)分不同的項(xiàng)目。

我的項(xiàng)目是前后分離的。頁面打包的內(nèi)容放到服務(wù)器目錄是：/usr/local/m2m/nbMsg/browser/dist，java后臺(tái)的端口是：8989，且后臺(tái)接口統(tǒng)一前綴/api/v1。

我想配置成訪問http://[host]:9988/nbmsg，能夠默認(rèn)返回/usr/local/m2m/nbMsg/browser/dist目錄下的html靜態(tài)頁面文件，然后頁面上的ajax請(qǐng)求都是/api/v1開頭的，需要代理到8989端口。

下面是我的配置。一個(gè)server是原來已有的9988端口的虛擬主機(jī)，另一個(gè)8999端口的虛擬主機(jī)是我加上去的。我應(yīng)該如何修改配置？讓http://[host]:9988/nbmsg的請(qǐng)求都轉(zhuǎn)發(fā)到8999端口的虛擬主機(jī)上？

server {
    listen 9988;
    root /server/html;

    # Add index.php to the list if you are using PHP
    index index.html index.htm index.php index.nginx-debian.html;

    location / {
        index index.html index.htm index.php;
    #    try_files $uri $uri/ =404;
    }

    location /business/ {
        #    root /server/html;
        try_files $uri $uri/ /business/public/index.php?$query_string;
    }
