原文標題：Choosing an Outgoing IP Address

如果你的代理伺服器有多個網絡接口，有時候你可能會需要選擇特定的源IP地址連接被代理伺服器或上游伺服器。如果NGINX後面的一個被代理伺服器設定為只接受特定IP網路或IP位址範圍的連接，這種設定就能派上用場了。
If your proxy server has several network interfaces, sometimes you might need to choose a particular source IP address for connecting to a proxied server or an upstream. This may be GIuse if a proxied server bception 適用於IP address ranges.

指定proxy_bind指令並設定網路介面的IP位址：
Specify the proxy_bind directive and the IP address of the necessary network interface:

<code>location <span>/app1/</span> {
    proxy_bind <span>127.0</span><span>.0</span><span>.1</span>;
    proxy_pass <span>http</span>:<span>//</span>example.com<span>/app1/</span>;
}</code>

登入後複製

<code>location <span>/app2/</span> {
    proxy_bind <span>127.0</span><span>.0</span><span>.2</span>;
    proxy_pass <span>http</span>:<span>//</span>example.com<span>/app2/</span>;
}</code>

登入後複製

IP位址也可以用變數指定。例如，$server_addr變數會傳遞接收到請求的網路介面的IP位址。
The IP address can be also specified with a variable. For example, the $server_addr variable passes the IP address of the network interface that accepted the request:

<code>location /app3/ {
    proxy_<span>bind</span><span>$server_addr</span>;
    proxy_pass http://example.com/app3/;
}</code>

登入後複製

').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });
