NGINX學習筆記——Choosing an Outgoing IP Address

原文標題：Choosing an Outgoing IP Address

如果你的Proxy 伺服器有多個網路介面，有時候你可能會需要選擇特定的源IP地址串連被Proxy 伺服器或者上遊伺服器。如果NGINX後面的一個被Proxy 伺服器設定為只接受特定IP網路或者IP位址範圍的串連，這種配置就能派上用場了。
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 useful if a proxied server behind NGINX is configured to accept connections from particular IP networks or IP address ranges.

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

location /app1/ {    proxy_bind 127.0.0.1;    proxy_pass http://example.com/app1/;}

location /app2/ {    proxy_bind 127.0.0.2;    proxy_pass http://example.com/app2/;}

IP地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地址。
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:

location /app3/ {    proxy_bind$server_addr;    proxy_pass http://example.com/app3/;}

').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i <= lines; i++) { $numbering.append($('

').text(i)); }; $numbering.fadeIn(1700); }); });
