通过 Nginx 反向代理部署 Node.js 服务

<pre class="prettyprint <a href=" http:=" data-ke-src=" www.ahlinux.com="" perl="" "="" target="_blank" style="word-wrap: break-word; margin-top: 0px; margin-bottom: 0px; padding: 0px;">perl">server
{ listen
80;
server_name mangguo.org www.mangguo.org;
index
index.html
index.htm;
root /home/wwwroot/mangguo.org;
location / {
proxy_set_header X-Real-IP
$remote_addr;
proxy_set_header X-Forwarded-For
$proxy_add_x_forwarded_for;
proxy_set_header Host
$http_host;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://127.0.0.1:3000; proxy_redirect off;
}
access_log /home/wwwlogs/mangguo.org.log access;}

这样设置后，访客流量首先访问 Nginx 进程，而不是直接访问 Node.js 进程，因此，如果需要获取真实的访客 IP，可以通过以下方法：
<pre class="prettyprint <a href=" http:=" data-ke-src=" www.ahlinux.com="" java="" "="" target="_blank" style="word-wrap: break-word; margin-top: 0px; margin-bottom: 0px; padding: 0px;">javascript">
function

getClientIp
(req) { req.headers['x-forwarded-for']
|| req.connection.remoteAddress;}
