代理本地website步骤：
1.写入hosts，才能将请求发到本地：
sudo vi /etc/hosts
2.配置vhost ngnix xxxxx.conf：
server {
listen 80;
server_name xxx.xxx.com;
set $node_port 8081;
location ~* /{
proxy_http_version 1.1;
proxy_set_header Connection "";
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_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_pass http://127.0.0.1:$node_port$request_uri;
proxy_redirect off;
}
}
3.运行ngnix：
ngnix -s stop
ngnix
ps -ef|grep ngnix
