nginx 反向代理时丢失端口的解决方案(转)

# the 90 port
server {
listen 90;
server_name zxy1994.cn;
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-Server $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host:$server_port; #这里是重点,这样配置才不会丢失端口
location / {
proxy_pass http://127.0.0.1:9001;
}
location = /50x.html {
root html;
}
}
