【未解决】阿里云中二级域名转发中如何实现端口转发
期间，用加上nginx配置：
server
{
listen 80;
server_name
dev.xxx;
access_log /www/wwwlogs/
dev.xxx.log;
proxy_set_header HOST $host;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_Header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
location /storybook/
{
# proxy_redirect off;
# proxy_pass
http://xxx:33800;
proxy_pass
http://xxx:33800/;
}
}结果重启nginx出错：

出错了，去找找原因
之前VSCode中，对于配置文件第10行就白色，不正常：
现在去通过：
[root@xxx nginx]# journalctl -xe Nov 19 15:55:24 xxx nginx[4260]: Reload service nginx... nginx: [emerg] unknown directive "proxy_set_Header" in /www/server/panel/vhost/nginx/ dev.xxx.conf:10 Nov 19 15:55:24 xxx nginx[4260]: done Nov 19 15:55:24 xxx systemd[1]: Reloaded LSB: starts the nginx web server. -- Subject: Unit nginx.service has finished reloading its configuration -- Defined-By: systemd -- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel -- -- Unit nginx.service has finished reloading its configuration -- -- The result is done.

看到错误原因是：
Stoping nginx… nginx: [emerg] unknown directive “proxy_set_Header” in /www/server/panel/vhost/nginx/dev.xxx.conf:10
才注意到是拷贝别人的配置，语法错误，写成大写H了：
proxy_set_Header X-Real-IP $remote_addr;
应该改为：
proxy_set_header X-Real-IP $remote_addr;
【总结】
此处不小心把配置中：
proxy_set_header X-Real-IP $remote_addr;
（从别人代码拷贝过来的）误写为：
proxy_set_Header X-Real-IP $remote_addr;
所以报错。改正后，即可解决问题。
