Nginx域名反代隐藏端口不加端口就无法连接的解决办法 The correct configuration of Nginx reverse proxy with your own domain #40

MFYDev · 2021-03-19T09:44:15Z

注意！问题已解决，Nginx正确配置请参考：#40 (comment)

Attention! The problem has been solved. Please refer to the correct Nginx configuration #40 (comment)

Env：Ubuntu 20.04 + Nginx

When try to use reverse proxy to hide the port, all settings can ensure normal operation, but the premise is that you need to access https://domain name:port,

Loading Sshwifty will be displayed when port is deleted in the url

反向代理域名+端口时，所有设置能保证正常运行，但前提是需要访问 https://域名:端口 ，

删除端口访问时将显示 Loading Sshwifty

此错误很奇怪，按理说平常nginx反代完域名+端口之后直接访问域名就可以，但实际上直接访问域名sshwifty连日志都不会输出。

Nginx 反代配置如下：

问题已解决，错误配置隐藏 Problem resolved, error configuration hidden

location / {
     proxy_pass http://域名:端口;
     proxy_set_header Host $host;
     proxy_set_header X-Real-IP $remote_addr;
     proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
     proxy_set_header X-Forwarded-Proto https;
}

location /sshwifty/socket {
     proxy_pass http://域名:端口;
     proxy_http_version 1.1;
     proxy_set_header Host $host;
     proxy_set_header X-Real-IP $remote_addr;
     proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
     proxy_set_header X-Forwarded-Proto https;
     proxy_set_header Upgrade $http_upgrade;
     proxy_set_header Connection $connection_upgrade;
}

Conf中设定HostName为空，TLS证书指定位置正确。

就是去掉端口就无法访问，请帮忙看一下到底是哪里有错误呢？非常感谢了！

试试看可不可以设置一个upstream，并在其中的server项上指定端口。参考 #10 (comment)

另外，如果你有前置的Nginx，建议让Nginx去处理TLS，让Sshwifty服务器只服务HTTP。

MFYDev · 2021-03-19T10:02:23Z

还是不可以，参考 #21 (comment) 中的这个配置，我对Nginx进行了如下配置:

当upstream中的server设置为127.0.0.1时，显示loading SSHWifty
设置为 域名 时，显示报错http error 400

MFYDev · 2021-03-19T10:05:24Z

是的，我一开始时没有在配置conf中加入TLS证书位置的，一般正常都是前置Nginx能自动处理好Https，

但是sshwifty不加入位置的话，同样也是域名访问只显示Loading SSHWifty，加了端口报错ERR_SSL_PROTOCOL_ERROR

附上我的conf设置，便于排查：

nirui · 2021-03-19T10:31:55Z

我想问一下你的Nginx是运行在Docker里的么？是否可以用docker logs <你运行Nginx的容器>看看访问时有没有报告什么错误？

另外如果你的Nginx和Sshwifty都在容器里，那么请注意：每个Docker容器里的IP地址都是不一样的，你需要在配置好docker network之后使用容器的名称（通过--name指定）作为DNS域名来进行连接。

MFYDev · 2021-03-19T10:34:35Z

没有，这两者都是通过宝塔面板安装的，没有一个运行在docker中，通过查询Nginx访问日志中的错误日志如下：

问题已解决，错误配置隐藏，正确配置请参考：#40 (comment)

nirui · 2021-03-19T10:56:12Z

如果我把你在上面所提供的nginx.conf简化成：

events{
    worker_connections 1024;
}

http {
    map $http_upgrade $connection_upgrade {
        default upgrade;
        '' close;
    }

    upstream sshwifty_backend {
        server 127.0.0.1:8182;
    }

    server {
        listen 80;
        server_name localhost;
    
        location / {
            proxy_pass http://sshwifty_backend;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto https;
        }

        location /sshwifty/socket {
            proxy_pass http://sshwifty_backend;
            proxy_http_version 1.1;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto https;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection $connection_upgrade;
        }
    }
}

然后执行一个干净的Nginx实例（用docker run --name nginx-test -v $(pwd)/nginx.conf.test:/etc/nginx/nginx.conf:ro --rm -it --network host nginx），那么访问是成功的：

$ curl -v localhost
*   Trying 127.0.0.1:80...
* TCP_NODELAY set
* Connected to localhost (127.0.0.1) port 80 (#0)
> GET / HTTP/1.1

> User-Agent: curl/7.68.0
> Accept: */*

* Mark bundle as not supporting multiuse

因此我猜测这个问题和Nginx的location配置大概没什么关系。不过我仍然需要一些时间来分析你给出的其他信息。

MFYDev · 2021-03-19T10:57:42Z

收到，非常感谢nirui的指导，我将使用您的纯净配置尝试在我的服务器上部署。非常感谢您愿意抽出时间给我提出帮助和解答，辛苦了！再次感谢！

MFYDev · 2021-03-19T11:12:33Z

经测试，当conf文件不输入TLS位置时，通过域名访问不论是否加端口都会无法访问。
使用SSL证书唯一能够访问成功的方法时conf文件输入路径的同时nginx开启ssl证书，同时访问+端口号，可这样就失去了反代隐藏端口号的作用。
我将尝试使用预编译二进制文件构建dockerfile试一下

nirui · 2021-03-19T11:23:53Z

我想梳理一下，你现在遇到的问题，是在同一台计算机上部署的Nginx无法反向代理这台计算机上的Sshwfty，是这样的么？

MFYDev · 2021-03-19T11:24:57Z

是的没错，环境是Ubuntu 20.04，准确的来说时Web服务器而非本地电脑，整体环境采用干净的宝塔安装的Nginx

nirui · 2021-03-19T12:11:43Z

抱歉，我没有宝塔，所以没办法在那方面帮到你。不过我建议你做如下尝试：

在非Docker部署的前提下，将Sshwifty设置为仅监听lo（即127.0.0.1，默认就是这样），关闭TLS，留空HostName。完成启动之后，用curl在部署的机器上试试是否能访问Sshwifty（curl -v http://localhost:<部署Sshwifty的端口>）。

如果上面一步测试失败了，可能是Sshwifty没有成功启动（可以通过ps确认一下），然后看看日志。

在确认Sshwifty能够在本地正常访问之后，参考我上面给出的简化设置来配置你的Nginx（启用TLS等等），记得确保upstream的设置是：

upstream sshwifty_backend {
    server 127.0.0.1:<部署Sshwifty的端口>;
}

应用Nginx的设置后，继续在部署Nginx的计算机上用curl -v <nginx.conf里的server_name>和curl -v https://<nginx.conf里的server_name>来测试Nginx是否在正常的反向代理Sshwifty（正常时的返回状态会是200 OK）。如果可以的话，再在一台远程计算上用curl -v <server_name>来进行测试。

按你的用例来说，upstream里的server确实应该仅仅是127.0.0.1:<部署Sshwifty的端口>，而不是域名或外部IP地址。

题外话：老实说，如果你主要是通过Docker来管理你服务器上所运行的服务，那么可以考虑一下Traefik，它会自动帮你配置好这些东西，也就不用这么折腾了。

MFYDev · 2021-03-19T12:16:54Z

好的，非常感谢nirui的仔细回答，Traefik后续我会学习一下~之前有听说过，您的建议我将马上尝试，半小时内反馈更新

MFYDev · 2021-03-19T12:42:51Z

备注：浏览器为 Chrome 最新版

nirui · 2021-03-19T12:44:12Z

一步一步来：先试试看在Sshwifty的设置里去掉：

  "TLSCertificateFile": "/hdd/websites/<domain>/fullchain.pem",
  "TLSCertificateKeyFile": "/hdd/websites/<domain>/privkey.pem"

然后重启Sshwifty。

MFYDev · 2021-03-19T12:47:55Z

天呐原来问题在这里！超级感谢倪nirui！

此时已经成功了！

最重要的点就在于upstream里的server即使用了域名也要使用127.0.0.1，这和我之前所有的网站反代设置都不一样，并且设置成这个之后删除掉conf里的tls证书位置即可！

太感谢nirui了！此时能够成功访问了！

nirui · 2021-03-19T12:52:48Z

是这样的：其实你如果注意proxy_pass http://sshwifty_backend;这条设置，会发现其实设置里指定的了http://协议。而Sshwifty如果运行在TLS模式下，用HTTP去访问时Sshwifty会报TLS握手失败。你上面去掉了Sshwifty的TLS设置，让Sshwifty运行在HTTP下，这样访问就正常了。
