ERR_CONNECTION_RESET 使用本地主机时

Question

我是后端开发新手。我正在使用 vagrant 和 virtualbox 创建一个基本的网络服务器。运行从 VM 连接服务器后，当我尝试从主机访问它时，出现上述错误。

以下是 vagrant 配置：

Vagrant.configure(2) do |config|
  config.vm.box = "ubuntu/trusty32"
  config.vm.network "forwarded_port", guest: 80, host: 8080
end

服务器文件中的main()代码如下：

def main():
    try:
        port = 8080
        server = HTTPServer(('', port), webserverHandler)
        print "Web server running on port %s" % port
        server.serve_forever()  

    except KeyboardInterrupt:
        print "^C entered. Shutting down the server..."
        server.socket.close()

在阅读了很多有关它的资料后，我尝试了一些方法让它工作但无济于事。主机上的 telnet localhost 8080 也给出：

Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host.

运行 vagrant up 显示它正在将端口从 80（来宾）转发到 8080（主机）。但是 VM 上的运行ning sudo netstat -ntlp | grep LISTEN 给出：

tcp        0      0 0.0.0.0:111             0.0.0.0:*               LISTEN      491/rpcbind     
tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      685/sshd        
tcp        0      0 0.0.0.0:52166           0.0.0.0:*               LISTEN      649/rpc.statd   
tcp6       0      0 :::57101                :::*                    LISTEN      649/rpc.statd   
tcp6       0      0 :::111                  :::*                    LISTEN      491/rpcbind     
tcp6       0      0 :::22                   :::*                    LISTEN      685/sshd

运行 curl -v 'http://localhost:8080' 给出：

*   Trying 127.0.0.1...
* Connected to localhost (127.0.0.1) port 8080 (#0)
> GET / HTTP/1.1
> Host: localhost:8080
> User-Agent: curl/7.47.0
> Accept: */*
> 
* Recv failure: Connection reset by peer
* Closing connection 0
curl: (56) Recv failure: Connection reset by peer

运行 curl 'http://localhost:80' 在 VM 上给出：

curl: (7) couldn't connect to host

这是我运行vagrant up:

我对此完全陌生。让我知道我在这里做错了什么。

您的 python 服务器运行在端口 8080 上，运行端口 80 没有任何内容（如 netstat 命令的输出所示）

在您的情况下，您需要将来宾端口更改为来自您的 python 服务器

的端口

config.vm.network "forwarded_port", guest: 8080, host: 8080
