fastcgi-mono-server4和nginx与docker

问题描述 投票：2回答：1

网上有很多信息告诉我们如何在同一台机器上设置nginx + fastcgi-mono-server4来托管ASP.net（目前我正在使用带有Websharper的F＃应用程序）来自linux环境。但是docker应该只运行一个进程。还有解决方案，使用runit或其他工具在同一容器上运行nginx和mono服务器。

我让它在同一容器中工作，但是当我尝试将web应用程序+ fastcgi-mono-server4移动到另​​一个容器时，我得到了

 [error] 12#12: *1 connect() failed (111: Connection refused) while connecting to upstream, client: 192.168.99.1, server: , request: "GET / HTTP/1.1", upstream: "fastcgi://172.17.0.40:32775", host: "192.168.99.100:32786"

找到了一个关于类似要求的article，但是对于php fastcgi服务器（php-fpm），它只适用于链接容器。但对于fastcgi-mono-server4，它没有。

我尝试使用fastcgi-mono-server4 +应用程序文件创建1个容器，暴露一个VOLUME的应用程序文件，暴露端口9000然后nginx容器与第一个容器的卷并链接到它也试图运行2个相同的容器与nginx和单声道服务器安装，首先使用fastcgi_pass 127.0.0.1:9000，第二个使用fastcgi_pass 172.17.0.40:32775 - ip和第一个容器的端口。如果访问第一个容器 - 应用程序工作，访问第二个容器 - 与上面相同的错误。

用于运行mongo服务器的命令：

fastcgi-mono-server4 /printlog=True /applications=/:/var/www/websharper/ /socket=tcp:0.0.0.0:9000 /loglevels=All /verbose=True

已安装软件的版本：

在mono：4.0.0 docker image上安装：

apt-get install -y ca-certificates nginx=1.9.5-1~wheezy
apt-get install -qy mono-fastcgi-server4
apt-get install -qy mono-xsp4
apt-get install -qy fsharp

另外我确保mono 4.5用于应用程序：

sed -ie 's|mono/4.0|mono/4.5|g' /usr/bin/fastcgi-mono-server4 \
&& sed -ie 's|mono/4.0|mono/4.5|g' /usr/bin/xsp4

还有我的nginx.conf

worker_processes  1;
events {
   worker_connections  1024;
}
http {
   include       mime.types;
   default_type  application/octet-stream;
   sendfile        on;
   keepalive_timeout  65;
   server {
       listen       80 default;
       access_log   /dev/stdout;
       error_log    /dev/stdout;
       root         /var/www/websharper;
       index        main.html;
       location / {
           root                /var/www/websharper/;
           fastcgi_pass        172.17.0.40:32775;
           include             /etc/nginx/fastcgi_params;
       }
       error_page   500 502 503 504  /50x.html;
       location = /50x.html {
           root   html;
       }
   }
}

最后是fastcgi_params

fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;
fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;
fastcgi_param  HTTPS              $https if_not_empty;
fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;
fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;
fastcgi_param  PATH_INFO         "";
fastcgi_param  SCRIPT_FILENAME   $document_root$fastcgi_script_name;

更新：

我在源代码中发现TcpSocket正在分配Loopback ip，如果你选择Any ip ...这很奇怪......

class TcpSocket : StandardSocket {
    public TcpSocket (System.Net.IPEndPoint localEndPoint)
        : base (System.Net.Sockets.AddressFamily.InterNetwork, System.Net.Sockets.SocketType.Stream,
                System.Net.Sockets.ProtocolType.IP, localEndPoint)
    {
    }

    public TcpSocket (System.Net.IPAddress address, int port)
        : this (new System.Net.IPEndPoint (Equals(address, System.Net.IPAddress.Any) ?
            System.Net.IPAddress.Loopback : address, port))
    {
    }
}

无论如何，我试图直接使用set ip address for mono server（通过将nginx容器链接到mono容器）

fastcgi-mono-server4 /printlog=True /applications=/:/var/www/websharper/ /socket=tcp:$(printenv NGINX_HOST_PORT_80_TCP_ADDR):9000 /loglevels=All /verbose=True

和运行框

docker run --name t2 --link t1:nginx_host -it -P vasylpurchel/docker-websharper

其中t1是一个在其中运行nginx的框此测试也失败了：

地址172.17.0.5是运行nginx的容器的IpAddress。

nginx mono docker fastcgi fastcgi-mono-server

使用参数时，fastcgi-mono-server4对docker容器有一个限制，带有监听地址

  • / socket = tcp：9000只能在localhost中监听
  • /socket=tcp:0.0.0.0:9000只能在localhost中监听，很奇怪，但却是真的

要修复fastcgi-mono-server4行为，您必须在套接字参数中使用docker容器IP地址

  • /插座= TCP：IPContainer：9000
  • / socket = tcp：$（ip -4 addr show eth0 | grep -Po'inet \ K [\ d。] +'）：9000

你需要修复Docker容器内的命令

fastcgi-mono-server4 /applications=/:/var/www/websharper/ /socket=tcp:$(ip -4 addr show eth0| grep -Po 'inet \K[\d.]+'):9000

这是Dockerfile修复的一个例子

FROM mono:latest

RUN apt-get update
RUN apt-get install -y mono-fastcgi-server4
RUN rm -rf /var/lib/apt/lists/* /tmp/*

RUN echo "#!/bin/sh\nfastcgi-mono-server4 /applications=/:/var/www/websharper/ /socket=tcp:\$(ip -4 addr show eth0| grep -Po 'inet \K[\d.]+'):9000" > /opt/mono-fastcgi
RUN chmod +x /opt/mono-fastcgi

EXPOSE 9000

CMD [ "/opt/mono-fastcgi" ]
