docker：当尝试连接到发布的端口时，拒绝连接 [英] docker: Says connection refused when attempting to connect to a published port

问题描述

我是码头工人的新手。我正在创建一个你好，世界的例子。所有我想要做的是在Docker中打开Apache，然后从主机中查看默认网站。

Dockerfile

  FROM centos：最新
 
运行yum安装epel-release -y 
 
运行yum安装wget -y 
 
运行yum安装httpd -y 
 
 EXPOSE 80 
 
 ENTRYPOINT [/ usr / sbin / httpd，-D，FOREGROUND ] 
  

然后我建立它：
> docker build。

然后我标记：

docker标签17283f566320我的：apache

然后我运行它：

 > docker run -p 80：9191 my：apache 
 AH00558：httpd：使用172.17.0.2无法可靠地确定服务器的完全限定域名。设置全局的ServerName指令以抑制此消息
  

然后运行....

在另一个终端窗口中，我尝试发出 curl 命令查看默认网站。

 >卷曲-XGET http ://0.0.0.0:9191 
 curl：（7）无法连接到0.0.0.0端口9191：连接拒绝
 
> curl -XGET http：// localhost：9191 
 curl：（7）无法连接到本地端口9191：拒绝连接
 
>卷曲-XGET http://127.0.0.1:9191 
 curl：（7）无法连接到127.0.0.1端口9191：拒绝连接
  

或者我尝试localhost

只是为了确保我的端口正确，我运行这个：

 > docker ps -l 
 CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 
 5aed4063b1f6 my：apachep/ usr / sbin / httpd -DF43 seconds ago Up 42 seconds 80 / tcp，0.0.0.0:80- > 9191 / tcp angry_hodgkin 
  

解决方案

我的端口被撤销：

 >码头运行-p 9191：80我的：apache 
  

I'm a newbie at docker. I'm creating a Hello, World example. All I'm trying to do is bring up Apache in a docker and then view the default website from the host machine.

Dockerfile

FROM centos:latest

RUN yum install epel-release -y

RUN yum install wget -y

RUN yum install httpd -y

EXPOSE 80

ENTRYPOINT ["/usr/sbin/httpd", "-D", "FOREGROUND"]

And then I build it: > docker build .

And then I tag it:

docker tag 17283f566320 my:apache

And then I run it:

> docker run -p 80:9191 my:apache
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 172.17.0.2. Set the 'ServerName' directive globally to suppress this message

It then runs....

In another terminal window, I attempt to issue the curl command to view the default web site.

> curl -XGET http://0.0.0.0:9191
curl: (7) Failed to connect to 0.0.0.0 port 9191: Connection refused

> curl -XGET http://localhost:9191
curl: (7) Failed to connect to localhost port 9191: Connection refused

> curl -XGET http://127.0.0.1:9191
curl: (7) Failed to connect to 127.0.0.1 port 9191: Connection refused

or I try localhost

Just to make sure that I got the port correct, I run this:

> docker ps -l
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                          NAMES
5aed4063b1f6        my:apachep      "/usr/sbin/httpd -D F"   43 seconds ago      Up 42 seconds       80/tcp, 0.0.0.0:80->9191/tcp   angry_hodgkin

解决方案

Thanks to all. My ports were reversed:

> docker run -p 9191:80 my:apache
