在连接到Nginx + php-fpm docker的上游时，connect（）失败（111：连接被拒绝） [英] connect() failed (111: Connection refused) while connecting to upstream for nginx+php-fpm docker

问题描述

我想创建一个由 php-fpm ， nginx 和 docker ，我想拥有 php-fpm 和 nginx 在单独的容器上。为此，我遵循了本教程，但现在在 localhost：8000 下访问我的Web服务器时卡住了。我的浏览器显示502，而我的 /var/log/nginx/project_error.log 已满

I want to create a site that is powered by php-fpm, nginx and docker and I want to have php-fpm and nginx on separate containers. To do this, I followed this tutorial but am stuck now when accessing my web server under localhost:8000. My browser displays a 502 and my /var/log/nginx/project_error.log is full with

[错误] 7＃7：* 1连接到上游时，connect（）失败（111：连接被拒绝），客户端：172.20.0.1，服务器：app，请求： GET / HTTP / 1.1，上游： fastcgi：//127.0.0.1：9000，主机： localhost：8000

我已经在该主题中进行了一些搜索，找到了以下线程：

I already searched a bit for this topic and found these threads:

但是，它们都没有解决我的问题。

However, none of them solved my problems.

我创建了一个包含所有文件的GitHub存储库，因此任何人都可以在那里简单地对其进行检查（我认为这比将所有文件都转储到此处要好）。为此，只需做

I created a GitHub repository containing all files, so anyone can simply check it out there (I think it's better than having all files dumped in here). To do that, simply do

git clone [e-mail]：tzfrs / dockertest.git

mkdir -p citynavigator / public

touch citynavigator / public / index.php

除此之外，这是代码

推荐答案

这是造成127.0的原因。 0.1应该是您的php服务的名称，而不是localhost

This is cause the 127.0.0.1 should be the name of your php service not the localhost

因此更改

fastcgi_pass php-upstream;

至

fastcgi_pass php:9000;

或与所使用的上游指令类似。

Or similar in the used upstream directive.

php 如果您的nginx在同一网络中（可以通过代码网络进行访问），则可以从您的nginx到达

php is reachable from your nginx if its in the same network (which obvously is through code-network)
