php - 连接到 nginx+php-fpm docker 的上游时，connect() 失败（111：连接被拒绝）

问题描述

介绍

我想创建一个由 提供支持的站点，php-fpm并且nginx我docker希望在单独的容器上拥有php-fpm和。nginx为此，我按照本教程进行操作，但现在在localhost:8000. 我的浏览器显示 502 并且我/var/log/nginx/project_error.log的已满

[error] 7#7: *1 connect() failed (111: Connection refused) while connecting to upstream, client: 172.20.0.1, server: app, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "localhost:8000"

搜索的答案

我已经对该主题进行了一些搜索，并找到了以下线程：

但是，他们都没有解决我的问题。

文件

我创建了一个包含所有文件的 GitHub 存储库，因此任何人都可以简单地在那里查看它（我认为这比将所有文件都转储到这里要好）。为此，只需执行

git clone git@github.com:tzfrs/dockertest.git
mkdir -p citynavigator/public
touch citynavigator/public/index.php

除此之外，这里是代码

一般的

解决方案

这是因为 127.0.0.1 应该是您的 php 服务的名称而不是 localhost

所以改变

fastcgi_pass php-upstream;

到

fastcgi_pass php:9000;

或在使用的上游指令中类似。

php如果它在同一个网络中（显然是通过code-network） ，则可以从您的 nginx 访问
