我想创建一个由php-fpm，nginx和docker驱动的站点，并且我想在单独的容器上放置php-fpm和nginx。为此，我遵循了this tutorial，但是现在在访问localhost:8000下的Web服务器时陷入困境。我的浏览器显示502，而我的/var/log/nginx/project_error.log充满
[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"
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。
我created a GitHub repository包含所有文件，因此任何人都可以在那里简单地将其检出（我认为这比将所有文件转储到此处更好）。为此，只需做
git clone git@github.com:tzfrs/dockertest.git
mkdir -p citynavigator/public
touch citynavigator/public/index.php
除此之外，这是代码

答案 0 :(得分：1)
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;
或与所使用的上游指令中的类似。
如果您的nginx在同一网络中（很明显是通过代码网络），则可以从您的nginx访问 php
