类似的问题已被多次询问，我已经完成了大部分问题，但我仍然无法解决问题。
我在不同的docker容器中运行Apache2和PHP 7 FPM，但它们无法相互连接。 连接失败并出现以下错误。

注意：PHP-FPM正在侦听端口9000上的连接及其正常工作。当我尝试从我的主机操作系统（例如http://localhost/而不是http://localhost:8080访问它时，我能够连接并获得所需的输出。）
我还尝试设置www/html的权限，并尝试将www-data设为所有者。
有人可以帮我解决这个问题吗？
提前感谢您的帮助。
答案 0 :(得分：3)
在您的示例中，localhost或127.0.0.1是容器的本地（而不是主机）。因此，当Apache尝试在127.0.0.1:9000连接到FPM时，它实际上是在尝试连接到自身（仅限Apache容器）。
您要做的是让Apache连接到FPM容器。使用Docker网络执行此操作的最简单方法是使用Docker Compose中的服务名称。在您的情况下，服务名称为php，并且可以从Apache容器的DNS名称php获得。
因此，您的Apache配置应为：
SetHandler "proxy:fcgi://php:9000"

我也遇到了同样的错误，只是花了整整一天的时间才弄清楚原因。
在我的情况下，问题是在我的VPS中启用了IP v6，而没有将真正的IP6地址分配给我的接口。
我刚刚禁用了IPV6，一切又恢复了正常。 （如果未使用IPv6 / IPv4，则将其禁用）
第1步-在外壳程序中使用以下命令编辑sysctl.conf文件
vi /etc/sysctl.conf
第2步-添加以下两行以禁用IPv6
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
第3步-保存并关闭文件（Esc->：wq）
第4步-为立即生效，在shell中运行以下代码
sysctl -p
