Docker CentOS 映像不会自动启动 httpd [英] Docker CentOS image does not auto start httpd

问题描述

我正在尝试使用 Apache 和 PHP 程序运行一个简单的 Docker 映像.如果我运行它会正常工作

I'm trying to run a simple Docker image with Apache and a PHP program. It works fine if I run

docker run -t -i -p 80:80 my/httpd /bin/bash

然后手动启动Apache

then manually start Apache

service httpd start

但是我不能让 httpd 在运行时自动启动

however I cant get httpd to start automatically when running

docker run -d -p 80:80 my/httpd

Apache 将启动，然后容器存在.我在我的 docker 文件中尝试了一堆不同的 CMDs

Apache will startup then container exists. I have tried a bunch of different CMDs in my docker file

CMD /etc/init.d/httpd start
CMD ["service" "httpd" "start"]
CMD ["/bin/bash", "/etc/init.d/httpd start"]
ENTRYPOINT /etc/init.d/httpd CMD start
CMD ./start.sh

start.sh 是

#!/bin/bash
/etc/init.d/httpd start

但是每次 docker 实例在 apache 启动后都会存在

However every-time docker instance will exist after apache starts

我是否遗漏了一些非常明显的东西?

Am I missing something really obvious?

推荐答案

你需要直接运行 apache (httpd) - 你不应该使用 init.d 脚本.

You need to run apache (httpd) directly - you should not use init.d script.

两种选择:

1. 您必须在前台运行 apache:/usr/sbin/apache2 -DFOREGROUND ...(或 CentOS 中的/usr/sbin/httpd)
2. 您必须通过执行 /sbin/init 作为入口点来启动所有服务(包括配置为自动运行的 apache).

1. you have to run apache in foreground: /usr/sbin/apache2 -DFOREGROUND ... (or /usr/sbin/httpd in CentOS)
2. you have to start all services (including apache configured as auto-run) by executing /sbin/init as entrypoint.
