我使用 php docker container 作为基础带有标签:

php:5.6-apache

当我尝试重新启动容器内的 apache2 时，容器停止:

root@phalconapp:/var/www/html# service apache2 restart
Restarting web server: apache2Terminated
root@phaclonapp:/var/www/html#
me@myLocalComputer:

如何在不停止容器的情况下重启apache2？

在将更改放入 dockerfile 之前，我想尝试使用容器并对其进行自定义。我想安装一些扩展并让它们工作我需要重新启动 apache 以使更改生效。

这是通过以下方式的日志文件:

最佳答案

如果您使用 apache 作为主要服务来保持正在运行的容器，则不能重新启动它。仅仅因为您构建了图像并使用它设置了 CMD。

The main purpose of a CMD is to provide defaults for an executing container. These defaults can include an executable, or they can omit the executable, in which case you must specify an ENTRYPOINT instruction as well.

尝试在不重启服务的情况下重新加载:

/etc/init.d/apache2 reload
