docker yum安装报错 服务启动报错

在使用docker容器yum安装时出现类似的错误：

Transaction check error:

这是由于从systemd-容器*包实际systemd的过渡。出于某种原因，上游包不过时或发生冲突，所以你会在安装包时出错。 解决办法是获取最新的centos镜像。或者执行命令：

yum install -y   libsystemd-daemon.so.0    libsystemd-id128.so.0  libsystemd-journal.so.0 libsystemd-login.so.0 libudev.so.1  systemd-container-libs

只能是祝你好运。

另外就是docker容器里面启动服务时出现：

Failed to get D-Bus connection: Operation not permitted

首先恭喜你使用centos7镜像，然后就是不幸告诉你这个问题是个BUG 将在centos7.2解决。

目前能做的就是使用其他的方式启动。或者看我的另一篇微博：http://welcomeweb.blog.51cto.com/10487763/1735251

Currently, systemd in CentOS 7 has been removed and replaced with a fakesystemd package for dependency resolution. This is due to systemd requiring the CAP_SYS_ADMIN capability, as well as being able to read the host's cgroups. If you wish to replace the fakesystemd package and use systemd normally, please follow the steps below.
