问题描述

在centos 7.4 container centos-cloudera-1 中部署mariadb，使用systemctl 启动mariadb提示如下：

[root@centos-cloudera-1 /]# systemctl start mariadb
Failed to get D-Bus connection: Operation not permitted

解决方法

1.新建container添加/usr/sbin/init以及privileged参数

[root@localhost ~]# docker run -ti --privileged --name centos-cloudera-5 --hostname centos-cloudera-5 514d36e6e77d /usr/sbin/init

2.在启动该container后，需要对其进行stop/start操作，如果不进行stop/start操作，就无法进入该container，不清楚具体元婴

[root@localhost ~]# docker stop centos-cloudera-5
centos-cloudera-5
[root@localhost ~]# docker start centos-cloudera-5
centos-cloudera-5

3.安装&启动mariadb-server

[root@centos-cloudera-5 /]#yum -y install mariadb-server
[root@centos-cloudera-5 /]# systemctl enable mariadb
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.
[root@centos-cloudera-5 /]# systemctl start mariadb
[root@centos-cloudera-5 /]# systemctl status mariadb
