systemctl 显示无法获得 D-Bus 连接：操作不允许

Question

操作系统：CentOS Linux release 7.5.1804 (Core)，物理机非docker，非虚拟机

我先用 升级 clickhouse yum localinstall ./clickhouse-*.rpm，然后我后悔了，我用 降级 clickhouse yum downgrade clickhouse-xx-xx.rpm，然后我发现systemctl status clickhouse-serverthrow

# systemctl status clickhouse-server
Failed to get D-Bus connection: Operation not permitted

并且

[root@cu75 ~]# systemctl
Failed to get D-Bus connection: Operation not permitted
[root@cu75 ~]# systemctl start dbus
Failed to get D-Bus connection: Operation not permitted
[root@cu75 ~]#

但 dbus 正在运行

[root@cu75 ~]# ps -ef | grep dbus

我在这个网站上检查了所有类似的问题，但大多数都是docker镜像，有什么解决方案可以解决吗？
