rdo默认安装的用户，使用su - user 无法切换到该用户下

1、切换cinder用户报"This account is currently not available."

su - cinder 
This account is currently not available.

2、查看cinder用户权限

cat /etc/passwd |grep cinder 
cinder:x:165:165:OpenStack Cinder Daemons:/var/lib/cinder:/sbin/nologin

权限为：/sbin/nologin

3、修改用户登录权限

usermod -s /bin/bash cinder

4、查看权限

cat /etc/passwd |grep cinder 
cinder:x:165:165:OpenStack Cinder Daemons:/var/lib/cinder:/bin/bash

5、此时就可以切换到cinder用户了

su - cinder 

6、再次禁止用户切换

usermod -s /sbin/nologin cinder
