GBase 8a用sudo安装时出现输入密码等待300秒超时

问题描述：

We trust you have received the usual lecture from the local System Administrator. It usually boils down to these three things: #1) Respect the privacy of others. #2) Think before you type. #3) With great power comes great responsibility.

解决方案：
sudo用户默认策略是第一次执行命令时，要输入当前sudo用户的密码，如上就是要输入gbase操作系统用户的密码。 一旦运行成功，后续sudo则不再需要输入了。调整sudo用户的策略，明确不需要输入密码 NOPASSWD。

[root@gbase_rh7_001 ~]# cat /etc/sudoers.d/gbase
gbase ALL=(ALL) NOPASSWD:ALL
[root@gbase_rh7_001 ~]#
