一 使用ubuntu维护版本安装:

http://manpages.ubuntu.com/manpages/xenial/man8/sudo_root.8.html

ENEFITS OF USING SUDO

The benefits of leaving root disabled by default include the following:

       * Users  do  not  have  to  remember  an extra password, which they are
         likely to forget.

       * The installer is able to ask fewer questions.

       * It avoids the "I can do anything" interactive login by default -  you
         will  be  prompted  for  a  password before major changes can happen,
         which should make you think about the consequences of  what  you  are
         doing.

       * Sudo adds a log entry of the command(s) run (in /var/log/auth.log).

       * Every  attacker  trying  to  brute-force their way into your box will
         know it has an account named root and will try that first. What  they
         do not know is what the usernames of your other users are.

       * Allows  easy  transfer for admin rights, in a short term or long term
         period, by adding and removing users from the sudo group,  while  not
         compromising the root account.

       * sudo can be set up with a much more fine-grained security policy.

       * On systems with more than one administrator using sudo avoids sharing
         a password amongst them.

 

二 使用docker 自身维护版本安装
