mariadb 实用功能1 kill user xxx
实用性
在运维工作中，经常会遇到需要kill 掉某个用户的时候，MySQL 没有直接Kill user 的功能，
但是mariadb 早就有这个功能了，这个真的太贴心了，实用价值极高。
2.赶紧干起来吧，狠敲命令看结果
MariaDB [(none)]> select version()
-> ;
+-----------------+
| version() |
+-----------------+
| 10.1.20-MariaDB |
+-----------------+
1 row in set (0.00 sec)
MariaDB [(none)]> show processlist;
+----+--------+--------------------+------+---------+------+-------+------------------+----------+
| Id | User | Host | db | Command | Time | State | Info | Progress |
+----+--------+--------------------+------+---------+------+-------+------------------+----------+
| 8 | root | localhost | NULL | Query | 0 | init | show processlist | 0.000 |

+----+--------+--------------------+------+---------+------+-------+------------------+----------+
2 rows in set (0.00 sec)
MariaDB [(none)]> kill user roidba;
