1. 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 |

| 12 | roidba | 192.168.1.92:56950 | NULL | Sleep   |   17 |       | NULL             |    0.000 |

+----+--------+--------------------+------+---------+------+-------+------------------+----------+

2 rows in set (0.00 sec)

MariaDB [(none)]> kill user roidba;

Query OK, 1 row affected (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 |

+----+------+-----------+------+---------+------+-------+------------------+----------+

1 row in set (0.00 sec)

MariaDB [(none)]>

如果我们要去选择一款数据库，那么我们一定要对选择的数据库有深入的了解和测试。搞技术最

反感的就是只动嘴，不动手的人！！

每天敲敲更快乐！
