[root@localhost ~]#

四、远程管理

C:\Documents and Settings\Administrator>mysql -uuser_all -p -P1999 -h192.168.0.2

31

Enter password: ******

Welcome to the MySQL monitor. Commands end with ; or \g.

Your MySQL connection id is 3

Server version: 1.0-beta

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> show instances;

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

| instance_name | state |

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

| mysqld1 | online |

| mysqld2 | online |

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

2 rows in set (0.00 sec)

mysql> quit

总结：

MySQL数据库的实例管理器对于多个MySQL实例的管理是很方便的,但它本身存在两个不足：

1、不能直接进行数据库的SQL管理命令。

2、一定要确保IM进程不会突然挂掉。
