mysql cluster统一用户权限

统一用户权限

使用mysql cluster由于存放用户信息的表user是指mysql库里面的，而且这些表是MyISAM存储引擎的。如果希望所有的sql节点都有统一的用户权限，可以把创建用户的脚本在每个sql节点都执行一下，这样比较麻烦。可以使用mysql cluster的一个新特性来完成这些操作。就是把mysql cluster的sql节点的用户权限表转换成NDB数据库引擎的表。


下面是在其中一个sql节点的操作

 

[root@vmhost02 local]# mysql -u root -ppassword

 这些是最另外一个节点操作的

[root@vmhost06 ~]# mysql -u user1 -ppassword

ERROR 1045 (28000): Access denied for user 'user1'@'localhost' (using password: YES)

[root@vmhost06 ~]# mysql -u user1 -ppassword -h 192.168.163.160

ERROR 1045 (28000): Access denied for user 'user1'@'192.168.163.160' (using password: YES)

下面是转换用户权限表的操作，就两步，简单吧！

至此，用户在两个sql几点都出现了。而且以后新添加到用户无论是在哪个节点执行的命令，用户都可以在其他节点登录。
