MySQL Cluster 用户权限共享 (各sql节点同步)

转自：http://blog.csdn.net/ylqmf/article/details/7866517

MySQL Cluster API节点 中mysql.user 表为MyISAM引擎，所以每个API都要配置权限系统，MySQL已经为我们提供了共享权限脚本。这个脚本主要作用就是将mysql.user 表MyISAM引擎更换为NDBCLUSTER引擎。

以 linux - Centos 单机 源码 编译 安装 mysql cluster 7.2.7 source install 为例，执行下面的脚本可以实现共享权限。
