mysql ndbcluster设置root用户和远程登录  
1.root用户不能登录  
\[root@ndbcluster2 ~\]\# mysql -uroot -p  
Enter password:   
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)  
\[root@ndbcluster2 ~\]\# mysql -uroot -p  
Enter password:   
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)  
  
设置--skip-grant-tables跳过授权表认证  
service mysqld stop  
在配置文件中添加--skip-grant-tables（/etc/my.cnf）  
service mysqld start  
另外开个SSH连接  
\[root@localhost ~\]\# mysql  
mysql>use mysql  
mysql>update user set password=password("123456") where user="root";  
mysql>flush privileges;  
mysql>exit  
去掉--skip-grant-tables重启mysql,root用户可以用设置的密码登录  
  
设置root用户远程登录  
GRANT ALL PRIVILEGES ON \*.\* TO root@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;   
执行报如下错误，ERROR 1820 (HY000): You must SET PASSWORD before executing this statement  
\[root@ndbcluster1 ~\]\# mysql -uroot -p  
Enter password:

执行SET PASSWORD修改成功

mysql>   
FLUSH PRIVILEGES;  
  
执行完成  
远程连接测试，mysql集群节点，发现一个节点可以连接，一个节点不能连接  
这个问题纠结很久   \--由于对mysql集群不熟悉  
原因上面的操作，没有在另外一个节点上执行导致的，mysql集群的用户认证是分开管理的，要两个节点都要执行  
所以后创建用户要两个节点都执行
