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
