前期博客
你可以按照我写的这篇博客去，按照hive的mysql。
1 复习ha相关 + weekend110的hive的元数据库mysql方式安装配置（完全正确配法）（CentOS版本）（包含卸载系统自带的MySQL）
出现如下问题
ERROR 1045 (28000): Access denied for user 'hive'@'localhost' (using password: YES)
ERROR 1045 (28000): Access denied for user 'hive'@'master' (using password: YES)
ERROR 1045 (28000): Access denied for user 'hive'@'%' (using password: YES)
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
ERROR 1045 (28000): Access denied for user 'root'@'master' (using password: YES)
ERROR 1045 (28000): Access denied for user 'root'@'%' (using password: YES)
ERROR 1045 (28000): Access denied for user 'root'@'127.0.0.1' (using password: YES)
最后要达到这个目的（才可以解决问题！！！）
进入root用户
mysql> select user,host,password from mysql.user;
mysql> select user,host,password from mysql.user;
+------+-----------+-------------------------------------------+
| user | host | password |
+------+-----------+-------------------------------------------+
| root | localhost | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B |
| root | master | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B |
| hive | localhost | *4DF1D66463C18D44E3B001A8FB1BBFBEA13E27FC |
| hive | master | *4DF1D66463C18D44E3B001A8FB1BBFBEA13E27FC |
| hive | % | *4DF1D66463C18D44E3B001A8FB1BBFBEA13E27FC |
| root | % | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B |
+------+-----------+-------------------------------------------+
关键是hive用户下的这三个配置出来就好， hive@% hive@master hive@localhost
我的这里，是root对各个主机下密码都是root。hive对各个主机密码都是hive。
或者
mysql> select user,host,password from mysql.user; +------+-----------+-------------------------------------------+ | user | host | password | +------+-----------+-------------------------------------------+ | root | localhost | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B | | root | djt11 | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B | | hive | localhost | *4DF1D66463C18D44E3B001A8FB1BBFBEA13E27FC | | hive | djt11 | *4DF1D66463C18D44E3B001A8FB1BBFBEA13E27FC | | hive | % | *4DF1D66463C18D44E3B001A8FB1BBFBEA13E27FC | | root | % | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B | +------+-----------+-------------------------------------------+ 6 rows in set (0.00 sec)
关键是hive用户下的这三个配置出来就好， hive@% hive@master hive@localhost
我的这里，是root对各个主机下密码都是root。hive对各个主机密码都是hive。
怎么来解决问题？
进入root用户，执行
[root@master native]# mysql -uroot -p
Enter password:（默认是回车）
MySQL> use mysql
