hive本地mysql

一、安装mysql数据库

1.安装mysql

使用命令:yum install mysql mysql-server

2.设置mysql为开机启动

使用命令：chkconfig -add mysqld  添加mysql服务

使用命令：chkconfig msyqld on

3.启动mysql

service mysqld restart

4.修改本地mysql用户密码

GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost'IDENTIFIED BY '123';

注意：是localhost而不是127.0.0.1就可以的，hive是本地启动模式默认会使用msyql数据库的user表中host为localhost的root用户登录mysql数据库。

5.刷新用户权限

flush privileges;

6.最好重启mysql服务

service mysqld restart

二、安装配置hive

1.解压hive的tar包

tar -xzvf apache-hive-1.2.1-bin.tar.gz

2.配置hive

在hive的conf目录下默认是没有hive-site.xml，将hive-default.xml 复制一个出来

cp hive-default.xml hive-site.xml

 配置hive-site.xml文件内容如下：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?><!--
