HIVE使用mysql作为外置数据库配置详情

Hive安装配置（mysql)

---

安装mysql

hadoop$:sudo apt-get update

hadoop$:sudo apt-get install mysql-server

启动mysql

hadoop$:sudo service mysql start

进入mysql界面

hadoop$:sudo mysql -u root -p

创建hive数据库

mysql>create database hive;

将hive数据库下的所有表的所有权限赋给hadoop用户,并配置mysql为hive-site.xml中的连接密码，然后刷新系统权限关系表

mysql>CREATE USER 'hadoop'@'%' IDENTIFIED BY '123123';

mysql>GRANT ALL PRIVILEGES ON *.* TO 'hadoop'@'%' WITH GRANT OPTION;

mysql>flush privileges;

修改配置文件将地址绑定注释

hadoop$:sudo vi /etc/mysql/my.cnf

找到#bind-addreess =127.0.0.1 注释掉这行就可以了

解压缩hive

hadoop$:sudo tar -zxvf /home/bigdata/hive-2.1.tar.gz -C /opt/modules

设置hive的环境变量

hadoop$:vi /etc/profile

如下

export HIVE_HOME=/opt/modules/hive-0.12.0

export PATH=$HIVE_HOME/bin:$PATH

修改hive-site.xml,先要拷贝出一份hive-site.xml,默认是没有的

hadoop$:cp hive-site.xml.template hive-site.xml

hadoop$:vi hive-site.xml

<property>

<name>hive.metastore.local</name>

<value>false</value>

</property>

<property>

<name>javax.jdo.option.ConnectionURL</name>
