1. 准备
1.1 apache-hive-2.1.0-bin.tar.gz包
1.2 mysql中创建新的数据库hive
2. 解压
3. 修改环境变量
vim /etc/profile
export HIVE_HOME=xxxx
export PATH=$PATH:$HIVE_HOME/bin
然后刷新配置source /etc/profile
4. 修改配置文件
首先需要下载并把mysql-connector-java-5.1.17.jar拷贝到hive/lib目录下,作为驱动要用到。
配置文件都在hive/conf目录下
4.1 hive-site.xml
更名：mv hive-default.xml.template hive-site.xml
然后搜索关键字，把下面这部分做修改
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://192.168.27.166:3306/hive?createDatabaseIfNotExist=true</value>
</property>
<property>
<name>javax.jdo.option.ConnectionDriverName</name>
<value>com.mysql.jdbc.Driver</value>
</property>
<property>
<name>javax.jdo.option.ConnectionUserName</name>
<value>hive</value>
</property>
<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>hive</value>
</property>
<property>
<name>hive.metastore.warehouse.dir</name>
<value>/user/hive/warehouse</value>
</property>
然后把全文中的${system:java.io.tmpdir} 替换成/home/fantj/hive/fantj
${system:user.name}替换成 root
最后，创建该目录 mkdir -p /home/fantj/hive/fantj/root
4.2 hive-env.sh
更名：mv hive-env.sh.template hive-env.sh
添加环境参数：
export JAVA_HOME=/soft/jdk
export HIVE_HOME=/soft/hive
export HADOOP_HOME=/soft/hadoop
5. 创建数据库表到mysql里面
schematool -initSchema -dbType mysql
[root@s166 conf]# schematool -initSchema -dbType mysql

运行成功后查看hive数据库：
6. 测试hive环境
注意：注意hadoop要启动
6.1 输入hive命令
[root@s166 bin]# hive
