1、配置MYSQL
mysql> alter user 'root'@'localhost' identified by 'Yang3135989009';
Query OK, 0 rows affected (0.00 sec)mysql> grant all on *.* to 'root'@'%';
Query OK, 0 rows affected (0.00 sec)mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)
2、配置Hadoop
（1）进入Hadoop用户
hadoop@node1:/export/server/hadoop/etc/hadoop$ vim core-site.xml
（2）修改文件如下
给予Hadoop用户权限
</property><property><name>hadoop.proxyuser.hadoop.hosts</name><value>*</value></property> <property> <name>hadoop.proxyuser.hadoop.groups</name><value>*</value></property>
3、下载解压Hive
需要注意，此处应该切换到Hadoop用户
[hive下载链接]http://archive.apache.org/dist/hive/hive-3.1.3/apache-hive-3.1.3-bin.tar.gz
# 解压到node1服务器的：/export/server/内
tar -zxvf apache-hive-3.1.3-bin.tar.gz -C /export/server/
# 设置软连接
ln -s /export/server/apache-hive-3.1.3-bin /export/server/hive
4、下载MySQL驱动
需要注意，此处应该将用户切换为Hadoop。
[MySQL的驱动包]:https://repo1.maven.org/maven2/mysql/mysql-connector-java/5.1.34/mysql-connector-java-5.1.34.jar
# 将下载好的驱动jar包，放入：Hive安装文件夹的lib目录内
mv mysql-connector-java-5.1.34-sources.jar /export/server/hive/lib/
5、配置Hive
（1）修改hive-env.sh名称并配置path
目录：
hadoop@node1:/export/server/hive/conf$ pwd
/export/server/hive/conf改名：
hadoop@node1:/export/server/hive/conf$ mv hive-env.sh.template hive-env.sh配置：
export HADOOP_HOME=/export/server/hadoop
export HIVE_CONF_DIR=/export/server/hive/conf
export HIVE_AUX_JARS_PATH=/export/server/hive/lib
（2）创建hive-site.xml
<configuration><property><name>javax.jdo.option.ConnectionURL</name><value>jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true&useSSL=false&useUnicode=true&characterEncoding=UTF-8</value></property><property><name>javax.jdo.option.ConnectionDriverName</name><value>com.mysql.jdbc.Driver</value></property><property><name>javax.jdo.option.ConnectionUserName</name><value>root</value></property><property><name>javax.jdo.option.ConnectionPassword</name><value>密码</value></property><property><name>hive.server2.thrift.bind.host</name><value>node1</value></property><property><name>hive.metastore.uris</name><value>thrift://node1:9083</value></property><property><name>hive.metastore.event.db.notification.api.auth</name><value>false</value></property></configuration>
6、初始化元数据库
（1）配置hive在MySQL中的元数据库
CREATE DATABASE hive CHARSET UTF8;（2）初始化元数据库
# 进入hive路径
cd /export/server/hive
# 初始化MySQL元数据库
bin/schematool -initSchema -dbType mysql -verbos（3）验证
如果初始化成功，那么再次进入MySQL，我们可以在MySQL的hive库中看见274张新建的元数据的表。

7、给予权限和创建logs文件夹
（1）划分文件夹用户组和用户
在前面，使用的root用户，但是启动集群时，需要使用到Hadoop用户，所以这里我们需要将/export/server/路径下的hive 和apache-hive-3.1.3-bin的用户和用户组划给Hadoop，以便我们后序的使用。
root@node1:/export/server# chown -R hadoop:hadoop apache-hive-3.1.3-bin hive
root@node1:/export/server# ll
total 20
drwxr-xr-x 5 hadoop hadoop 4096 12月 23 13:17 ./
drwxr-xr-x 3 hadoop hadoop 4096 11月 4 14:16 ../
drwxr-xr-x 10 hadoop hadoop 4096 12月 23 13:03 apache-hive-3.1.3-bin/
lrwxrwxrwx 1 hadoop hadoop 27 11月 6 20:14 hadoop -> /export/server/hadoop-3.3.6/
drwxr-xr-x 11 hadoop hadoop 4096 11月 6 20:47 hadoop-3.3.6/
lrwxrwxrwx 1 hadoop hadoop 36 12月 23 13:17 hive -> /export/server/apache-hive-3.1.3-bin/
lrwxrwxrwx 1 hadoop hadoop 27 11月 4 14:25 jdk -> /export/server/jdk1.8.0_391/
drwxr-xr-x 8 hadoop hadoop 4096 11月 4 14:23 jdk1.8.0_391/（2）创建logs文件夹
切换到Hadoop用户创建logs文件夹
root@node1:/export/server# su - hadoop
hadoop@node1:~$ cd
hadoop@node1:~$ cd /export/server
hadoop@node1:/export/server$ cd hive
hadoop@node1:/export/server/hive$ ll
total 88
drwxr-xr-x 10 hadoop hadoop 4096 12月 23 13:03 ./

8、启动
1、后台启动元数据管理服务
hadoop@node1:/export/server/hive$ nohup bin/hive --service metastore >> logs/metastore.log 2>&1 &
[1] 66238
hadoop@node1:/export/server/hive$ cd logs
hadoop@node1:/export/server/hive/logs$ ll
total 12
drwxrwxr-x 2 hadoop hadoop 4096 12月 23 14:05 ./
drwxr-xr-x 11 hadoop hadoop 4096 12月 23 14:03 ../
-rw-rw-r-- 1 hadoop hadoop 1096 12月 23 14:06 metastore.log2、启动客户端
注意，需要提前开启hsfs和yarn集群。
cd /export/server/hive在该目录下有bin文件夹，bin中有hive启动程序，输入：
bin/hivehadoop@node1:/export/server/hive$ jps
71265 NodeManager
82227 Jps
71107 ResourceManager
69746 NameNode
69956 DataNode
71622 WebAppProxyServer
70271 SecondaryNameNode
66238 RunJar
【错误解决方案】：这里，很有可能出现报错，解决方案如下：
hdfs dfsadmin -safemode forceExit在开启hive之后，会出现如下：
hive> show databases;
OK
default
Time taken: 1.23 seconds, Fetched: 1 row(s)
hive>
