为了方便操作Hive的服务端和客户端均安装在master节点上

上传并解压
1 #创建Hive目录 2 [root@master ~]# mkdir /opt/SoftWare/Hive 3 #进入到Hive目录 4 [root@master ~]# cd /opt/SoftWare/Hive 5 #通过xshell工具上传至master主机 6 [root@master Hive]# rz 7 #解压 8 [root@master Hive]# tar ‐zxvf apache‐hive‐2.3.2‐bin.tar.gz 9 #修改文件夹的名字 10 [root@master Hive]# mv apache‐hive‐2.3.2‐bin hive‐2.3.2
配置环境变量
1 #打开配置文件 2 [root@master Hive]# vi /etc/profile 3 #在后面追加以下内容 4 export HIVE_HOME=/opt/SoftWare/Hive/hive‐2.3.2 5 export PATH=$PATH:$HIVE_HOME/bin 6 #使设置生效 7 [root@master Hive]# source /etc/profile
修改配置文件hive-site.xml
该文件不存在，需要复制hive-default.xml.template来创建
1 #进入到hive‐2.3.2目录 2 [root@master Hive]# cd hive‐2.3.2/ 3 #创建hive‐site.xml文件 4 [root@master hive‐2.3.2]# cp conf/hive‐default.xml.template conf/hive‐site.xml 5 [root@master hive‐2.3.2]# vi conf/hive‐site.xml 6 #创建指定目录 7 [root@master hive‐2.3.2]# hadoop fs ‐mkdir ‐p /hive/tmp 8 [root@master hive‐2.3.2]# hadoop fs ‐mkdir ‐p /hive/logs 9 [root@master hive‐2.3.2]# hadoop fs ‐mkdir ‐p /hive/warehouse
修改配置如下：
1 <property><!‐‐数据库连接地址，使用MySQL存储元数据信息‐‐> 2 <name>javax.jdo.option.ConnectionURL</name> 3 <value>jdbc:mysql://master:3306/metastore? 4 createDatabaseIfNotExist=true&useSSL=false</value> 5 </property> 6 <property><!‐‐数据库驱动‐‐> 7 <name>javax.jdo.option.ConnectionDriverName</name> 8 <value>com.mysql.jdbc.Driver</value> 9 </property> 10 <property><!‐‐数据库用户名‐‐> 11 <name>javax.jdo.option.ConnectionUserName</name> 12 <value>root</value> 13 <description>Username to use against metastore database</description> 14 </property> 15 <property><!‐‐密码‐‐> 16 <name>javax.jdo.option.ConnectionPassword</name> 17 <value>123456</value> 18 <description>password to use against metastore database</description> 19 </property> 20 <property><!‐‐HDFS路径，用于存储不同 map/reduce 阶段的执行计划和这些阶段的中间输出结 21 果。‐‐> 22 <name>hive.exec.local.scratchdir</name> 23 <value>/hive/tmp</value> 24 </property> 25 <property><!‐‐Hive 查询日志所在的目录，如果该值为空，将不创建查询日志。‐‐> 26 <name>hive.querylog.location</name> 27 <value>/hive/logs</value> 28 </property> 29 <property><!‐‐本地表的默认位置‐‐> 30 <name>hive.metastore.warehouse.dir</name> 31 <value>/hive/warehouse</value> 32 </property> 33 <property> 34 <name>hive.metastore.uris</name><!‐‐Hive连接到该URI请求远程元存储的元数据‐‐> 35 <value>thrift://master:9083</value> 36 </property> 37 <property><!‐‐关闭本地模式，此项不存在，需要自己添加‐‐> 38 <name>hive.metastore.local</name> 39 <value>false</value> 40 </property> 41 <property> 42 <name>hive.server2.logging.operation.log.location</name> 43 <value>/hive/logs</value> 44 </property> 45 <property> 46 <name>hive.downloaded.resources.dir</name> 47 <value>/hive/tmp/${hive.session.id}_resources</value> 48 </property>
修改配置文件
1 [root@master hive‐2.3.2]# vi bin/hive‐config.sh 2 #添加以下内容 3 export JAVA_HOME=/opt/SoftWare/Java/jdk1.8.0_152 4 export HADOOP_HOME=/opt/SoftWare/Hadoop/hadoop‐2.7.5 5 export HIVE_HOME=/opt/SoftWare/Hive/hive‐2.3.2
复制MySQL的驱动jar到hive/lib目录
1 [root@master hive‐2.3.2]# cd lib 2 [root@master lib]# rz
对Hive进行初始化并启动Hive

至此，Hive大仓库安装配置完成。
