上傳並解壓
1 #創建Hive目錄 2 [root@master ~]# mkdir /opt/SoftWare/Hive 3 #進入到Hive目錄 4 [root@master ~]# cd /opt/SoftWare/Hive 5 #通過xshell工具上傳至master主機 6 [root@master Hive]# rz 7 #解壓 8 [root@master Hive]# tar ‐zxvf apache‐hive‐2.3.2‐bin.tar.gz 9 #修改文件夾的名字 10 [root@master Hive]# mv apache‐hive‐2.3.2‐bin hive‐2.3.2
配置環境變量
1 #打開配置文件 2 [root@master Hive]# vi /etc/profile 3 #在后面追加以下內容 4 export HIVE_HOME=/opt/SoftWare/Hive/hive‐2.3.2 5 export PATH=$PATH:$HIVE_HOME/bin 6 #使設置生效 7 [root@master Hive]# source /etc/profile
修改配置文件hive-site.xml
該文件不存在，需要復制hive-default.xml.template來創建
1 #進入到hive‐2.3.2目錄 2 [root@master Hive]# cd hive‐2.3.2/ 3 #創建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 #創建指定目錄 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：

修改配置文件
1 [root@master hive‐2.3.2]# vi bin/hive‐config.sh 2 #添加以下內容 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
復制MySQL的驅動jar到hive/lib目錄
1 [root@master hive‐2.3.2]# cd lib 2 [root@master lib]# rz
對Hive進行初始化並啟動Hive

至此，Hive大倉庫安裝配置完成。
