安裝Hive
- 把apache-hive-3.1.2-bin.tar.gz上傳到linux的/opt/software目錄下
- 解壓apache-hive-3.1.2-bin.tar.gz到/opt/module/目錄下面
[user@hadoop102 software]$ tar -zxvf /opt/software/apache-hive-3.1.2-
bin.tar.gz -C /opt/module/
- 修改apache-hive-3.1.2-bin.tar.gz的名稱為hive
[user@hadoop102 software]$ mv /opt/module/apache-hive-3.1.2-bin/
/opt/module/hive
- 修改/etc/profile.d/my_env.sh,新增環境變數
[user@hadoop102 software]$ sudo vim /etc/profile.d/my_env.sh
- 新增內容
#HIVE_HOME
export HIVE_HOME=/opt/module/hive
export PATH=$PATH:$HIVE_HOME/bin
- 解決日誌Jar包衝突
[user@hadoop102 software]$ mv $HIVE_HOME/lib/log4j-slf4j-impl-2.10.0.jar $HIVE_HOME/lib/log4j-slf4j-impl-2.10.0.bak
- 初始化後設資料庫
[user@hadoop102 hive]$ bin/schematool -dbType derby -initSchema
安裝MySQL
- 檢查當前系統是否安裝過MySQL
[user@hadoop102 ~]$ rpm -qa|grep mariadb
mariadb-libs-5.5.56-2.el7.x86_64
//如果存在透過如下命令解除安裝
[user@hadoop102 ~]$ sudo rpm -e --nodeps mariadb-libs
- 將MySQL安裝包複製到/opt/software目錄下,並解壓到/opt/module/
[user@hadoop102 software]$ tar -xf mysql-5.7.28-1.el7.x86_64.rpm-bundle.tar -C /opt/module/
- 在/opt/module/目錄下執行rpm安裝,按照順序依次執行!

- 刪除/etc/my.cnf檔案中datadir指向的目錄下的所有內容,如果有內容的情況下
檢視datadir的值:
[mysqld]
datadir=/var/lib/mysql
刪除/var/lib/mysql 目錄下的所有內容:
[user@hadoop102 mysql]# cd /var/lib/mysql
[user@hadoop102 mysql]# sudo rm -rf ./* //注意執行命令的位置
- 初始化資料庫
[user@hadoop102 opt]$ sudo mysqld --initialize --user=mysql
- 檢視臨時生成的root使用者的密碼,root@localhost:密碼
[user@hadoop102 opt]$ sudo cat /var/log/mysqld.log
- 啟動MySQL服務
[user@hadoop102 opt]$ sudo systemctl start mysqld
- 登入MySQL資料庫
[user@hadoop102 opt]$ mysql -uroot -p
Enter password:

- 修改root使用者的密碼
mysql> set password = password("新密碼");
- 修改mysql庫下的user表中的root使用者允許任意ip連線
mysql> update mysql.user set host='%' where user='root';
mysql> flush privileges;
複製驅動
將MySQL的JDBC驅動複製到Hive的lib目錄下
[user@hadoop102 software]$ cp /opt/software/mysql-connector-java-5.1.37-bin.jar $HIVE_HOME/lib
配置Metastore到MySQL
- 在$HIVE_HOME/conf目錄下新建hive-site.xml檔案
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<!-- jdbc 連線的 URL -->
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://hadoop102:3306/metastore?useSSL=false</value>

<!-- 指定儲存後設資料要連線的地址 -->
<property>
<name>hive.metastore.uris</name>
<value>thrift://hadoop102:9083</value>

</property>
<!-- 指定 hiveserver2 連線的埠號 -->
<property>
<name>hive.server2.thrift.port</name>
<value>10000</value>
</property>
- 啟動hiveserver2
[user@hadoop102 hive]$ bin/hive --service hiveserver2
