hive下載安裝與配置

一、準備工作

安裝hive的前提是已經在主機中安裝好JDK、hadoop、mysql如果準備還沒有安裝這樣三個，可以參考如下文章安裝

JDK:https://blog.csdn.net/qq_42668255/article/details/97368887

hadoop:https://blog.csdn.net/qq_42668255/article/details/91385098

mysql:https://blog.csdn.net/qq_42668255/article/details/93979412

二、下載

提取碼:avej

三、安裝

1. 解壓：tar -zxvf apache-hive-2.2.0-bin.tar.gz
2. 移動：mv apache-hive-2.2.0-bin.tar.gz   /home/ubuntu/hive2.2.0  (此目錄爲自己想要將hive放置的目錄,後面目錄路徑都以此爲例)
3. 配置環境變量：vim /etc/profile
4. 輸入命令立即生效： source /etc/profile
5. 進入hive的conf目錄  cd /home/ubuntu/hive2.2.0/conf
   1. cp hive-default.xml.template hive-site.xml
   2. cp hive-env.sh.template hive-env.sh
   3. cp hive-log4j2.properties.template hive-log4j2.properties
   4. cp hive-exec-log4j2.properties.template hive-exec-log4j2.properties
6. 開啓hadoop服務器：start-all.sh
7. 創建HDFS目錄：

   1. hadoop fs -mkdir -p /user/hive/warehouse

   2. hadoop fs -mkdir -p /user/hive/tmp 

   3. hadoop fs -mkdir -p /user/hive/log 

   4. hadoop fs -chmod -R 777 /user/hive/warehouse 

   5. hadoop fs -chmod -R 777 /user/hive/tmp 

   6. hadoop fs -chmod -R 777 /user/hive/log

8. 修改hive-site.xml

   1. <property>

          <name>hive.metastore.warehouse.dir</name>

          <value>/user/hive/warehouse</value>

          <description>location of default database for the warehouse</description>

        </property>

   2. <property> 

          <name>hive.exec.scratchdir</name> 

          <value>/user/hive/tmp</value> 

      </property>

   3. <property>

          <name>hive.querylog.location</name>

          <value>/user/hive/log</value>

          <description>Location of Hive run time structured log file</description>

      </property>

   4. 連接Mysql數據庫

      <property>

          <name>javax.jdo.option.ConnectionURL</name>

          <value>jdbc:mysql://192.168.174.138:3306/hive?createDatabaseIfNotExist=true</value>  此地址爲本機ip地址

          <description>

            JDBC connect string for a JDBC metastore.

            To use SSL to encrypt/authenticate the connection, provide database-specific SSL flag in the connection URL.

            For example, jdbc:postgresql://myhost/db?ssl=true for postgres database.

          </description>

        </property>

   5. //驅動路徑

      <property>

          <name>javax.jdo.option.ConnectionDriverName</name>

          <value>com.mysql.jdbc.Driver</value>

          <description>Driver class name for a JDBC metastore</description>

      </property>

   6. 登陸mysql用戶名

      <property>

          <name>javax.jdo.option.ConnectionUserName</name>

          <value>root</value>

          <description>Username to use against metastore database</description>

      </property>

   7. //登陸mysql的密碼

      <property>

          <name>javax.jdo.option.ConnectionPassword</name>

          <value>a</value>

          <description>password to use against metastore database</description>

      </property>

9. 修改hive-env.sh 
   1. ​​​​​​​export JAVA_HOME=/home/ubuntu/jdk1.8.0_211
   2. export HADOOP_HOME=/home/ubuntu/hadoop-2.7.6
   3. export HIVE_HOME=/home/ubuntu/hive-2.2.0

   4. export HIVE_CONF_DIR=/home/ubuntu/hive-2.2.0/conf

   5. export HIVE_AUX_JARS_PATH=/home/ubuntu/hive-2.2.0/bin

10. 將mysql驅動包複製到hive的lib目錄下
11. 創建tmp文件

    1. mkdir /usr/local/hive122/tmp

    2. 並在 hive-site.xml 中修改：把{system:java.io.tmpdir} 改成/usr/local/hive122/tmp（三處）

    3. 把 {system:user.name} 改成 {user.name}  （兩處）

12. 初始化mysql

    1. cd  /usr/local/hive122/bin/

    2. ./schematool -initSchema -dbType mysql

13. 執行 hive  如下則安裝成功
