hive的安裝比較簡單，只需要在一臺機器上配置即可。

由於hive的一些功能要藉助資料庫實現，所以要先裝好mysql。

一.安裝MySql

1.下載MySQL

# 下載mysql源安裝包
shell> wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
# 安裝mysql源
shell> yum localinstall mysql57-community-release-el7-8.noarch.rpm

2、安裝MySQL

shell> yum install mysql-community-server
 

shell> systemctl start mysqld

檢視MySQL的啟動狀態

shell> systemctl status mysqld
● mysqld.service - MySQL Server
   Loaded: loaded (/usr/lib/systemd/system/mysqld.service; disabled; vendor preset: disabled)
   Active: active (running) since 五 2016-06-24 04:37:37 CST; 35min ago
 Main PID: 2888 (mysqld)
   CGroup: /system.slice/mysqld.service
           └─2888 /usr/sbin/mysqld --daemonize --pid-file=/var/run/mysqld/mysqld.pid

6月 24 04:37:36 localhost.localdomain systemd[1]: Starting MySQL Server...
6月 24 04:37:37 localhost.localdomain systemd[1]: Started MySQL Server.
 

4.設定開機啟動

shell> systemctl enable mysqld
shell> systemctl daemon-reload

mysql安裝完成之後，在/var/log/mysqld.log檔案中給root生成了一個預設密碼。通過下面的方式找到root預設密碼，然後登入mysql進行修改：

shell> grep 'temporary password' /var/log/mysqld.log

shell> mysql -uroot -p
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!'; 
 

或者

mysql> set password for 'root'@'localhost'=password('MyNewPass4!');

二.安裝hive

1.下載安裝檔案並解壓

wget http://mirrors.cnnic.cn/apache/hive/hive-1.2.1/apache-hive-1.2.1-bin.tar.gz
tar -zxvf apache-hive-1.2.1-bin.tar.gz 

vi /etc/profile 在最後新增：

export HIVE_HOME=/home/hadoop/apache-hive-2.1.1-bin  
export PATH=$HIVE_HOME/bin:$HIVE_HOME/conf:$PATH 

source /etc/profile

3.修改hive配置檔案

切換到hive安裝目錄的conf資料夾下

vi hive-site.xml

<configuration>
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true</value>
<description>JDBC connect string for a JDBC metastore</description>
</property>

<property>
<name>javax.jdo.option.ConnectionDriverName</name>
<value>com.mysql.jdbc.Driver</value>
<description>Driver class name for a JDBC metastore</description>
</property>

<property>
<name>javax.jdo.option.ConnectionUserName</name>
<!-- 使用者名稱 -->
<value>root</value>
<description>username to use against metastore database</description>
</property>

<property>
<name>javax.jdo.option.ConnectionPassword</name>
<!-- 密碼 -->
<value>root</value>
<description>password to use against metastore database</description>
</property>
</configuration>

即將mysql-connector-java-5.1.6-bin.jar拷貝到hive的lib目錄下。

5. Jline包版本不一致的問題

在hive 的lib目錄下找到jline-2.12.jar，將其拷貝到hadoop目錄下

share/hadoop/yarn/lib/jline-0.9.94.jar

三、啟動測試hive

切換到hive安裝目錄，執行

bin/hive

出現下圖表示啟動成功：

配置完成。
