# Hive安装部署 #

1）把apache-hive-3.1.2-bin.tar.gz上传到linux的/opt/software目录下  
2）解压apache-hive-3.1.2-bin.tar.gz到/opt/module/目录下面

tar -zxvf /opt/software/apache-hive-3.1.2-bin.tar.gz -C /opt/module/

3）修改apache-hive-3.1.2-bin.tar.gz的名称为hive

mv /opt/module/apache-hive-3.1.2-bin/ /opt/module/hive

4）修改/etc/profile.d/my\_env.sh，添加环境变量

vim /etc/profile

5）添加内容

#HIVE_HOME
    export HIVE_HOME=/opt/module/hive
    export PATH=$PATH:$HIVE_HOME/bin

source /etc/profile

6）解决日志Jar包冲突，进入/opt/module/hive/lib目录

mv log4j-slf4j-impl-2.10.0.jar log4j-slf4j-impl-2.10.0.jar.bak

# Hive元数据配置到MySql #

## 拷贝驱动 ##

将MySQL的JDBC驱动拷贝到Hive的lib目录下

cp /opt/software/mysql-connector-java-5.1.48.jar /opt/module/hive/lib/

## 配置Metastore到MySql ##

在$HIVE\_HOME/conf目录下新建hive-site.xml文件

vim hive-site.xml

添加如下内容

<?xml version="1.0"?>
    <?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
    <configuration>
        <property>
            <name>javax.jdo.option.ConnectionURL</name>

        </property>
    
        <property>

        </property>
    
        <property>
            <name>hive.cli.print.current.db</name>

        </property>
    </configuration>

# 启动Hive #

## 初始化元数据库 ##

1）登陆MySQL

mysql -uroot -p000000

2）新建Hive元数据库

mysql> create database metastore;
    mysql> quit;

## 启动metastore和hiveserver2 ##

1）Hive 2.x以上版本，要先启动这两个服务，否则会报错：

FAILED: HiveException java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient

2）在/opt/module/hive/bin目录编写hive服务启动脚本

vim hiveservices.sh

内容如下：

#!/bin/bash
    HIVE_LOG_DIR=$HIVE_HOME/logs
    
    mkdir -p $HIVE_LOG_DIR
    
    #检查进程是否运行正常，参数1为进程名，参数2为进程端口
    function check_process()
    { 
        pid=$(ps -ef 2>/dev/null | grep -v grep | grep -i $1 | awk '{print $2}')
        ppid=$(netstat -nltp 2>/dev/null | grep $2 | awk '{print $7}' | cut -d '/' -f 1)
        echo $pid
        [[ "$pid" =~ "$ppid" ]] && [ "$ppid" ] && return 0 || return 1
    }
    
    function hive_start()
    { 
        metapid=$(check_process HiveMetastore 9083)
        cmd="nohup hive --service metastore >$HIVE_LOG_DIR/metastore.log 2>&1 &"
        cmd=$cmd" sleep 4; hdfs dfsadmin -safemode wait >/dev/null 2>&1"
        [ -z "$metapid" ] && eval $cmd || echo "Metastroe服务已启动"
        server2pid=$(check_process HiveServer2 10000)
        cmd="nohup hive --service hiveserver2 >$HIVE_LOG_DIR/hiveServer2.log 2>&1 &"
        [ -z "$server2pid" ] && eval $cmd || echo "HiveServer2服务已启动"
    }
    
    function hive_stop()
    { 
        metapid=$(check_process HiveMetastore 9083)
        [ "$metapid" ] && kill $metapid || echo "Metastore服务未启动"
        server2pid=$(check_process HiveServer2 10000)
        [ "$server2pid" ] && kill $server2pid || echo "HiveServer2服务未启动"
    }
    
    case $1 in
    "start")
        hive_start
        ;;
    "stop")
        hive_stop
        ;;
    "restart")
        hive_stop
        sleep 2
        hive_start
        ;;
    "status")
        check_process HiveMetastore 9083 >/dev/null && echo "Metastore服务运行正常" || echo "Metastore服务运行异常"
        check_process HiveServer2 10000 >/dev/null && echo "HiveServer2服务运行正常" || echo "HiveServer2服务运行异常"
        ;;
    *)
        echo Invalid Args!
        echo 'Usage: '$(basename $0)' start|stop|restart|status'
        ;;
    esac

3）添加执行权限

chmod +x hiveservices.sh

4）启动Hive后台服务

hiveservices.sh start

5）查看Hive后台服务运行情况

hiveservices.sh status
    Metastore服务运行正常
    HiveServer2服务运行异常

6）启动Hive客户端

bin/hive
