Hadoop 伪分布式上安装 Hive

下载地址：点此链接（P.S.下载带bin的安装包）

下载hive后放到虚拟机文件夹内，打开：

tar -zxf /home/tools/apache-hive-1.2.2-bin.tar.gz -C /home/software/

修改并保存环境配置：

gedit /etc/profile

//添加
export HIVE_HOME=/home/software/apache-hive-1.2.2-bin
export PATH=$PATH:$JAVA_HOME/bin:$MAVEN_HOME/bin:$FINDBUGS_HOME/bin:$HBASE_HOME/bin:$HIVE_HOME/bin

source /etc/profile

重命名hive安装目录下的conf文件夹的两个文件名(可以把conf里面带.template的都删掉后缀)：

mv hive-env.sh.template hive-env.sh
mv hive-default.xml.template hive-default.xml

修改hadoop下的etc/hadoop/hadoop-env.sh：

export HADOOP_CLASSPATH=.$CLASSPATH:$HADOOP_CLASSPATH:$HADOOP_HOME/bin

 修改hive下的/bin/hive-config.sh：添加下面三行：

export JAVA_HOME=/home/software/jdk1.8.0_151
export HADOOP_HOME=/home/software/hadoop-2.6.5
export HIVE_HOME=/home/software/apache-hive-1.2.2-bin

 新建hive-site.xml :

touch hive-site.xml

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<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>
    <value>hive</value>
    <description>username to use against metastore database</description>
  </property>
  <property>
    <name>javax.jdo.option.ConnectionPassword</name>
    <value>hive</value>
    <description>password to use against metastore database</description>
  </property>
</configuration>

安装mysql：点此链接

下载mysql jdbc 包：点此链接

tar -zxvf mysql-connector-java-5.1.40.tar.gz   #解压
cp mysql-connector-java-5.1.40/mysql-connector-java-5.1.40-bin.jar /home/software/apache-hive-1.2.2-bin/lib 

//将mysql-connector-java-5.1.40-bin.jar拷贝到hive的lib目录下

启动并登陆mysql shell

service mysql start //启动mysql服务
mysql -u root -p  //登陆shell界面

新建hive数据库

mysql> create database hive;    //这个hive数据库与hive-site.xml中localhost:3306/hive的hive对应，用来保存hive元数据

配置mysql允许hive接入：

mysql> grant all on *.* to hive@localhost identified by 'hive';   //将所有数据库的所有表的所有权限赋给hive用户，后面的hive是配置hive-site.xml中配置的连接密码
mysql> flush privileges;  //刷新mysql系统权限关系表

启动hive,在hive目录下
(启动hive之前，请先启动hadoop集群。)

hive  //启动hive
