hive部署

1. 下载hive安装包：https://dlcdn.apache.org/hive/hive-2.3.9/
2. 解压及环境部署

tar -zxvf apache-hive-2.3.9-bin.tar.gz
mv apache-hive-2.3.9-bin hive

vim /etc/profile

添加至环境变量
export HIVE_HOME=/usr/local/hive
export PATH=$PATH:$HIVE_HOME/bin

source /etc/profile

编写配置文件

vim 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.cj.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>

3. 安装mysql

sudo apt-get update  #更新软件源
sudo apt-get install mysql-server  #安装mysq

验证

service mysql start
sudo netstat -tap | grep mysql
mysql -u root -p #进入mysql shell 

配置：

mysql> create user 'hive'@'localhost' identified by 'hive'; #创建用户hive,密码hive
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
mysql> grant all on *.* to 'hive'@'localhost';#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#刷新权限

下载mysql jdbc 包
https://dev.mysql.com/downloads/connector/j/

tar -zxvf  mysql-connector-j-8.1.0.tar.gz
mv mysql-connector-j-8.1.0 ../mysql
cp mysql/mysql-connector-j-8.1.0.jar  /usr/local/hive/lib

注意
4. 启动hive

start-all.sh #启动hadoop
schematool -initSchema -dbType mysql #执行初始化操作
hive  #启动hive

验证

show tables;
