## 环境
操作系统 | 主机名 | 地址 | 运行组件
---- | ---- | ---- | ----
Rocky9 | hive-hs20 | 192.168.8.20/24 | Hive Server
Rocky9 | hive-ms21 | 192.168.8.21/24 | Hive Metastore, MySQL8.0
## 服务器初始配置
- 在**全部主机**上执行如下操作
- 禁用防火墙
- 禁用 selinux
- 配置时间同步
- 配置主机名解析
```bash
echo "192.168.8.1 hdp-nn" >> /etc/hosts
echo "192.168.8.2 hdp-snn" >> /etc/hosts
echo "192.168.8.3 hdp-dn" >> /etc/hosts
echo "192.168.8.10 hdp-slave10" >> /etc/hosts
echo "192.168.8.11 hdp-slave11" >> /etc/hosts
echo "192.168.8.20 hdp-hs20" >> /etc/hosts
echo "192.168.8.21 hdp-ms21" >> /etc/hosts
```
## 创建 mysql 数据库
- 在 **hive-ms21** 上执行如下操作
- 部署 mysql8.0，略过
- 创建用户及其数据库，参考 sql 如下
```sql
create user hive@127.7.7.7 identified by 'Hive_1234';
create database hive default charset utf8mb4;
grant all on hive.* to hive@127.7.7.7;
```
## 复制 jdk 和 hadoop 环境
- 在**全部主机**上执行如下操作
- 从 hdp-nn 复制 jdk 和 hadoop 环境
```bash
scp -r hdp-nn:/opt/{jdk,hdp} /opt/
scp hdp-nn:/etc/profile.d/{jdk,hdp}.sh /etc/profile.d/
source /etc/profile.d/jdk.sh
source /etc/profile.d/hdp.sh
```
## 部署 hive 环境
- 在**全部主机**上执行如下操作
- 下载 hive 2.3.9 部署包，解压
```bash
curl -LO https://archive.apache.org/dist/hive/hive-2.3.9/apache-hive-2.3.9-bin.tar.gz
tar zxf apache-hive-2.3.9.tar.gz
mv apache-hive-2.3.9 /opt/hive
```
- 下载 mysql 连接库，解压到 hive 库目录下
```bash
curl -LO https://downloads.mysql.com/archives/get/p/3/file/mysql-connector-j-8.0.33.tar.gz
tar zxf mysql-connector-j-8.0.33.tar.gz mysql-connector-j-8.0.33/mysql-connector-j-8.0.33.jar
mv mysql-connector-j-8.0.33/mysql-connector-j-8.0.33.jar /opt/hive/lib/
rm -rf mysql-connector-j-8.0.33*
```
- 配置环境变量
```bash
echo 'export HIVE_HOME=/opt/hive' > /etc/profile.d/hive.sh
echo 'export PATH=$HIVE_HOME/bin:$PATH' >> /etc/profile.d/hive.sh
source /etc/profile.d/hive.sh
```
### 修改 hive-env.sh
- 编辑 $HIVE_HOME/conf/hive-env.sh，指定 HADOOP_HOME 环境变量
```bash
export HADOOP_HOME=/opt/hdp
```
### 创建 hive-site.xml
- 创建 $HIVE_HOME/conf/hive-site.xml，参考内容如下
```xml
<configuration>
<property>
<!-- mysql 地址 -->
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://127.7.7.7:3306/hive?createDatabaseIfNotExist=true&amp;useSSL=false</value>
</property>

<value>/hive/warehouse</value>
</property>
<property>
<!-- hive metastore 端口-->
<name>hive.metastore.uris</name>
<value>thrift://hive-ms:9083</value>
</property>
<!-- hive 使用 tez 引擎
<property>

<value>tez</value>
</property> -->
<property>

```
## 初始化 hive 库
- 在 **hive-ms21** 上执行如下操作
```bash
schematool -dbType mysql -initSchema
```
## 启动 hive
- 在 **hive-ms21** 上启动 hive metastore
```bash
hive --service metastore
```
- 在 **hive-hs20** 上启动 hive server
```bash
hive --service hiveserver2
```
## 客户端连接
- 本地直接连接
```bash
hive
```
- beeline 连接，需要[在 $HADOOP_HOME/etc/hadoop/core-site.xml 中配置 proxyuser](/hdp2#修改 core-site.xml)
```bash
beeline -u jdbc:hive2://hive-hs20:10000 -n root
```
