二.Hbase 配置

1.单机部署

## 1.创建安装目录
mkdir -p /usr/local/hbase
## 2.将压缩包拷贝到虚拟机并解压缩
tar zxvf hbase-3.0.0-alpha-4-bin.tar.gz -C /usr/local/hbase/
## 3.添加环境变量
echo 'export HBASE_HOME=/usr/local/hbase/hbase-3.0.0-alpha-4' >> /etc/profile
echo 'export PATH=${HBASE_HOME}/bin:${PATH}' >> /etc/profile
source /etc/profile
## 4.指定 JDK 版本
echo 'export JAVA_HOME=/usr/local/java/jdk-11.0.19' >> $HBASE_HOME/conf/hbase-env.sh
## 5.创建 hbase 存储目录
mkdir -p /home/hbase/data
## 6.修改配置
vim $HBASE_HOME/conf/hbase-site.xml添加如下信息<property><name>hbase.rootdir</name><value>file:///home/hbase/data</value></property>

## 1.进入安装目录
cd $HBASE_HOME
## 2.启动服务
./bin/start-hbase.sh

## 1.进入安装目录
cd $HBASE_HOME
## 2.关闭服务
./bin/stop-hbase.sh

2.伪集群部署（基于单机配置）

## 1.修改 hbase-env.sh 
echo 'export JAVA_HOME=/usr/local/java/jdk-11.0.19' >> $HBASE_HOME/conf/hbase-env.sh
echo 'export HBASE_MANAGES_ZK=true' >> $HBASE_HOME/conf/hbase-env.sh
## 2.修改 hbase_site.xml
vim $HBASE_HOME/conf/hbase-site.xml<!-- 将 hbase 数据保存到 hdfs --><property><name>hbase.rootdir</name><value>hdfs://nn/hbase</value></property><!-- 分布式配置 --><property><name>hbase.cluster.distributed</name><value>true</value></property><!-- 配置 ZK 地址 --><property><name>hbase.zookeeper.quorum</name><value>nn</value></property><!-- 配置 JK 地址 --><property><name>dfs.replication</name><value>1</value></property>
## 3.修改 regionservers 的 localhost 为 nn
echo nn > $HBASE_HOME/conf/regionservers

在这里插入图片描述

## 1.进入安装目录
cd $HADOOP_HOME
## 2.启动 hadoop 服务
./sbin/start-all.sh

在这里插入图片描述

## 1.进入安装目录
cd $HBASE_HOME
## 2.启动服务
./bin/start-hbase.sh

在这里插入图片描述

## 1.进入安装目录
cd $HBASE_HOME
## 2.关闭主节点服务（直接关服务是关不掉的，如图）
. bin/hbase-daemon.sh stop master
## 3.关闭服务
./bin/stop-hbase.sh

在这里插入图片描述

3.集群部署

## 1.创建 zookeeper 数据目录
mkdir -p $HBASE_HOME/zookeeper/data
## 2.进入安装目录
cd $HBASE_HOME/conf
## 3.修改环境配置
vim hbase-env.sh
## 添加 JDK / 启动外置 Zookeeper# JDKexport JAVA_HOME=/usr/local/java/jdk-11.0.19# Disable Zookeeperexport HBASE_MANAGES_ZK=false
## 4.修改 hbase-site.xml
vim hbase-site.xml
## 配置如下信息<!--允许的最大同步时钟偏移--><property><name>hbase.master.maxclockskew</name>`<value>6000</value></property><!--配置 HDFS 存储实例--><property><name>hbase.rootdir</name><value>hdfs://nn:9000/hbase</value></property><!--启用分布式配置--><property><name>hbase.cluster.distributed</name><value>true</value></property><!--配置 zookeeper 集群节点--><property><name>hbase.zookeeper.quorum</name><value>zk1,zk2,zk3</value></property><!--配置 zookeeper 数据目录--><property><name>hbase.zookeeper.property.dataDir</name><value>/usr/local/hbase/hbase-3.0.0-alpha-4/zookeeper/data</value></property><!-- Server is not running yet --><property><name>hbase.wal.provider</name><value>filesystem</value></property>
## 5.清空 regionservers 并添加集群节点域名
echo '' > regionservers
echo 'nn' >> regionservers
echo 'nd1' >> regionservers
echo 'nd2' >> regionservers
## 6.分别为 nd1 / nd2 创建 hbase 目录
mkdir -p /usr/local/hbase
## 7.分发 hbase 配置到另外两台虚拟机 nd1 / nd2
scp -r /usr/local/hbase/hbase-3.0.0-alpha-4 root@nd1:/usr/local/hbase
scp -r /usr/local/hbase/hbase-3.0.0-alpha-4 root@nd2:/usr/local/hbase
## 8.分发环境变量配置
scp /etc/profile root@nd1:/etc/profile
scp /etc/profile root@nd2:/etc/profile

1.启动 hadoop 集群

Hadoop 集群搭建参考：Hadoop 搭建

## 1.启动 hadoop
cd $HADOOP_HOME
. sbin/start-all.sh

在这里插入图片描述

## 1.关闭 hadoop 安全模式
hadoop dfsadmin -safemode leave

在这里插入图片描述

2.启动 zookeeper 集群

ZOOKEEPER 集群搭建说明

## 1.启动 zookeeper 集群
zkServer.sh start && ssh root@zk2 "source /etc/profile && zkServer.sh start && exit" && ssh root@zk3 "source /etc/profile && zkServer.sh start && exit"
## 2.查看状态
zkServer.sh status && ssh root@zk2 "source /etc/profile && zkServer.sh status && exit" && ssh root@zk3 "source /etc/profile && zkServer.sh status && exit"

3.启动 hbase 集群

## 1.分别为 nn /nd1 / nd2 配置 zookeeper 域名解析
echo '192.168.1.100 zk1' >> /etc/hosts
echo '192.168.1.101 zk2' >> /etc/hosts
echo '192.168.1.102 zk3' >> /etc/hosts
## 2.启动 habase
cd $HBASE_HOME
. bin/start-hbase.sh
## 3.停止服务
. bin/hbase-daemon.sh stop master
. bin/hbase-daemon.sh stop regionserver
. bin/stop-hbase.sh

4.集群启停脚本

#!/bin/bashcase $1 in
"start")## start hadoopstart-all.sh## start zookeeper (先配置免密登录)zkServer.sh start && ssh root@zk2 "source /etc/profile && zkServer.sh start && exit" && ssh root@zk3 "source /etc/profile && zkServer.sh start && exit"## start hbasestart-hbase.sh;;

*)echo "pls inout start|stop";;
esac

三.测试

## 1.为 Windows 增加 Hosts 配置，添加 Hbase 集群域名解析 编辑如下文件
C:\Windows\System32\drivers\etc\hosts
## 2.增加如下信息
192.168.1.6 nn
192.168.1.7 nd1
192.168.1.8 nd2
