HBase完全分布式安装

1.下载到服务器

2.下载解压

3.修改conf/hbase-env.sh

4.\#修改JAVA\_HOME：export JAVA\_HOME=xxxx

5.\#修改Zookeeper和Hbase的协调模式，

6.保存，重新加载配置文件

7.修改hbase-site.xml，配置开启完全分布式模式

8.配置region服务器,修改conf/regionservers文件,每个主机名独占一行，

9.拷贝其他服务器上

10.启动Hadoop伪分布式(先启动zookeeper集群)

11.启动zookeeper集群

12.启动Hbase

13.查看节点

14.查看其他节点信息

15.防止主节点单点故障

16.查看各节点的java进程是否正确

17.关闭Hmaster

18.关闭regionserver

--------------------

## 1.下载到服务器 ##

wget [http://bj-yzjd.ufile.cn-north-02.ucloud.cn/hbase-0.98.17-hadoop2-bin.tar.gz][http_bj-yzjd.ufile.cn-north-02.ucloud.cn_hbase-0.98.17-hadoop2-bin.tar.gz]

## 2.下载解压 ##

## 3.修改conf/hbase-env.sh ##

## **4.\#修改JAVA\_HOME：export JAVA\_HOME=xxxx** ##

**cat /etc/profile   查看所有的配置文件路径**

## 5.\#修改Zookeeper和Hbase的协调模式， ##

**hbase默认使用自带的zookeeper，如果需要使用外部zookeeper，需要先关闭：**

**export HBASE\_MANAGES\_ZK=false**

## 10.启动Hadoop伪分布式(先启动zookeeper集群) ##

![20190709182528871.png][]

## 11.启动zookeeper集群 ##

**sh zkServer.sh start**

## 12.启动Hbase ##

出现黄色字体，启动成功，

## 13.查看节点 ##

![20190709182714400.png][]

## 14.查看其他节点信息 ##

**之前疏忽把JDK安装目录配置错误，更改之后，查看其他节点信息**

## 15.防止主节点单点故障 ##

**在其他节点单独启动一个Hbase**

## 16.查看各节点的java进程是否正确 ##

**通过浏览器访问http://xxxxx:60010来访问web界面，通过web见面管理hbase**

## 17.关闭Hmaster ##

**进入到hbase安装目录下的bin目录，执行：stop-hbase.sh**

## 18.关闭regionserver ##

**进入到hbase安装目录下的bin目录，执行：sh hbase-daemon.sh stop regionserver**
