hbase完全分布式安装

完全分布式安装需要一个hadoop集群和hbase集群

为防止服务器宕机导致数据丢失，公司一般采用此模式。如果是个人测试使用，建议安装伪分布式 https://www.cnblogs.com/hzcjd/p/13868391.html

1安装hadoop集群

启动hbase前先得启动hadoop

安装方法见 hadoop完全分布式安装 https://www.cnblogs.com/hzcjd/p/13669423.html

2 部署图

	NN-1	NN-2	DN	ZK	master	regionserver	IP地址
Node01	*				*		192.168.21.148
Node02		*	*	*		*	192.168.21.147
Node03			*	*		*	192.168.21.143
Node04			*	*		*	192.168.21.146
Node05					*		192.168.21.152

带*代表此机器需启动的应用

从上图可见hmaster分别安装在node01和node05机器上

3 解压

cd /usr/local/software
tar zxvf hbase-2.2.2-bin.tar.gz -C /usr/local

4 时间服务器同步

vim /etc/profile

export HBASE_HOME=/usr/local/hbase-2.2.2

path=HBASE_HOME/bin

7 配置修改160010

hbase-env.sh

cd  /usr/local/hbase-2.2.2/conf
vim hbase-env.sh  输入
export JAVA_HOME=/usr/local/jdk
export HBASE_MANAGES_ZK=false
:wq

hbase-site.xml

<property>
<name>hbase.rootdir</name>
<value>hdfs://mycluster:8020/hbase</value>
</property>

</property>
<property>
       <name>hbase.unsafe.stream.capability.enforce</name>
        <value>false</value>
</property>

hdfs://mycluster:8020/hbase 与hadoop中的hdfs.site一致

Regionservers

vim regionservers
输入
node02
node03
node04
:wq

Backup-masters

vim backup-masters输入
node05
:wq

拷贝hdfs.xml

cp /usr/local/hadoop-3.2.0-ha/etc/hadoop/hdfs-site.xml ./
