安全组没开放端口是原罪！！！导致好多BUG费时费力。Hbase悄悄咪咪的用了好多端口，比如被我抓到的42239，直接搜索报错药不对症。
下载压缩包
可以去官网下载http://hbase.apache.org/downloads.html
也可以去镜像下载历史版本http://archive.apache.org/dist/hbase/
以1.3.2版本为例：
直接下载或者下载到本地再上传都行，看你哪个快。
wget http://archive.apache.org/dist/hbase/1.3.2/hbase-1.3.2-bin.tar.gz tar -zxvf hbase-1.3.2-bin.tar.gz #解压 mv hbase-1.3.2-bin /urs/local/hbase
配置hbase-site.xml
cd /usr/local/hbase/conf vi hbase-site.xml
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
<property>
<name>hbase.rootdir</name>
<value>/hbase-data</value>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>master:2181</value>
</property>
配置hbase-env.sh
cd /usr/local/hbase/conf echo $JAVA_HOME #若没有安装jdk可百度（偷懒） vi hbase-env.sh #添加要一致 export JAVA_HOME=/usr/local/java
运行测试
cd /usr/local/hbase/bin ./start-hbase.sh
ip:16010访问
服务器 vi /etc/hosts
私网ip master
本地 C:\Windows\System32\drivers\etc\hosts
公网ip master
目录结构：
创建一个maven项目并在pom.xml添加依赖：
<dependency>
<groupId>org.apache.hbase</groupId>
<artifactId>hbase-server</artifactId>
<version>1.3.2</version>
</dependency>
<dependency>
<groupId>org.apache.hbase</groupId>
<artifactId>hbase-client</artifactId>
<version>1.3.2</version>
</dependency>
版本是1.3.2，注意和你自己的一致，可以登录hbase shell时查看。

点击运行后需要点耐心等待，灰色INFO、DEBUG信息都可不用管，报错的话会是红色字体（评论区交流），有tomcat内味了。
