开放端口
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。
Hbase安装
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.gztar -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/confvi 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/confecho $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
域名配置
服务器 vi /etc/hosts私网ip master
本地 C:\Windows\System32\drivers\etc\hosts公网ip master
IDEA源码
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。
