[大数据]6.4实训任务 HBase的搭建与使用

前期准备：

1、检测Java安装环境

java -version

2、检测Hadoop安装环境

hadoop version

3、进入hadoop 的 /home/bigdata/Opt/hadoop-2.10.1/sbin 目录后：

cd /home/bigdata/Opt/hadoop-2.10.1/sbin

4、启动 start-dfs.sh 服务

start-dfs.sh

5、查看启动的服务

jps 

1、官网下载HBase

Apache HBase – Apache HBase Downloads

?

直接下载地址：https://dlcdn.apache.org/hbase/2.4.12/hbase-2.4.12-bin.tar.gz

?2、打开 XFTP ，将 HBase 上传到 /home/bigdata/Opt 目录下

3、解压 hbase-2.4.12-bin.tar.gz? 到当前目录

cd /home/bigdata/Opt

tar -zxvf hbase-2.4.12-bin.tar.gz

[root@localhost Opt]# tar -zxvf hbase-2.4.12-bin.tar.gz

在 XFTP 中刷新可查看解压结果

?

HBase的路径为（稍后配置会用到）：

/home/bigdata/Opt/hbase-2.4.12

4、增加环境变量

vim /etc/profile

通过按键盘 ↓? 键 到最下方之前配置过jdk的配置信息处，增加HBase的配置信息：

按键盘 i 进入输入模式

#set Hbase enviroment
export HBASE_HOME=/home/bigdata/Opt/hbase-2.4.12

export PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin:$HADOOP_HOME/sbin:$HADOOP_HOME/bin:$HBASE_HOME/bin

?按 ESC 退出编辑后，输入 :wq 保存并退出

?5、重新加载环境变量

. /ect/profile

6、进入到目录 /home/bigdata/Opt/hbase-2.4.12/conf? 为步骤7、8做准备：

cd /home/bigdata/Opt/hbase-2.4.12/conf

?

7、修改 hbase-env.sh 配置文件

vim hbase-env.sh

按键盘 i 进入输入模式

# set JAVA_HOME
export JAVA_HOME=/home/bigdata/Opt/jdk1.8.0_331

# Tell HBase whether it should manage it's own instance of ZooKeeper or not.
# export HBASE_MANAGES_ZK=true
export HBASE_MANAGES_ZK=false

?按 ESC 退出编辑后，输入 :wq 保存并退出

8、修改 hbase-site.xml 配置文件

vim hbase-site.xml

按键盘 i 进入输入模式?

  <property>
    <name>hbase.rootdir</name>
    <value>hdfs://192.168.232.139:9000/hbase</value>
  </property>
  <property>
    <name>hbase.cluster.distributed</name>
    <!--<value>false</value>-->
    <value>true</value>
  </property>

?按 ESC 退出编辑后，输入 :wq 保存并退出

9、启动 HBase

cd /home/bigdata/Opt/hbase-2.4.12/bin

start-hbase.sh

[root@localhost conf]# cd /home/bigdata/Opt/hbase-2.4.12/bin
[root@localhost bin]# start-hbase.sh

10.在浏览器打开 http://192.168.232.139:50070 查看HBase

说实话，到这里我是打不开这个网址的。发现配置完了，虽然到第9点都是和书上一样的，甚至包括命令运行后的显示内容。但是这时候如果你输入jps命令就发现，没有正在运行的HBase端口。这一点问题我也是个迷，直到 6.5 实训任务 HBase shell 常见命令的使用 中报错 ERROR: KeeperErrorCode = ConnectionLoss for /hbase/master 才发现并没有运行HBase，以及解决办法。----具体可以到6.5中查看我的办法。----

?提示信息如下，等我解决再放上链接：

11.关闭HBase
