【Linux】【hbase】【Hadoop】基于Hadoop安装hbase单机版

前提；

已经安装JDK，本文安装JDK8，路径/home/jdk1.8.0_181，本文环境centos7

1、下载好所需安装包

hadoop-3.0.0.tar.gz（下载地址：https://archive.apache.org/dist/hadoop/core/hadoop-3.0.0/hadoop-3.0.0.tar.gz），hbase-2.1.0-bin.tar.gz（下载地址：http://archive.apache.org/dist/hbase/2.1.0/hbase-2.1.0-bin.tar.gz）

下载速度慢，可以用迅雷下载看看

本文分享迅雷云

hbase-2.1.0-bin.tar.gz的

链接：https://pan.xunlei.com/s/VMSfsbQyvOEvpWSacFLokehBA1
提取码：bf3i

hadoop-3.0.0.tar.gz的

链接：https://pan.xunlei.com/s/VMSfsk_hC_VS_hCKR8ls5TadA1
提取码：uy8d

2、本文把这2个安装包放在/home/hadoop，解压这2个安装包

cd /home/hadoop

tar -zxvf /home/hadoop/hadoop-3.0.0.tar.gz

tar -zxvf /home/hadoop/hbase-2.1.0-bin.tar.gz

3、hosts添加hbase.master

vi /etc/hosts

按i进入编辑

在后面加入192.168.8.71 hbase.master

注意ip为自己Linux的IP地址

按ESC，再按:wq保存退出

4、添加环境变量，添加下面内容，vi /etc/profile，然后重新加载文件source /etc/profile

export HBASE_HOME=/home/hadoop/hbase-2.1.0
export HDFS_NAMENODE_USER=root
export HDFS_DATANODE_USER=root
export HDFS_SECONDARYNAMENODE_USER=root
export YARN_RESOURCEMANAGER_USER=root
export YARN_NODEMANAGER_USER=root

5、hbase的hbase-env.sh文件添加下面内容（HBASE_MANAGES_ZK=true表示用自带的zookeeper），vi /home/hadoop/hbase-2.1.0/conf/hbase-env.sh

export JAVA_HOME=/home/jdk1.8.0_181
export HADOOP_HOME=/home/hadoop/hadoop-3.0.0
export HBASE_HOME=/home/hadoop/hbase-2.1.0
export HBASE_LOG_DIR=/home/hadoop/hbase-2.1.0/logs
export HBASE_CLASSPATH=/home/hadoop/hadoop-3.0.0/etc/hadoop
export HBASE_MANAGES_ZK=true

6、创建hbase的logs目录，mkdir /home/hadoop/hbase-2.1.0/logs

7、hbase的hbase-site.xml文件添加下面内容，注意自己IP，vi /home/hadoop/hbase-2.1.0/conf/hbase-site.xml

    <property>
        <name>hbase.cluster.distributed</name>
        <value>true</value>
    </property>
    <property>
        <name>hbase.tmp.dir</name>
        <value>./tmp</value>
    </property>
    <property>
        <name>hbase.unsafe.stream.capability.enforce</name>
        <value>false</value>
    </property>
    <property>
        <name>hbase.master</name>
        <value>192.168.8.71:60000</value>
    </property>
    <property>
        <name>hbase.master.maxclockskew</name>
        <value>180000</value>
    </property>
    <property>
        <name>hbase.rootdir</name>
        <value>hdfs://192.168.8.71:9000/hbase</value>
    </property>
    <property>
        <name>hbase.cluster.distributed</name>
        <value>true</value>
    </property>
    <property>
        <name>hbase.zookeeper.quorum</name>
        <value>192.168.8.71</value>
    </property>
    <property>
        <name>dfs.replication</name>
        <value>1</value>
    </property>
    <property>
        <name>hbase.zookeeper.property.clientPort</name>
        <value>2181</value>
    </property>
    <property>
        <name>hbase.zookeeper.property.dataDir</name>
        <value>/home/hadoop/hbase-2.1.0/zk_data</value>
    </property>

8、创建上面需要的文件夹mkdir /home/hadoop/hbase-2.1.0/zk_data

9、修改hbase的regionservers文件为自己IP，vi /home/hadoop/hbase-2.1.0/conf/regionservers

10、Hadoop的core-site.xml文件添加下面内容，vi /home/hadoop/hadoop-3.0.0/etc/hadoop/core-site.xml

    <property>
        <name>fs.defaultFS</name>
        <value>hdfs://192.168.8.71:9000</value>
    </property>

 11、Hadoop的hdfs-site.xml文件添加下面内容，vi /home/hadoop/hadoop-3.0.0/etc/hadoop/hdfs-site.xml

    <property>
        <name>dfs.replication</name>
        <value>1</value>
    </property>
    <property>
        <name>dfs.namenode.name.dir</name>
        <value>file:/home/hadoop/hadoop-3.0.0/dfs/name</value>
    </property>
    <property>
        <name>dfs.datanode.data.dir</name>
        <value>file:/home/hadoop/hadoop-3.0.0/dfs/data</value>
    </property>
    <property>
        <name>dfs.permissions</name>
        <value>false</value>
    </property>

 12、创建上面的2个目录

mkdir /home/hadoop/hadoop-3.0.0/dfs

mkdir /home/hadoop/hadoop-3.0.0/dfs/name

mkdir /home/hadoop/hadoop-3.0.0/dfs/data

13、Hadoop的mapred-site.xml文件添加下面内容，注意自己IP，vi /home/hadoop/hadoop-3.0.0/etc/hadoop/mapred-site.xml

    <property>
        <name>mapred.job.tracker</name>
        <value>192.168.8.71:9001</value>
    </property>

14、Hadoop的hadoop-env.sh添加下面内容，vi /home/hadoop/hadoop-3.0.0/etc/hadoop/hadoop-env.sh

export JAVA_HOME=/home/jdk1.8.0_181

15、初始化HDFS系统，/home/hadoop/hadoop-3.0.0/bin/hdfs namenode -format

16、启动Hadoop，/home/hadoop/hadoop-3.0.0/sbin/start-all.sh

 17、启动hbase，/home/hadoop/hbase-2.1.0/bin/start-hbase.sh

 18、启动hbase shell，建表插入数据测试，/home/hadoop/hbase-2.1.0/bin/hbase shell

 

安装过程出现2个意外

1、启动Hadoop报错

 上面第4步，添加的就是解决这个问题

export HDFS_NAMENODE_USER=root
export HDFS_DATANODE_USER=root
export HDFS_SECONDARYNAMENODE_USER=root
export YARN_RESOURCEMANAGER_USER=root
export YARN_NODEMANAGER_USER=root

2、启动hbase后，HMaster启动不了，报错如下，最终标红的才是问题，不是一开始抛出的错误，让人疑惑
