# 一、基本信息 #

官网 [http://hbase.apache.org/][http_hbase.apache.org]  
官方文档 [http://hbase.apache.org/book.html\#arch.overview][http_hbase.apache.org_book.html_arch.overview]  
w3cschool [https://www.w3cschool.cn/hbase\_doc/][https_www.w3cschool.cn_hbase_doc]  
易佰教程 [https://www.yiibai.com/hbase][https_www.yiibai.com_hbase]  
Hbase 版本与 Hadoop 的兼容性  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xsd3kxNDI4_size_16_color_FFFFFF_t_70]

# 二、基础环境准备 #

1、[Hadoop 完全分布式搭建][Hadoop]  
2、启动 hdfs 服务

[root@master ~]# /usr/bigdata/hadoop-3.3.0/sbin/start-dfs.sh

3、[安装部署 Zookeeper 3.6.2 集群][Zookeeper 3.6.2]  
4、启动各节点的 zkServer 服务

[root@slave1 ~]# /usr/bigdata/apache-zookeeper-3.6.2-bin/bin/zkServer.sh start
    [root@slave2 ~]# /usr/bigdata/apache-zookeeper-3.6.2-bin/bin/zkServer.sh start
    [root@slave3 ~]# /usr/bigdata/apache-zookeeper-3.6.2-bin/bin/zkServer.sh start

# 三、Hbase 安装部署 #

1、在 master 节点下载 hbase 安装包文件

[root@master ~]# wget -P /usr/bigdata/ https://mirror.bit.edu.cn/apache/hbase/2.4.0/hbase-2.4.0-bin.tar.gz

效果如下  
![在这里插入图片描述][20201224231850381.png]  
2、进入文件下载目录

[root@master ~]# cd /usr/bigdata/

3、解压文件

[root@master bigdata]# tar zxf hbase-2.4.0-bin.tar.gz

4、查看目录

[root@master bigdata]# ll

效果如下  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xsd3kxNDI4_size_16_color_FFFFFF_t_70 1]  
5、进入 hbase 的配置文件目录

[root@master ~]# cd /usr/bigdata/hbase-2.4.0/conf

查看目录  
![在这里插入图片描述][2020122423263460.png]  
6、编辑文件 hbase-env.sh

[root@master conf]# vim hbase-env.sh

编辑文件

export JAVA_HOME="/usr/lib/jvm/java-1.8.0"
    export HBASE_PID_DIR="/usr/bigdata/hbase-2.4.0/"
    export HBASE_MANAGES_ZK=false

7、编辑文件 regionservers  
官网说明  
![在这里插入图片描述][2020122600032823.png]

[root@master conf]# vim regionservers

编辑内容

slave1
    slave2
    slave3

8、编辑文件 backup-masters  
官网说明  
![在这里插入图片描述][20201226000437837.png]

[root@master conf]# vim backup-masters

编辑内容

slave1

9、创建目录

[root@master ~]# mkdir /usr/bigdata/hbase-2.4.0/tmp

10、编辑文件 hbase-site.xml

[root@master conf]# vim hbase-site.xml

编辑内容

<configuration>
      <property>
        <name>hbase.cluster.distributed</name>
        <value>true</value>
      </property>
      
      <property>
        <name>hbase.rootdir</name>
        <value>hdfs://master:9820/hbase</value>
      </property>
      
      <property>
        <name>hbase.zookeeper.quorum</name>
        <value>slave1:2181,slave2:2181,slave3:2181</value>
      </property>
      
      <property>
        <name>hbase.zookeeper.property.dataDir</name>
        <value>/usr/bigdata/apache-zookeeper-3.6.2-bin</value>
      </property>
      
      <property>
        <name>hbase.zookeeper.property.clientPort</name>
        <value>2181</value>
      </property>
      <property>
        <name>hbase.tmp.dir</name>
        <value>/usr/bigdata/hbase-2.4.0/tmp/</value>
      </property>
      <property>
        <name>hbase.unsafe.stream.capability.enforce</name>
        <value>false</value>
      </property>
      <property>
        <name>dfs.datanode.max.transfer.threads</name>
        <value>4096</value>
      </property>
      
      <property>
        <name>hbase.wal.provider</name>
        <value>filesystem</value>
      </property>
    </configuration>

11、把hadoop下的 hdfs-site.xml 文件拷贝到 /usr/bigdata/hbase-2.4.0/conf 目录下  
官网说明  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xsd3kxNDI4_size_16_color_FFFFFF_t_70 2]

[root@master ~]# cp /usr/bigdata/hadoop-3.3.0/etc/hadoop/hdfs-site.xml /usr/bigdata/hbase-2.4.0/conf/

12、把配置好的 hbase 文件信息发售给集群的 hbase 子节点

[root@master ~]# scp -r /usr/bigdata/hbase-2.4.0 root@slave1:/usr/bigdata/
    [root@master ~]# scp -r /usr/bigdata/hbase-2.4.0 root@slave2:/usr/bigdata/
    [root@master ~]# scp -r /usr/bigdata/hbase-2.4.0 root@slave3:/usr/bigdata/

13、编辑系统环境变量

[root@master ~]# vim /etc/profile

14、编辑内容

export JAVA_HOME="/usr/lib/jvm/java-1.8.0"
    export JRE_HOME="/usr/lib/jvm/java-1.8.0/jre"
    export HADOOP_HOME="/usr/bigdata/hadoop-3.3.0"
    export HBASE_HOME="/usr/bigdata/hbase-2.4.0"
    
    export PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$HBASE_HOME/bin
    export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$HADOOP_HOME/share/hadoop/common/*:$HADOOP_HOME/share/hadoop/common/lib/*:$HBASE_HOME/lib
    
    export HADOOP_HDFS_HOME=$HADOOP_HOME
    export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
    export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib:$HADOOP_HOME/lib/native"

15、时配置后的环境变量生效

[root@master ~]# source /etc/profile

16、查看 hbase 的 bin 目录

[root@master ~]# cd /usr/bigdata/hbase-2.4.0/bin

bin 目录文件列表如下  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xsd3kxNDI4_size_16_color_FFFFFF_t_70 3]  
17、启动 hbase 服务

[root@master ~]# /usr/bigdata/hbase-2.4.0/bin/start-hbase.sh

启动效果如下  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xsd3kxNDI4_size_16_color_FFFFFF_t_70 4]  
18、查看各个节点上 hbase 各服务的启动状态  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xsd3kxNDI4_size_16_color_FFFFFF_t_70 5]  
19、查看服务所占端口

[root@master ~]# netstat -lntp

![在这里插入图片描述][20201226184407530.png]  
20、查看其在 HDFS 中的存储信息

[root@master ~]# hdfs dfs -ls /hbase
    或
    [root@master ~]# hadoop fs -ls /hbase

存储文件列表如下  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xsd3kxNDI4_size_16_color_FFFFFF_t_70 6]  
21、在任一节点 运行 hbase shell

[root@slave1 ~]# hbase shell

如下图  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xsd3kxNDI4_size_16_color_FFFFFF_t_70 7]  
22、停止 hbase 服务

[root@master ~]# /usr/bigdata/hbase-2.4.0/bin/stop-hbase.sh

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xsd3kxNDI4_size_16_color_FFFFFF_t_70 8]

# 四、Hbase 基本命令 #

hbase:001:0> list
    TABLE

# 五、浏览器查看服务的 WEB #

Hbase master 节点的默认端口是 16000  
官网  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xsd3kxNDI4_size_16_color_FFFFFF_t_70 9]

浏览器录入地址 http://192.168.11.21:16010/ 说明：192.168.11.21 是 master 节点的 IP  
效果如下  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xsd3kxNDI4_size_16_color_FFFFFF_t_70 10]

# 六、报错及解决方案 #

启动 hbase 服务或者运行hbase shell命令的时候如果有如下报错  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xsd3kxNDI4_size_16_color_FFFFFF_t_70 16]  
其原因可能有两种  
1、hadoop 的 hdfs 启动状态为安全模式  
hadoop 的 hdfs 启动状态为安全模式的解决方案  
查看安全模式状态

[root@master ~]# hadoop dfsadmin -safemode get

状态结果

Safe mode is ON    （安全模式已开启）
    Safe mode is OFF   （安全模式已关闭）

关闭安全模式

[root@master ~]# hadoop dfsadmin -safemode leave
    或
    [root@master ~]# dhfs dfsadmin -safemode leave

重启各节点 Hbase 相关服务。

2、缺少 “文件异步读写配置” 的配置信息  
查找日志信息

[root@master ~]# cat /usr/bigdata/hbase-2.4.0/logs/hbase-root-master-master.log

发现以下问题  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xsd3kxNDI4_size_16_color_FFFFFF_t_70 17]  
编辑配置文件

[root@master ~]# vim /usr/bigdata/hbase-2.4.0/conf/hbase-site.xml

增加配置信息

<property>
      <name>hbase.wal.provider</name>
      <value>filesystem</value>
    </property>

重启各节点 Hbase 相关服务。
