?本篇博客使用到的工具有：VMware16 ，Xftp7

**若不熟悉操作命令，推荐使用带GUI页面的CentOS7虚拟机**

我将使用带GUI页面的虚拟机演示

#### 虚拟机（Virtual Machine） ####

指通过[软件][Link 1]模拟的具有完整[硬件][Link 2]系统功能的、运行在一个完全[隔离][Link 3]环境中的完整[计算机系统][Link 4]。在实体计算机中能够完成的工作在虚拟机中都能够实现。在[计算机][Link 5]中创建虚拟机时，需要将实体机的部分硬盘和内存容量作为虚拟机的硬盘和内存容量。每个虚拟机都有独立的[CMOS][]、硬盘和[操作系统][Link 6]，可以像使用实体机一样对虚拟机进行操作。

#### **【确保服务器集群安装和配置已经完成！】可参考我的上篇博客：** ####

## **前言** ##

--------------------

请根据读者的自身情况，进行相应随机应变。

我的三台CentOS7服务器：  
主机：master（192.168.149.101）  
从机：slave1（192.168.149.102）  
从机：slave2（192.168.149.103）

每一个节点的安装与配置是相同的，在实际工作中，通常在master节点上完成安装和配置后，然后将安装目录通过 scp 命令复制到其他节点即可。

注意：所有操作都是root用户权限，需要我们登陆时选择root用户登录。

--------------------

## zookeeper完全分布式安装 ##

--------------------

### 下载Zookeeper安装包 ###

--------------------

Zookeeper 下载地址：

[Apache ZooKeeper![icon-default.png_t_M85B][]https://zookeeper.apache.org/][Apache ZooKeeper_icon-default.png_t_M85B_https_zookeeper.apache.org]

### 解压Zookeeper安装包 ###

--------------------

首先，需要确保 **network 网络**已经配置好，使用 Xftp 等类似工具进行上传，把 **apache-zookeeper-3.6.2-bin.tar.gz** 上传到 opt/ 目录内。（也可使用U盘等工具拖拽）  
上传完成后，在 master 主机上执行以下代码： 解压zookeeper

cd /opt/
    
    tar -zxvf apache-zookeeper-3.6.2-bin.tar.gz

执行成功后，系统在 **opt** 目录自动创建 **zookeeper-3.6.2** 子目录。

注意：可使用 **ls** 等命令查看文件解压是否无误。

--------------------

### 配置bashrc文件(等同于profile) ###

#zookeeper config
    
    export ZOOKEEPER_HOME=/opt/zookeeper-3.6.2
    
    export PATH=$PATH:$ZOOKEEPER_HOME/bin

**三台虚拟机均进行此操作**

--------------------

### **创建zookeeper数据存放目录** ###

首先，我们可以使用 **ls -l** 命令查看文件权限，并修改文件权限

其中 -R 表示目录 前篇文章已经提到

ls -l
    
    sudo chmod -R 777 /opt/zookeeper-3.6.2

分别在三台虚拟机上执行 **echo id > /opt/zookeeper-3.6.2/myid**  命令创建 zookeeper 编号的 myid 的文件

echo 0 > /opt/zookeeper-3.6.2/myid
    
    echo 1 > /opt/zookeeper-3.6.2/myid
    
    echo 2 > /opt/zookeeper-3.6.2/myid

--------------------

### **编辑zoo.cfg配置文件** ###

将 **zookeeper**  下载后解压到当前用户目录 opt ，然后进入 **zookeeper-3.6.2/conf**，将**zoo\_sample.cfg** 文件复制为 **zoo.cfg** 并编辑

cd zookeper-3.6.2/conf
    
    cp zoo_sample.cfg zoo.cfg
    
    vim zoo.cfg

![9603d95549b949d4a22bbdcd0c008127.png][]

其中 **dataDir**  是zookeeper数据存放位置，**server.y=XXXX:2888:3888** 是zookeeper每台配置的信息，y代表zookeeper编号及myid文件对应的内容，XXXX是服务器对应的IP地址或者主机名

将以上 **zookeeper** 文件复制到三台服务器上

scp -r /opt/zookeeper-3.6.2 root@slave1:/opt
    
    scp -r /opt/zookeeper-3.6.2 root@slave2:/opt

--------------------

### **启动zookeeper** ###

分别在服务器上执行zookeeper服务启动命令

服务器1 master

[root@master bin]# cd /opt/zookeeper-3.6.2/bin/
    
    [root@master bin]# ls
    README.txt    zkCli.sh   zkServer.cmd            zkSnapShotToolkit.cmd  zkTxnLogToolkit.sh
    zkCleanup.sh  zkEnv.cmd  zkServer-initialize.sh  zkSnapShotToolkit.sh
    zkCli.cmd     zkEnv.sh   zkServer.sh             zkTxnLogToolkit.cmd
    [root@master bin]# zkServer.sh start
    
    ZooKeeper JMX enabled by default
    Using config: /opt/zookeeper-3.6.2/bin/../conf/zoo.cfg
    Starting zookeeper ... STARTED

服务器2 slave1

[root@slave1 ~]# cd /opt/zookeeper-3.6.2/bin/
    
    [root@slave1 bin]# zkServer.sh start
    ZooKeeper JMX enabled by default
    Using config: /opt/zookeeper-3.6.2/bin/../conf/zoo.cfg
    Starting zookeeper ... STARTED

服务器3 slave2

[root@slave2 ~]# cd /opt/zookeeper-3.6.2/bin/
    
    [root@slave2 bin]# zkServer.sh start
    ZooKeeper JMX enabled by default
    Using config: /opt/zookeeper-3.6.2/bin/../conf/zoo.cfg
    Starting zookeeper ... STARTED

我们可以使用 status 检查集群状态

master

[root@master bin]# zkServer.sh status
    ZooKeeper JMX enabled by default
    Using config: /opt/zookeeper-3.6.2/bin/../conf/zoo.cfg
    Client port found: 2181. Client address: localhost. Client SSL: false.
    Mode: follower
    
    [root@master bin]#

slave1

[root@slave1 bin]# zkServer.sh status
    ZooKeeper JMX enabled by default
    Using config: /opt/zookeeper-3.6.2/bin/../conf/zoo.cfg
    Client port found: 2181. Client address: localhost. Client SSL: false.
    Mode: leader
    
    [root@slave1 bin]#

slave2

[root@slave2 bin]# zkServer.sh status
    ZooKeeper JMX enabled by default
    Using config: /opt/zookeeper-3.6.2/bin/../conf/zoo.cfg
    Client port found: 2181. Client address: localhost. Client SSL: false.
    Mode: follower
    
    [root@slave2 bin]#

上图中的 leader 及 follower 是集群自动分配

至此 ，zookeeper集群安装完成。

#### 学会了吗？ ####

--------------------

## HBase完全分布式安装 ##

--------------------

###  ###

### 下载HBase安装包 ###

--------------------

[Apache HBase – Apache HBase Downloads![icon-default.png?t=M85B][icon-default.png_t_M85B]https://hbase.apache.org/downloads.html][Apache HBase _ Apache HBase Downloads_icon-default.png_t_M85B_icon-default.png_t_M85B_https_hbase.apache.org_downloads.html]

--------------------

### 上传至master虚拟机并解压HBase ###

--------------------

cd /opt/
    
    tar -zxvf hbase-2.3.3.tar.gz
    
    #修改权限
    sudo chmod -R 777 /opt/hbase-2.3.3

--------------------

### 配置环境变量 ###

--------------------

[root@master ~]# vim /etc/bashrc
    
    
    #HBase
    export HBASE_HOME=/opt/hbase-2.3.3
    export PATH=$PATH:$HBASE_HOME/bin
    
    
    #配置生效
    
    [root@master ~]# source /etc/bashrc

**三台虚拟机均进行此操作**

在这里我们可以使用 hbase -version 查看环境变量是否正确

[root@master ~]# hbase -version
    java version "1.8.0_261"
    Java(TM) SE Runtime Environment (build 1.8.0_261-b12)
    Java HotSpot(TM) 64-Bit Server VM (build 25.261-b12, mixed mode)
    
    [root@master ~]#

--------------------

### 配置hbase相关文件 ###

--------------------

#### 修改及配置 **hbase-2.3.3/conf**  目录下的 **hbase-env.sh** 文件 ####

[root@master ~]# cd /opt/hbase-3.6.2/conf
    [root@master ~]# vim hbase-env.sh
    
    #!/usr/bin/env bash
    
    
    
    # Where log files are stored.  $HBASE_HOME/logs by default.
    # export HBASE_LOG_DIR=${HBASE_HOME}/logs
    
    # Enable remote JDWP debugging of major HBase processes. Meant for Core Developers 
    # export HBASE_MASTER_OPTS="$HBASE_MASTER_OPTS -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8070"
    # export HBASE_REGIONSERVER_OPTS="$HBASE_REGIONSERVER_OPTS -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8071"
    # export HBASE_THRIFT_OPTS="$HBASE_THRIFT_OPTS -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8072"
    # export HBASE_ZOOKEEPER_OPTS="$HBASE_ZOOKEEPER_OPTS -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8073"
    # export HBASE_REST_OPTS="$HBASE_REST_OPTS -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8074"
    
    # A string representing this instance of hbase. $USER by default.
    # export HBASE_IDENT_STRING=$USER
    
    # The scheduling priority for daemon processes.  See 'man nice'.
    # export HBASE_NICENESS=10
    
    # The directory where pid files are stored. /tmp by default.
    export HBASE_PID_DIR=/opt/hadoop/hadoop/pids
    
    # Seconds to sleep between slave commands.  Unset by default.  This
    # can be useful in large clusters, where, e.g., slave rsyncs can
    # otherwise arrive faster than the master can service them.
    # export HBASE_SLAVE_SLEEP=0.1
    
    # Tell HBase whether it should manage it's own instance of ZooKeeper or not.
    # export HBASE_MANAGES_ZK=true
    
    # The default log rolling policy is RFA, where the log file is rolled as per the size defined for the 
    # RFA appender. Please refer to the log4j.properties file to see more details on this appender.
    # In case one needs to do log rolling on a date change, one should set the environment property
    # HBASE_ROOT_LOGGER to "<DESIRED_LOG LEVEL>,DRFA".
    # For example:
    # HBASE_ROOT_LOGGER=INFO,DRFA
    # The reason for changing default to RFA is to avoid the boundary case of filling out disk space as 
    # DRFA doesn't put any cap on the log size. Please refer to HBase-5655 for more context.
    
    # Tell HBase whether it should include Hadoop's lib when start up,
    # the default value is false,means that includes Hadoop's lib.
    export HBASE_DISABLE_HADOOP_CLASSPATH_LOOKUP="true"
    
    # Override text processing tools for use by these launch scripts.
    # export GREP="${GREP-grep}"
    # export SED="${SED-sed}"
    export JAVA_HOME=/opt/jdk1.8.0_261 
    export HBASE_HOME=/opt/hbase-2.3.3
    export HBASE_MANAGES_ZK=false

其中 **HBASE\_MANAGES\_ZK=false** 表示我们使用自己安装 zookeeper 集群而不是 hbase 自带的 zookeeper 集群

#### 修改及配置 hbase-2.3.3/conf 目录下的 hbase-site.xml 文件 ####

[root@master ~]# vim hbase-site.xml
    
    
    <?xml version="1.0"?>
    <?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
    
    <configuration>
    <property>
        <name>hbase.root.dir</name>
        <value>hdfs://master:9000/hbase</value>
    </property>
      <property>
        <name>hbase.cluster.distributed</name>
        <value>true</value>
      </property>
      <property>
        <name>hbase.tmp.dir</name>
        <value>./tmp</value>
      </property>
    <property>
        <name>hbase.zookeeper.quorum</name>
        <value>master,slave1,slave2</value>
    </property>
    <property>
     <name>hbase.zookeeper.property.clientPort</name>	
             <value>2181</value>
     </property>
    
      <property>
        <name>hbase.unsafe.stream.capability.enforce</name>
        <value>false</value>
      </property>
    <property>
        <name>hbase.zookeeper.property.dataDir</name>
        <value>/opt/zookeeper-3.6.2</value>
      </property>
    <property>
        <name>zookeeper.session.timeout</name>
        <value>300000</value>　　 
    </property>
      <property>
    
        <name>hbase.master.maxclockskew</name>
        <value>30000</value>
    
    </property>
    
    </configuration>

#### 添加 hbase 集群服务器的 ip 或者 hostname ，vi regionservers ####

[root@master ~]# vim regionservers
    
    master
    slave1
    slave2

将以上 **Hbase** 文件复制到三台服务器上

scp -r /opt/hbase-2.3.3 root@slave1:/opt
    
    scp -r /opt/hbase-2.3.3 root@slave2:/opt

完成即可

--------------------

### 启动hbase ###

--------------------

配置完成hbase后将上面的所有文件复制到其他两台服务器上，然后使用 **start-hbase.sh**  命令启动hbase集群

[root@master ~]# cd /opt/hbase-2.3.3/bin/
    
    [root@master bin]# ls
    considerAsDead.sh     hbase-config.cmd        master-backup.sh          start-hbase.sh
    draining_servers.rb   hbase-config.sh         region_mover.rb           stop-hbase.cmd
    get-active-master.rb  hbase-daemon.sh         regionservers.sh          stop-hbase.sh
    graceful_stop.sh      hbase-daemons.sh        region_status.rb          test
    hbase                 hbase-jruby             replication               tmp
    hbase-cleanup.sh      hirb.rb                 rolling-restart.sh        zookeepers.sh
    hbase.cmd             local-master-backup.sh  shutdown_regionserver.rb
    hbase-common.sh       local-regionservers.sh  start-hbase.cmd
    
    [root@master bin]# start-hbase.sh
    running master, logging to /opt/hbase-2.3.3/logs/hbase-root-master-master.out
    slave1: running regionserver, logging to /opt/hbase-2.3.3/logs/hbase-root-regionserver-slave1.out
    slave2: running regionserver, logging to /opt/hbase-2.3.3/logs/hbase-root-regionserver-slave2.out
    master: running regionserver, logging to /opt/hbase-2.3.3/logs/hbase-root-regionserver-master.out
    
    [root@master bin]#

在哪台服务器使用上述命令启动则那台服务器即为 master 节点，使用 jps命令查看启动情况

[root@master bin]# jps
    7281 ResourceManager
    8450 HMaster
    6965 SecondaryNameNode
    6535 NameNode
    8619 HRegionServer
    7693 QuorumPeerMain
    8943 Jps

slave1

[root@slave1 bin]# jps
    2180 QuorumPeerMain
    2509 Jps
    1919 DataNode
    2351 HRegionServer
    
    [root@slave1 bin]#

slave2

[root@slave2 ~]# jps
    3441 QuorumPeerMain
    3875 HRegionServer
    4040 Jps
    3165 DataNode
    
    [root@slave2 ~]#

可以看到服务器1启动和  **HMaster** 和 **HRegionServer** 进程，服务器2和服务器3启动和**HRegionServer** 进程。

至此大功告成！！！困扰了我一个月的难题，终于解决了！！！

当然，我们也可以通过Web页面查看 Hbase 集群情况 : http://IP:16010
