Hbase安装部署

Hbase解压和配置环境变量

• 解压Hbase压缩包

[[email protected] software]$ tar -zxvf hbase-2.0.5-bin.tar.gz -C /home/lqs/module

• 配置环境变量

[[email protected] bin]$ sudo vim /etc/profile.d/my_env.sh

#HBASE_HOME
export HBASE_HOME=/home/lqs/module/hbase-2.0.5
export PATH=$PATH:$HBASE_HOME/bin

配置文件

1.hbase-env.sh修改内容：

[[email protected] conf]$ pwd
/home/lqs/module/hbase-2.0.5/conf
[[email protected] conf]$ vim hbase-env.sh

export HBASE_MANAGES_ZK=false

• hbase-site.xml修改内容

[[email protected] conf]$ vim hbase-site.xml

<configuration>

    <property>
        <name>hbase.rootdir</name>
        <value>hdfs://bdc112:8020/hbase</value>
    </property>

    <property>
        <name>hbase.cluster.distributed</name>
        <value>true</value>
    </property>

    <property>
        <name>hbase.zookeeper.quorum</name>
        <value>bdc112,bdc113,bdc114</value>
    </property>

</configuration>

• regionservers 修改

[[email protected] conf]$ vim regionservers 

添加如下内容：

bdc112
bdc113
bdc114

分发Hbase到其它节点

[[email protected] module]$ xsync hbase-2.0.5/

Hbase服务启动

注意：启动Hbase前一定要启动hadoop集群和Zookeeper集群！！！

1、单点启动

[[email protected] hbase-2.0.5]$ bin/hbase-daemon.sh start master

[[email protected] hbase-2.0.5]$ bin/hbase-daemon.sh start master regionserver

2、群启

[[email protected] hbase-2.0.5]$ start-hbase.sh

3、群停

[[email protected] ~]$ stop-hbase.sh 
stopping hbase..........

查看HBase页面

启动成功后，可以通过“host:port”的方式来访问HBase管理页面，例如：

http://bdc112:16010 

页面如下：

配置HBase集群的高可用

意义或者是作用：
在HBase中HMaster负责监控HRegionServer的生命周期，均衡RegionServer的负载，如果HMaster挂掉了，那么整个HBase集群将陷入不健康的状态，并且此时的工作状态并不会维持太久。所以HBase支持对HMaster的高可用配置。

1、关闭Hbase集群，没有开启不用管
stop-hbase.sh(需要配置好环境变量，否则只能在hbase的bin下用）
2、在conf目录下创建backup-masters文件

[[email protected] conf]$ pwd
/home/lqs/module/hbase-2.0.5/conf
[[email protected] conf]$  vim backup-masters

输入：bdc1113
注意：这个备份节点可以设置多个，且可以任意设置

3、分发到集群的其他节点

[[email protected] conf]$ pwd
/home/lqs/module/hbase-2.0.5/conf
[[email protected] conf]$ xsync backup-masters 
==================== bdc112 ====================
sending incremental file list

sent 62 bytes  received 12 bytes  148.00 bytes/sec
total size is 7  speedup is 0.09
==================== bdc113 ====================
sending incremental file list
backup-masters

sent 116 bytes  received 35 bytes  302.00 bytes/sec
total size is 7  speedup is 0.05
==================== bdc114 ====================
sending incremental file list
backup-masters

sent 116 bytes  received 35 bytes  100.67 bytes/sec
total size is 7  speedup is 0.05

4、重新群启Hbase

[[email protected] conf]$ start-hbase.sh 
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/home/lqs/module/hbase-2.0.5/lib/slf4j-log4j12-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class]
