hbase高可用集群部署（cdh）

一、概要

    本文记录hbase高可用集群部署过程，在部署hbase之前需要事先部署好hadoop集群，因为hbase的数据需要存放在hdfs上，hadoop集群的部署后续会有一篇文章记录，本文假设hadoop集群已经部署好，分布式hbase集群需要依赖zk，并且zk可以是hbase自己托管的也可以是我们自己单独搭建的，这里我们使用自己单独搭建的zk集群，我们的hadoop集群是用的cdh的发行版，所以hbase也会使用cdh的源。

二、环境

1、软件版本

centos6

zookeeper-3.4.5+cdh5.9.0+98-1.cdh5.9.0.p0.30.el6.x86_64

hadoop-2.6.0+cdh5.9.0+1799-1.cdh5.9.0.p0.30.el6.x86_64

hbase-1.2.0+cdh5.9.0+205-1.cdh5.9.0.p0.30.el6.x86_64

2、角色

a、zk集群

10.10.20.64:2181
10.10.40.212:2181
10.10.102.207:2181

b、hbase

10.10.40.212 HMaster
10.10.20.64  HMaster
10.10.10.114 HRegionServer
10.10.40.169 HRegionServer
10.10.30.174 HRegionServer

三、部署

1、配置cdh的yum源

vim /etc/yum.repos.d/cloudera-cdh.repo
[cloudera-cdh5]
# Packages  for  Cloudera's Distribution  for  Hadoop, Version  5.4 . 4 , on RedHat or CentOS  6  x86_64
name=Cloudera's Distribution  for  Hadoop, Version  5.4 . 8
baseurl=http: //archive.cloudera.com/cdh5/redhat/6/x86_64/cdh/5.9.0/
gpgkey=http: //archive.cloudera.com/cdh5/redhat/6/x86_64/cdh/RPM-GPG-KEY-cloudera
gpgcheck= 1

[cloudera-gplextras5b2]
# Packages  for  Cloudera's GPLExtras, Version  5.4 . 4 , on RedHat or CentOS  6  x86_64
name=Cloudera's GPLExtras, Version  5.4 . 8
baseurl=http: //archive.cloudera.com/gplextras5/redhat/6/x86_64/gplextras/5.9.0/
gpgkey=http: //archive.cloudera.com/gplextras5/redhat/6/x86_64/gplextras/RPM-GPG-KEY-cloudera
gpgcheck= 1

2、安装zk集群（所有zk节点都操作）

1、安装

yum -y  install  zookeeper zookeeper-server

b、配置

vim  /etc/zookeeper/conf/zoo .cfg

tickTime=2000
initLimit=10
syncLimit=5
dataDir= /data/lib/zookeeper
clientPort=2181
maxClientCnxns=0
server.1=10.10.20.64:2888:3888
server.2=10.10.40.212:2888:3888
server.3=10.10.102.207:2888:3888
autopurge.snapRetainCount=3
autopurge.purgeInterval=1

mkdir  -p  /data/lib/zookeeper   #建zk的dir目录

echo  1 > /data/lib/zookeeper/myid   #10.10.20.64上操作
echo  2 > /data/lib/zookeeper/myid   #10.10.40.212上操作
echo  3 > /data/lib/zookeeper/myid   #10.10.102.207上操作

c、启动服务

 /etc/init .d /zookeeper-server  start

3、安装配置hbase集群

a、安装

yum -y  install  hbase hbase-master         #HMaster节点操作
yum -y  install  hbase hbase-regionserver   #HRegionServer节点操作

b、配置（所有base节点操作）

vim  /etc/hbase/conf/hbase-site .xml

"1.0" ?>
type = "text/xsl"  href= "configuration.xsl" ?>


        hbase.zookeeper.quorum< /name >
        10.10.20.64:2181,10.10.40.212:2181,10.10.102.207:2181< /value >
    < /property >

        hbase.zookeeper.property.clientPort< /name >
        2181< /value >
    < /property >

        hbase.zookeeper.property.dataDir< /name >
        /data/lib/zookeeper/ < /value >
    < /property >

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

        hbase.cluster.distributed< /name >
        true < /value >
     集群的模式，分布式还是单机模式，如果设置成 false 的话，HBase进程和Zookeeper进程在同一个JVM进程
     < /description >
    < /property >
< /configuration >

echo  "export HBASE_MANAGES_ZK=false"  >> /etc/hbase/conf/hbase-env .sh
#设置hbase使用独立的zk集群

vim  /etc/hbase/conf/regionservers
ip-10-10-30-174.ec2.internal
ip-10-10-10-114.ec2.internal
ip-10-10-40-169.ec2.internal
#添加HRegionServer的主机名到regionservers，我没有在/etc/hosts下做主机名的映射，直接用了ec2的默认主机名

c、启动服务

/etc/init .d /hbase-master  start        #HMaster节点操作
/etc/init .d /hbase-regionserver  start  #HRegionServer节点操作

4、验证

a、验证基本功能

[root@ip-10-10-20-64 ~] # hbase  shell

hbase(main):004:0>

b、验证HA功能

1、hbase默认的web管理端口是60010，两个HMaster谁先启动谁就是主active节点，10.10.40.212先启动，10.10.20.64后启动，web截图如下：

2、停止10.10.40.212的HMaster进程，查看10.10.20.64是否会提升为master

/etc/init .d /hbase-master  stop
