1.hadoop环境安装
hbase是建立在Hadoop之上的一个NOSQL数据库，所以你得首先安装Hadoop，安装Hadoop参见http://zilongzilong.iteye.com/blog/2245547
2.zookeeper3.4.6集群安装
1，hbase regionserver 向zookeeper注册，提供hbase regionserver状态信息（是否在线）
2，hmaster启动时候会将hbase 系统表-ROOT- 加载到 zookeeper cluster，通过zookeeper cluster可以获取当前系统表.META.的存储所对应的regionserver信息。
1) 下载解压
下载zookeeper-3.4.6.tar.gz到/opt
解压tar -zxvf zookeeper-3.4.6.tar.gz
2) 配置/etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
192.168.186.234 inddb1-vip
192.168.186.235 inddb2-vip
192.168.88.22 nmsc2
192.168.88.21 nmsc1
192.168.181.66 nmsc0
3) 创建zookeeper数据文件
sudo rm -r /home/hadoop/zookeeper
cd /home/hadoop
mkdir zookeeper
4) 配置zoo.cfg
将zookeeper-3.3.4/conf目录下面的 zoo_sample.cfg修改为zoo.cfg，配置文件内容如下所示
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=/home/hadoop/zookeeper
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1
server.1=nmsc0:2888:3888
server.2=nmsc1:2888:3888
server.3=nmsc2:2888:3888
5) 远程复制分发安装文件
scp -r /opt/zookeeper-3.3.4 root@nmsc1:/opt/
scp -r /opt/zookeeper-3.3.4 root@nmsc2:/opt/
6) 设置myid必须为数字
ssh nmsc0
echo "1" > /home/hadoop/zookeeper/myid
ssh nmsc1
echo "2" > /home/hadoop/zookeeper/myid
ssh nmsc2
echo "3" > /home/hadoop/zookeeper/myid
7) 启动ZooKeeper集群
cd /opt/zookeeper-3.4.6
bin/zkServer.sh start
8) 查看单机ZooKeeper是leader还是follower
cd /opt/zookeeper-3.4.6
bin/zkServer.sh status
9) 停止ZooKeeper集群
cd /opt/zookeeper-3.4.6
bin/zkServer.sh stop
3.时间同步
注意：集群中机器时间同步很关键，时间最好相差在1秒以下，不然hbase启动会失败
方法一
安装NTP服务，参见http://wenku.baidu.com/link?url=0outiNUpCi-RzCtmWCKgqyVE0S_hyEcc3cjfbes_XHtxDN4wCh3-TXAe8YrtW1iOudzloNbMRMFe6niTS_uODhWEdPjD7MEwimib1a02FVm
方法二
我这是公司内部有时间同步的机器，直接从该机器同步数据，执行命令如下：
#从机器192.168.162.23同步系统时间
ntpdate -u 192.168.162.23
