Hbase集群搭建（一）

在此之前，已经搭建完毕hadoop2.7.3的集群，接下来搭建Hbase1.2.4

先安装zookeeper

解压 sudo tar -zxvf zookeeper-3.4.9.tar.gz

切换到root，编辑/etc/profile，增加环境变量

export ZOOKEEPER_HOME=/Bigdata/zookeeper
export PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$ZOOKEEPER_HOME/bin:$ZOOKEEPER_HOME/conf

进入到zookeeper的conf目录下，mv zoo_sample.cfg zoo.cfg，修改配置文件

# 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=/Bigdata/zookeeper/var/data
dataLogDir=/Bigdata/zookeeper/var/log
# the port at which the clients will connect
clientPort=2181
server.1=namenode:2888:3888
server.2=datanode1:2888:3888
server.3=datanode2:2888:3888
server.4=datanode3:2888:3888
# 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

创建var目录下的文件夹，data和log

在data文件夹下创建myid文件，并写入对应的id数字

启动zookeeper

hadoop@namenode:/Bigdata$ zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /Bigdata/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... /Bigdata/zookeeper/bin/zkServer.sh: line 140: ./zookeeper.out: Permission denied
STARTED

上面产生了访问权限错误，从网上查找原因，增加环境变量export ZOO_LOG_DIR，问题搞定

运行jps命令，能看到QuorumPeerMain
