1 环境软件简介
hadoop2.6
zookeeper 3.3.6
openSUSE 操作系统
前提：hadoop 已经安装完毕~
2 （1）官网下载zookeeper https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.3.6/
（2）# tar xzvf zookeeper-3.3.6.tar.gz
#sudo mv zookeeper-3.3.6 /usr/local/
#cd /usr/local/zookeeper-3.3.6/
# cp conf/zoo_sample.cfg conf/zoo.cfg
#vi conf/zoo.cfg
内容如下：
# 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.
dataDir=/usr/local/zookeeper-3.3.6/var/data
dataLogDir=/usr/local/zookeeper-3.3.6/var/datalog
# the port at which the clients will connect
clientPort=2181
server.1=master:2888:3888
server.2=slave01:2888:3888
#server.3=slave02:2888:3888
（3）创建文件夹和文件
#mkdir /usr/local/zookeeper-3.3.6/var/data
#mkdir /usr/local/zookeeper-3.3.6/var/datalog
# vi /usr/local/zookeeper-3.3.6/var/data/myid
内容是：1
备注：如果是master机器 内容是1 如果是slave01机器，内容是2，内容和配置文件的server.1=master:2888:3888 server.2=slave01:2888:3888 是匹配的,server.x=机器主机名：端口：端口
（4）配置一下环境变量
#sudo vi /etc/profile
内容如下：
export ZOOKEEPER_HOME=/usr/local/zookeeper-3.3.6
export PATH=$ZOOKEEPER_HOME/bin:$ZOOKEEPER_HOME/conf:$PATH
（5）安装完成
3 同样配置，在slave01机上安装，注意myid文件的内容不一致；
4 测试：
（1）master机器上运行 # /usr/local/zookeeper-3.3.6/bin/zkServer.sh start
(2) 查看状态 #/usr/local/zookeeper-3.3.6/bin/zkServer.sh status
（3）slave01机器上运行 # /usr/local/zookeeper-3.3.6/bin/zkServer.sh start
（4）slave01机器上运行# /usr/local/zookeeper-3.3.6/bin/zkCli.sh -server master:2181
备注：master和slave01机器上的zkServer.sh 应该都启动，zoo.cfg配置了几台机器，就应该全部启动服务，否则会报错：
Unable to read additional data from server sessionid 0x0, likely server has closed socket, closing socket connection and attempting reconnect
以上，zookeeper安装告一段落~~
hbase的安装等下一篇吧
