1 環境軟件簡介
hadoop2.6
zookeeper 3.3.6
openSUSE 操作系統
前提：hadoop 已經安裝完畢~
2 （1）官網下載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
內容如下：
# 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）創建文件夾和文件
#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
內容是：1
備註：如果是master機器 內容是1 如果是slave01機器，內容是2，內容和配置文件的server.1=master:2888:3888 server.2=slave01:2888:3888 是匹配的,server.x=機器主機名：端口：端口
（4）配置一下環境變量
#sudo vi /etc/profile
內容如下：
export ZOOKEEPER_HOME=/usr/local/zookeeper-3.3.6
export PATH=$ZOOKEEPER_HOME/bin:$ZOOKEEPER_HOME/conf:$PATH
（5）安裝完成
3 同樣配置，在slave01機上安裝，注意myid文件的內容不一致；
4 測試：
（1）master機器上運行 # /usr/local/zookeeper-3.3.6/bin/zkServer.sh start
(2) 查看狀態 #/usr/local/zookeeper-3.3.6/bin/zkServer.sh status
（3）slave01機器上運行 # /usr/local/zookeeper-3.3.6/bin/zkServer.sh start
（4）slave01機器上運行# /usr/local/zookeeper-3.3.6/bin/zkCli.sh -server master:2181
備註：master和slave01機器上的zkServer.sh 應該都啓動，zoo.cfg配置了幾臺機器，就應該全部啓動服務，否則會報錯：
Unable to read additional data from server sessionid 0x0, likely server has closed socket, closing socket connection and attempting reconnect
以上，zookeeper安裝告一段落~~
hbase的安裝等下一篇吧
