获取源码
下载
官网：https://zookeeper.apache.org/releases.html#download
解压
# wget http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.4.13/zookeeper-3.4.13.tar.gz
# tar xf zookeeper-3.4.13.tar.gz
# mv zookeeper-3.4.13 /usr/local/
# mv /usr/local/zookeeper-3.4.13 /usr/local/zookeeper
第一台机器配置zookeeper
创建数据目录
root@hadoop-master:/usr/local/zookeeper# mkdir data
修改配置zoo.cfg
root@hadoop-master:/usr/local/zookeeper/conf# cp zoo_sample.cfg zoo.cfg
在那个节点内就将那个节点的ip改为0.0.0.0
在那个节点内就将那个节点的ip改为0.0.0.0
root@hadoop-master:/usr/local/zookeeper/conf# cat zoo.cfg
# The number of milliseconds of each tick
tickTime=2000
dataDir=/var/data/zookeeper
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.

server.1=0.0.0.0:2888:3888
server.2=192.168.0.170:2888:3888
server.3=192.168.0.166:2888:3888
创建myid文件
root@hadoop-master:/usr/local/zookeeper/data# touch myid
root@hadoop-master:/usr/local/zookeeper/data# echo "1">>myid
拷贝至node节点
root@hadoop-master:/usr/local/zookeeper/data# scp -r /usr/local/zookeeper root@192.168.0.170:/usr/local/
其他机器节点配置
修改配置zoo.cfg
在那个节点内就将那个节点的ip改为0.0.0.0
vim zoo.cfg
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1
server.1=192.168.0.169:2888:3888
server.2=0.0.0.0:2888:3888
server.3=192.168.0.166:2888:3888
myid值为2
依次类推
root@hadoop-slave1:~# cd /usr/local/zookeeper/data
root@hadoop-slave1:/usr/local/zookeeper/data# echo "2">myid
防火墙
开放 or 卸载掉
过程 略
启动
所有节点都需要启动
root@hadoop-master:/usr/local/zookeeper/data# /usr/local/zookeeper/bin/zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
状态检查
# /usr/local/zookeeper/bin/zkServer.sh status
