Step1:首先给Linux上传ZooKeeper安装包,然后解压;

Step2:

进入到你所安装的包的路径里面,进入conf配置文件的目录,把zoo_sample.cfg改成zoo.cfg

修改conf/zoo.cfg

# 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=/root/zkdata

# the port at which the clients will connect

clientPort=2181

# Set to "0" to disable auto purge feature

#autopurge.purgeInterval=1

server.1=hadoop1:2888:3888

server.2=hadoop2:2888:3888

server.3=hadoop3:2888:3888

step3:

配置文件修改完后,将安装包拷贝给hadoop2 和 hadoop3

 

接着,到hadoop1上,新建数据目录/root/zkdata,并在目录中生成一个文件myid,内容为1

接着,到hadoop2上,新建数据目录/root/zkdata,并在目录中生成一个文件myid,内容为2

接着,到hadoop3上,新建数据目录/root/zkdata,并在目录中生成一个文件myid,内容为3


最后在bin目录里面的zkServer.sh启动集群。
