輕鬆上手ZooKeeper集羣搭建

Step1：首先給Linux上傳ZooKeeper安裝包，然後解壓；

Step2：

進入到你所安裝的包的路徑裏面，進入conf配置文件的目錄，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:

配置文件修改完後，將安裝包拷貝給hadoop2 和 hadoop3

 

接着，到hadoop1上，新建數據目錄/root/zkdata，並在目錄中生成一個文件myid，內容爲1

接着，到hadoop2上，新建數據目錄/root/zkdata，並在目錄中生成一個文件myid，內容爲2

接着，到hadoop3上，新建數據目錄/root/zkdata，並在目錄中生成一個文件myid，內容爲3

最後在bin目錄裏面的zkServer.sh啓動集羣。
