Zookeeper集群环境装配

Zookeeper集群环境安装

1.集群机器配置

192.168.1.251

2.上述机器上分别安装Hadoop的集群，不在累述。其中namenode为master，其他为slave

3.下载zookeeper-3.3.5.tar.gz，下面以namenode为例

解压到/home/wilian目录下 tar -xzvf ?zookeeper-3.3.5.tar.gz

4.设置环境变量

export ZOOKEEPER_HOME=/home/wilian/zookeeper-3.3.5

export?PATH=$PATH:$ZOOKEEPER_HOME/bin

5.配置zoo.conf文件

在${ZOOKEEPER_HOME}/conf目录下 执行 cp?zoo_sample.cfg zoo.cfg

修改该文件 如下：

[wilian@localhost conf]$ cat zoo.cfg# The number of milliseconds of each ticktickTime=2000# The number of ticks that the initial # synchronization phase can takeinitLimit=10# The number of ticks that can pass between # sending a request and getting an acknowledgementsyncLimit=5# the directory where the snapshot is stored.dataDir=/home/wilian/zookeeper-3.3.5/data# the port at which the clients will connectclientPort=2181dataLogDir=/home/wilian/zookeeper-3.3.5/logserver.1=192.168.1.250:2888:3888server.2=192.168.1.237:2888:3888server.3=192.168.1.251:2888:3888

5.配置myid文件

在${ZOOKEEPER_HOME}?/data创建myid文件

内容为zoo.conf中主机对应的ID

[wilian@localhost data]$ cat myid?

1

6.将zookeeper-3.3.5文件夹传输到其他机器上

scp -r?zookeeper-3.3.5 datanode1:/home/wilian?

scp -r?zookeeper-3.3.5 datanode2:/home/wilian?

7.按照步骤5修改myid文件，并按照步骤4设置每台机器的环境变量

8.依次启动每个机器的zookeeper，速度要快

bin/zkServer.sh start

9.运行bin/zkServer.sh status检查启动状况或用jps检查会发现多了QuorumPeerMain进程
