hadoop2.x集群zookeepe集群的搭建

下载安装

配置环境变量
/etc/profile
这里 的安装的路径要写自己的

export ZK_HOME=/usr/local/zookeeper-3.4.7/
export PATH=$PATH:$JAVA_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$ZK_HOME/bin

更新配置

source  /etc/profile

随便的进入一个目录，看是否可以补全zkS。。。。.sh

进入zookeeper的安装目录找到conf目录下的
创建zoo.cfg 加入如下的内容！ 这里的目录我们要手动得创建，要不然会报错！

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
initLimit=5
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=2
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=/data/hadoop/zookeeperdata
# the port at which the clients will connect
clientPort=2181


server.1=hadoop01:2888:3888
server.2=hadoop02:2888:3888
server.3=hadoop03:2888:3888


# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1

使用ssh的认证和scp的远程的分发功能

 scp  -r  /usr/local/（zookeeper）（zookeeper的安装目录）  hadoop02:/usr/local/
  scp  -r  /usr/local/（zookeeper）（zookeeper的安装目录）  hadoop03:/usr/local/

在每台的zookeeper的临时存放的目录下的创建myid

server.1=hadoop01:2888:3888
server.2=hadoop02:2888:3888
server.3=hadoop03:2888:3888

根据上面的配置id
在hadoop01:中 ：echo 1 >> /data/hadoop/zookeeperdata/myid
在hadoop02: 中：echo 2 >> /data/hadoop/zookeeperdata/myid
在hadoop03: 中：echo 3 >> /data/hadoop/zookeeperdata/myid

启动zookeeper的命令

zkServer.sh  start   

查看zookeeper的各个节点的状态

zkServer.sh  status

jps

成功的结果：

可以使用运程登入功能：
zk.Cli.sh 名字（不加的话是登入当前的窗口）

使用quit退出！
