1、下载
wget http://mirror.bit.edu.cn/apache/zookeeper/stable/zookeeper-3.4.6.tar.gz
2、解压安装
tar -xzvf zookeeper-3.4.6.tar.gz
3、设置相关环境变量
export JAVA_HOME=/opt/jdk1.6.0_45
export ZOOKEEPER_HOME=/home/sankuai/heyutao/zookeeper-3.4.6
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$ZOOKEEPER_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
4、在每台机器上配置
4.1 配置文件
进入zookeeper-3.4.6/conf：
$:cp zoo_sample.cfg zoo.cfg
$:vim 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=/home/sankuai/heyutao/zookeeper-3.4.6/data dataLogDir=/home/sankuai/heyutao/zookeeper-3.4.6/logs # the port at which the clients will connect clientPort=2181 server.1=192.168.4.114:2888:3888 server.2=192.168.22.132:2888:3888 server.3=192.168.22.124:2888:3888 # 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
4.2 myid的文件
接下来在dataDir所指定的目录下创建一个文件名为myid的文件，文件中的内容只有一行，为本主机对应的id值，也就是上图中server.id中的id。例如：在服务器1中的myid的内容应该写入1。
5、启动
在ZooKeeper集群的每个结点上，执行启动ZooKeeper服务的脚本，如下所示：
zkServer.sh start
jps，其中，QuorumPeerMain是zookeeper进程，启动正常。
6、查看状态
zkServer.sh status
7、客户端链接
bin/zkCli.sh -server 192.168.4.114:2181
