下载zookeeper并上传到服务器

解压zookeeper并分别创建3个文件夹

解压文件复制到各个文件中,进入conf文件中，

复制文件并修改名称

mv  zoo_sample.cfg zoo.cfg

编辑zoo.cfg

# Server 2
# The number of milliseconds of each tick
# 服务器与客户端之间交互的基本时间单元（ms）
tickTime=2000

# The number of ticks that the initial 
# synchronization phase can take
# zookeeper所能接受的客户端数量
initLimit=10

# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
# 服务器与客户端之间请求和应答的时间间隔
syncLimit=5

# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
# 保存zookeeper数据，日志路径
dataDir=/opt/zookeeper-cluster/zookerper-1/data
dataLogDir=/opt/zookeeper-cluster/zookerper-1/log

# the port at which the clients will connect
# 客户端与zookeeper相互交互的端口
clientPort=2181
server.1= 127.0.0.1:2888:3888
server.2= 127.0.0.1:2889:3889
server.3= 127.0.0.1:2890:3890

#server.A=B:C:D  其中A是一个数字，代表这是第几号服务器；B是服务器的IP地址；C表示服务器与群集中的“领导者”交换信息的端口；当领导者失效后，D表示用来执行选举时服务器相互通信的端口。

# 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

在

/opt/zookeeper-cluster/zookerper-1/下创建data和log文件

进入data文件夹

vi myid 并写入1

zookeeper-1就算完成了

继续完成zookeeper-2和zookeeper-3并修改相应的位置，与zookeeper-1相似

如果是一台机器上部署集群的话，clientPort端口一定不能一样，

启动zookeeper

./opt/zookeeper-cluster/zookerper-1/bin/zkServer.sh start

./opt/zookeeper-cluster/zookerper-2/bin/zkServer.sh start

./opt/zookeeper-cluster/zookerper-3/bin/zkServer.sh start

查看状态(全部启动完了后再查看状态)

./opt/zookeeper-cluster/zookerper-1/bin/zkServer.sh status

OK，启动完成
