zookeeper集群（一、搭建集群）

服务器三台：

10.0.3.114

10.0.3.120

10.0.3.156

分别在三台机器上安装了zookeeper-3.4.6；

三台机器上绑定hosts：

10.0.3.114 zookeeper-1

10.0.3.120 zookeeper-2

10.0.3.156 zookeeper-3

zookeeper集群的机器是有顺序的；

一、10.0.3.114；zookeeper的根目录；

1，进入conf目录：

vi 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=/data/server/zookeeper-3.4.6/zookeeper-data/
# the port at which the clients will connect
clientPort=2181

server.1=zookeeper-1:2888:3888
server.2=zookeeper-2:2888:3888
server.3=zookeeper-3:2888:3888

# 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

修改dataDir;

添加

server.1=zookeeper-1:2888:3888

server.2=zookeeper-2:2888:3888

server.3=zookeeper-3:2888:3888

2，进入dataDir的目录下；

创建myid

文件内容写入1；

myid里对应的是机器的编号，server.1就写入1

二、10.0.3.120；10.0.3.156；

步骤相同；myid不同而已；

可能会遇到的问题；

当你启动第一台的时候；

./zkServer.sh status

JMX enabled by default
Using config: /data/server/zookeeper-3.4.6/bin/../conf/zoo.cfg
Error contancting service.It is probably not running.

这里不用担心，因为当你三台全部启动完成就可以啦！
