zookeeper集群搭建

1.下载安装包

安装包

wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.6.0/apache-zookeeper-3.6.0-bin.tar.gz

解压

tar -xcf aparche-zookeeper-3.6.0-bin.tar.gz

2.修改配置

/etc/hosts配置修改

192.168.159.3 dev1.xiayu.com
192.168.159.3 dev2.xiayu.com
192.168.159.3 dev3.xiayu.com

zookeeper配置文件修改

首先复制一份原来的配置文件
cp zoo_sample.cfg zoo.cfg


# The number of milliseconds of each tick
tickTime=2000 #心跳的单元时间 2s
# The number of ticks that the initial 
# synchronization phase can take
initLimit=10 #follower和leader开始连接的最长时间 20s
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5 #follower和leader同步的最长时间 10s
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=/data/zookeeper/zk1 #myid所在目录，数据目录
# the port at which the clients will connect
clientPort=2181 #服务端口
server.1=dev1.xiayu.com:2881:3881 
server.2=dev2.xiayu.com:2882:3882
server.3=dev3.xiayu.com:2883:3883
#server.1 server.2 server.3代表有3台机器 123要同myid文件对应；
#2881，2882，2883是数据同步端口；
#3881，3882，3883是选举端口

修改三份配置

创建myid文件

3.启动

分别执行

./bin/zkServer.sh start

查看状态

./bin/zkServer.sh status

4.命令行访问

./bin/zkCli.sh -server dev1.xiayu.com:2181,dev2.xiayu.com:2182,dev3.xiayu.com:2183

简单脚本

#/usr/bin/bash

./zookeeper1/bin/zkServer.sh status
./zookeeper2/bin/zkServer.sh status
./zookeeper3/bin/zkServer.sh status
