zookeeper集羣搭建

1.下載安裝包

安裝包

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

解壓

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

首先複製一份原來的配置文件
cp zoo_sample.cfg zoo.cfg


# The number of milliseconds of each tick
tickTime=2000 #心跳的單元時間 2s
# The number of ticks that the initial 
# synchronization phase can take
initLimit=10 #follower和leader開始鏈接的最長時間 20s
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5 #follower和leader同步的最長時間 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所在目錄，數據目錄
# the port at which the clients will connect
clientPort=2181 #服務端口
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表明有3臺機器 123要同myid文件對應；
#2881，2882，2883是數據同步端口；
#3881，3882，3883是選舉端口

修改三份配置

建立myid文件

3.啓動

分別執行

./bin/zkServer.sh start

查看狀態

./bin/zkServer.sh status

4.命令行訪問

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

簡單腳本

#/usr/bin/bash

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