Zookeeper之集群搭建-yellowcong

之前讲的都是单机的一个zookeeper的安装，这次我们玩集群的操作,通过脚本完成数据的启动，通过脚本来管理zookeeper的集群

架构设计

ip 安装目录 存储目录 日志目录 192.168.66.100:2181 /usr/local/zookeeper/zookeeper1 /tmp/zookeeper1/data/ /tmp/zookeeper1/logs 192.168.66.100:2182 /usr/local/zookeeper/zookeeper2 /tmp/zookeeper2/data/ /tmp/zookeeper2/logs 192.168.66.100:2183 /usr/local/zookeeper/zookeeper3 /tmp/zookeeper3/data/ /tmp/zookeeper3/logs

zookeeper安装

1 zoo.cfg配置

#官方的包wget http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.4.10/zookeeper-3.4.10.tar.gz#我七牛的安装包wget http://yellowcong.qiniudn.com/zookeeper-3.4.10.tar.gz #解压tar -zxvf zookeeper-3.4.10.tar.gz#修改配置文件cp zoo_sample.cfg zoo.cfg#修改配置文件vim zoo.cfg

以下是配置文件，自己做的时候，需要注意修改dataDir和dataLogDir还有端口配置

# synchronization phase can takeinitLimit=10# The number of ticks that can pass between# sending a request and getting an acknowledgementsyncLimit=5# the directory where the snapshot is stored.# do not use /tmp for storage, /tmp here is just# example sakes.#数据存储目录dataDir=/tmp/zookeeper1/data#日志地址dataLogDir=/tmp/zookeeper1/logs# the port at which the clients will connectclientPort=2181# 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#配置集群，#server.1 前面这个1 需要在$dataDir 目录建立myid文件写上这个id#127.0.0.1 这个ip 如果你是多个机器，那就注意点，写自己机器的ip#2222 第一个2222是各个子节点的数据交流端口#2225 第二个端口是用于竞选，当某个节点挂掉了，选择主节点server.1=127.0.0.1:2222:2225server.2=127.0.0.1:3333:3335server.3=127.0.0.1:4444:4445

2 目录建立

建立目录的节点，同时需要添加myid的号 ,注意每个节点的id和节点的myid文件不能搞错了，刚刚我就搞错了，我说咋一个节点咋都起不来啊。

---------------------节点一------------------------#创建日志和存储目录mkdir -p /tmp/zookeeper1/data /tmp/zookeeper1/logs#添加pidecho 1 > /tmp/zookeeper1/data/myid ---------------------节点二------------------------mkdir -p /tmp/zookeeper2/data /tmp/zookeeper2/logsecho 2 > /tmp/zookeeper2/data/myid ---------------------节点三------------------------mkdir -p /tmp/zookeeper3/data /tmp/zookeeper3/logsecho 3 > /tmp/zookeeper3/data/myid #查看myid文件信息，一定要和当前节点对应上cat /tmp/zookeeper1/data/myid cat /tmp/zookeeper2/data/myid cat /tmp/zookeeper3/data/myid 

目录结构

3 启动服务

#建立脚本启动，这样省事vim zookeeper.sh#给执行权限chmod +x zookeeper.sh

zookeeper.sh脚本

#!/bin/bashSERVER1="/usr/local/zookeeper/zookeeper1/zookeeper-3.4.10/bin/zkServer.sh"SERVER2="/usr/local/zookeeper/zookeeper2/zookeeper-3.4.10/bin/zkServer.sh"SERVER3="/usr/local/zookeeper/zookeeper3/zookeeper-3.4.10/bin/zkServer.sh"case $1 instart)        echo "start zookeeper"        sh $SERVER1 start        sh $SERVER2 start        sh $SERVER3 start        ;;stop)        echo "stop zookeeper"        sh $SERVER1 stop        sh $SERVER2 stop        sh $SERVER3 stop        ;;restart)        echo "restart zookeeper"        sh $SERVER1 restart        sh $SERVER2 restart        sh $SERVER3 restart        ;;status)        echo "zookeeper info"        sh $SERVER1 status        sh $SERVER2 status        sh $SERVER3 status        ;;*)        echo "./zookeeper.sh start|stop|restart"        exit 1        ;;esacexit 0

脚本截图，这个地方有简单的启动信息

4 设定开机启动

vim /etc/rc.localsu - root -c '/usr/local/zookeeper/zookeeper.sh start'

开机如果没有生效，请参考我的另一篇文章:
