一台电脑启动三个虚拟机比较折腾，这里就用一台虚拟机模拟一下zk集群。

1.后台下载安装包到 /opt目录

sudo wget -b http://archive.apache.org/dist/zookeeper/zookeeper-3.4.9/zookeeper-3.4.9.tar.gz \-o /opt/archive/zookeeper.download.log -P /opt

解压、链接、配置环境变量

tar -zxf /opt/zookeeper-3.4.9.tar.gz -C /opt;ln -s /opt/zookeeper-3.4.9 /opt/zk;echo -e '\nZK_HOME=/opt/zk\nPATH=\$PATH:\$ZK_HOME\bin\n' >> /etc/profile;

2.创建数据及日志目录并修改权限

# 同时为创建3*2=6个目录sudo mkdir /data/{zk1,zk2,zk3}/{data,logs}# 修改权限为当前用户所有sudo chown -R $USER:$GROUPS /data/{zk1,zk2,zk3}

3.复制并修改配置文件

cp /opt/zk/conf/zoo_sample.cfg /data/zk1/zoo.cfg

4.配置文件

# The number of milliseconds of each tick# 心跳间隔tickTime=2000# The number of ticks that the initial # synchronization phase can take# 初始同步阶段的心跳间隔initLimit=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.# 存储快照的目录，不要使用/tmp目录dataDir=/data/zk1/datadataLogDir=/data/zk1/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# 心跳端口，数据端口;选举完成后，每个节点打开数据端口;只有主节点打开心跳端口，接受心跳数据# server.N 和 myid 是对应的server.1=bogon:2888:3888server.2=bogon:2889:3889server.3=bogon:2890:3890

　　

5.批量操作脚本

for zk in {1,2,3}do    myid=/data/zk${zk}/data/myid    if [ ! -e "$myid" ];then        echo $zk > $myid    fi    zkServer.sh $1 /data/zk${zk}/zoo.cfgdone
