• Ubuntu18.04 搭建zookeeper单机版集群


    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 '
    ZK_HOME=/opt/zk
    PATH=$PATH:$ZK_HOMEin
    ' >> /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 acknowledgement
    syncLimit=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/data
    dataLogDir=/data/zk1/logs
    
    # the port at which the clients will connect
    clientPort=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:2888:3888
    server.2=bogon:2889:3889
    server.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.cfg
    done
