  • zookeeper集群搭建

    一台服务其中利用不同端口搭建zookeeper集群,三个zookeeper实例,请在配置好jdk环境前提下操作

    1 将zookeeper上传到服务器。
    2 解压缩tar -zxf zookeeper-3.4.10.tar.gz
    3 在/usr/local/目录下创建一个solrcloud目录。把zookeeper解压后的文件夹复制到此目录下三份。分别命名为zookeeper1、2、3
    [root@bogon ~]# mkdir /usr/local/solrcloud
    
    [root@bogon ~]# mv zookeeper-3.4.6 /usr/local/solrcloud/zookeeper1
    
    [root@bogon ~]# cd /usr/local/solrcloud
    
    [root@bogon solrcloud]# ll
    
    total 4
    
    drwxr-xr-x. 10 1000 1000 4096 Feb 20  2014 zookeeper1
    
    [root@bogon solrcloud]# cp -r zookeeper1/ zookeeper2
    
    [root@bogon solrcloud]# cp -r zookeeper1/ zookeeper3
    
    [root@bogon solrcloud]#
    4 配置zookeeper。

    1、在每个zookeeper文件夹下创建一个data目录。

    2、在data文件夹下创建一个文件名称为myid,文件的内容就是此zookeeper的编号1、2、3

    cd zk1/data/
    touch myid
    echo 1 > myid 
    

      

    3、把每个下conf目录下的zoo_sample.cfg文件复制一份改名为zoo.cfg

    分别按如下修改配置

    zookeeper1

    # The number of milliseconds of each tick
    tickTime=2000
    # The number of ticks that the initial 
    # synchronization phase can take
    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.
    #dataDir=/tmp/zookeeper
    dataDir=/opt/SolrCloudZookeeper/zookeeper1/data
    # the port at which the clients will connect
    clientPort=2181
    server.1=192.168.10.131:2881:3881
    server.2=192.168.10.131:2882:3882
    server.3=192.168.10.131:2883:3883
    # 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

    zookeeper2

    # The number of milliseconds of each tick
    tickTime=2000
    # The number of ticks that the initial 
    # synchronization phase can take
    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.
    #dataDir=/tmp/zookeeper
    dataDir=/opt/SolrCloudZookeeper/zookeeper2/data
    # the port at which the clients will connect
    clientPort=2182
    server.1=192.168.10.131:2881:3881
    server.2=192.168.10.131:2882:3882
    server.3=192.168.10.131:2883:3883
    # 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

    zookeeper3

    # The number of milliseconds of each tick
    tickTime=2000
    # The number of ticks that the initial 
    # synchronization phase can take
    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.
    #dataDir=/tmp/zookeeper
    dataDir=/opt/SolrCloudZookeeper/zookeeper3/data
    # the port at which the clients will connect
    clientPort=2183
    server.1=192.168.10.131:2881:3881
    server.2=192.168.10.131:2882:3882
    server.3=192.168.10.131:2883:3883
    # 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

    #修改dataDir,指向data目录

    dataDir=/usr/local/solr-cloud/zookeeper03/data/

    #solr的通讯端口(集群中不能重复)

    clientPort=2184

    #第一个端口为通讯端口,第二个为投票选举端口

    server.1=192.168.31.241:2887:3887

    server.2=192.168.31.241:2888:3888

    server.3=192.168.31.241:2889:3889 

    5 启动zookeeper。

    进入zookeeper1/bin目录下。

    ./zkServer.sh start  //启动zookeeper
    ./zkServer.sh start-foreground //(可以查看启动日志,ctrl+c退出后自动关闭zookeeper) 
    
    ./zkServer.sh stop //关闭
    
    ./zkServer.sh status//查看状态
    

      

      

    状态信息如下,代表启动成功

    [root@bogon solrcloud]# zookeeper1/bin/zkServer.sh status
    
    JMX enabled by default
    
    Using config: /usr/local/solrcloud/zookeeper1/bin/../conf/zoo.cfg
    
    Mode: follower
    
    [root@bogon solrcloud]# zookeeper2/bin/zkServer.sh status
    
    JMX enabled by default
    
    Using config: /usr/local/solrcloud/zookeeper2/bin/../conf/zoo.cfg
    
    Mode: leader
    
    [root@bogon solrcloud]# zookeeper3/bin/zkServer.sh status
    
    JMX enabled by default
    
    Using config: /usr/local/solrcloud/zookeeper3/bin/../conf/zoo.cfg
    
    Mode: follower
    
    [root@bogon solrcloud]#
    配置集群统一启动批处理
    cd zookeeper01/bin
    ./zkServer.sh start
    cd ../../
    cd zookeeper02/bin
    ./zkServer.sh start
    cd ../../
    cd zookeeper03/bin
    ./zkServer.sh start
