Zookeeper伪分布式集群搭建
- 描述
伪分布式集群就是在一台机器部署多个zk应用，部署之前服务器需要有jdk环境 java -version可以显示相关java信息才可以进行zookeeper搭建
二、步骤
>第一步下载好zookeeper-3.4.9.tar.gz
>然后解压tar zxvf zookeeper-3.4.9.tar.gz
>进入zk中的conf目录下输入cp zoo-sample.cfg zoo1.cfg cp zoo-sample.cfg zoo2.cfg、cp zoo-sample.cfg zoo3.cfg
>分别对zoo1、2、3文件进行编辑
| # 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=/apps/servers/data/d_1 dataLogDir=/apps/servers/logs/logs_1 # the port at which the clients will connect clientPort=2181 #不同zoo.cfg修改自己的属性和端口号 # 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 server.1=localhost:2187:2887 server.2=localhost:2188:2888 server.3=localhost:2189:2889

>修改之后分别创建data目录和日志目录
| mkdir /apps/servers/data/d_1 Mkdir /apps/servers/data/d_1 mkdir /apps/servers/data/d_1
mkdir /apps/servers/logs/logs_1 mkdir /apps/servers/logs/logs_1 mkdir /apps/servers/logs/logs_1
echo "1" > /apps/servers/data/d_1/myid echo "2" >/apps/servers/data/d_2/myid echo "3" >/apps/servers/data/d_3/myid |
>进入bin目录下输入命令 分别进行启动
| zkServer.sh start ../conf/zoo1.cfg zkServer.sh start ../conf/zoo2.cfg zkServer.sh start ../conf/zoo3.cfg
|
通过命令检测是否成功：
注意防火墙和配置是否成功，这个是部署成功的关键
| zkServer.sh status或者zkCli.sh -server localhost:2181, localhost:2182, localhost:2183 是否可以连接成功 如果不能连接上查看下错误日志.
