#    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

<table style="width:568px;"> 
 <tbody> 
 <tr> 
 <td style="vertical-align:top;width:426.1pt;"> # 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 &nbsp; </td> 
 </tr> 
 </tbody> 
</table>

<table style="width:568px;"> 
 <tbody> 
 <tr> 
 <td style="vertical-align:top;width:426.1pt;"> mkdir /apps/servers/data/d_1 Mkdir /apps/servers/data/d_1 mkdir /apps/servers/data/d_1 &nbsp; mkdir /apps/servers/logs/logs_1 mkdir /apps/servers/logs/logs_1 mkdir /apps/servers/logs/logs_1 &nbsp; echo "1" &gt; /apps/servers/data/d_1/myid echo "2" &gt;/apps/servers/data/d_2/myid echo "3" &gt;/apps/servers/data/d_3/myid </td> 
 </tr> 
 </tbody> 
</table>

>进入bin目录下输入命令 分别进行启动

<table style="width:568px;"> 
 <tbody> 
 <tr> 
 <td style="vertical-align:top;width:426.1pt;"> zkServer.sh start ../conf/zoo1.cfg zkServer.sh start ../conf/zoo2.cfg zkServer.sh start ../conf/zoo3.cfg &nbsp; </td> 
 </tr> 
 </tbody> 
</table>

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

<table style="width:568px;"> 
 <tbody> 
 <tr> 
 <td style="vertical-align:top;width:426.1pt;"> 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. <img alt="" height="229" src="https://img-blog.csdnimg.cn/20181120215448883.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3o3ODU0OTUyOTU=,size_16,color_FFFFFF,t_70" width="447"> &nbsp; &nbsp; </td>
