ubuntu 16.04安装zookeeper

搭建环境

1. ubuntu 16.04 LTS
2. zookeeper-3.5.1-alpha
3. dubbo 调用

搭建过程

使用官方源码包进行安装

1. 资源准备

   • zookeeper-3.5.1-alpha.tar.gz 源码包

   • 官方稳定版下载地址http://apache.fayea.com/zookeeper/

2. 开始安装

   1. 解压压缩包到指定目录

      tar -zxvf zookeeper-3.5.1-alpha.tar.gz -C /home/zhoudazhuang/local/

   2. 使用第一步解压的源码包路径，cd /home/zhoudazhuang/local/zookeeper-3.5.1-alpha/conf 拷贝一份zoo_sample.cfg ，并命名为zoo.cfg

   3. 编辑zoo.cfg

      vim zoo.cfg

      主要修改这几个地方：

      - 增加dataDir和dataLogDir节点（目录自己创建并指定，作为数据存储目录和日志文件目录，很有用），增加配置如下：```dataDir=/home/strong/usr/local/zookeeper-3.5.1-alpha/data                dataLogDir=/home/strong/usr/local/zookeeper-3.5.1-alpha/logs```- 指定server地址    ```server.1=172.16.64.125:2888:3888```    *注：server.id=hostname:port:port。第一个端口用于集合体中的 follower 以侦听 leader；第二个端口用于 Leader 选举。第一个hostname即为本服务器地址*完整配置如下： 

      # The number of milliseconds of each ticktickTime=2000# The number of ticks that the initial # synchronization phase can takeinitLimit=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.dataDir=/home/strong/usr/local/zookeeper-3.5.1-alpha/datadataLogDir=/home/strong/usr/local/zookeeper-3.5.1-alpha/logs# the port at which the clients will connectclientPort=2181server.1=172.16.64.125:2888:3888# 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

   4. 在上一步设置的data目录中新建文件mydata,并填入上一步中配置的server.1中的数字，我这里是1,这里相当于是编了号的服务器，有多台可参考此配置。

   5. 在系统变量path中加入zookeeper （此处可省略）
      export ZOOKEEPER_HOME=/home/hadooptest/zookeeper-3.4.3
PATH=$ZOOKEEPER_HOME/bin:$PATH

   6. zookeeper服务的启动与客户端的连接（调用命令在zookeeper的bin文件夹）

      • zkServer.sh start

      • zkCli.sh -server 172.16.64.125:2181(此处我在172.16.64.111中客户端对服务端进行调用)
