【Dubbo菜鸟教程】2、注册中心zookeeper安装

来源:互联网 发布:c语言截断 编辑:程序博客网 时间:2024/05/19 23:09

掌握了dubbo的使用,接下来选择一款注册中心,一般人都会使用zookeeper,也建议使用zookeeper

dubbo支持多种类型的注册中心: 

 Multicast注册中心 

 Zookeeper注册中心

 Redis注册中心 

Simple注册中心

其实我也是菜鸟,所以只对Zookeeper熟悉一些,关于其他的就不多说了,百度搜索一大堆在这里就讲讲Zookeeper的使用:

我这里在window上安装zookeeper,

第一步下载zookeeper

下载地址:https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/ 可以在里面下载,这是免安装的,只需要修改配置文件就可以使用,

打开zookeeper文件夹下的conf文件夹,修改zoo_sample.cfg为 zoo.cfg,然后打开修改里面配置文件

# 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=E:\\work\\zookeeper-3.5.2-alpha.tar\\zookeeper-3.5.2-alpha\\datadataLogDir=E:\\work\\zookeeper-3.5.2-alpha.tar\\zookeeper-3.5.2-alpha\\log# the port at which the clients will connectclientPort=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

这个配置完后剩下就配置环境变量,首先要把JAVA_HOME配置好

新增环境变量:ZOOKEEPER_HOME   变量值:E:\work\zookeeper-3.5.2-alpha.tar\zookeeper-3.5.2-alpha(变量值要根据你下的zookeeper包的放置位置)

再在系统变量path最后添加: ;%ZOOKEEPER_HOME%/bin; %ZOOKEEPER_HOME%/conf


然后运行zookeeper目录下bin目录下的zkServer.cmd,然后会打开一个黑窗口,启动成功后不要关闭窗口,然后下载我在网上找的demo,demo其实很简单,

把两个项目的配置文件中注册中心地址都改为本地ip,先运行生产端,然后再运行客户端,
