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/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 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=E:\\work\\zookeeper-3.5.2-alpha.tar\\zookeeper-3.5.2-alpha\\data
dataLogDir=E:\\work\\zookeeper-3.5.2-alpha.tar\\zookeeper-3.5.2-alpha\\log
# the port at which the clients will connect
clientPort=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/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,
demo地址如下:
