windows安装Zookeeper

1.zookeeper下载

zookeeper下载地址 ：http://archive.apache.org/dist/zookeeper/

下载后解压到自己想要的位置，zookeeper是免安装的。这时我们安装好了进行下面配置

• 在zookeeper目录下创建data、log两个文件夹，可以先备份一份zoo_sample.cfg，再把conf目录下的zoo_sample.cfg改名成zoo.cfg，并修改zoo.cfg的dataDir目录

• zoo.cfg文件修改内容

# 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=/tmp/zookeeper
#修改内容
dataDir=D:\\zookeeper-3.4.13\\data 
dataLogDir=D:\\zookeeper-3.4.13\\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.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

2.环境变量配置

需要配置一下环境变量才可以运行zookeeper（基于Windows已经配置过JAVA_HOME并且配置正确)

• 新增环境变量：ZOOKEEPER_HOME
• 变量值： D:\zookeeper-3.4.13（变量值要根据zookeeper的放置位置）

• 再在系统变量path最后添加：%ZOOKEEPER_HOME%\bin;%ZOOKEEPER_HOME%\conf; 并保存就可以了

3.验证是否安装成功

点击bin目录下的zkServer.cmd 这时候出现下面的提示就说明配置成功了。

注意 ：这个窗口不要关闭！让注册中心服务一直运行。

4.项目dubbo配置

依赖引入

<!--dubbo--><dependency><groupId>org.apache.dubbo</groupId><artifactId>dubbo</artifactId><version>2.7.7</version><exclusions><exclusion><groupId>io.netty</groupId><artifactId>netty-all</artifactId></exclusion></exclusions></dependency><dependency><groupId>io.netty</groupId><artifactId>netty-all</artifactId><version>4.1.50.Final</version></dependency><!--zookeeper--><dependency><groupId>org.apache.zookeeper</groupId><artifactId>zookeeper</artifactId><version>3.4.14</version><exclusions><exclusion><groupId>org.slf4j</groupId><artifactId>slf4j-api</artifactId></exclusion><exclusion><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId></exclusion><exclusion><groupId>io.netty</groupId><artifactId>netty</artifactId></exclusion><exclusion><groupId>log4j</groupId><artifactId>log4j</artifactId></exclusion></exclusions></dependency><dependency><groupId>org.apache.curator</groupId><artifactId>curator-recipes</artifactId><version>4.2.0</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>4.3.5.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId></dependency>

消费者和提供者的配置

消费者application.properties文件配置

# zookeeper
#配置dubbo端口号
dubbo.protocol.port=27280 
dubbo.config.location=classpath:dubbo-consumer.xml
dubbo.registry.address=127.0.0.1:2181
dubbo.application.name=consumer

dubbo-consumer.xml文件
