3.1下载zk

下载网址:https://zookeeper.apache.org/

3.2修改zk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.
dataDir=../data
#dataLogDir=../data/tlog

# 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

# the port at which the clients will connect
clientPort=2181

minSessionTimeout=5000
maxSessionTimeout=10000

server.1=127.0.0.1:28880:38880
#server.2=10.143.24.16:28880:38880
#server.3=10.143.24.17:28880:38880

3.3操作zk

启动zk./zkServer.sh start

zkClient.sh连接zk服务端,get /查看根节点下面信息

在zk中创建临时节点create -e /节点路径 节点里的内容,使用 ls /节点路径查看节点中的内容

3.4dubbo安装admin

git clone https://github.com/apache/dubbo-admin.git 将admin项目clone到本地

使用idea打开dubbo-admin工程修改其admin中的配置文件为要连的注册中心的地址,并且使用mvn clean,mvn package打包,即可看到

将打出的jar包拖出来执行java -jar dubbo-admin-0.0.1-SNAPSHOT.jar

浏览器输入http://localhost:7001/
账号root 密码root 进入管理页面
