安装

步骤一：上传zookeeper-3.3.6.tar.gz
步骤二：解压到指定的文件夹中（本人解压到/usr/local/soft下）
步骤三：安装目录下conf/zoo_sample.cfg重命名zoo.cfg

# 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=/usr/local/soft/zookeeper-3.3.6/data  
dataLogDir=/usr/local/soft/zookeeper-3.3.6/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  

启动

1. 启动ZK服务: sh bin/zkServer.sh start
2. 停止ZK服务: sh bin/zkServer.sh stop
3. 重启ZK服务: sh bin/zkServer.sh restart
4. 查看ZK服务状态: sh bin/zkServer.sh status

dubbo-admin

简介

配置

步骤一：下载dubbo地址
步骤二：进入下载源码的dubbo-admin下，进行打包处理

mvn package -Dmaven.skip.test=true
注意：此处有可能打包失败，我的解决方式是翻墙重新打包！

步骤三：修改tomcat的端口，记得一定要改！！！

步骤四：将第二步中打的dubbo-admin-2.5.8.war放入到tomcat的webapps目录中。

步骤五：启动tomcat服务器（此时如果不是本地的zookeeper，会报错）

步骤六：修改\webapps\dubbo-admin-2.5.8\WEB-INF文件夹下的dubbo.properties文件。

dubbo.registry.address=zookeeper://39.106.44.170:2181     （注意：此处是zookeeper协议）
dubbo.admin.root.password=root
dubbo.admin.guest.password=guest

步骤七：重新启动tomcat服务器

步骤八：访问地址：http://localhost:9080/dubbo-admin-2.5.8/
