Dubbo+ZooKeeper之旅

准备工作

根据dubbo的结构体系需要下载相关的软件

下载

zookeeper——注册中心(Registry)

zookeeper官网下载地址：https://zookeeper.apache.org/releases.html#download

apache-zookeeper-3.6.0-bin.tar.gz

Dubbo+ZooKeeper之旅

dubbo官网：

需要需要一个监控中心——incubator-dubbo-ops-master

ops属于ali开发的软件，主要功能包括dubbo的admin和monitor两项功能，即注册和监控控制台。

百度搜索dubbo然后点击github，发现阿里的ops已经找不到了，只剩下“dubbo-admin-develop”。

以前可以下载到ops现在下载不到了，无奈安装现有的dubbo-admin-develop莫名出错，而且运行时间又长，只能先找之前的ops包来使用。

不过最后还是让我找到了ops的下载网址(哈哈)：

安装zookeeper

首先解压zookeeper到单独文件夹

进入以下目录新建一个data文件夹

进入配置文件所在区

复制zoo_sample.cfg并命名为zoo.cfg

再去修改zoo.cfg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=../data #修改成上级目录中的data文件夹
# 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

## Metrics Providers
#
# https://prometheus.io Metrics Exporter
#metricsProvider.className=org.apache.zookeeper.metrics.prometheus.PrometheusMetricsProvider
#metricsProvider.httpPort=7000
#metricsProvider.exportJvmInfo=true

修改之后保存退出。

接着需要启动服务器，根据当前路径搜索cmd，之后键入命令zkServer.cmd并回车启动服务：

zkServer.cmd
