四 ZooKeeper常用命令行操作 通过./zkCli.sh 打开zk的客户端进入命令行后台 ls/ls2 列出当前节点下的子节点 ls2还会列出当前节点的状态 [zk: localhost:2181(CONNECTED) 5] ls2 / [cluster, controller_epoch, brokers, zookeeper, admin, isr_change_notification, consumers,
一、节点增删改查 1.1 启动服务和连接服务 # 启动服务 bin/zkServer.sh start #连接服务 不指定服务地址则默认连接到localhost:2181 zkCli.sh -server hadoop001:2181 1.2 help命令 使用help可以查看所有命令及格式。 1.3 查看节点列表 查看节点列表有ls path和 ls2 pat
一、前言 为了避免存储在Zookeeper上的数据被其他程序或者人为误修改，Zookeeper提供了ACL(Access Control Lists)进行权限控制。只有拥有对应权限的用户才可以对节点进行增删改查等操作。下文分别介绍使用原生的Shell命令和Apache Curator客户端进行权限设置。 二、使用Shel
zookeeper CLI 1，查看所有命令 启动zookeeper并使用bin目录下的zkCli.sh连接zookeeper服务器，输入任何zookeeper不能识别的命令，zookeeper都会列出所有可供使用的命令： [zk: 127.0.0.1:2184(CONNECTED) 105] k ZooKeeper -server host:port cmd args stat path [watch]
Consider a graph G formed from a large number of nodes connected by edges. G is said to be connected if a path can be found in 0 or more steps between any pair of nodes in G. For example, the graph below is not connected because there is no path from A to

不同协议之间的路由，是不会相互交换的。 一、路由重发布的意义： 1、把一种协议的路由注入到另一种协议当中，譬如把RIP的路由注入到OSPF当中 2、把同一种路由协议的一个进程注入到另一个进程中，譬如把OSPF的进程31注入到32当中 二、重发布需要考虑的问题： 1、只有在路由表中的路由才可以
