TIP
本文主要是介绍 Zookeeper-开发配置 。
# Zookeeper 4、Zookeeper开发
# 1、登录Zookeeper客户端
#通过zkCli.sh可以登录到Zookeeper
$ cd /usr/local/zookeeper-3.4.6/bin
$ ./zkCli.sh
#如果显示下面这样就说明登录成功了
JLine support is enabled
WATCHER::
WatchedEvent state:SyncConnected type:None path:null
[zk: localhost:2181(CONNECTED) 0]
# 2、如何在Zookeeper下使用帮助文档
#通过 -h命令可以可看Zookeeper下的所有命令和使用方法
[zk: localhost:2181(CONNECTED) 0] -h
ZooKeeper -server host:port cmd args
connect host:port
get path [watch]
ls path [watch]
set path data [version]
rmr path
delquota [-n|-b] path
quit
printwatches on|off
create [-s] [-e] path data acl
stat path [watch]
close
ls2 path [watch]
history
listquota path
setAcl path acl
getAcl path
sync path
redo cmdno
addauth scheme auth
delete path [version]
setquota -n|-b val path
下面是一些小练习:
#查看所有目录
ls /
#在Zookeeper的根目录下创建一个test的文件 内容是xxx
create / test2 womendoushixiaoxueshen
# 获取一个文件的值,下面是输出信息
get /test2
#womendoushixiaoxueshen
#cZxid = 0x4300000003
#ctime = Sun Mar 13 13:28:53 CST 2016
#mZxid = 0x4300000004
#mtime = Sun Mar 13 14:12:15 CST 2016
#pZxid = 0x4300000003
#cversion = 0
#dataVersion = 1
#aclVersion = 0
#ephemeralOwner = 0x0
#dataLength = 10
#numChildren = 0
#重新设置一个文件的值
set /test2 helloword
#删除一个文件或目录
rmr /test2
