#以上密碼在正式上生產前要修改

 

 

 

測試及線上配置：

dubbo.registry.address=zookeeper://192.168.1.30:2181?backup=192.168.1.31:2181,192.168.1.32:2181

#操作命令

1. 顯示根目錄下、文件： ls / 使用 ls 命令來查看當前 ZooKeeper 中所包含的內容

[zk: localhost:2181(CONNECTED) 0] ls /

[zookeeper]

2. 顯示根目錄下、文件： ls2 / 查看當前節點數據並能看到更新次數等數據

[zk: localhost:2181(CONNECTED) 0] ls2 /

[zookeeper]

cZxid = 0x0

ctime = Thu Jan 01 08:00:00 CST 1970

mZxid = 0x0

mtime = Thu Jan 01 08:00:00 CST 1970

pZxid = 0x0

cversion = -1

dataVersion = 0

aclVersion = 0

ephemeralOwner = 0x0

dataLength = 0

numChildren = 1

3. 創建文件並設置初始內容：create /zk "test" 創建一個新的znode節點“zk”以及與它關聯的字符串

[zk: localhost:2181(CONNECTED) 0] create /zk "test"

Created /zk

4. 獲取文件內容： get /zk 確認 znode 是否包含我們所創建的字符串

[zk: localhost:2181(CONNECTED) 2] get /zk

"test"

cZxid = 0x300000006

ctime = Tue Nov 15 17:48:54 CST 2016

mZxid = 0x300000006

mtime = Tue Nov 15 17:48:54 CST 2016

pZxid = 0x300000006

cversion = 0

dataVersion = 0

aclVersion = 0

ephemeralOwner = 0x0

dataLength = 6

numChildren = 0

5. 修改文件內容： set /zk "zkbak" 對zk所關聯的字符串進行設置

[zk: localhost:2181(CONNECTED) 0] set /zk "zkbak"

cZxid = 0x300000006

ctime = Tue Nov 15 17:48:54 CST 2016

mZxid = 0x300000008

mtime = Tue Nov 15 17:50:30 CST 2016

pZxid = 0x300000006

cversion = 0

dataVersion = 1

aclVersion = 0

ephemeralOwner = 0x0

dataLength = 7

numChildren = 0

6. 刪除文件： delete /zk 將剛纔創建的znode刪除

7. 刪除目錄（即使非空）：rmr 目錄 如可用於刪除Kafka的某個Consumer Group

8. 退出客戶端： quit

9. 幫助命令： help

[zk: localhost:2181(CONNECTED) 1] help

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
