Zookeeper(五)：單機版測試、叢集測試、建立根節點
阿新 • • 發佈：2019-02-13
我們已經搭建好了zookeeper的單機版、偽叢集版、叢集版，現在啟動客戶端連上zkServer進行測試
一、單機版測試
1.1、命令測試
連線上zookeeper的server：zkCli.sh -server 192.168.133.149:2180
# 連線zookeeper單機版的server
[[email protected] bin]# ./zkCli.sh -server 192.168.133.149:2180
# 連線上的日誌
[[email protected] bin]# ./zkCli.sh -server localhost:2180
Connecting to localhost:2180
2018-02-06 13:54:53,970 [myid:] - INFO [main:
由上面日誌可以看出還沒有建立節點目錄，下面我們使用create /service /CEMS_SERVICE新增一個根節點目錄/CEMS_SERVICE
使用 get /service檢視是否新增成功
# 新增一個根節點目錄/CEMS_SERVICE
[zk: localhost:2180(CONNECTED) 0] create /service CEMS_SERVICE
Created /service
# 檢視新增的節點
[zk: localhost:2180(CONNECTED) 1] get /service
CEMS_SERVICE
cZxid = 0x2
ctime = Tue Feb 06 14:07:41 CST 2018
mZxid = 0x2
mtime = Tue Feb 06 14:07:41 CST 2018
pZxid = 0x2
cversion = 0
dataVersion = 0
aclVersion = 0
ephemeralOwner = 0x0
dataLength = 12
numChildren = 0
[zk: localhost:2180(CONNECTED) 2]說明單機配置成功
