zookeeper的簡單部署與使用

1、以zookeeper-3.4.7版本爲例，從官網下對應的gz包，丟到環境主機上，解壓，建議目錄重命名規則爲zookeeper-3.4.7-x，其中x爲zk節點序列。

2、以部署三個zk節點爲例，調整配置如下：

zookeeper-3.4.7-1/conf/zoo.cfg

tickTime=2000
initLimit=4
syncLimit=2
dataDir=/home/user/zookeeper-3.4.7-1/usr/data
dataLogDir=/home/user/zookeeper-3.4.7-1/usr/logs
clientPort=4181
server.1=localhost:4190:4191
server.2=localhost:4192:4193

server.3=localhost:4194:4195

zookeeper-3.4.7-2/conf/zoo.cfg

tickTime=2000
initLimit=4
syncLimit=2
dataDir=/home/user/zookeeper-3.4.7-2/usr/data
dataLogDir=/home/user/zookeeper-3.4.7-2/usr/logs
clientPort=4182
server.1=localhost:4190:4191
server.2=localhost:4192:4193

server.3=localhost:4194:4195

zookeeper-3.4.7-3/conf/zoo.cfg

tickTime=2000
initLimit=4
syncLimit=2
dataDir=/home/user/zookeeper-3.4.7-3/usr/data
dataLogDir=/home/user/zookeeper-3.4.7-3/usr/logs
clientPort=4183
server.1=localhost:4190:4191
server.2=localhost:4192:4193

server.3=localhost:4194:4195

3、創建dataDir/dataLogDir目錄。

4、啓動zk節點

zkServer.sh start

5、驗證

zkCli.sh -server localhost:4183

[zk: localhost:4183(CONNECTED) 1] ls /

[zookeeper]

[zk: localhost:2181(CONNECTED) 2] create /test "test"

Created /test

[zk: localhost:2181(CONNECTED) 3] ls /

[zookeeper, test]

[zk: localhost:2181(CONNECTED) 4] get /test
"test"
