[Email protected] softs]# wget http://mirrors.cnnic.cn/apache/zookeeper/zookeeper-3.4.8/zookeeper-3.4.8.tar.gz

[Email protected] softs]# tar XF zookeeper-3.4.8.tar.gz-c/app/

[Email protected] softs]# ln-s/app/zookeeper-3.4.8//app/zookeeper

[[Email protected] softs]# CD

Configure startup

[Email protected] ~]# cd/app/zookeeper/conf/

[email protected] conf]# CP zoo_sample.cfg ZOO.CFG

[[email protected] conf]# grep ^[a-z] Zoo.cfg

ticktime=2000

Datadir=/data/zookeeper

[Email protected] ~]# Source/etc/profile

[[email protected] ~]# zkserver.sh start

ZooKeeper JMX enabled Bydefault

Using config:/app/zookeeper/bin/. /conf/zoo.cfg

Starting zookeeper ... STARTED

Connection Zookeeper

Java Connection

[Email protected] ~]# Zkcli.sh-server 127.0.0.1:2181

Connecting to localhost:2181

C Connection

[Email protected] ~]# cd/app/zookeeper/src/c

[Email protected] c]#./configure

In the Zookeeper src/c directory, but the client is relatively low in the new version.

Operation Zookeeper

Once connected to zookeeper, you can execute some commands, just like in a file system

List

[zk:127.0.0.1:2181 (CONNECTED) 0] LS/

[Zookeeper]

Create a new Znode

Perform Create/zk_test my_data. This creates a new Znode, and the string my_data is associated with the node

[Zk:127.0.0.1:2181 (CONNECTED) 1] create/zk_test My_data

Created/zk_test

[Zk:127.0.0.1:2181 (CONNECTED) 2] LS/

[Zookeeper, Zk_test]

Verify

You can verify that the data is associated with this znode by command get/zk_test.

[Zk:127.0.0.1:2181 (CONNECTED) 3] Get/zk_test

My_data

Czxid = 0x14

CTime = Sat June 23:41:57CST 2016
