zookeeper安装配置

一、下载解压

root@ubuntu:~#wget http://mirrors.cnnic.cn/apache/zookeeper/zookeeper-3.5.1-alpha/zookeeper-3.5.1-alpha.tar.gzroot@ubuntu:~#tar xvf zookeeper-3.5.1-alpha.tar.gz 

二、单机模式（Standalone Operation）

1、创建配置文件conf/zoo.cfg

tickTime=2000dataDir=/var/lib/zookeeperclientPort=2181

2、启动

root@ubuntu:~/zookeeper# bin/zkServer.sh --config conf startZooKeeper JMX enabled by defaultUsing config: conf/zoo.cfgStarting zookeeper ... STARTED

3、客户端连接

root@ubuntu:~/zookeeper# bin/zkCli.sh -server 127.0.0.1:2181Connecting to 127.0.0.1:21812016-08-19 15:09:34,641 [myid:] - INFO  [main:Environment@109] - Client environment:zookeeper.version=3.5.1-alpha-1693007, built on 07/28/2015 07:19 GMT2016-08-19 15:09:34,643 [myid:] - INFO  [main:Environment@109] - Client environment:host.name=ubuntu2016-08-19 15:09:34,643 [myid:] - INFO  [main:Environment@109] - Client environment:java.version=1.8.0_912016-08-19 15:09:34,646 [myid:] - INFO  [main:Environment@109] - Client environment:java.vendor=Oracle Corporation2016-08-19 15:09:34,646 [myid:] - INFO  [main:Environment@109] - Client environment:java.home=/root/jdk/jre2016-08-19 15:09:34,647 [myid:] - INFO  [main:Environment@109] - Client environment:java.class.path=/root/zookeeper/bin/../build/classes:/root/zookeeper/bin/../build/lib/*.jar:/root/zookeeper/bin/../lib/slf4j-log4j12-1.7.5.jar:/root/zookeeper/bin/../lib/slf4j-api-1.7.5.jar:/root/zookeeper/bin/../lib/servlet-api-2.5-20081211.jar:/root/zookeeper/bin/../lib/netty-3.7.0.Final.jar:/root/zookeeper/bin/../lib/log4j-1.2.16.jar:/root/zookeeper/bin/../lib/jline-2.11.jar:/root/zookeeper/bin/../lib/jetty-util-6.1.26.jar:/root/zookeeper/bin/../lib/jetty-6.1.26.jar:/root/zookeeper/bin/../lib/javacc.jar:/root/zookeeper/bin/../lib/jackson-mapper-asl-1.9.11.jar:/root/zookeeper/bin/../lib/jackson-core-asl-1.9.11.jar:/root/zookeeper/bin/../lib/commons-cli-1.2.jar:/root/zookeeper/bin/../zookeeper-3.5.1-alpha.jar:/root/zookeeper/bin/../src/java/lib/*.jar:/root/zookeeper/bin/../conf:2016-08-19 15:09:34,647 [myid:] - INFO  [main:Environment@109] - Client environment:java.library.path=/usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib2016-08-19 15:09:34,648 [myid:] - INFO  [main:Environment@109] - Client environment:java.io.tmpdir=/tmp2016-08-19 15:09:34,648 [myid:] - INFO  [main:Environment@109] - Client environment:java.compiler=<NA>2016-08-19 15:09:34,648 [myid:] - INFO  [main:Environment@109] - Client environment:os.name=Linux2016-08-19 15:09:34,648 [myid:] - INFO  [main:Environment@109] - Client environment:os.arch=amd642016-08-19 15:09:34,648 [myid:] - INFO  [main:Environment@109] - Client environment:os.version=4.4.0-21-generic2016-08-19 15:09:34,648 [myid:] - INFO  [main:Environment@109] - Client environment:user.name=root2016-08-19 15:09:34,648 [myid:] - INFO  [main:Environment@109] - Client environment:user.home=/root2016-08-19 15:09:34,649 [myid:] - INFO  [main:Environment@109] - Client environment:user.dir=/root/zookeeper2016-08-19 15:09:34,649 [myid:] - INFO  [main:Environment@109] - Client environment:os.memory.free=55MB2016-08-19 15:09:34,651 [myid:] - INFO  [main:Environment@109] - Client environment:os.memory.max=228MB2016-08-19 15:09:34,651 [myid:] - INFO  [main:Environment@109] - Client environment:os.memory.total=59MB2016-08-19 15:09:34,654 [myid:] - INFO  [main:ZooKeeper@716] - Initiating client connection, connectString=127.0.0.1:2181 sessionTimeout=30000 watcher=org.apache.zookeeper.ZooKeeperMain$MyWatcher@694f9431Welcome to ZooKeeper!2016-08-19 15:09:34,674 [myid:] - INFO  [main-SendThread(127.0.0.1:2181):ClientCnxn$SendThread@1138] - Opening socket connection to server 127.0.0.1/127.0.0.1:2181.

4、命令行操作

help（查看所有帮助）

ls（查看目录）

[zk: 127.0.0.1:2181(CONNECTED) 2] ls /[zk_test, zk_test_my_data, zookeeper]

三、复制模式（Running Replicated ZooKeeper）

1、配置文件conf/zoo.cfg

tickTime=2000dataDir=/var/lib/zookeeperclientPort=2181initLimit=5syncLimit=2server.1=zoo1:2888:3888server.2=zoo2:2888:3888server.3=zoo3:2888:3888
