查看jdk环境的版本

执行java –version和javac –version命令

[root@node10 ~]# java -version  java version "1.6.0_37"  Java(TM) SE Runtime Environment (build 1.6.0_37-b06)  Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01, mixed mode)

下载并解压zookeeper 

cd /opt  tar xzvf zookeeper-3.3.5.tar.gz

重命名zookeeper的配置文件

mv /opt/zookeeper-3.3.5/conf/zoo_sample.cfg  zoo.cfg

编辑修改zoo.cfg

dataDir=/opt/zookeeper-3.3.5/data

创建数据目录：mkdir /opt/zookeeper-3.3.5/data

mkdir  /opt/zookeeper-3.3.5/data

启动zookeeper

1. /opt/zookeeper-3.3.5/bin/zkServer.sh start 

2. JMX enabled by default
   Using config: /opt/zookeeper-3.3.5/bin/../conf/zoo.cfg
   Starting zookeeper ... STARTED 

检查zookeeper进程

ps -ef | grep zookeeper | grep -v grep  oot     29530     1  0 15:39 pts/0    00:00:00 /usr/java/jdk1.6.0_37/bin/java -Dzookeeper.log.dir=. -Dzookeeper.root.logger=INFO,CONSOLE -cp /opt/zookeeper-3.3.5/bin/../build/classes:/opt/zookeeper-3.3.5/bin/../build/lib/*.jar:/opt/zookeeper-3.3.5/bin/../zookeeper-3.3.5.jar:/opt/zookeeper-3.3.5/bin/../lib/log4j-1.2.15.jar:/opt/zookeeper-3.3.5/bin/../lib/jline-0.9.94.jar:/opt/zookeeper-3.3.5/bin/../src/java/lib/*.jar:/opt/zookeeper-3.3.5/bin/../conf:.:/usr/java/jdk1.6.0_37/lib/dt.jar:/usr/java/jdk1.6.0_37/lib/tools.jar -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false org.apache.zookeeper.server.quorum.QuorumPeerMain /opt/zookeeper-3.3.5/bin/../conf/zoo.cfg

还可以用以下方法检测是否启动成功

/opt/zookeeper-3.4.3/bin/zkCli.sh 或 echo stat|nc localhost 2181

 停止zookeeper

kill -9  29530
