Hadoop之zookeeper快速安装
查看jdk环境的版本执行java –version和javac –version命令
# java -versionjava 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 /opttar 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.cfgzoo.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
[*] /opt/zookeeper-3.3.5/bin/zkServer.sh start
[*] 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 grepoot 29530 10 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
