Zookeeper的多节点集群详细启动步骤（3或5节点）

分为

　　（1）分别去3或5节点上去启动Zookeeper进程

　　（2）自己写个脚本，直接在主节点上去启动Zookeeper进程。

（1）分别去3或5节点上去启动Zookeeper进程

　　第一步：

[hadoop@HadoopMaster zookeeper-3.4.6]$ pwd
/home/hadoop/app/zookeeper-3.4.6
[hadoop@HadoopMaster zookeeper-3.4.6]$ jps
3113 Jps
[hadoop@HadoopMaster zookeeper-3.4.6]$ bin/zkServer.sh start
JMX enabled by default
Using config: /home/hadoop/app/zookeeper-3.4.6/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[hadoop@HadoopMaster zookeeper-3.4.6]$ jps
3133 QuorumPeerMain
3146 Jps
[hadoop@HadoopMaster zookeeper-3.4.6]$

　　第二步：

[hadoop@HadoopSlave1 hadoop-2.6.0]$ cd $ZOOKEEPER_HOME
[hadoop@HadoopSlave1 zookeeper-3.4.6]$ pwd
/home/hadoop/app/zookeeper-3.4.6
[hadoop@HadoopSlave1 zookeeper-3.4.6]$ jps
3088 Jps
[hadoop@HadoopSlave1 zookeeper-3.4.6]$ bin/zkServer.sh start
JMX enabled by default
Using config: /home/hadoop/app/zookeeper-3.4.6/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[hadoop@HadoopSlave1 zookeeper-3.4.6]$ jps
3122 Jps
3109 QuorumPeerMain
[hadoop@HadoopSlave1 zookeeper-3.4.6]$

　　第三步：
[hadoop@HadoopSlave2 ~]$ cd $ZOOKEEPER_HOME
[hadoop@HadoopSlave2 zookeeper-3.4.6]$ pwd
/home/hadoop/app/zookeeper-3.4.6
[hadoop@HadoopSlave2 zookeeper-3.4.6]$ jps
4511 Jps
[hadoop@HadoopSlave2 zookeeper-3.4.6]$ bin/zkServer.sh start
JMX enabled by default
Using config: /home/hadoop/app/zookeeper-3.4.6/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[hadoop@HadoopSlave2 zookeeper-3.4.6]$ jps
4531 QuorumPeerMain
4545 Jps
[hadoop@HadoopSlave2 zookeeper-3.4.6]$

　　这里，我以3节点作为演示，5个节点的Zookeeper大同小异，不多赘述。

（2）自己写个脚本，直接在主节点上去启动Zookeeper进程。

[hadoop@djt11 zookeeper]$ runRemoteCmd.sh "/home/hadoop/app/zookeeper/bin/zkServer.sh start" zookeeper
