一、啟動ZooKeeper集群

sh /opt/modules/zookeeper-3.4.14/bin/zkServer.sh start[hadoop@centos01 ~]$ sh /opt/modules/zookeeper-3.4.14/bin/zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /opt/modules/zookeeper-3.4.14/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

查看狀態
sh /opt/modules/zookeeper-3.4.14/bin/zkServer.sh status[hadoop@centos03 dataDir]$ sh /opt/modules/zookeeper-3.4.14/bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/modules/zookeeper-3.4.14/bin/../conf/zoo.cfg
Mode: leader

二、啟動HDFS

sh /opt/modules/hadoop-2.8.2/sbin/start-dfs.sh[hadoop@centos01 ~]$ sh /opt/modules/hadoop-2.8.2/sbin/start-dfs.sh
Starting namenodes on [centos01 centos02]
centos01: starting namenode, logging to /opt/modules/hadoop-2.8.2/logs/hadoop-hadoop-namenode-centos01.out
centos02: starting namenode, logging to /opt/modules/hadoop-2.8.2/logs/hadoop-hadoop-namenode-centos02.out
centos03: starting datanode, logging to /opt/modules/hadoop-2.8.2/logs/hadoop-hadoop-datanode-centos03.out
centos01: starting datanode, logging to /opt/modules/hadoop-2.8.2/logs/hadoop-hadoop-datanode-centos01.out
centos02: starting datanode, logging to /opt/modules/hadoop-2.8.2/logs/hadoop-hadoop-datanode-centos02.out
Starting journal nodes [centos01 centos02 centos03]
centos03: starting journalnode, logging to /opt/modules/hadoop-2.8.2/logs/hadoop-hadoop-journalnode-centos03.out
centos02: starting journalnode, logging to /opt/modules/hadoop-2.8.2/logs/hadoop-hadoop-journalnode-centos02.out
centos01: starting journalnode, logging to /opt/modules/hadoop-2.8.2/logs/hadoop-hadoop-journalnode-centos01.out[hadoop@centos01 dataDir]$ jps
34278 NameNode
34535 DataNode
32328 QuorumPeerMain
35420 JournalNode
35981 Jps

啟動守護進程

sh /opt/modules/hadoop-2.8.2/sbin/hadoop-daemon.sh start zkfc

三、啟動YARN集群

啟動ResourceManager進程。 centos01、centos02

sh /opt/modules/hadoop-2.8.2/sbin/yarn-daemon.sh start resourcemanager[hadoop@centos01 ~]$ sh /opt/modules/hadoop-2.8.2/sbin/yarn-daemon.sh start resourcemanager
starting resourcemanager, logging to /opt/modules/hadoop-2.8.2/logs/yarn-hadoop-resourcemanager-centos01.out

啟動 NodeManager 3個節點

sh /opt/modules/hadoop-2.8.2/sbin/yarn-daemon.sh start nodemanager[hadoop@centos01 ~]$ sh /opt/modules/hadoop-2.8.2/sbin/yarn-daemon.sh start nodemanager
starting nodemanager, logging to /opt/modules/hadoop-2.8.2/logs/yarn-hadoop-nodemanager-centos01.out

四、啟動Hbase

在centos01節點啟動hbase

啟動
sh /opt/modules/hbase-2.1.9/bin/start-hbase.sh
停止
sh /opt/modules/hbase-2.1.9/bin/stop-hbase.sh
