在启动hbase时，要提前确保HDFS和zookeeper是已经启动状态，
先用jps，查询全部启动的进程

[root@node01 ~]# jps
2816 DataNode
6642 RunJar
3074 ResourceManager
2677 NameNode
6454 RunJar
5992 HRegionServer
5833 HMaster
2169 -- process information unavailable
7562 Jps
3597 QuorumPeerMain
3182 NodeManager

HDFS的进程名：：：2816 DataNode 2677 NameNode
zookeeper的进程名：：：3597 QuorumPeerMain

启动HDFS和zookeeper前，
一定要关闭防火墙 和所有节点的时间同步
一定要关闭防火墙 和所有节点的时间同步
一定要关闭防火墙 和所有节点的时间同步
一定要关闭防火墙 和所有节点的时间同步
一定要关闭防火墙 和所有节点的时间同步
一定要关闭防火墙 和所有节点的时间同步

关闭防火墙命令：

[root@node01 ~]# service iptables stop
iptables: Setting chains to policy ACCEPT: filter          [  OK  ]
iptables: Flushing firewall rules:                         [  OK  ]
iptables: Unloading modules:                               [  OK  ]
[root@node01 ~]# chkconfig iptables off

查询防火墙命令：

[root@node01 ~]# service iptables status
iptables: Firewall is not running

永久关闭防火墙命令：

[root@node01 ~]# chkconfig iptables off

所有节点的时间同步命令：ntpdate ntp2.aliyun.com
建议再总命令行执行次命令

确保防火墙关闭和时间同步无误后，在启动hdfs和zookeeper的进程

如果没有HDFS的进程名，则需要启动HDFS，
启动方法：start-all.sh
启动完后，在用jps查看下是否启动成功

[root@node01 ~]# start-all.sh
This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh

HDFS启动成功，先登录hdfs的web页面查看下，
hdfs的web页面端口号：50070

启动zookeeper进程：
1、先要到zookeeper目录中的bin目录下
2、在bin目录中执行 zkServer.sh start
执行完，在用jps查看zookeeper的进程名：QuorumPeerMain

[root@node01 ~]# cd /export/servers/zookeeper/bin
[root@node01 bin]# zkServer.sh start
[root@node01 bin]# jps
8689 NodeManager
9476 Jps

8582 ResourceManager
5992 HRegionServer
8184 NameNode
9448 QuorumPeerMain
5833 HMaster

确保hdfs跟zookeeper启动成功后，
再启动HBase
一键启动：start-hbase.sh

HBase的web端口号为：60010 可以登陆下，看看hbase是否启动成功
