单节点伪分布集群（weekend110）的Hive子项目启动顺序

　　因为，我的mysql是用root用户，在/home/hadoop/app/目录下，创建的。

第一步：开启mysql服务

第二步：启动hive

[hadoop@weekend110 app]$ su root
Password:
[root@weekend110 app]# service mysqld start
Starting mysqld: [ OK ]
[root@weekend110 app]# su hadoop
[hadoop@weekend110 app]$ cd hive-0.12.0/
[hadoop@weekend110 hive-0.12.0]$ bin/hive

　　 当然，若是有经验的你，也可以设置成开机自启。这里，关于CentOS还是ubuntu，自行去查阅！
