《LINUX实操：CentOS 6.5新增加硬盘挂载并实现开机自动挂载》要点：
本文介绍了LINUX实操：CentOS 6.5新增加硬盘挂载并实现开机自动挂载，希望对您有用。如果有疑问，可以联系我们。
在内网主机CentOS 6.5新增一个2T硬盘,先关机断电再衔接硬盘数据线和电源线.
查看当前磁盘装备信息:
[root@linuxidc ~]# fdisk -l

新建目次并挂载
[root@linuxidc ~]# mkdir /wdc
[root@linuxidc ~]# mount /dev/sda /wdc
[root@linuxidc ~]# df -h

设置开机时自动挂载:
查看磁盘UUID信息
[root@linuxidc /]# blkid
/dev/sdb1: UUID="2824-9F12" TYPE="vfat"
/dev/sdb2: UUID="95a58d28-583f-4bd2-a1b8-5217603ab169" TYPE="ext4"

/dev/sda: UUID="d03dad1a-797d-47a5-92c8-5ec5836d35e2" TYPE="ext4"
[root@linuxidc /]# vim /etc/fstab
添加以下信息
UUID=d03dad1a-797d-47a5-92c8-5ec5836d35e2? /wdc? ext4? ? defaults 0 0
编纂后的信息如下:
