挂在硬盘和挂在iso镜像

 

给硬盘分区

[root@localhost ~]# fdisk /dev/sdb     //接上硬盘之后，使用fdisk命令分区

 

The number of cylinders for this disk is set to 1044.

There is nothing wrong with that, but this is larger than 1024,

and could in certain setups cause problems with:

1) software that runs at boot time (e.g., old versions of LILO)

2) booting and partitioning software from other OSs

   (e.g., DOS FDISK, OS/2 FDISK)

 

Command (m for help): m      //使用m查看选项

Command action

   a   toggle a bootable flag

   b   edit bsd disklabel

   c   toggle the dos compatibility flag

   d   delete a partition

   l   list known partition types

   m   print this menu

   n   add a new partition     //添加一个分区

   o   create a new empty DOS partition table

   p   print the partition table    //查看现有分区

   q   quit without saving changes   //推出但不保存

  s    create a new empty Sun disklabel

   t   change a partition's system id

   u   change display/entry units

   v   verify the partition table

   w   write table to disk and exit    //保存并推出

   x   extra functionality (experts only)

Command (m for help): p       //查看现有分区

挂在硬盘

[root@localhost /]# mount /dev/sdb5 /text

[root@localhost /]# ls /text

lost+found

在/etc/fstab里面添加开机启动

[root@localhost /]# vim /etc/fstab

/dev/VolGroup00/LogVol00 /                        ext3    defaults        1 1

LABEL=/boot              /boot                   ext3    defaults        1 2

devpts                   /dev/pts                devpts gid=5,mode=620 0 0

tmpfs                    /dev/shm                tmpfs   defaults        0 0

proc                     /proc                   proc    defaults        0 0

sysfs                    /sys                    sysfs   defaults        0 0

/dev/VolGroup00/LogVol01 swap                     swap    defaults        0 0

# Beginning of the block added by the VMware software

.host:/                  /mnt/hgfs               vmhgfs defaults,ttl=5     0 0

# End of the block added by the VMware software

/dev/sdb1                /test                   ext2    defaults        0 0

/dev/sdb5                /text                   ext3    defaults        0 0

第一字段 设置是硬盘文件

第二字段 挂在的目录

第三字段 使用的文件格式

第四字段 硬盘使用的参数

defaults 同时具有 rw, suid, dev, exec, auto, nouser, async 等参数。 基本上，预讴情�晔褂� defaults 讴定即可！

第五字段 能否被dump命令备份

0 代表丌要做 dump 备�В� 1 代表要每天运行dump 的动作。 2 也代表其他额定日期的 dump 备份动作， 通常这个数值是 0 就是 1 啦！

是否检验扇区

在这个字段中，我们可以讴定是否要以 fsck 检验该 filesystem 喔。 0 是不要要检验， 1 表示最早检验(一般�秤懈�目��会讴定为 1)， 2 也是要检验，不过 1 会比较早被检验啦！ 一般来说，根目录定为 1 ，其他的要检验的 filesystem 都设定为 2 就好了。

挂在iso镜像

[root@localhost ~]# mount -o loop /mnt/hgfs/xunin/rhel.5.0.server.centoschina.com.dvd.iso /mnt/iso/

[root@localhost ~]# ls /mnt/iso/
