linux mount挂接新硬盘/光盘/U盘/移动硬盘/ISO并加载使用手记
================================================================================
一、过程步骤
1、#kudzu //检测新硬件,这一步必须!
2、#fdisk -l //查看是否找到新的硬盘,查看硬盘代号。
3、#fdisk /dev/sdb //为新硬盘分区,例如分成sdb1
#mkfs.ext3 /dev/sdb1 //把新硬盘格式化成ext3格式
4、#mkdir /disk2 //创建新的挂载点
5、#mount /dev/sdb1 /disk2/ //手动挂载分区,把硬盘挂到/disk2目录下。
6、#vi /etc/fstab
/dev/sdb1 /disk2 ext3 auto 1 2 //设置为开机自动挂载分区。

180 days, whichever comes first. Use tune2fs -c or -i to override.

5、设置为开机自动挂载分区
[root@AMD-LINUX ~]# vi /etc/fstab
/dev/sdb1 /disk2 ext3 auto 1 2
6、手动挂载分区
[root@AMD-LINUX ~]# mount /dev/sdb1 /disk2

补充说明:

1/ windows 共享挂接

mount -t smbfs -o username=administrator,password=pldy123 //10.140.133.23/c$ /mnt/samba

2/ 挂接U盘

mount -t vfat /dev/sdd1 /mnt/usb

3/ 挂接移动硬盘

mount -t ntfs -o iocharset=cp936 /dev/sdc1 /mnt/usbhd1

-o iocharset=cp936 如果不乱码可以不加

4/ 从光盘制作光盘镜像文件

#cp /dev/cdrom /home/sunky/mydisk.iso 或
#dd if=/dev/cdrom of=/home/sunky/mydisk.iso

5/ 将文件和目录制作成光盘镜像文件

mkisofs -r -J -V mydisk -o /home/sunky/mydisk.iso /home/sunky/mydir
注:这条命令将/home/sunky/mydir目录下所有的目录和文件制作成光盘镜像文件/home/sunky/mydisk.iso,光盘卷标为:mydisk

6/ 挂接光盘文件
mount -o loop -t iso9660 /home/sunky/mydisk.iso /mnt/vcdrom
