Linux (CentOS) Mount U disk, mobile hard disk and file copy, backup __linux

Description
Environment: VMware Workstation
System: centos6.2
The following actions are performed under root

1.U Disk Mount

MKDIR/MNT/USB//Create a directory for mounting USB drive
Fdisk-l//View the System Mount U disk, if the system has a hard disk SDB1 on behalf of your U disk,/DEV/SDB1 show that the machine has identified the U disk,
MOUNT/DEV/SDB1/MNT/USB///DEV/SDB1 mount the U disk to the/MNT/USB directory
CD/MNT/USB//Enter U disk directory, you can view the contents of U disk
Umount/mnt/usb or UMOUNT/DEV/SDB1//uninstall U disk

2. mount a removable hard drive
We usually use the mobile hard disk is in NTFS format, Linux by default is not supported NTFS partitions, so need to install a Third-party plug-in ntfs-3g Linux.

Install ntfs-3g
Yum install gcc//install compiler, always press Y, and if you fail to compile ntfs-3g after installing GCC, GCC is a compiler for programming in Linux.

MKDIR/USR/LOCAL/NTFS3G//Create folder ntfs3g for later compile installation ntfs-3g
CD/USR/LOCAL/SRC//linux The default source code package storage location; Source Package compile installation bit
Place:/usr/local/software name
wget http://tuxera.com/opensource/ntfs-3g_ntfsprogs-2011.4.12.tgz//Download ntfs-3g
Tar zxvf ntfs-3g_ntfsprogs-2011.4.12.tgz/decompression ntfs-3g software compression pack
CD ntfs-3g_ntfsprogs-2011.4.12//Enter just unzipped folder, do not know directory name can be used LS to view directory name
./configure--prefix=/usr/local/ntf3g//compilation, specifying the installation directory/usr/local/ntf3g
Make&&make Install//compile installation
CD//Back to root directory
Rm-r-F ntfs-3g_ntfsprogs*//Delete all ntfs-3g_ntfsprogs headed all files without a reminder, "*" means match all, r recursive processing, will All files and subdirectories under the specified directory are processed together, and-F forces the file or directory to be deleted.

Mount
Fdisk-l//View mount information to see if the system recognizes the removable hard drive,/dev/sda1 represents the first partition of the first hard drive,/DEV/SDB1 represents the first partition of the second hard drive,

disk/dev/sdb:160.0 GB, 160041885696 bytes
255 heads, Sectors/track, 19457 cylinders
Units = Cylinders of 16065 * 8225280 bytes
Sector size (logical/physical): bytes/512 bytes
I/O size (minimum/optimal): bytes/512 bytes
Disk identifier:0x7ab8d700

Device Boot Start End Blocks Id System
/DEV/SDB1 * 1 5222 41945683+ 7 hpfs/ntfs
/DEV/SDB2 5223 10444 41945715 7 hpfs/ntfs
/DEV/SDB3 10445 15666 41945715 7 hpfs/ntfs
/DEV/SDB4 15667 19457 30451207+ 7 hpfs/ntfs
The above is my drive a piece of information

CD/MNT//Enter directory
mkdir usb1 USB2 USB3 usb4//Create 4 directories mount a removable hard disk separately mount command one:

Ntfs-3g/dev/sdb1/mnt/usb1-o Locale=ar_sa. UTF-8, the red part can also be changed to ZH_CN. GBK, it is obvious that the use of some kind of code to mount, to prevent garbled;//mount each partition to the corresponding directory, the following section can not add

Ntfs-3g/dev/sdb2/mnt/usb2-o Locale=ar_sa. UTF-8
Ntfs-3g/dev/sdb3/mnt/usb3-o Locale=ar_sa. UTF-8
Ntfs-3g/dev/sdb4/mnt/usb4-o Locale=ar_sa. UTF-8
Mount Command two:
Mount NTFS-3G/DEV/SDB1/MNT/USB1
......
LS//view mobile hard drive information
Copy, back up files
Cp-r/web/mnt/usb1//Copy all files in the Web directory into the/MNT/USB1 directory, that is, copy to the/DEV/SDB1 partition on the mounted mobile hard disk
UMOUNT/DEV/SDB1 or UMOUNT/MNT/USB1//uninstall mounted removable drive

Mount the removable hard drive automatically on the boot
----Edit/etc/fstab
Cp/etc/fstab/etc/fstabbak//edit before the backup, develop this good habit.
Vi/etc/fstab//Edit the file, add the following information at the end of the file, and press G (SHIFT+G) at the end of the jump file
/DEV/SDB1/MNT/USB1 ntfs-3g Defaults 0 0
/DEV/SDB2/MNT/USB2 ntfs-3g Defaults 0 0
/DEV/SDB3/MNT/USB3 ntfs-3g Defaults 0 0
/DEV/SDB4/MNT/USB4 ntfs-3g Defaults 0 0
: wq! Save exit and the system will automatically mount the removable hard drive after reboot
