Mount command

Mount [–l] #查看系统中已经挂载的设备

Mount–a #依据配置文件/etc/fstab content, automatically mount, to detect the correct contents of the file

Mount [-t file system] [-l volume label name] [-o Special Options] device file name mount point

you can use \ To break a line when the command line is not written

-T File system: Specifies the type of mount, which can be ext3, EXT4, ISO 9660, and other file system-L volume label name: Mount the partition of the specified volume label instead of installing the device file name mount

-O Special option: You can specify additional options for mounting, such as read and write permissions, synchronous async, etc., not specified as default values

Atime/noatime Update access time, do not update access time. When accessing a partition file, whether to update the access time of the file, the default is update

Async/sync asynchronous/synchronous, default to asynchronous

Auto/noauto Automatic/Manual, when the Mount–a command executes, the/etc/fstab file content mount is automatically installed, the default is auto

Defaults defines the default value, which is equivalent to the seven options of Rw,suid,dev,exec,auto,nouser,async

Exec/noexec Execute/Not execute, set whether executable file is allowed in file system, default is allow

Remount re-mounts the mounted file system, which is typically used to specify special permissions to modify

Re/ro read/write/read-only, file system mount, read and write permissions, default is RW

Suid/nosuid has/does not have SUID permissions, set whether the file system has suid and Sgid permissions, the default is to have

User/nouser Allow/Disallow normal user mount, set whether the file system allows ordinary users to mount, default is not allowed, only root can mount the partition

Usrquota write on behalf of file system support user disk quotas, default does not support

Grpquota write represents the file system support Group disk quotas, which are not supported by default

Mount–o remount,noexec/boot #重新挂载/boot partition and use noexec permissions

Mkdir/mnt/cdrom

Mount–t Iso9660/dev/cdrom/mnt/cdrom #光盘挂载

Umount/mnt/cdrom #光盘卸载

Fdisk–l #查看所有分区, determine the device file name of the U disk

Mkdir/mnt/usb #建立挂载点

Mount–t vfat–o iocharset=utf8/dev/sdb1/mnt/usb #挂载U盘, specify Chinese encoding to UTF8

utf8=gb2312

Common drivers in Linux are placed in the kernel, and infrequently used drivers become modules. Both the module and the library are functions.

*.ko Drive *.so function

Linux default does not recognize NTFS format, if you want to use it, you must recompile the kernel

Mount NTFS partitions

1. Recompile

2. Loading the NTFS module

Uname–r #查看本机内核版本

Download kernel version similar to core

TAR–JXVF linux-2.6.32.tar.bz2 #解压内核压缩包

Cp–r linux-2.6.32/usr/src/kernels/#复制内核源码到默认内核源码保存位置

Mount/dev/cdrom/mnt/cdrom

rpm–ivh/mnt/cdrom/packages/kernel-devel-2.6.32-279.el6.i686.rpm

#安装rpm包的不完整内核源码

cp/usr/src/kernels/2.6.32-279.el6.i686/.config/usr/src/kernels/linux-2.6.32/

#从rpm包的内核源码中, copy the. config file into the source bundle's kernel source code

Vi/usr/src/kernels/linux-2.6.32/.config

Config_ntfs_fs=m

cd/usr/src/kernels/linux-2.6.32/

#编译命令一定要进入内核目录才能执行, because the compilation command compiles the current directory

Make modules #安装模块, during the execution of the command, you will need to select which modules need to be installed, select only the NTFS related modules, the other modules do not install

NTFS File system Support (NTFS_FS) [m/n/y/?] M

NTFS Debugging support (Ntfs_debug) [n/y/?] (NEW) Y

NTFS Write Support (NTFS_RW) [n/y/?] (NEW) Y

#编译过程结束就能看到ntfs. KO modules

Ll/usr/src/kernels/linux-2.6.32/fs/ntfs/ntfs.ko

CP fs/ntfs/ntfs.ko/lib/modules/2.6.32-279.el6.i686/kernel/fs/

#把ntfs. Ko copy to the specified location

Depmod–a #扫描所有模块

Modprobe–f NTFS #强制安装ntfs模块

Lsmod | grep NTFS #查询安装的ntfs模块

3. Installing the NTFS file system module using NTFS-3G

www.tuxera.com/community/ntfs-3g-download/download ntfs-3g plugin to Linux server

Before compiling and installing the NTFS-3G plug-in, ensure that the GCC compiler is installed

TAR–ZXVF ntfs-3g_ntfsprogs-2013.1.13.tgz #解压

CD ntfs-3g_ntfsprogs-2013.1.13 #进入解压目录

./configure #编译器准备

Make install #编译安装

Mount–t Ntfs-3g/dev/sdb1/mnt/win #挂载

VI Editor: Full-screen plain text editor, Vim is a reinforced version of VI. (Vimtutor Open Manual)

VI working mode: Command mode, input mode, last line mode

A specifier insert in the word cursor

A at the end of the line where the cursor is inserted

I match either insert in the word cursor

I Insert at the beginning of the line where the cursor

o Insert a new line under the cursor

O insert a new line on the cursor
