Mount command details

Command Format:

Mount [-T vfstype] [-O options] device dir

Where:

1.-T vfstype specifies the type of the file system, which is usually not required. Mount automatically selects the correct type. Common types include:

CD or CD image: iso9660

DOS fat16 File System: msdos

Windows 9x FAT32 File System: vfat

Windows nt ntfs file system: NTFS

Mount Windows File network sharing: smbfs

Network Sharing for Unix (Linux) files: NFS

2.-O options is used to describe the mounting method of a device or file. Common parameters include:

Loop: used to connect a file to the system as a hard disk partition.

RO: mounting a device in read-only mode

RW: mounting a device in read/write mode

Iocharset: Specifies the character set used to access the file system

3. the device to be mounted.

4. mount point of the Dir device on the system ).

I. Attach a CD image file

1. Create a CD image file from the CD. Put the CD in the optical drive and execute the following command

# Dd If =/dev/CDROM of =/home/sunky/mydisk. ISO

 

2. Make the files and directories into a CD image file and execute the following command

# Mkisofs-r-J-V mydisk-o/home/sunky/mydisk. ISO/home/sunky/mydir

 

3. Mount the disk image file)
# Mkdir/mnt/vcdrom
Note: create a directory for mount point)

# Mount-o loop-T iso9660/home/sunky/mydisk. ISO/mnt/vcdrom
Note: You can use/mnt/vcdrom to access all files in the disk image file mydisk. ISO.

 

2. Mount the mobile hard drive

For Linux systems, mobile hard disks with USB interfaces are treated as SCSI devices. Before inserting a mobile hard disk, use fdisk-l

Or more/proc/partitions to view the hard disk and hard disk partition of the system.

# Mount-t ntfs/dev/sdc1/mnt/usbhd1

# Mount-T vfat/dev/sdc5/mnt/usbhd2
Note: The-t ntfs parameter should be used for Disk Partitions In NTFS format, and the-T vfat parameter should be used for disk partitions in FAT32 format.

If the Chinese character file name is garbled or not displayed, you can use the following command format.

# Mount-t ntfs-O iocharset = cp936/dev/sdc1/mnt/usbhd1
# Mount-T vfat-O iocharset = cp936/dev/sdc5/mnt/usbhd2

In Linux, you can use the fdisk partition command and The mkfs file system creation command to create a partition of a mobile hard disk as a Linux System

Some ext2 and ext3 formats. In this way, it is more convenient to use in Linux. Use the following command to directly mount the file.

# Mount/dev/sdc1/mnt/usbhd1

Mount the Windows partition when it is started. The windows D disk is automatically mounted to/mnt/D. Use VI to open/etc/fstab,

Add the following line:
/Dev/hda5/mnt/d vfat defaults, codePage = 936, iocharset = cp936 0 0
Note: You must create a/mnt/d directory manually.

Mount the directory shared by other Windows machines on the LAN (bjchenxu)
Mount-T smbfs-O username = guest, password = guest // machine/path/mnt/CDROM

3. mount a USB flash drive

Like a USB-based mobile hard drive, USB flash drives are also treated as SCSI devices for Linux systems. Use method and mobile hard disk completely

Same. Before inserting a USB flash drive, use fdisk-l or more/proc/partitions to view the hard disk and hard disk partition of the system.

After the USB flash drive is inserted, use fdisk-l or more/proc/partitions to view the hard disk and hard disk partition of the system.

Partition 1 has different physical/logical endings:

The system has a SCSI hard disk/dev/SDD and a disk partition/dev/sdd1./dev/sdd1 is the USB flash drive to be attached.

# Mkdir-P/mnt/USB
Note: create a directory for mount point)

# Mount-T vfat/dev/sdd1/mnt/USB

Note: You can now access the USB flash drive through/mnt/USB. If the Chinese character file name is garbled or not displayed, use the following command.
# Mount-T vfat-O iocharset = cp936/dev/sdd1/mnt/USB

Iv. mount Windows File Sharing

The core of Windows Network Sharing is SMB/CIFS. To mount Windows disk sharing in Linux, you must install and use the samba software package. Currently, most popular Linux distributions already contain Samba packages. If Samba is not installed on Linux, install Samba first. Of course, you can download the new version 3.0.10 from www.samba.org.

After windows sharing is configured, you can mount the file on the Linux client as follows:

# Mkdir-P/mnt/samba
Note: create a directory for mount point)

# Mount-T smbfs-o

Username = administrator, password = pldy123 // 10.140.133.23/C $/mnt/samba
Note: Administrator and pldy123 are user names and passwords of Windows computers with IP addresses 10.140.133.23, and C $ is a disk share of this computer.

In this way, files on Windows disks can be accessed through/mnt/samba on Linux.

V. mount nfs file sharing in UNIX systems

Similar to Windows Network Sharing, Unix (Linux) systems also have their own network sharing, that is, NFS (Network File System ), next we will take Sun solaris2.8 and RedHat as Server 3 as an example to briefly introduce how to mount nfs network sharing in Linux.

Before mounting an NFS disk to a Linux client, you must configure the NFS server.

1. Configure the NFS server of the Solaris system as follows:

(1) Modify/etc/dfs/dfstab to add a shared directory.

Share-F nfs-o rw/export/home/sunky

(2) Start the NFS service

#/Etc/init. d/nfs. Server start

(3) After the NFS service is started, you can also use the following command to add a new share.

# Share/export/home/sunky1

# Share/export/home/sunky2

Note:/export/home/sunky and/export/home/sunky1 are shared directories.

2. Configure the NFS server in Linux as follows:

(1) Modify/etc/exports to add a shared directory.

/Export/home/sunky 10.140.133.23 (RW)

/Export/home/sunky1 * (RW)

/Export/home/sunky2 Linux-client (RW)

Note: sunky, sunky1, and sunky2 under the/export/home/directory are the shared directories, 10.140.133.23, *, and Linux-client are IP addresses or host names allowed to connect to the shared Linux client. If you want to use the host name Linux-client, you must add the Linux-client host IP definition in the server host/etc/hosts file. The format is as follows:

10.140.133.23 Linux-Client

(2) start and stop the NFS service

/Etc/rc. d/init. d/Portmap start (Portmap is started by default in RedHat)

/Etc/rc. d/init. d/nfs start the NFS service

/Etc/rc. d/init. d/nfs stop NFS service

Note: If a new share is added to the/etc/export file, stop the NFS service and then start the NFS service to make the new share take effect. The command exportfs-RV can also achieve the same effect.

3. Mount the NFS share of other Linux or Unix systems on the Linux Client

# Mkdir-P/mnt/nfs

Note: create a directory for mount point)

# Mount-T nfs-o rw 10.140.133.9:/export/home/sunky/mnt/nfs

Note: here we assume 10.140.133.9 is the IP address of the NFS server host. Of course, the host name can also be used here, but the Server IP address definition must be added to the local/etc/hosts file. /Export/home/sunky is the directory shared by the server.

In this way, you can use/mnt/NFS on the Linux client to access files shared by NFS on other Linux or UNIX systems. The preceding operations are successfully performed in RedHat as Server 3, redflag server4.1, Suse Server 9, Solaris 7, Solaris 8, and Solaris 9 for x86 & iSCSI.
