This article mainly explains "how Linux mounts disks". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let Xiaobian take you to learn "Linux how to mount disks"!

mount command

First of all, introduce the mount (mount) command use method, mount command parameters are very many, here we mainly talk about today we want to use.

Command format: mount [-t vfstype] [-o options] device dir1, -t vfstype Specifies the type of file system, usually without specifying it, mount automatically selects the correct type.

CD or CD mirror: iso9660 DOS fat16 file system: msdos Windows 9x fat32 file system: vfat Windows NT ntfs file system: ntfs Mount Windows file network share: smbfs UNIX(LINUX) file network share: nfs2, -o options is mainly used to describe the attachment method of devices or files.

loop: used to mount a file as a hard disk partition ro: mount the device read-only rw: mount the device read-write iocharset: specify the character set used to access the file system device to mount. 4. dir Mount point of device on system.

mount disc image file

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

#cp/dev/cdrom/home/sunky/mydisk.iso or #dd if=/dev/cdrom of=/home/sunky/mydisk.iso Note: Executing any of the above commands can make the CD image file/home/sunky/mydisk.iso from the current CD drive

2. Make the files and directories into CD image files and execute the following commands.

#mkisofs -r -J -V mydisk -o/home/sunky/mydisk. iso/home/sunky/ mydir Note: This command makes all directories and files in/home/sunky/mydir directory into CD image file/home/sunky/mydisk.iso, CD label: mydisk

3. Mount the CD image file

#mkdir /mnt/vcdrom Note: Create a directory for mount points

#mount -o loop -t iso9660/home/sunky/mydisk. iso/mnt/vcdrom Note: Use/mnt/vcdrom to access all files in the disk image file mydisk.iso.

Attach removable hard disk

For Linux systems, USB removable hard disks are treated as SCSI devices. Before inserting a removable hard drive, check the system's hard drive and hard drive partitions using fdisk-l or more /proc/partitions.

[root at pldyrouter /]# fdisk -l After connecting the removable hard disk, use fdisk-l or more. /proc/partitions Looking at the system's hard disks and hard disk partitions, you should find an extra SCSI hard disk/dev/sdc and its two disk partitions/dev /sdc1,/dev/sdc2, where/dev/sdc5 is the logical partition of/dev/sdc2 partition, we can use the following command to mount/dev/sdc1 and/dev/sdc5

#mkdir -p /mnt/usbhd1 #mkdir -p /mnt/usbhd2 Note: Create directories to be mount points

#mount -t ntfs /dev/sdc1/mnt/usbhd1 #mount -t vfat /dev/sdc5/mnt/usbhd2 Note: Use the-t ntfs parameter for ntfs formatted disk partitions and the-t vfat parameter for fat32 formatted disk partitions. If the Chinese character file name is displayed as garbled or not displayed, the following command format can be used.

#mount -t ntfs -o iocharset= cp936/dev/sdc1/mnt/usbhd1 #mount -t vfat -o iocharset= cp936/dev/sdc5/mnt/usbhd2Linux system using the fdisk partition command and mkfs file system creation command can be mobile hard disk partition made into linux system specific ext2, ext3 format. This makes it easier to use Linux. Use the following command to hook directly.

#mount /dev/sdc1 /mnt/usbhd1 mount USB flash drive

And USB interface of the mobile hard disk is the same for linux systems U disk is also treated as SCSI devices. Use exactly the same method as removable hard disks. Before inserting the USB drive, check the system's hard drive and hard drive partitions with fdisk-l or more /proc/partitions.

[root at pldyrouter root]# fdisk -l After inserting the USB drive, use fdisk-l or more /proc/partitions to view the system's hard disk and hard disk partitions.

[root at pldyrouter root]# fdisk -l The system has an extra SCSI hard disk/dev/sdd and a disk partition/dev/sdd1, where/dev/sdd1 is the USB drive we want to attach.

#mkdir -p /mnt/usb Note: Create a directory for mount points

#mount -t vfat /dev/sdd1/mnt/usb Note: You can now access USB drives via/mnt/usb. If Chinese file names are displayed as garbled characters or not displayed, you can use the following command.

#mount -t vfat -o iocharset= cp936/dev/sdd1 /mnt/usb Mount Windows File Sharing

The core of Windows network sharing is SMB/CIFS. To mount Windows disk sharing under Linux, you must install and use samba software package. Most popular linux distributions now include samba packages. If samba is not installed when installing linux, install samba first. You can download the new version at www. samba. org. It's version 3.0.10. When the Windows system sharing is set, you can mount it on the Linux client. The specific operations are as follows:

# mkdir-p /mnt/samba Note: Create a directory for mount points

# mount -t smbfs -o username=administrator,password=pldy123//10.140.133.23/c $ /mnt/samba Note: administrator and pldy123 are a username and password for a windows computer with ip address 10.140.133.23, and c$is a disk share for this computer. This allows you to access files on Windows disks via/mnt/samba on Linux. The above operations are tested in redhat as server3, redflag server 4.1, suse server 9 and windows NT 4.0, windows 2000, windows XP, windows 2003 environments.

Attach UNIX System NFS File Share

Similar to Windows network share, UNIX(Linux) system also has its own network share, that is NFS(network file system), the following we take SUN Solaris 2.8 and REDHAT as server 3 as an example to briefly introduce how to mount nfs network share under Linux. Before linux clients can mount NFS disk shares, the NFS server must be configured.

1. Solaris NFS server configuration method is as follows:

(1)Modify/etc/dfs/dfstab to add shared directories

share -F nfs -o rw /export/home/sunky(2) Start nfs service

# /etc/init.d/nfs.server start(3) After the NFS service is started, you can also add new shares using the following command

# share /export/home/sunky1 # share /export/home/sunky2 Note: /export/home/sunky and/export/home/sunky1 are directories ready to share

2. Linux NFS server configuration method is as follows:

(1)Modify/etc/exports to add shared directories

/export/home/sunky 10.140.133.23 (rw) /export/home/sunky1 *(rw) /export/home/sunky2 linux-client(rw) Note: sunky, sunky1, sunky2 in/export/home/directory are directories to be shared, and 10.140.133.23, *, linux-client are IP addresses or host names that are allowed to mount this shared Linux client. To use the host name linux-client, you must add the linux-client host ip definition to the server host/etc/hosts file. Format:

10.140.133.23 linux-client(2) Starting and stopping NFS services

/etc/rc.d/init.d/portmap start (PORTMAP is started by default in REDHAT) /etc/rc.d/init.d/nfs start start NFS service/etc/rc.d/init.d/nfs stop NFS service Note: If modifying/etc/export file to add new shares, you should stop NFS service first and then start NFS service to make the new shares work. The same effect can be achieved with the command exportfs -rv.

Linux clients mount NFS shares on other Linux systems or UNIX systems

# mkdir-p /mnt/nfs Note: Create a directory for mount points

#mount -t nfs -o rw 10.140.133.9:/export/home/sunky Note: Here we assume that 10.140.133.9 is the host IP address of the NFS server. Of course, the host name can also be used here, but the server IP definition must be added to the local/etc/hosts file./ export/home/sunky is a directory shared by servers. In this way, you can access files shared by other Linux systems or UNIX systems in NFS mode through/mnt/nfs on the Linux client. The above operations are tested in redhat as server 3, redflag server 4.1, suse server 9, Solaris 7, Solaris 8, Solaris 9 for x86 & sparc environments.

Additional:

Linux loading optical drive: (1) Before using optical drive, you must mount it first:

#mount /dev/cdrom /mnt/cdrom Then you can go to/mnt/cdrom and read the CD contents. (2) When you want to exit the CD, you must use the umout command, otherwise the CD drive will always be in a deadlock state:

#mount/mnt/cdrom At this point, I believe that everyone has a deeper understanding of "how Linux mounts disks", so let's actually operate it! Here is the website, more related content can enter the relevant channels for inquiry, pay attention to us, continue to learn!
