linux系统下挂载光盘，挂载ISO，挂载硬盘，挂载硬盘分区

linux系统下挂载光盘，挂载ISO，挂载硬盘，挂载硬盘分区

1:挂载光盘

1.1:首先光盘放到物理服务器当中，这时候linux系统就会去读取光盘的硬件信息，并且将光盘的硬件信息存放到/dev/cdrom下面

1.2:创建挂载目录

# mkdir /CD/

1.3:将光盘临时挂载到/CD目录下面

可以用一下两种方式进行挂载--------------->选其中一种方式进行挂载

# mount -t iso9660 /dev/cdrom /mnt/cdrom----------------->方式1

# mount  /dev/cdrom /mnt/cdrom----------------->方式2

1.4:挂载完了查看一下

# lsblk

1.5:将光盘永久挂载到/CD目录下面------------------->就是编写配置文件/etc/fstab

# vim /etc/fstab

/dev/cdrom /mnt/cdrom         iso9660 defaults  0 0--------------------->iso9660表示标准的cd格式

/dev/cdrom  /mnt/cdrom        ext4  defaults  0 0------------------>方式2

 

 

2:挂载ISO文件

2.1:首先创建一个/ISO目录----------->目录随便命名

#mkdir /ISO

2.2:将rhel-server-7.6-x86_64-dvd.iso镜像上传到/ISO目录下面--------->就是通过tftp工具把镜像拖到/ISO目录

2.3:下面创建挂载目录----------------->随便创建

#mkdir  /media/rhel-server-dvd1

 

2.4:下面那临时挂载光盘镜像------------------->就是编写配置文件/etc/fstab

可以用一下两种方式进行挂载--------------->选其中一种方式进行挂载

# mount -o loop  /ISO/rhel-server-7.6-x86_64-dvd.iso /media/rhel-server-dvd1---------------->方式1

# mount -o loop -t iso9660  /ISO/rhel-server-7.6-x86_64-dvd.iso  /media/rhel-server-dvd1----------------->方式2

 

2.5:挂载完了查看一下

# lsblk

 

2.6:将rhel-server-7.6-x86_64-dvd.iso永久挂载到/ISO目录下面------------------->就是编写配置文件/etc/fstab

/ISO/rhel-server-7.6-x86_64-dvd.iso /media/rhel-server-dvd1 iso9660 defaults,loop 0 0

 

 

3:挂载硬盘----------->也叫挂载磁盘

3.1:先往物理服务器里面插入一块硬盘--------------->这里已经加入了一块硬盘了

3.2:下面查看一下刚添加的磁盘有没有添加进来

# lsblk

NAME               MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT

sda                  8:0    0    80G  0 disk

|-sda1               8:1    0     8G  0 part [SWAP]

`-sda2               8:2    0    72G  0 part /

sdb                  8:16   0    50G  0 disk

`-oravg-oralv      253:1    0  48.8G  0 lvm  /oracle

sdc                  8:32   0   200G  0 disk

`-datavg-datalv    253:3    0 195.3G  0 lvm  /oradata

sdd                  8:48   0   400G  0 disk

`-backvg-backuplv  253:0    0 390.6G  0 lvm  /backup

sde                  8:64   0   200G  0 disk

`-archvg-archivelv 253:2    0 195.3G  0 lvm  /archive

sdf                  8:80   0   150G  0 disk -------------------->这是刚添加的磁盘

sr0                 11:0    1   4.2G  0 rom

 

 

3.3:新添加的磁盘是存放在/dev目录下面的

# ls /dev | grep

# ls /dev/ | grep 'sdf'

sdf

 

3.4:先格式化 /dev/sdf------------>就是先赋予磁盘文件系统

# mkfs -t ext4 /dev/sdf

3.5:下面创建挂载点

# mkdir /disk100

 

3.6:将磁盘/dev/sdf挂载到disk100

[root@DISANJD-4 ~]# mount /dev/sdf /disk100/

[root@DISANJD-4 ~]# lsblk

NAME               MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT

......

sdf                  8:96   0   150G  0 disk /disk100

 

3.7:将/dev/sdf 永久挂载到/disk100/目录下面------------------->就是编写配置文件/etc/fstab

]# vim /etc/fstab

/dev/sdf  /disk100/  ext4  defaults 0 0 -------------->写入这一行，下次开启就会自动启动

 

 

 

 

 

 

4:挂载硬盘分区

4.1:先往物理服务器里面插入一块硬盘--------------->这里已经加入了一块硬盘了

4.2:下面查看一下刚添加的磁盘有没有添加进来

# lsblk

sdg                  8:80   0   100G  0 disk -------------------->这是刚添加的磁盘

sr0                 11:0    1   4.2G  0 rom

 

4.3:下面先对/dev/sdg磁盘进行分区

[root@DISANJD-4 ~]# fdisk /dev/sdg

Welcome to fdisk (util-linux 2.23.2).

Changes will remain in memory only, until you decide to write them.

Be careful before using the write command.

Device does not contain a recognized partition table

Command (m for help): n----------------------->n新建分区,输入m表示打开帮助

Partition type:

   p   primary (0 primary, 0 extended, 4 free)----------------->linux当中一块磁盘可以风味

   e   extended------------------------>扩展分区

Select (default p): ------------------->p是主分区，e是扩展分区

Using default response p------------------->默认使用p

Partition number (1-4, default 1): 1-------------------------->这是分区编号，分区编号为1到4----------------->linux当中一块磁盘可以分4个主分区

First sector (2048-209715199, default 2048):

Using default value 2048

Last sector, +sectors or +size{K,M,G} (2048-209715199, default 209715199): 50G------------------>分区大小给50G(单位必须大写)

Value out of range.

Last sector, +sectors or +size{K,M,G} (2048-209715199, default 209715199):

Using default value 209715199

Partition 1 of type Linux and of size 100 GiB is set

Command (m for help): w-------------------------->w保存分区信息
