在windows中安装好硬盘之后我们只要分区与格式化就可以了,但在linux中还要多一步硬盘挂载了,下面本文章就全面的介绍linux下安装一块磁盘的过程,其实就包括了硬盘分区 格式化 挂载,希望文章能帮助到各位.
1.添加磁盘,查看磁盘状况,代码如下:
- [root@db1 /]# fdisk -l
- Disk /dev/sda: 10.7 GB, 10737418240 bytes
- 255 heads, 63 sectors/track, 1305 cylinders
- Units = cylinders of 16065 * 512 = 8225280 bytes
- Device Boot Start End Blocks Id System
- /dev/sda1 * 151 1305 9277537+ 83 Linux
- /dev/sda2 1 150 1204843+ 82 Linux swap
- Partition table entries are not in disk order
- Disk /dev/sdb: 5368 MB, 5368709120 bytes
- 255 heads, 63 sectors/track, 652 cylinders
- Units = cylinders of 16065 * 512 = 8225280 bytes
- Device Boot Start End Blocks Id System
从查询结果看出,多了一个/dev/sdb的盘.
2.用fdisk 对/dev/sdb 进行分区,代码如下:
- [root@db1 /]# fdisk /dev/sdb
- Command (m for help): n
- Command action
- e extended
- p primary partition (1-4)
- p
- Partition number (1-4): 1
- First cylinder (1-652, default 1):
- Using default value 1
- Last cylinder or +size or +sizeM or +sizeK (1-652, default 652):
- Using default value 652
- Command (m for help): w
- The partition table has been altered!
- Calling ioctl() to re-read partition table.
- Syncing disks.
再次查看分区情况,多出来一个/dev/sdb1 的区,这个1是我们在前面指定的,如果我们指定2,就变成 sdb2了,代码如下:
- [root@db1 /]# fdisk -l
- Disk /dev/sda: 10.7 GB, 10737418240 bytes
- 255 heads, 63 sectors/track, 1305 cylinders
- Units = cylinders of 16065 * 512 = 8225280 bytes
- Device Boot Start End Blocks Id System
- /dev/sda1 * 151 1305 9277537+ 83 Linux
- /dev/sda2 1 150 1204843+ 82 Linux swap
- Partition table entries are not in disk order
- Disk /dev/sdb: 5368 MB, 5368709120 bytes
- 255 heads, 63 sectors/track, 652 cylinders
- Units = cylinders of 16065 * 512 = 8225280 bytes
- Device Boot Start End Blocks Id System
- /dev/sdb1 1 652 5237158+ 83 Linux
- [root@db1 /]#
3.格式化 /dev/sdb1 分区,代码如下:
- [root@db1 /]# mkfs -t ext3 /dev/sdb1
- mke2fs 1.35 (28-Feb-2004)
- Filesystem label=
- OS type: Linux
- Block size=4096 (log=2)
- Fragment size=4096 (log=2)
- 655360 inodes, 1309289 blocks
- 65464 blocks (5.00%) reserved for the super user
- First data block=0
- Maximum filesystem blocks=1342177280
- 40 block groups
- 32768 blocks per group, 32768 fragments per group
- 16384 inodes per group
- Superblock backups stored on blocks:
- 32768, 98304, 163840, 229376, 294912, 819200, 884736
- Writing inode tables: done
- Creating journal (8192 blocks): done
- Writing superblocks and filesystem accounting information: done
- This filesystem will be automatically checked every 30 mounts or
- 180 days, whichever comes first. Use tune2fs -c or -i to override.
4.创建目录 并将 /dev/sdb1 挂在到该目录下,代码如下:
- [root@db1 /]# ls
- backup dev initrd media opt sbin sys usr
- bin etc lib misc proc selinux tftpboot var
- boot home lost+found mnt root srv tmp
- [root@db1 /]# mkdir /u01
- [root@db1 /]# ls
- backup dev initrd media opt sbin sys u01
- bin etc lib misc proc selinux tftpboot usr
- boot home lost+found mnt root srv tmp var
- [root@db1 /]# mount /dev/sdb1 /u01
5.验证挂载是否成功,代码如下:
- [root@db1 /]# df -k
- Filesystem 1K-blocks Used Available Use% Mounted on
- /dev/sda1 9131772 7066884 1601012 82% /
- none 454256 0 454256 0% /dev/shm
- /dev/sdb1 5154852 43040 4849956 1% /backup
6.设置开机自动挂载,代码如下:
- [root@db1 /]# vi /etc/fstab
- # This file is edited by fstab-sync - see ’man fstab-sync’ for details
- LABEL=/ / ext3 defaults 1 1
- none /dev/pts devpts gid=5,mode=620 0 0
- none /dev/shm tmpfs defaults 0 0
- none /proc proc defaults 0 0
- none /sys sysfs defaults 0 0
- LABEL=SWAP-sda2 swap swap defaults 0 0
- /dev/sdb1 /u01 ext3 defaults 0 0
- /dev/hdc /media/cdrom auto pamconsole,exec,noauto,m
- anaged 0 0 --phpfensi.com
- /dev/fd0 /media/floppy auto pamconsole,exec,noauto,m
- anaged 0 0
