Linux系统硬盘分区 格式化 挂载的方法

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:

1. [root@db1/]#fdisk-l
2. Disk/dev/sda:10.7GB,10737418240bytes
3. 255heads,63sectors/track,1305cylinders
4. Units=cylindersof16065*512=8225280bytes
5. DeviceBootStartEndBlocksIdSystem
6. /dev/sda1*15113059277537+83Linux
7. /dev/sda211501204843+82Linuxswap
8. Partitiontableentriesarenotindiskorder
9. Disk/dev/sdb:5368MB,5368709120bytes
10. 255heads,63sectors/track,652cylinders
11. Units=cylindersof16065*512=8225280bytes
12. DeviceBootStartEndBlocksIdSystem

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:

1. [root@db1/]#fdisk/dev/sdb
2. Command(mforhelp):n
3. Commandaction
4. eextended
5. pprimarypartition(1-4)
6. p
7. Partitionnumber(1-4):1
8. Firstcylinder(1-652,default1):
9. Usingdefaultvalue1
10. Lastcylinderor+sizeor+sizeMor+sizeK(1-652,default652):
11. Usingdefaultvalue652
13. Command(mforhelp):w
14. Thepartitiontablehasbeenaltered!
16. Callingioctl()tore-readpartitiontable.
17. Syncingdisks.

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:

1. [root@db1/]#fdisk-l
3. Disk/dev/sda:10.7GB,10737418240bytes
4. 255heads,63sectors/track,1305cylinders
5. Units=cylindersof16065*512=8225280bytes
6. DeviceBootStartEndBlocksIdSystem
7. /dev/sda1*15113059277537+83Linux
8. /dev/sda211501204843+82Linuxswap
9. Partitiontableentriesarenotindiskorder
11. Disk/dev/sdb:5368MB,5368709120bytes
12. 255heads,63sectors/track,652cylinders
13. Units=cylindersof16065*512=8225280bytes
15. DeviceBootStartEndBlocksIdSystem
16. /dev/sdb116525237158+83Linux
17. [root@db1/]#

3.格式化 /dev/sdb1 分区,代码如下:

1. [root@db1/]#mkfs-text3/dev/sdb1
2. mke2fs1.35(28-Feb-2004)
3. Filesystemlabel=
4. OStype:Linux
5. Blocksize=4096(log=2)
6. Fragmentsize=4096(log=2)
7. 655360inodes,1309289blocks
8. 65464blocks(5.00%)reservedforthesuperuser
9. Firstdatablock=0
10. Maximumfilesystemblocks=1342177280
11. 40blockgroups
12. 32768blockspergroup,32768fragmentspergroup
13. 16384inodespergroup
14. Superblockbackupsstoredonblocks:
15. 32768,98304,163840,229376,294912,819200,884736
17. Writinginodetables:done
18. Creatingjournal(8192blocks):done
19. Writingsuperblocksandfilesystemaccountinginformation:done
21. Thisfilesystemwillbeautomaticallycheckedevery30mountsor
22. 180days,whichevercomesfirst.Usetune2fs-cor-itooverride.

4.创建目录 并将 /dev/sdb1 挂在到该目录下,代码如下:

1. [root@db1/]#ls
2. backupdevinitrdmediaoptsbinsysusr
3. binetclibmiscprocselinuxtftpbootvar
4. boothomelost+foundmntrootsrvtmp
5. [root@db1/]#mkdir/u01
6. [root@db1/]#ls
7. backupdevinitrdmediaoptsbinsysu01
8. binetclibmiscprocselinuxtftpbootusr
9. boothomelost+foundmntrootsrvtmpvar
10. [root@db1/]#mount/dev/sdb1/u01

5.验证挂载是否成功,代码如下:

1. [root@db1/]#df-k
2. Filesystem1K-blocksUsedAvailableUse%Mountedon
3. /dev/sda191317727066884160101282%/
4. none45425604542560%/dev/shm
5. /dev/sdb151548524304048499561%/backup

6.设置开机自动挂载,代码如下:

1. [root@db1/]#vi/etc/fstab
2. #Thisfileiseditedbyfstab-sync-see’manfstab-sync’fordetails
3. LABEL=//ext3defaults11
4. none/dev/ptsdevptsgid=5,mode=62000
5. none/dev/shmtmpfsdefaults00
6. none/procprocdefaults00
7. none/syssysfsdefaults00
8. LABEL=SWAP-sda2swapswapdefaults00
9. /dev/sdb1/u01ext3defaults00
10. /dev/hdc/media/cdromautopamconsole,exec,noauto,m
11. anaged00--phpfensi.com
12. /dev/fd0/media/floppyautopamconsole,exec,noauto,m
