linux的VPS如何分区

1.fdisk -l

01.[root@MyVPS ~]# fdisk -l

02.Disk /dev/xvda: 8589 MB, 8589934592 bytes

03.255 heads, 63 sectors/track, 1044 cylinders

04.Units = cylinders of 16065 * 512 = 8225280 bytes

05.Device Boot      Start         End      Blocks   Id  System

06./dev/xvda1   *           1          13      104391   83  Linux

07./dev/xvda2              14        1044     8281507+  8e  Linux LVM

08. 

09.Disk /dev/xvdb: 23.6 GB, 23622320128 bytes

10.255 heads, 63 sectors/track, 2871 cylinders

11.Units = cylinders of 16065 * 512 = 8225280 bytes

12.Device Boot      Start         End      Blocks   Id  System

 

对/dev/xvdb(此名称因系统而异)进行分区：

1.fdisk /dev/xvdb

 

01.[root@MyVPS ~]# fdisk /dev/xvdb

02.The number of cylinders for this disk is set to 2871.

03.There is nothing wrong with that, but this is larger than 1024,

04.and could in certain setups cause problems with:

05.1) software that runs at boot time (e.g., old versions of LILO)

06.2) booting and partitioning software from other OSs

07.(e.g., DOS FDISK, OS/2 FDISK)

08. 

09.输入n新建分区

10.Command (m for help): n

11.Command action

12.e   extended

13.p   primary partition (1-4)

14.p

15. 

16./dev/xvdb中第1个分区

17.Partition number (1-4): 1

18.First cylinder (1-2871, default 1):

19.Using default value 1

20.Last cylinder or +size or +sizeM or +sizeK (1-2871, default 2871):

21.Using default value 2871

22. 

23.输入W保存退出

24.Command (m for help): w

25.The partition table has been altered!

26.Calling ioctl() to re-read partition table.

27.Syncing disks.

将新分区xvdb1(此名称因系统而异)格式化为ext3格式

 

1.mkfs -t ext3 /dev/xvdb1

 

01.[root@MyVPS ~]# mkfs -t ext3 /dev/xvdb1

02.mke2fs 1.39 (29-May-2006)

03.Filesystem label=

04.OS type: Linux

05.Block size=4096 (log=2)

06.Fragment size=4096 (log=2)

07.2883584 inodes, 5765319 blocks

08.288265 blocks (5.00%) reserved for the super user

09.First data block=0

10.Maximum filesystem blocks=4294967296

11.176 block groups

12.32768 blocks per group, 32768 fragments per group

13.16384 inodes per group

14.Superblock backups stored on blocks:

15.32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,

16.4096000

17.Writing inode tables: done

18.Creating journal (32768 blocks): done

19.Writing superblocks and filesystem accounting information: done

20.This filesystem will be automatically checked every 24 mounts or

21.180 days, whichever comes first.  Use tune2fs -c or -i to override.

我们示范将新分区xvdb1挂载到目录/home
因为home已经存在，所以我们挂载
mount /dev/xvdb1 /home
如果你需要挂载在别的目录.可以新建一个目录挂载.如:home1,使用如下命令:


1.mkdir /home1

2.mount /dev/xvdb1 /home1


完成后我们通过df -hal可以看到，新分区已经挂载到目录/home上了


01.[root@MyVPS ~]# df -hal

02.Filesystem            Size  Used Avail Use% Mounted on

03./dev/mapper/VolGroup00-LogVol00

04.5.7G  1.4G  4.1G  25% /

05.proc                     0     0     0   -  /proc

06.sysfs                    0     0     0   -  /sys

07.devpts                   0     0     0   -  /dev/pts

08./dev/xvda1             99M   28M   67M  30% /boot

09.tmpfs                 256M     0  256M   0% /dev/shm

10.none                     0     0     0   -  /proc/sys/fs/binfmt_misc

11.sunrpc                   0     0     0   -  /var/lib/nfs/rpc_pipefs

12./dev/xvdb1             22G  173M   21G   1% /home


最后添加开机自动挂载：

 

1.echo "/dev/xvdb1 /home ext3 defaults 1 2" >> /etc/fstab


这样就完成了！
通过后台控制系统重做系统之后,只需要重新挂载一次即可


1.mount /dev/xvdb1 /home


最后，重新添加自动挂载即可：


1.echo "/dev/xvdb1 /home ext3 defaults 1 2" >> /etc/fstab
