来一发CentOS对新到场的硬盘格局化

如果您觉得本篇CentOSLinux教程讲得好，请记得点击右边漂浮的分享程序，把好文章分享给你的小伙伴们！起首，对新到场的硬盘格局化。
步调1:

复制代码代码示例:

2)bootingandpartitioningsoftwarefromotherOSs

Command(mforhelp):w

步调3:

复制代码代码示例:
[root@rac1~]#fdisk-l
Disk/dev/sda:10.7GB,10737418240bytes
255heads,63sectors/track,1305cylinders
Units=cylindersof16065*512=8225280bytes
DeviceBootStartEndBlocksIdSystem
/dev/sda1*11147921324683Linux
/dev/sda211481305126913582Linuxswap
Disk/dev/sdb:10.7GB,10737418240bytes
255heads,63sectors/track,1305cylinders
Units=cylindersof16065*512=8225280bytes
DeviceBootStartEndBlocksIdSystem
/dev/sdb111305104823815Extended

步调4格局化分区

复制代码代码示例:
[root@rac1~]#mkfs-text3-c/dev/sdb1
mke2fs1.35(28-Feb-2004)
Filesystemlabel=
OStype:Linux
Blocksize=4096(log=2)
Fragmentsize=4096(log=2)
1310720inodes,2620595blocks
131029blocks(5.00%)reservedforthesuperuser
Firstdatablock=0
Maximumfilesystemblocks=2684354560
80blockgroups
32768blockspergroup,32768fragmentspergroup
16384inodespergroup
Superblockbackupsstoredonblocks:
32768,98304,163840,229376,294912,819200,884736,1605632

Creatingjournal(8192blocks):done
Writingsuperblocksandfilesystemaccountinginformation:done
Thisfilesystemwillbeautomaticallycheckedevery25mountsor
180days,whichevercomesfirst.Usetune2fs-cor-itooverride.

步调5:创立目次然后将该分区加挂到该目次下

复制代码代码示例:
[root@rac1/]#mkdir/u01
[root@rac1/]#mount/dev/sdb1/u01

步调6:修正/etc/fstab文件增加以下纪录使体系每次重启后都能主动加载该分区
步调7:
[root@rac1/]#vi/etc/fstab
在文件的开端填加以下内容
/dev/sdb1/u01ext3defaults12
申明:
若新加硬盘的时分选择了创立逻辑盘(即选择了e)的时分,格局话的时分会报以下毛病:

复制代码代码示例:
mkfs-text3-c/dev/sdb1
Invalidargumentpassedtoext2librarywhilesettingupsuperblock.

这是由于我们这里只创立了逻辑盘,没有创立逻辑分区,以是创立完逻辑盘后还必要创立逻辑分区:

复制代码代码示例:
[root@jbxueoracle]#fdisk/dev/sdb
Thenumberofcylindersforthisdiskissetto2088.
Thereisnothingwrongwiththat,butthisislargerthan1024,
andcouldincertainsetupscauseproblemswith:

不同于Windows?系统需要花钱购买，因为Linux的核心是免费的，自由使用的，核心源代码是开放的。

我学习Linux的心得体会 ，希望对大家的学习有所帮助，由于水平有限，本文难免有所欠缺，望请指正。

随着Linux技术的更加成熟、完善，其应用领域和市场份额继续快速增大。目前，其主要应用领域是服务器系统和嵌入式系统。然而，它的足迹已遍布各个行业，几乎无处不在。

尽量不要提问纯属是扯蛋.学习Linux特别是自己一个人初学入手的时候没人教很困难.当然如果可以的话平时多去买些Linux书...对学习Linux很有帮助.

通过自学老师给的资料和向同学请教，掌握了一些基本的操作，比如挂载优盘，编译程序，在Linux环境下运行，转换目录等等。学了这些基础才能进行下面的模拟OS程序。?

得到到草率的回答或者根本得不到任何Linux答案。越表现出在寻求帮助前为解决问题付出的努力，你越能得到实质性的帮助。

其中不乏很多IT精英的心血。我们学透以后更可以做成自己的OS！?

我想即使Linux高手也很难快速准确精练的回答你。
