規(guī)劃硬盤中的分區(qū)——fdisk
fdisk [磁盤設(shè)備]
使用此命令可進(jìn)入交互操縱，您可以在下面的交互操縱里面胡作非為，但是切記離開時(shí)必須按q命令，不能按w
#找出系統(tǒng)中所在根目錄所在磁盤，并查閱該硬盤內(nèi)的相關(guān)信息
[root@localhost ~]# df / <==重點(diǎn)找出磁盤文件名而已 文件系統(tǒng) 1K-塊 已用 可用 已用% 掛載點(diǎn) /dev/hda2 9920624 2968604 6439952 32% / [root@localhost ~]# fdisk /dev/hda ==>進(jìn)入交互操縱模式，注意這里不要寫具體的數(shù)字 The number of cylinders for this disk is set to 2610. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Command (m for help): m <==等待輸入，m是命令菜單 Command action a toggle a bootable flag b edit bsd disklabel c toggle the dos compatibility flag d delete a partition ==>刪除一個(gè)分區(qū) l list known partition types ==>創(chuàng)建邏輯分區(qū) m print this menu n add a new partition ==>增加一個(gè)分區(qū) o create a new empty DOS partition table p print the partition table ==>在屏幕上顯示分區(qū)表 q quit without saving changes ==>不存儲(chǔ)，直接離開fdisk程序 s create a new empty Sun disklabel t change a partition's system id 變更分區(qū)類型 u change display/entry units v verify the partition table w write table to disk and exit ==>將剛才的操作寫入分區(qū)表，慎重操作 x extra functionality (experts only)
常見操作有：創(chuàng)建主分區(qū)、創(chuàng)建擴(kuò)展分區(qū)（將硬盤的所有剩余空間作為擴(kuò)展分區(qū)）、創(chuàng)建邏輯分區(qū)、改變分區(qū)的系統(tǒng)代碼、保存分區(qū)表信息、用partprobe探測(cè)硬盤分區(qū)變化
下面舉出幾例做測(cè)試，離開時(shí)不保存：
