1.3. 查看磁盘情况（此步不建议省略）
下方红字为要创建分区的硬盘。
[root@servername ~]# fdisk -l

1.4. 创建分区
下方红字为要创建分区的硬盘注意跟上面查看到的要对应。
[root@servername ~]# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x883e515a.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').
Command (m for help): n 新增加一个分区

e extended
p primary partition (1-4)
p 分区类型我们选择为主分区
Partition number (1-4): 1 分区编号选1，如果被占依此类推
First cylinder (1-130541, default 1): 按回车 默认（起始扇区） Using default value 1
Last cylinder, +cylinders or +size{K,M,G} (1-130541, default 130541): 按回车 默认（结束扇区）也可以使用长泾中学+100M即创建100M的分区 也可以使用（K,M,G）
Using default value 130541
Command (m for help): w 写分区表（可以输入t进行分区格式调整，见1.6调整分区格式）

1.5. 重新查看磁盘情况（此步可省略）
下方红字为新创建的磁盘分区信息。
[root@servername ~]# fdisk -l
