linux partition steps

Linux partition prerequisites:

1. The hard disk must be partitioned, created a file system (formatted) and mounted to store data. ;

2. A hard disk can only have up to 4 primary partitions (1 extended partition is equivalent to 1 primary partition);

There can be at most 1 extended partition and multiple logical partitions. , but the maximum number of logical partitions is no more than 12, and the extended partition is equivalent to the container of the logical partition.

1. Create partitions

1. Enter the fdisk interface and list all commands

fdisk /dev/sda

2. Display hard disk partition information

command(m for help):p

3. Create the primary partition

command（m for help）： n            #创建

We need to allocate the starting and ending cylinders of partition 3. To do this, you can directly press Enter to use the default starting cylinder, or you can enter a number to specify the starting cylinder.

4. Delete the primary partition

command（m for help）： d            #删除
partition number （1-4）：3          #删除分区3
command（m for help）： p            #查看结果

Note: Do not delete sda1 and sda2!

5. Save and exit

command（m for help）： w          #保存并退出
command（m for help）： q          #不保存直接退出

2. Create file system (formatting)

1. After creating the partition, refresh it multiple times

partx -a /dev/sda           #刷新分区

2. Create a file system on the partition

mkfs -t ext3/dev/sda5      #（-t ext3指定文件系统格式）

3. Mount

1. Create a new mounting directory

mkdir /mnt/kk

2. Short-term mounting

mount /dev/sda5 /mnt/kk

3. Check the partition mounting status

mount –s           #查看所有已经挂载的分区情况
