Linux Disk partitioning

Disk partitions are: Primary partition, extended partition, logical partition

A hard disk can have up to 4 partitions, and a hard disk must have only one extended partition (cannot be used)

Multiple logical partitions must be partitioned and formatted in this extended partition.

Formatting: Creating a file system

File system: A mechanism for storing data

Linux is accessed by device name and is typically stored under the/dev directory

Linux partitioning scheme

Normal system-to-partition:

1. At least one/partition

2. Swap swap partition

3. Setting up a separate/boot partition is recommended
   

DB and storage: There's a lot of important data

1./50-200g

2.swap 1.5 times times

3./boot 100M

4./data/remaining hard disk size, all for storing data

Portal:

1./50-200g

2.swap 1.5 times times

3./boot 100M

Others are no longer partitioned, to be preserved, which need to be re-divided in the future

Generally not necessary partition:/usr/home/var

In the production environment: soft raid and LVM on-line adjustment partition performance is poor, generally do not use!

Hardware RAID is recommended, combined with multiple drives to expand
