Ubuntu system disk partition scheme design and practical experience sharing

As an open source operating system, Ubuntu is very popular on both servers and personal computers. Disk partitioning is a very important step when installing Ubuntu. A reasonable disk partitioning scheme can improve the performance and stability of the system. At the same time, you can better manage data and files. This article will share some experience in the design and practice of Ubuntu system disk partitioning scheme, and how to partition the disk on Ubuntu 20.04.

Ubuntu 20.04 Disk Partitioning

Ubuntu 20.04 is the latest long-term support version, it introduces many new features and improvements, before doing disk partitioning, we First you need to understand some basic concepts.

1. Primary partition and extended partition:

The primary partition is the partition used to install the operating system. Each disk can have up to 4 primary partitions. The extended partition is a special primary partition. , which can be divided into multiple logical partitions.

2. File system:

The file system refers to a way that the operating system uses to organize and manage files. In Ubuntu, commonly used file systems include EXT4, NTFS and FAT32, etc.

3. Mount point:

Mount point refers to the process of associating a disk partition with a specific directory in the file system. Common mount points include / (root directory), /home (user's home directory) and /swap (swap partition), etc.

When partitioning Ubuntu 20.04 disks, the following are some commonly used solutions and practical experiences:

1. Partition scheme design:

According to actual needs and hardware configuration, you can Design different partition schemes. It is generally recommended to separate the root partition and /home partition to preserve user data when the system crashes or is reinstalled. You can also consider creating a swap partition for temporary storage when the system memory is insufficient.

2. Partition size setting:

The size of the root partition should be reasonably estimated based on the software and data required by the system, and at least 20GB of space is required. The size of the /home partition depends on the user's needs and can be adjusted according to the actual situation. The size of the swap partition should be set according to the system's memory size. It is generally recommended to set it to 1.5 times the memory size.

3. File system selection:

EXT4 is Ubuntu’s default file system, with better performance and stability. If you need to share data with Windows systems, you can choose NTFS or FAT32 files. system.

4. Mount point setting:

When installing Ubuntu, you can choose different mount points. The mount point of the root partition should be set to /, the mount point of the /home partition. It should be set to /home and the mount point of the swap partition should be set to /swap.

A reasonable disk partition scheme can improve the performance and stability of the Ubuntu system, and can also better manage data and files. On Ubuntu 20.04, we can design the disk partition according to actual needs and hardware configuration. , by setting the partition size appropriately and choosing the appropriate file system and mount point, we can create an efficient and reliable Ubuntu system.

Share a little LINUX knowledge with you:

In the Linux system, we can use the "df" command to check the disk space usage. Through the "df -h" command, we can Display the size of the disk space in a human-readable way. This command can help us understand the disk usage of the system in time for timely adjustment and optimization.
