1. Partition Information
1.1/boot partition this partition contains the kernel of the operating system and the files to be used during system startup. If there is a separate/boot partition, even if a problem occurs with the primary root partition, the computer can still start. The partition size does not need to be too large to 1 GB.
1.2/home partition (recommended) This partition mainly stores your own private data. If you have a separate/home partition, you only need to format the root partition to retain the data in/home if the system is faulty or you need to reinstall the system.
1.3/swap partition (recommended) is generally twice your machine memory.
When the system's physical memory is insufficient, you need to release a portion of the physical memory for use by the currently running program. The released space may come from some programs that haven't been operated for a long time. The released space is temporarily saved to the swap space and will be executed by those programs, then, the stored data is restored from SWAp to the memory. In this way, the system always performs swap switching when the physical memory is insufficient. In fact, swap adjustment is crucial to the performance of Linux servers, especially Web servers. By adjusting swap, the system performance bottleneck is sometimes crossed to save system upgrade costs.
1.4/root partition is equivalent to the total folder of the Linux system. The root directory contains many important subset directories. Other directories can be partitioned separately or not separately. Only one directory is retained. In this way, these directories are automatically created under the root directory.
2. the partition scheme "/", and "Swap"/","/Home ","/swap "separate user documents and make it easy to back up personal files. (recommended) "/", "Swap", "home", and "USR" separate user documents and setup programs, making it easy to back up personal documents and common software.
1. make sure there are enough partitions. Use a USB flash drive or a CD to enter the Ubuntu installation interface. 2. select language 3. click to install the system (networking is not recommended, and data sources are updated quickly after configuration) 4. select "Other Options" to manually create and adjust partitions. 5. Add a partition to an idle disk and click "+" Attach "/" (ext4) to add a root partition. 20 GB is enough. 6. Similarly, add a "/swap" partition with twice the memory capacity. 7. Add the "/home" (ext4) partition, and the remaining capacity is assigned to/home. 8. Select the root partition and click Next 9. Tea ------- tea 10. Restart to complete the installation.
