1. Operation on Linux backup data 1. First connect to the server with XSHELL and then wait for the connection
2. Enter cd/www/web/xingxilou_net/public_html2 to package the directory public_html2
3. Then execute tar zcvf a1.tar.gz/www/web/xingxilou_net/public_html to compress the directory public_html2 into gz format
4. The a1.tar.gz name needs to be changed every time it is backed up, such as 1.tar.gz
5. After the command is executed, use your website domain name and the name of the backup compressed package directly!
First, remote SSH logs in to the CentOS server and performs the following operations. Friendly prompt: The data will be cleared during the mount operation. Please make sure that the mount disk has no data or is not used before the operation.
1. Enter the command: ll /dev/disk/by-path List all disks
Tip: If you cannot confirm the device name of the data disk, use the df command to confirm the name of the system disk, so as to exclude the wrong disk.
2. Command: fdisk /dev/sdb Format hard disk
Note: Continue to type manually at the arrow mark in the figure
3. Command: mkfs.ext4 /dev/sdb1 Create partition
4. Command: mkdir /www Mount the partition (the directory name is optional)

Write the information into the fstab to enable the system to automatically mount.
