SHA256:lmjU8A4k+r6liYJmENBPM/7Frx3XDg98VeWvIQ9dLyw xxxxx@xxxxx.com
The key's randomart image is:
+---[RSA 2048]----+

Press enter all the way, and the output is as shown in the figure

2, Copy public key to gitee or github

$ cat id_rsa.gitee.pub
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDZbvgUEj3XAXH4HkW27ibdXgV6VHdrA9/WdSDHtiiC55mjPvxj3OtPxIbpeJmhWyHiJWR6

View the public key, enter id_rsa.gitee.pub for gitee, and enter id_rsa.github.pub for GitHub

Copy the second line to the end to the ssh of gitee or github to save

3, Create configuration to resolve ssh conflict

Create the config file in the. ssh folder and add the following to distinguish the two ssh key s

# gitee
Host gitee.com
HostName gitee.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa.gitee

# github
Host github.com
HostName github.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa.github

4, Test connection

input

$ ssh -T git@gitee.com

If you return to the figure below, the connection of gitee is normal
