git-ssh-keygen

ssh-keygen

Look at whether the local has been key

cd ~/.ssh

This folder contains two files
id_rsa - private
id_rsa.pub - public
Without these two files, then you need to regenerate (available using the following command back to overwrite the original key)

1, first set up a user name and mailbox

git config --global user.name "******"
git config --global user.email "******"

Generate ssh keys

ssh-keygen -t rsa -C "*****@qq.com"

Continuous carriage return (if it is regenerated, the intermediate need to enter y)
