A word programmers often say is: Programming for github.Without github, programmers can see how important it is to them.
The tool that works with github is git, in the previous chapter git installation and basic configuration on cloud servers There is also a basic introduction to it on the server.Although git can work on both ssh and https protocols, ssh is more often chosen for security and convenience.
If you use https, you need to authenticate every git push
The main content of this article is:
- ssh keygen generates public-key and private-key in asymmetric encryption
- Throw publik-key on github, as in the previous article Server efficient login configuration Same steps, but here's how to throw key s to the cloud server, and here's github.
Once you're familiar with the process, it only takes a minute to complete

Permission denied (publickey).
If you do not set the public key on github and execute the git clone command directly, you will have permission problems.
Testing connectivity using ssh-T is as follows, with a Permission denied exception.
$ git clone firstname.lastname@example.org:vim/vim.git Cloning into 'vim'... Warning: Permanently added the RSA host key for IP address '126.96.36.199' to the list of known hosts. Permission denied (publickey). fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists. # But there's a more direct command to see if you have permission $ ssh -T email@example.com Permission denied (publickey).

Generate a new ssh key
Use the command ssh-keygen to generate paired id_rsa and id_rsa.pub File, only id_after generationRsa.pubThrow it into github.
# Generate an ssh-key # -t: optional dsa | ecdsa | ed25519 | rsa | rsa1, representing encryption # -C: Notes, usually write your own mailbox $ ssh-keygen -t rsa -C "shanyue" # Generate id_rsa/id_rsa.pub: Paired private and public keys $ ls ~/.ssh authorized_keys config id_rsa id_rsa.pub known_hosts Copy Code
Add a new ssh key to the github settings
Copy ~/.ssh/id_in Cloud ServerRsa.pubThe contents of the file are pasted into the github configuration.
$ cat ~/.ssh/id_rsa.pub ssh-rsa AAAAB3SSSSSSSSSSSSSSSSSSSSSBAQDcM4aOo9qlrHOnh0+HHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHuM9cYmdKq5ZMfO0dQ5PB53nqZQ1YAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAc1w7bC0PD02M706ZdQm5M9Q9VFzLY0TK1nz19fsh2I2yuKwHJJeRxsFAUJKgrtNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN7nm6B/9erp5n4FDKJFxdnFWuhqqUwMzRa9rUfhOX1qJ1SYAWUryQ90rpxOwXt9Pfq0Y13VsWk3QQ8nyaEJzytEXG7OR9pf9zDQph4r4rpJbXCwNjXn/ThL shanyue Copy Code
In github's ssh keys settings: github.com/settings/ke... Click New SSH key to add the public key you just generated.

Successful ssh-T testing allows you to successfully and happily program to github without worrying about copying code.
$ ssh -T firstname.lastname@example.org Hi shfshanyue! You've successfully authenticated, but GitHub does not provide shell access. $ git clone email@example.com:shfshanyue/vim-config.git Cloning into 'vim-config'... remote: Enumerating objects: 183, done. remote: Total 183 (delta 0), reused 0 (delta 0), pack-reused 183 Receiving objects: 100% (183/183), 411.13 KiB | 55.00 KiB/s, done.
