GitHub every time Pull/push code to require the user to push code is legal, so each push time to enter the account password to verify whether the user is a legitimate user, and SSH is a secure transmission mode, can replace the user's "Enter account password" behavior to verify the user.

GitHub supports 2 different modes of operation

1. Https

   You can clone a project on GitHub at will, no matter who it is, and you need to verify your username and password at Pull/push.

2. Ssh

   The clone must be a user or administrator, and you will need to add SSH key before cloning. Instead of validating the user name and password at Pull/push, the user is authenticated by validating SSH.

The following tutorial configures an SSH connection under a Linux client

Prepare a Linux computer with access to the Internet first

In the example, Centos7 is used.

Install git using the Yum install Git-core command

Run git--version after installation is complete

Generate an SSH certificate

Ssh-keygen-t rsa-c "[Email protected]"

The-t parameter is the type of the specified key, which is specified in RSA

-C is comment I'm writing a github account here.

There will be several interactions after executing the command

1,enter file in which to save the key (/ROOT/.SSH/ID_RSA): Here you can press ENTER directly, the system will use the default name to generate the key

The name of the private key is Id_rsa, and the public key name is Id_rsa.pub

650) this.width=650; "title=" image "style=" border-left-0px; border-right-width:0px; border-bottom-width:0px; border-top-width:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M00/8E/57/ Wkiol1i-q--qvkqfaaah3fqxpwu047.png "width=" 242 "height="/>

2,enter passphrase here can also directly press ENTER, default is no password. If you enter a password (you'll have to enter it again after you enter the password), the next time you connect to GitHub, you'll be asked to enter the password (do we use SSH to not enter the password?). , so direct return)

After entering the/ROOT/.SSH, the Id_rsa.pub file is uploaded to the local open or directly to cat id_rsa.pub

Copy the contents of the key

Login to GitHub now (no account?) Of course, you have to register a first)

Enter account Setting–ssh and GPG keys

Select New SSH Key

Just type a name (easy to identify where the SSH request came from)

In the key area, paste in the content you just copied, then click "Add SSH Key"

When you are finished, you will see the following options

When you are done, go back to the Linux host to verify that SSH connection is OK

Perform

[email protected]

Are you sure you want to continue connecting (yes/no)?这里输入yes

如果出现

You‘ve successfully authenticated, but GitHub does not provide shell access. 则代表ssh连接已经成功

Back on GitHub, you can see that the sshkey you just added turns green.

Now we go back to the Linux host and try to clone a repo on GitHub.

A repo under my own account is as follows

I should have typed it under Linux.

git clone [email protected]:hzl790209/game-of-life

Start clone this repo on GitHub after entering the command

This way Linux uses SSH to connect to GitHub already configured to complete
