Because the transfer between the local git repository and the GitHub repository is encrypted via SSH, set the
1th step: Create SSH Key. In the user home directory, see if there is no. ssh directory, if there is, then look at this directory there are no Id_rsa and id_rsa.pub these two files, if already have, can jump directly to the next step. If not, open the shell (open git Bash under Windows) and create SSH Key:
Ssh-keygen " [email protected] "
You can find the. SSH directory in the user's home directory, there are Id_rsa and id_rsa.pub two files, these two are SSH key key pair, Id_rsa is the private key, can not be disclosed, Id_rsa.pub is the public key, you can safely tell anyone.
2nd step: Login to GitHub, open "Account Settings", "SSH Keys" page:
Then, click "Add SSH Key", fill in any title, paste the contents of the Id_rsa.pub file in the Key text box
Why does GitHub need SSH key? Because GitHub needs to recognize that your push submission is actually pushed by you, not someone else impersonating it, and Git supports the SSH protocol, so if GitHub knows your public key, you can confirm that only you can push it.
Of course, GitHub allows you to add multiple keys. Assuming you have a number of computers, you can submit them at the company in a moment, and at home, just add each key to GitHub and push it to GitHub on every computer.
Finally, friends can see the Git repository, which is hosted on GitHub for free (but only you can change it). So don't put sensitive information in it.
To add a remote library
Run Git bash in the root directory of the local repository as follows
$ git Remote add origin [email protected]:zcynine/hello-world.git
After adding, the name of the remote library is origin
, this is the default for Git, or can be changed to another, but origin
this name is known as a remote library.
Next, you can push all the contents of the local library to the remote library:
$ Git push-u Origin Master
Since the remote library is empty, the first time we push master
a branch, with -u
parameters, Git will not only master
push the local branch content of the remote new master
branch, but also the local master
branch and the Remote master
Branch Association, You can simplify the command at a later push or pull.
$ GIT push origin master
Cloning from a remote library
$ git clone [email protected]:zcynine/hello-world.git
You may also notice that GitHub gives more than one address and can also use such an https://github.com/zcynine/hello-world.git
address. In fact, GIT supports a variety of protocols, git://
using SSH by default, but can also use https
other protocols.
With the https
exception of slow speed, one of the biggest problems is that each push must enter a password, but in some companies that only open HTTP ports, the protocol cannot be used ssh
https
.
Branch Branch
To view branches:git branch
To create a branch:git branch <name>
To switch branches:git checkout <name>
Create + switch Branches:git checkout -b <name>
