Use Git on Window10 to interconnect with Github remote warehouse

1. Register a Github account

2. Create a warehouse (you can also create it later, see point 9)

3. Install Git
   install Git on Windows is very simple, directly in Git official website to download the installer, and then press the default installation.

4. After the installation is complete, in the start menu bar -> All Programs, you will find Git->Git Bash
   
   as shown in the figure above, which means that the Git installation is successful!

5. Tell Git your username and email (ie your GitHub username and email), enter the following command to set
   

   Using the -global parameter is to make all Git repositories on this machine use the username and mailbox, and different repositories can also use different usernames and mailboxes. But we usually only use one GitHub account, so just set it up directly like this

6. Create a local warehouse on your own computer (a warehouse can be simply understood as a directory, and each directory contains a warehouse)

   Create a new folder (such as the E: Git/ directory) anywhere on your computer. This directory will serve as the Git management directory, and all warehouses will be created in this directory.
   

   Create a new local warehouse under this directory, named data-mining 1. cd to
   this directory
   
   2. Create a new directory data-mining, and then cd to the data-mining directory
   
   3. Change the data-mining directory into a warehouse that can be managed by Git
   
   After running this command, you can generate a hidden .git folder in the data-mining directory, indicating that the initialization is successful, and the directory can be managed by Git. For the
   above operations, we have created an empty warehouse data-mining

7. Add files to the warehouse, for example: create a new helloworld.py file in the warehouse directory, adding the file to the warehouse requires the following two steps:

   1. Use the command git add to add the file to the warehouse
   
   

   This means that the helloworld.py project file is added to the warehouse. If you want to add all files, you can also use git add. Directly add all the files in the warehouse directory to the warehouse at one time, and use the git commit command for the last time. It's a lot convenient.
   2. Use the command git commit to submit the file to the warehouse
   
   -m. The input is the description of this submission. It is better to be meaningful, so that you can easily find the change record from the history record.

8. Remote warehouse settings
   Generally speaking, we don't just build GIt warehouses locally, but the more common situation is to interconnect the local warehouses with the remote warehouse GitHub. Since SSH encryption is used, the following settings are required:

   1. Create an SSH Key. In the user's home directory, check if there is a .ssh directory. If so, check if there are two files id_rsa and id_rsa.pub in this directory. If you already have one, you can jump to it directly Next step. If not, open a terminal (open Git Bash under Windows) and create an SSH Key:
   

   Then enter the password twice again!

   2. Log in to your GitHub, click the Settings option in the upper right corner of the page, click SSH and GPG keys, click New SSH key, and enter Title and Key. Key is the content in your computer’s id_rsa.pub.pub, just copy it directly
   
   Open id_rsa.pub.pub, you can directly use the cat command to view the public key: cat id_rsa.pub.pub or vim id_rsa.pub.pub to view the local public key. The
   
   reason why you need to set the SSH key is to identify what you pushed. You pushed it, not someone impersonating it, and Git supports the SSH protocol, so as long as GitHub knows your public key, you can confirm that only you can push.
   If you have two computers, such as one at the company and one at home. Then you can add the public keys of both computers to your GitHub, so that both can be pushed.

9. Upload from local to GitHub
   Just now we have built a data-mining warehouse locally, so how to upload this warehouse to our remote warehouse GitHub?

   1. Create a new blank warehouse on GitHub and name it data-mining.
   First, click on New repository in the upper right corner of your GitHub homepage, and then write data-mining in the Repository name, don’t check "Initialize this repository with a README", just click Create repository
   
   
   2. Go back to our Git Bash interface and set the local The Git library is associated with the remote warehouse just built, enter the following command
   
   3. The next step is to upload all the files in the local warehouse to GitHub.
   git push -u origin master
   
   If there is an error, fatal: unable to access 'https://github.com/Libra-1023/data-mining.git/': error setting certificate verify locations: CAfile: D:/Git/mingw64/ssl/certs/ca-bundle.crt CApath: nonesee this article to solve it https://blog.csdn.net/sdhongjun/article/details /52144253

   

   Authorization:
   It turns out that the ladder was not used, and the ladder was used after a network error, so there is a network warning in front of the
   upload success and the above sentence is displayed.
   4. Go back to GitHub, enter the data-mining warehouse, and you will find that the helloworld.py file has been uploaded to our GitHub. On the GitHub page, you can see that the content of the remote library is exactly the same as the local one.
   
   5. After that, after we make any changes in the local data-mining warehouse, we can directly run the following statements to add, submit to the warehouse and upload to the GitHub remote warehouse.
   git add .
git commit -m "xxx"
git push -u origin master

10. Clone from GitHub to a local repository
    We have created a remote repository on GitHub. How to use Git to synchronize the repository on GitHub to the local repository?

    1. Copy the Github warehouse address
    

    2. Open Git Bash, cd to the /Git directory we created before (there is no data-mining folder in the /Git directory, ignore the operation in the previous section), enter the following command, you can directly clone the GitHub remote warehouse learngit to Locally
    git clone https://github.com/Libra-1023/data-mining.git
    can clone successfully! ! !
    In this way, a data-mining folder will appear in the /Git directory, and all files in the GitHub remote warehouse will be cloned in the /Git/data-mining/ directory (including a .git folder).
    This completes the function of cloning from the GitHub remote warehouse to the local warehouse. This method does not need to run the git init statement, just the above statement.
    After cloning, you can add files, modify projects, etc. in the local warehouse, and then use the following three statements to upload to the GitHub remote warehouse

    git add .
git commit -m "xxx"
git push -u origin master

    Generally, after entering the "git push -u origin master" statement, you need to enter your GitHub username and password. But I changed the way of submitting using https to ssh instead of entering the username and password
