Create a small ssh-based local git server on the old Dell Computer

Hardware condition: Dell poweredge 745 Core 2 64-bit 1g memory 160g hard disk Ubuntu 12.04.5 lts 32-bit (because the memory is less than 2g), character interface (do not run X Windows, to save memory) Step: 1. Create a user git, create a home directory, modify the permissions as appropriate; 2. Refer to the steps in http://git-scm.com/book/zh/ section 4.2, execute: $ git clone -- bare https://github.com/ricky-gong/mongo.git (five in total) tried it. If you have SSH permission, you can transfer files with the host on your laptop. For example: $ git clone [user] @ [git.example.com]: [/opt/git/my_project.git] user name host domain name or address path of git Warehouse 3. Reference: description of the SSH key in section 4.3 of the http://git-scm.com/book/zh/; steps to generate an SSH key in the https://help.github.com/articles/generating-ssh-keys; how to transition from HTTPS to SSH in the https://help.github.com/articles/changing-a-remote-s-url (HTTPS is used at the beginning ); most of them follow the above steps, but there is one thing to modify: In the step of the second web page, run the first command in step 2:

Ssh-keygen-t rsa-c"[Email protected]"
It requires you to enter passphrase next to it. We strongly recommend that you enter passphrase on this webpage. However, because of our special environment, press enter directly. Otherwise, passphrase will be entered for each upload, SSH has no advantages over HTTPS.
Others.
========================================================== ==============================================
Cause:
The most fundamental reason is that we work on the Character interface.
Theoretically, this passphrase will be saved by an SSH-Agent Program (automatically started upon installation, every time we transmit data through SSH and GitHub, it will automatically help us input passphrase. However, you can see from man page that the program runs on X Windows. That is to say, in the character interface, this program cannot work (so the above "start automatically ", it should be changed to "auto start after X Windows is started "). This program does not work, and the input passphrase cannot be saved, which leads to a problem I encountered before: This passphrase is required for each upload. If passphrase is not entered here, the file can be uploaded automatically.
If you accidentally input, it does not matter, do not need to re-generate a copy, just need to be in the key generated, execute the command under the page https://help.github.com/articles/working-with-ssh-key-passphrases, modify passphrase just fine.
========================================================== ==============================================
4. Write an upload script as needed and set the crontab to synchronize it with GitHub once every week and save the logs. Complete ~

Attach a shell script to check whether the host can access the Internet:

In my script program, the code above is used.


Add the source code and modify the address parameters in the upload script according to the actual directory where the two are located. Create a New log folder to store logs and modify the address parameters in upload.
