Git is a distributed version control software that was originally created by the Linux kernel developer Linus Torvalds to better manage Linux kernel development. So far, Git has become a fairly useful version management tool. Compared to SVN, if you want to save some minor changes must be submitted to the server to save it, so that the server's version number is too much, and git to solve the problem, some small changes can only be submitted locally,

Git has more flexibility in versioning than with SVN, and for open source projects, we can be hosted on GitHub, which is very handy, but closed-source projects charge a lot of money.So what about private projects, how do you use git for code versioning? We can build our own git servers. In general, there are many tutorials on how to build git on Linux, but how do you bu

GitHub is a remote repository that is free to host open source code. But for some depending on the source code such as life of commercial companies, neither want to open the source code, but also reluctant to give GitHub to pay protection fees, then you can only build a git server as a private warehouse to use.
