设置Git服务器

通常的做法是设置Git服务器以简化Git存储库。 创建Git服务器涉及的步骤包括：

1. Dedicate a server to Git.
2. Install Git.
3. Create a git user.
4. Copy your secure shell (SSH) public keys into authorized keys for git user.
5. Initialize a bare repository on the server.
6. Clone the repository from your desktop.
7. Check in files in the repository.
8. Push the repository back to the server.

# yum install git –y
# useradd git
# su - git
$ mkdir .ssh
$ cd .ssh
$ cat <your-ssh-public-key> >> authorized_keys
$ cd $HOME
$ mkdir postfix.git
$ cd postfix.git
$ git -–bare init
$ exit
# su – <your-user-name>
$ git clone git@localhost:/home/git/postfix.git
$ touch myfile
$ git add myfile
$ git commit –am “initial commit”
$ git push origin master
