Prerequisites: need your own server (nonsense nag about - -!)
Server systems: CentOS 7, ssh remote login server will not be left out of what Baidu slightly
Service-Terminal
Step 1: Install git
yum install -y git
After the installation is complete
Step two: Add a user and password to use git
useradd git #git your username does not like to define its own, but after the definition, must be replaced by the following git your user name corresponding!
passwd git # new user password must not skip this step, skip clone back when you are prompted to enter the password is! ! 8-digit password you want more!
Tip: passwd:. All authentication tokens updated successfully proved successful password
Step 3: Create a git repository
Select a directory as your warehouse such as / srv
cd / srv # to enter the Loft directory
git init --bare aa.git # initialize the project test directory
But the owner of the directory is not a git user, we have to change it to git users:
chown -R git: git aa.git # change user owner, after the change:
Server-side work being done, to the following clients:
Client
Step 1: Install git software https://git-scm.com/downloads , all the way to the next can be installed complete
After the installation is complete, open git
The second step, set your local user name and email address:
git config --global user.name "myname"
git config --global user.email "[email protected]"
第三步，生成公私钥：
ssh-keygen -t rsa -C "[email protected]" 然后一直按enter；知道出现成功的图案：
id_rsa.pub你面的内容就是我们本电脑的公钥
复制该密钥到服务器端的/home/git/.ssh/authorized_keys文件中
注意：！！！！在/home/git/目录下ls -al 查看是否有.ssh目录！！
如果没有，自己新建一个.ssh目录和authorized_keys文件：
mkdir .ssh #创建目录
chown -R git:git .ssh #修改拥有者
cd .ssh
touch authorized_keys #创建keys文件
chmod 700 authorized_keys #修改文件权限
chown -R git:git authorized_keys#修改文件拥有者
第四步:把客户端电脑生成的密钥复制到authorized_keys文件中:
vim authorized_keys
然后按a，插入密钥，然后按ESC键，再输入 :wq 保存退出(也可以用winscp或者其他编辑器把密钥添加进去)
注意！！每个密钥占一行，如果想添加多个客户端电脑需要换行再添加下一个用户！
设置基本完成了，下面进行验证：
git clone git@服务器地址:/srv/aa.git
出现下面提示证明成功了，注意:可能第一次clone 需要密码，成功之后就不需要每次输入密码，如果每次clone 或者push都需要密码肯定上面某个步骤错了，或者git用户权限不够，密钥填写格式错误，密钥文件和.ssh放置的目录不正确，要仔细检查一下。
