使用git服务器的工程师都需要生成一个ssh的公钥
~/.ssh$ ssh-keygen
Generating public/private rsa key pair.
……………………
……………………
然后一律按回车，完成后会在home目录下的.ssh目录中生成两个文件id_rsa(私有密钥)和id_rsa.pub(公钥)。
将生成的公钥id_rsa.pub发给git仓库的管理者。
然后在服务器端：
sudo adduser git
su git
cd ~
mkdir .ssh
在git用户新建一个.ssh的目录，将开发者的SSH公钥添加到git这个用户的authorized_keys这个文件当中。如有zhangsan,lisi两个开发者。
cat /tmp/id_rsa_zhangsan.pub >> ~/.ssh/authorized_keys
cat /tmp/id_rsa_lisi.pub >> ~/.ssh/authorized_keys
建立一个空的仓库
cd work
mkdir project.git
cd project.git
git --bare init
使用--bare会初始化一个不带任何工作目录的仓库，不会看到工程源码。
开发者端：
若没有仓库的情况下，需要首先新建一个仓库。在需要建立仓库的，目录下执行以下的命令。
cd my_project
git init
git add . (将所有代码加入工程管理)
git commit -m "xxx project initial commit"
git remote add origin [email protected]:/home/git/work/project.git (即：用户名@网络地址:/home/git/work/project.git)
然后执行：git push origin master
如果出现以下错误：
The authenticity of host ‘localhost (::1)‘ can‘t be established.
RSA key fingerprint is eb:e3:e2:36:84:64:23:f2:b8:7b:a0:4c:ef:d4:9e:7d.
Are you sure you want to continue connecting (yes/no)?
Host key verification failed.
执行一下：$ssh localhost -o StrictHostKeyChecking=no
(用ssh登录一下就好使，就不会弹出The authenticity of host ‘localhost (::1)‘ can‘t be established.的错误了。)
然后再退出ssh登录。
然后：
[email protected]:~/linux-2.6$ git push origin master

分析 ssh localhost -o StrictHostKeyChecking=no可能不会检查公钥的正确性就让登录了。
