Git是一个开源的分布式版本控制系统，它在全球范围内得到广泛的使用。互联网上还有像GitHub这样的网站提供了免费的Git服务，很多流行的开源项目都使用了Git来托管项目，比如Perl、Ruby on Rails、Linux内核项目等。 

在Ubuntu系统上安装Git的最佳方式是使用Ubuntu软件仓库提供的软件包，这些软件包都是经过了充分测试的，已经完成了预编译，安装或卸载都非常方便。
下面我们将在线更新服务器上的软件仓库索引，保证安装的Git服务器是比较新的稳定版。

1、升级系统并更新库索引

# apt-get update  # apt-get upgrade

2、安装Git服务

完成了更新操作后，就可以开始安装Git服务了。

# apt-get install git-core  Reading package lists... Done  Building dependency tree         Reading state information...

3、基本的配置

一旦完成以上安装过程，就该进行Git服务的配置。最基本的配置是这样的：

# git config --global user.name "chszs"  # git config --global user.email chszs@csdn.net

可以根据自己的实际，替换用户名和密码。
