在centOs系统下安装个配置git

 在安装git之前要安装它的一些依赖：

1：  sudo yum -y install zlib-devel openssl-devel cpio expat-devel gettext-devel curl-devel perl-ExtUtils-CBuilder perl-ExtUtils- MakeMaker

2：下载git点击打开链接

3：解压 

     tar -xzvf   git-2.8.0.tar.gz

4:进入解压出来的文件git-2.8.0目录，执行make命令

sudo make prefix=/usr/local/git all 完成编译

5：安装git

 sudo make prefix=/usr/local/git  install进行安装

6:这时候执行git --version会提示没有该命令，原因是在linux的path下没有添加git的bin文件，来到/etc/profile进行添加

 在$PATH后添加 /usr/local/git/bin

7:使配置生效 ：

  source /etc/profile

8:配置git 

 [li@iZ2ze0bu41x062fa5a775jZ etc]$ git config --global user.name "你的git用户名"

[li@iZ2ze0bu41x062fa5a775jZ etc]$ git config --global user.email "你的git用户邮箱"

[li@iZ2ze0bu41x062fa5a775jZ etc]$ git config --global core.autocrlf false  //设置因为系统不同所带来的换行符问题

[li@iZ2ze0bu41x062fa5a775jZ etc]$ git config --global core.quotepath off

[li@iZ2ze0bu41x062fa5a775jZ etc]$ git config --global gui.encoding utf-8  //避免中文乱码

生成git公钥

ssh-keygen命令用于为“ssh”生成、管理和转换认证密钥，它支持RSA和DSA两种认证密钥。

[li@iZ2ze0bu41x062fa5a775jZ etc]$ ssh-keygen -t rsa -C "你个git用户邮箱"

Generating public/private rsa key pair.

Enter file in which to save the key (/usr/li/.ssh/id_rsa):回车

Created directory '/usr/li/.ssh'.

Enter passphrase (empty for no passphrase):回车

Enter same passphrase again:

Your identification has been saved in /usr/li/.ssh/id_rsa.

Your public key has been saved in /usr/li/.ssh/id_rsa.pub.

The key fingerprint is:

b8:e9:e8:98:55:89:2d:b1:53:2a:3e:54:00:8f:0c:0f ****@qq.com

The key's randomart image is:

+--[ RSA 2048]----+

|E..              |

|o= .             |

|..o o .          |

|   . B o         |

|  o * = S        |

| o . + o         |

|  o . o          |

|  o.o .          |

ssh-add ssh-add命令网络安全 ssh-add命令是把专用密钥添加到ssh-agent的高速缓存中。

 ssh-add ~/.ssh/id_rsa

Could not open a connection to your authentication agent.

至此，git安装与配置完成

 git 的一些目录规则

~ : 代表“目前用户身份”所在的主文件夹

~account : 代表账户用户的主文件夹
