1.       安装步骤

1>  首先应该安装好必要的依赖包，省得在安装过程中出现各种问题。

# yum install curl-devel expat-develgettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker

2>  下载并编译git 

# wget https://www.kernel.org/pub/software/scm/git/git-1.8.3.1.tar.gz

# tar xzf git-1.8.3.1.tar.gz

3>  编译并验证

# cdgit-1.8.3.1

# makeprefix=/usr/local/git all

# makeprefix=/usr/local/git install

# echo"export PATH=$PATH:/usr/local/git/bin" >>/etc/bashrc

# source/etc/bashrc

# git--version

4>  生成密钥

#cd/root/.ssh

#ssh-keygen-t rsa

Generatingpublic/private rsa key pair.

Enterfile in which to save the key (/root/.ssh/id_rsa): （直接回车）

Enterpassphrase (empty for no passphrase): （直接回车）

Entersame passphrase again: （直接回车）

Youridentification has been saved in /root/.ssh/id_rsa.

Yourpublic key has been saved in /root/.ssh/id_rsa.pub.

The keyfingerprint is:

在root/.ssh目录下生成密钥对 id_rsa和id_rsa.pub，其中id_rsa是私钥，id_rsa.pub是公钥。

5>  登录github帐号，添加公钥

https://github.com  登录个人帐号，进入setting/keys,   点击   SSH and GPG keys   添加密钥 即可。
