centos 7 安装git并配置ssh

一、安装

1、查看是否安装git

<span style="color:#333333"><span style="background-color:#ffffff"><code class="language-perl">rpm -qa|<span style="color:#0000ff">grep</span> git
</code></span></span>

有git加版本号就说明已经安装过了

2、安装git

<span style="color:#333333"><span style="background-color:#ffffff"><code class="language-mipsasm">yum <span style="color:#0000ff">install </span>git
</code></span></span>

3、查看git版本

<span style="color:#333333"><span style="background-color:#ffffff"><code class="language-undefined">git version
</code></span></span>

二、配置git账户

1、配置帐户和密码

<span style="color:#333333"><span style="background-color:#ffffff"><code class="language-verilog">git <span style="color:#0000ff">config</span> --<span style="color:#0000ff">global</span> user<span style="color:#008000">.name</span> <span style="color:#a31515">"Your Name"</span>
git <span style="color:#0000ff">config</span> --<span style="color:#0000ff">global</span> user<span style="color:#008000">.email</span> <span style="color:#a31515">"email@example.com"</span>

</code></span></span>

2、查看配置是否生效

<span style="color:#333333"><span style="background-color:#ffffff"><code class="language-lua">git <span style="color:#0000ff">config</span> <span style="color:#008000">--list</span>
</code></span></span>

三、配置SSH用于拉取远程仓库

1、先在本地生成ssh key，生成公钥和私钥，后续在github等代码托管配置中需要用到

<span style="color:#333333"><span style="background-color:#ffffff"><code class="language-perl">ssh-keygen -t rsa -C <span style="color:#a31515">"your_email@youremail.com"</span>
</code></span></span>

2、确认路径按1次回车，提示：Enter passphrase（输入密码），不用输密码再按2次回车即可。生成的密钥存放路径 /root/.ssh/id_rsa

3、id_rsa：私钥，id_rsa.pub：公钥

<span style="color:#333333"><span style="background-color:#ffffff"><code class="language-bash"><span style="color:#0000ff">cat</span> /root/.ssh/id_rsa.pub
</code></span></span>

四、配置github

1、打开 GitHub: Let’s build from here · GitHub

2、New SSH key 添加一个新的ssh key

3、复制刚才生成的 id_rsa.pub 公钥，Add SSH key

其他代码托管如gitlab等类似

五、测试拉github私有项目

1、git clone拉取远程代码，配置了SSH 公/私有项目都是可以拉的，拉取的路径在当前路径

<span style="color:#333333"><span style="background-color:#ffffff"><code class="language-bash">git <span style="color:#0000ff">clone</span> git@github.com:yourname/xxx.git
</code></span></span>
