Git使用之Permission Denied问题解决

今天碰到了Git的Permission Denied问题。

在安装好git之后，我们通常会配置username和邮箱

git config --global user.name "zengjinlong" #--global表明本机的全部git仓库均使用该配置

git config --global user.email "zengjinlong@xunlei.com"

可是当我们克隆一个库的时候。发现不论你怎么输入password都是说Permission Denied。

事实上，这是你没有生成公钥

找到这个页面：

SSH Keys





SSH key allows you to establish a secure connection between your computer and GitLab





Before generating an SSH key, check if your system already has one by running cat ~/.ssh/id_rsa.pub If your see a long string starting with ssh-rsa or ssh-dsa, you can skip the ssh-keygen step.





To generate a new SSH key just open your terminal and use code below. The ssh-keygen command prompts you for a location and filename to store the key pair and for a password. When prompted for the location and filename you can press enter to use the default.
It is a best practice to use a password for an SSH key but it is not required and you can skip creating a password by pressing enter. Note that the password you choose here can't be altered or retrieved.





ssh-keygen -t rsa -C "$your_email"

Use the code below to show your public key.





cat ~/.ssh/id_rsa.pub

Copy-paste the key to the 'My SSH Keys' section under the 'SSH' tab in your user profile. Please copy the complete key starting with ssh- and ending with your username and host.

非常easy，就是用你的邮箱生成一个公钥，然后增加到你的代码管理站点中。然后在例如以下页面中增加SSH Key到项目中。

My SSH keys

Add SSH Key

SSH keys allow you to establish a secure connection between your computer and GitLab 

Before you can add an SSH key you need to generate it

然后再git clone 一次，发现能够了。好了。这个问题解决。
