今天碰到了Git的Permission Denied问题。

在安装好git之后，我们一般会配置用户名和邮箱

git config --global user.name "zengjinlong"

#--global表明本机的所有git仓库均使用该配置

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

但是当我们克隆一个库的时候，发现不论你怎么输入密码都是说Permission Denied。

其实，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.

很简单，就是用你的邮箱生成一个公钥，然后加入到你的代码管理网站中。然后在如下页面中加入SSH Key到项目中。

My SSH keys

SSH keys allow you to establish a secure connection between your

computer and GitLab

Before you can add an SSH key you need togenerate it

然后再git clone 一次，发现可以了。好了。这个问题解决。
