1. 进入ssh文件下

cd ~/.ssh

2. 生成ssh key

ssh-keygen -t rsa -C 你的油箱

3. 提示输入目录，目录可以不填，有默认路径，直接回车

# ‘()’里面是默认路径Enter file in which to save the key (/Users/user/.ssh/id_rsa):

4. 提示输入密码, 密码可以不填, 默认没有密码，直接回车

5. 提示再次输入密码, 直接回车,

Enter passphrase (empty for no passphrase):Enter same passphrase again:

6. 当出现以下图案, 则表示生成 成功

Your identification has been saved in /Users/user/.ssh/id_rsa.Your public key has been saved in /Users/user/.ssh/id_rsa.pub.The key fingerprint is:SHA256:IQP0sSMslL9VG+HXO9oqlnFNTkeI1/m9fBiBoKIcdxk  [nanananamln@163.com](mailto:nanananamln@163.com)  The key’s randomart image is:+—[RSA 2048]——+|  .oo .

7. 打开*.pub复制生成的ssh key 粘贴到Git上

# 路径是上面的默认路径 sudo vi /Users/malina/.ssh/id_rsa.pub

扩展：生成多个ssh key

1.当要生成多个ssh key时(比如github，gitlab等)，则需要在第3步里添加目录以便区分

Enter file in which to save the key (/Users/user/.ssh/id_rsa):github_rsaEnter file in which to save the key (/Users/user/.ssh/id_rsa):gitlub_rsa# 因为已经在.ssh文件夹里面，所以前面路径不用写

2.添加私钥

# 一般私钥会自动添加 # 查看私钥 ssh-add -l# 删除私钥 ssh-add -D# 添加私钥 ssh-add github_rsassh-add gitlub_rsa# 因为已经在.ssh文件夹里面，所以前面路径不用写，否则要写成ssh-add ~/.ssh/gitlub_rsa

3.配置config文件

# ssh文件里面没有config直接创建即可# 创建/更改 vim config# 内容为： # githubHost  [github.com](http:#github.com/)      HostName  [github.com](http:#github.com/)      PreferredAuthentications publickey    IdentityFile ~/.ssh/github_rsa# gitlabHost  [gitlab.readtv.cn](http:#gitlab.readtv.cn/)      HostName  [gitlab.readtv.cn](http:#gitlab.readtv.cn/)      PreferredAuthentications publickey    IdentityFile ~/.ssh/gitlab_rsa

若第四步设置了密码，

1.命令行执行：

ssh-keygen -p

2.提示如下，不用管直接回车

Enter file in which the key is(/c/Users/YourUserName/.ssh/id_rsa):

3.输入老密码和新密码，输入新密码时直接回车即可
