+# git配置ssh
+
+**确认已经存在的ssh key** 
+
+windows在gitbash中执行
+
+```sh
+ls -al ~/.ssh
+```
+
+**如果没有，生成新的ssh key 并添加到ssh-agent**
+
+生成ssh-key
+
+```sh
+ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
+#Enter a file in which to save the key (/Users/you/.ssh/id_rsa): [Press enter]   回车存放在默认地址
+
+#Enter passphrase (empty for no passphrase): [Type a passphrase]
+#Enter same passphrase again: [Type passphrase again]
+#为ssh-key设置密码 在添加到ssh-agent时需要输入
+```
+
+私钥添加到ssh-agent
+
+1.保证ssh-agent启用 返回经称id
+
+```sh
+eval "$(ssh-agent -s)" 
+```
+
+2.把ssh key添加到ssh-agent中
+
+```sh
+ssh-add ~/.ssh/id_rsa  #  ~/.ssh/id_rsa 为默认存放地址
+```
+
+**在github中添加ssh key公钥**
+
+```sh
+~/.ssh/id_rsa.pub # 公钥地址
+C:\Users\58443\.ssh # windows中对应路径
+```
+
+settings->ssh and gpg keys -> new ssh key
+
+**测试连接**
+
+```sh
+ssh -T git@github.com
+#The authenticity of host 'github.com (20.205.243.166)' can't be established.
+#RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8.
+#Are you sure you want to continue connecting (yes/no/[fingerprint])? 
+# yes
+#Warning: Permanently added 'github.com,20.205.243.166' (RSA) to the list of known hosts.
+#Hi privking! You've successfully authenticated, but GitHub does not provide shell access.

+**更改远程仓库url为ssh**
+
+查看拥有的远程仓库：
+
+```ssh
+git remote -v
+```
+
+更改远程仓库的url：
+
+```ssh
+git remote set-url origin  git@github.com:privking/king-note.git
+```
+
+查看是否修改成功
+
+```ssh
+git remote -v
+```
