Permission denied (publickey)的解决办法

在添加完Coding.net的ssh-key以后，执行ssh -T git@git.coding.net时，会出现如下错误：

Warning: Permanently added the RSA host key for IP address '106.75.4.187' to the list of known hosts.
git@git.coding.net: Permission denied (publickey).

这个错误在之前添加gitee时也遇到过，当时忘记怎么处理了，翻了下history，发现执行如下命令即可解决：

ssh-add ~/.ssh/id_rsa.coding

id_rsa.coding是你生成ssh-key时指定的名称，例如本文生成ssh-key的命令为：

ssh-keygen -t rsa -f ~/.ssh/id_rsa.coding -C "Coding"

接着在~/.ssh/config中加入如下配置：

Host coding.net
    IdentityFile ~/.ssh/id_rsa.coding
    User xxx (此处填写coding的用户名)

此时再执行ssh -T git@git.coding.net命令就可以通过了

ssh -T git@git.coding.net
Warning: Permanently added the RSA host key for IP address '123.59.85.99' to the list of known hosts.
Coding 提示: Hello oka, You've connected to Coding.net via SSH. This is a personal key.
xxx，你好，你已经通过 SSH 协议认证 Coding.net 服务，这是一个个人公钥
