今天在公司上传了代码，回到家pull，结果竟然出现了“Permission denied (publickey)“这种东西。第一反应是key不对，可是上次明明用key登录过，不可能不对啊，难道是文件被删除或覆盖？赶紧ls .ssh瞅一眼，发现上次生成的git、git.pub文件好好的在那呢。再想想，我也没动过github上的key设置啊，在公司都是https方式push的呢。确认不是key的设置问题，在http://henzil.easymorse.com/?p=508找到了解决方案。
下面记录一下解决过程：

PS:ssh-add指令我也不是很熟悉，上面尝试添加public key时的警告请大家再查资料了。有时候.ssh目录下的key太多，可能会导致ssh登录不上，这时需要写ssh配置文件解决。
