【linux】ssh连接问题

在服务器已经配置了authorized_keys，但是还是要输入密码。

打印ssh -vvT

我在.ssh目录下有

[email protected]:~/.ssh$ ls
id_rsa  id_rsa.pub  known_hosts

却不能校验

网络上大部分教程不完整导致。。。因我是git用户要给.ssh 755权限。才可使用。但大多教程700导致。

这个提示不影响登录的，你如果需要ssh登录服务器那么需要把你的id_rsa.pub即公钥内容配置到服务器对应用户名下的.ssh目录中的authorized_keys文件中。

如果配置了不能登录：

  1. 检查用户名是否正确；

  2. 服务器配置/etc/ssh/sshd_config是否允许通过key登录；

  3. 确认authorized_keys配置的你的公钥是否正确，一条key记录不允许出现换行。

这是我本地的日志，不影响登录的啊，你ssh登录的时候需要用命令:

ssh [email protected]

你的登录用户名设置正确吗？
都检查下吧！
