ssh key 一模一样的设置，另一个就不能 登录是什么原因？
資深大佬 : selfcreditgiving 24
要用 user1 用户 ssh 登录两台服务器。
两个服务器，拷贝了相同的公钥：
/home/user1/.ssh/id_rsa.pub
和 /home/user1/.ssh/authorized_keys （ id_rsa.pub 拷进来的）
两个文件的权限都是 700
/home/user1 文件夹的权限是 600
id_rsa.pub 、authorized_keys 、/home/user1 的所属用户和所属组都是 user1
/etc/ssh/sshd_config 设置的也是一模一样的， 也重新启动了 sshd service 。
为什么一台可以登录，一台就登录不了呢？
提示这个错误：
Permission denied (publickey). 每次都被这种东西卡住了，
/etc/ssh/sshd_config 配置都是这样的：

UsePAM no 大佬有話說 (27)
