我有一个CentOS 6.3服务器和一个名为ako的用户。
我运行Kubuntu 12.10作为我的客户端，并使用ssh-copy-id命令将我的公钥复制到服务器。
我用这些值更新了/etc/ssh/sshd_config文件：
RSAAuthentication yes PubkeyAuthentication yes StrictModes yes PasswordAuthentication no
但是，当我尝试login到服务器，我得到这个错误：
Permission denied (publickey).
我已经安装了很多次SSH，没有问题，但我不知道为什么这个不工作！

这是以详细模式运行的ssh的输出：

你可以在详细模式下运行你的ssh来查看具体信息……看起来你是以不同的用户身份连接的……“ako”
检查目标系统上“ako”用户主目录的权限。 ssh-copy-id应该已经为你做了。
chmod go-w ~/ chmod 700 ~/.ssh chmod 600 ~/.ssh/authorized_keys
您已将您的ID文件从具有AppArmor的系统复制到使用SELinux的系统。
在Centos 6.3机器上运行：
restorecon ~/.ssh/authorized_keys chcon unconfined_u:object_r:ssh_home_t:s0 ~/.ssh/authorized_keys 上下文应该看起来像。
ls -Z .ssh / authorized_keys
-rw ——-。 用户用户unconfined_u：object_r：ssh_home_t：s0 .ssh / authorized_keys
