(解决了,需禁用selinux)
CentOS 6 64bit
同样的配置方法,普通的用户可以,root用户不行
sshd_config中修改了
PasswordAuthentication no
AuthorizedKeysFile .ssh/authorized_keys
PermitRootLogin without-password
自己ssh自己都不行,外面也不行
ssh CentOS-hdp2
Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
日志如下:

# This sshd was compiled with PATH=/usr/local/bin:/bin:/usr/bin

# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options change a
# default value.
