大神们，ssh登录问题求解啊~

jiwang1980

关于ssh配置登录不需要密码

步骤如下：
ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

然后ssh localhost
结果还是让我输入密码

调试信息：

2，tail -f /var/log/secure
没有输出，所以不是认证文件的权限问题

求思路

chenyx

你看下/var/log/messages日志,看看有没有错误

jiwang1980

蝈蝈，木有任何消息提示

taojie2000

log/secure

顺便看相关目录文件查权限

jiwang1980

不是权限问题，secure没有错误输出，3ks

ajdan4q

不要用local,用ssh serv_ip

jiwang1980

这不是问题的原因，3ks

DiDeCrouse

/etc/ssh/sshd_config文件修改了吗？下面几行注释去掉
RSAAuthentication yes
PubkeyAuthentication yes
AuthorizedKeysFile      .ssh/authorized_keys

重启sshd服务，/etc/init.d/sshd restart

Shell_HAT

本地.ssh 700
远程.ssh 755

试了，一样的错误，3ks
