ssh 仍然需要密码

在配完ssh后居然还需要输入密码，我怀疑我配了个假的ssh

配置过程： 来自博客给力星点击查看

ssh localhost
cd ~/.ssh/                     # 若没有该目录，请先执行一次ssh localhost
ssh-keygen -t rsa              # 会有提示，都按回车就可以
cat ./id_rsa.pub >> ./authorized_keys  # 加入授权
exit                           # 退出刚才的 ssh localhost
ssh localhost                  # 测试是否配置成功

用root用户登陆查看系统的日志文件：$tail /var/log/secure -n 20

提示/home/hadooper/.ssh和 /home/hadooper/.ssh/authorized_keys权限不对，修改如下：

chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys
