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 localhostcd ~/.ssh/                     # 若没有该目录，请先执行一次ssh localhostssh-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 localhostssh localhost                  # 测试是否配置成功

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

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