查看安全相关的日志

sudo cat /var/log/secure

发现是免密文件的权限问题引起的，权限的文件是有一定的规定的不是越高越好，这个也算是linux的自我保护机制吧

chmod 600 /home/bigdata/.ssh/authorized_keys
chown bigdata:bigdata /home/bigdata/.ssh/authorized_keys
ls -l /home/bigdata/.ssh/authorized_keys
chmod 700 /home/bigdata/.ssh
chown bigdata:bigdata /home/bigdata/.ssh
ls -ld /home/bigdata/.ssh
chmod 755 /home/bigdata
chown bigdata:bigdata /home/bigdata
ls -ld /home/bigdata
chmod 600 /home/bigdata/.ssh/id_rsa
ls -l /home/bigdata/.ssh/id_rsa
