这个问题如果理解不深入的话很容易答错，正确答案应该为：将A机器的id_rsa.pub(公钥)输出到B机器的authorized_keys中。[root@hadoop000 ~]# rm -rf ~/.ssh
[root@hadoop000 ~]# ssh-keygen
[root@hadoop000 ~]# cd .ssh
[root@hadoop000 .ssh]# cat id_rsa.pub >> authorized_keys
[root@hadoop001 ~]# rm -rf ~/.ssh
[root@hadoop001 ~]# ssh-keygen
[root@hadoop001 ~]# cd .ssh
[root@hadoop001 .ssh]# cat id_rsa.pub >> authorized_keys
生成公钥 并将公钥放入本机authorized_keys中[root@hadoop000 .ssh]# scp id_rsa.pub 192.168.137.251:/root/.ssh/id_rsa.pub.hadoop000
[root@hadoop001 .ssh]# cat id_rsa.pub.hadoop000 >> authorized_keys不互信情况下 A机器scp一个文件到B机器 无需密码操作方法
