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。
操作步骤：（假设hadoop000为A hadoop001为B）
1.两台机器执行
[[email protected] ~]# rm -rf ~/.ssh
[[email protected] ~]# ssh-keygen
[[email protected] ~]# cd .ssh
[[email protected] .ssh]# cat id_rsa.pub >> authorized_keys
[[email protected] ~]# rm -rf ~/.ssh
[[email protected] ~]# ssh-keygen
[[email protected] ~]# cd .ssh
[[email protected] .ssh]# cat id_rsa.pub >> authorized_keys
生成公钥 并将公钥放入本机authorized_keys中2.A机器的id_rsa.pub拷贝到B机器并输出到authorized_keys中
[[email protected] .ssh]# scp id_rsa.pub 192.168.137.251:/root/.ssh/id_rsa.pub.hadoop000
[[email protected] .ssh]# cat id_rsa.pub.hadoop000 >> authorized_keys原文地址：http://blog.51cto.com/10814168/2115734
