两台虚拟机之间拷贝东西

本机(hadoop1)文件拷贝到其他主机

操作命令   scp -r module root@hadoop2:/opt/module

　　-r递归

　　module本地目录

　　root操作的用户

　　hadoop2主机名

　　/opt/module拷贝到虚拟机的目录

[root@hadoop1 opt]#   scp -r module root@hadoop2:/opt/module

Are you sure you want to continue connecting (yes/no)? yes 输入yes确定

[root@hadoop1 opt]#

 

 

把其他主机文件拷贝到本主机(hadoop2)

操作命令 scp -r root@hadoop1:/opt/module ./module/　

　　-r递归

　　root@hadoop1:/opt/module  其他主机(hadoop1)的目录

　　./module/　

[root@hadoop2 opt]# scp -r root@hadoop1:/opt/module ./module/

主机hadoop1 把hadoop2上的东西拷贝到 hadoop3上

scp -r root@hadoop1:/opt/module  root@hadoop2:/opt/module

 

也可以使用 rsync
