服务端
# ls
Discuz_X3.1_SC_UTF8.zip
在客户端根目录下pwd
# pwd
/root
回到服务端
# scp -r Discuz_X3.1_SC_UTF8.zip root@192.168.100.110:/root/
The authenticity of host ‘192.168.100.110 (192.168.100.110)‘ can‘t be established.
ECDSA key fingerprint is bd:e6:37:d2:73:28:f7:08:93:48:f4:40:61:81:a5:d1.
Are you sure you want to continue connecting (yes/no)? yes

根目录下创建stor文件
#mkdir stor
将dvd中内容复制于stor中
#cp dvd.repo stor/
# scp -d stor root@192.168.100.110:/root
root@192.168.100.110‘s password:
stor: not a regular file
# yum list | grep rsync
# yum list installed | grep rsync
rsync.x86_64 3.0.9-15.el7 @anaconda/7.0
# systemctl start rsyncd
# netstat -anutp | grep 873

第一种密码传输
在根目录下随意创建一个文件并进行编辑
# mkdir zxt.txt
#vi /root/zxt.txt
向客户端传输zxt文件，
# scp -r /root/zxt.txt root@192.168.100.110:/root/
root@192.168.100.110‘s password:
zxt.txt 100% 4 0.0KB/s 00:00
在客户端ls查询
# ls
第二种不需要密码来传输，
服务端客户端生成一个密钥
# ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Created directory ‘/root/.ssh‘.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
