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 [email protected]:/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
Warning: Permanently added ‘192.168.100.110‘ (ECDSA) to the list of known hosts.
[email protected]‘s password:
Discuz_X3.1_SC_UTF8.zip 100% 10MB 10.0MB/s 00:00
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 [email protected]:/root
[email protected]‘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
tcp 0 0 0.0.0.0:873 0.0.0.0:* LISTEN 7223/rsync
tcp6 0 0 :::873 :::* LISTEN 7223/rsync
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 [email protected]:/root/
[email protected]‘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:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
50:07:f2:61:81:e4:8a:58:3c:38:90:9d:e0:a6:b4:18 [email protected]
The key‘s randomart image is:

在服务端
[[email protected] ~]# vi /root/.ssh/authorized_keys
将/root/.ssh/id_rsa.pub中内容写入
保存退出
再次发送发现无需密码
