linux系统中scp命令实现服务器之间数据的传输

1、从本地服务器传输至另一台服务器

测试服务器连通性：

[root@centos79 test]# ifconfig | head -n 3   ## 查看本机服务器ip
ens32: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.3.83  netmask 255.255.255.0  broadcast 192.168.3.255
        inet6 fe80::ede3:5653:e765:1b1a  prefixlen 64  scopeid 0x20<link>
[root@centos79 test]# ping -c 3 192.168.3.33   ## 测试与远程服务器连通性

rtt min/avg/max/mdev = 2.239/2.895/4.027/0.804 ms

2、将本地文件传输至远程服务器

[root@centos79 test]# ls
outcome.map  outcome.ped
[root@centos79 test]# scp outcome.map root@192.168.3.33:/home/test/
root@192.168.3.33's password:                                ## 这里要输入远程服务器对应用户（这里是root）的密码
outcome.map                                                                                        100% 1315KB   6.5MB/s   00:00

3、将远程服务器文件传输至本地服务器

[root@centos79 test]# ls
outcome.map  outcome.ped
[root@centos79 test]# scp root@192.168.3.33:/home/test/test.txt ./
root@192.168.3.33's password:
test.txt                                                                                           100%   22     3.6KB/s   00:00
[root@centos79 test]# ls
outcome.map  outcome.ped  test.txt
