Scp is a file copy with security, which is logged in based on ssh. It is easy to operate, for example, to copy a current file to another remote host, you can use the following command.

The copy code is as follows:

Scp / home/daisy/full.tar.gz

Then you will be prompted to enter the login password of the root user on the other 172.19.2.75 host, and then you will start copy.

It is also easy to copy files from the remote host to the current system if you want to do the reverse.

The copy code is as follows:

Scp root@172.19.2.75:/home/root / home/daisy/full.tar.gz

This paper gives an example to explain the implementation process of file transfer between linux servers for your reference. The details are as follows.

1.1 transfer files normally, do not need to connect to server b through the proxy service, log in to server a, and execute

Scp test.sql user@server-b:path

Note: transfer the file test.sql to server b (user is the user name of server b, server-b is the ip,path of server b, specify the path to receive files on server b), enter the password of user

1.2 you need to access server b through a proxy and execute

Scp-oproxycommand='nc-v-xproxy:port h p 'test.sql user@server-b:path

Note: ip,port whose proxy is the proxy server is the port of the proxy server. Enter the password of user by entering enter.

Alternatively, you can use the sftp command, which is basically the same format as above:

Sftp-oproxycommand='nc-v-xproxy:port h p 'user@server-b port

Description: the latter port is the port of server b

1.3 transfer files using scp

1) download files from the server

Scp username@servername:/path/filename / tmp/local_destination

For example, scp codinglog@192.168.0.101:/home/kimi/test.txt downloads the file / home/kimi/test.txt on 192.168.0.101 to / tmp/local_destination

2) upload local files to the server

Scp / path/local_filename username@servername:/path

For example, scp / var/www/test.php codinglog@192.168.0.101:/var/www/ transfers the test.php file in the local / var/www/ directory

Upload to the / var/www/ directory on the server 192.168.0.101

3) download the entire directory from the server

Scp-r username@servername:remote_dir/ / tmp/local_dir

For example: scp-r codinglog@192.168.0.101 / home/kimi/test / tmp/local_dir

4) upload the directory to the server

Scp-r / tmp/local_dir username@servername:remote_dir

For example:

Scp-r test codinglog@192.168.0.101:/var/www/ uploads the test directory under the current directory to the server's / var/www/ directory
