[ Python 常見問題 ] How do I copy a file to a remote server in python using scp or ssh?

Question:
As title.

Solution:
方法一:
If you want the simple approach, this should work. You'll want to ".close()" the file first so you know it's flushed to disk from Python. Also you will need to generate (on the source machine) and install (on the destination machine) an ssh key beforehand so that the scp automatically gets authenticated with your public ssh key (in other words, so your script doesn't ask for a password). Below is the sample code to comply with your request:

view plaincopy to clipboardprint?

1. import os  
2. os.system("scp FILE USER@SERVER:PATH")  
3. #e.g. os.system("scp foo.bar joe@srvr.net:/path/to/foo.bar")

* Python module - os: os.system(command)

Execute the command (a string) in a subshell. This is implemented by calling the Standard C function system(), and has the same limitations.

方法二:
To do this in Python (i.e. not wrapping scp through subprocess.Popen or similar) with the Paramiko library, you would do something like this:

view plaincopy to clipboardprint?

1. import os  
2. import paramiko  
3.   
4. ssh = paramiko.SSHClient()   
5. ssh.load_host_keys(os.path.expanduser(os.path.join("~", ".ssh", "known_hosts")))  
6. ssh.connect(server, username=username, password=password)  
7. sftp = ssh.open_sftp()  
8. sftp.put(localpath, remotepath)  
9. sftp.close()  
10. ssh.close()  

If you want to execute command in remote server, below is the sample code:

view plaincopy to clipboardprint?

1. ssh = paramiko.SSHClient()  
2. ssh.connect(server, username=username, password=password)  
3. ssh_stdin, ssh_stdout, ssh_stderr = ssh.exec_command(cmd_to_execute)
