How to Run a Python Script in Linux VPS

It uses a remote synchronization protocol that transfers only the changes between the files, making it an efficient solution for large data transfers. rsync also picks up where it left off when the connection is interrupted.

You’ll also learn about common errors that could occur while running your Python script in Linux and how to troubleshoot them.

Cause: the Python interpreter is not installed or not in the system’s path.

scp [path to file/folder on your machine][username@IP address]:[path to desired location on VPS]

Create a script with a shebang line, #!/usr/bin/env python3. Make it executable by typing chmod +x [Python script]. Add a cron job crontab -e. Specify the schedule [schedule] /path/to/python3 /path/to/script.py and save. Verify with crontab -1.

Prerequisites

scp -P 67003 C:/Users/username/Desktop/Code/* root@31.220.57.32:files

Running Python scripts interactively allows you to execute Python commands line by line in real time, whereas running scripts from the command line allows you to execute the entire script at once. The command line is usually used to execute massive chunks of code that wouldn’t make sense to run in interactive mode.

To launch Python’s interactive mode on your VPS, type Python or Python3 into the terminal to launch the Python interpreter.

sudo yum install epel-releasersync (remote synchronization) is a method for syncing files and directories between two locations. The first time rsync is used, it transfers the entire content of a file or directory.

How to Execute a Python Script in your Linux VPS Command Line

Cause: script does not have execute permissions.

chmod +x [Python file]
chmod +x executable.py

Troubleshoot: use chmod +x [Python file] to grant execute permissions to your script

When you’re ready, launch the PuTTY SSH client by typing putty into your Linux terminal. Use Ctrl + Alt + T or Command + Option + T if you’re using macOS to open the Terminal.

Refer to the rsync manual for comprehensive documentation and additional options:

To run your script, you’ll need to import it from your local machine, and there are several ways to do this. Each method offers a different approach to transferring data from your machine to your VPS, with varying levels of complexity and security.

bash: python3: command not found

Python’s integration with Linux-based systems is seamless, thanks to the availability of interpreters and libraries in Linux repositories. In this tutorial, we’ll explain how to run a Python script in your remote server’s Linux command line.

First, connect to your VPS using PuTTY. You’ll need to download it to your system to access your server.

Error message: PermissionError: [Errno 13] Permission denied

2. Executing Python Commands Interactively

which python3

Error message: no such file or directory: ‘script.py’

5. View Logs

tail /var/log/syslog or

Ubuntu/Debian

2. Make Sure Python Is Installed on Your VPS

These steps will help you smoothly execute Python code for numerous tasks, from automation to system management. We hope you’ve found this article helpful!

First, update the package index using the following:

Moving on, another command that helps you view the log files is the tail command. However, it only shows the last part of the file, where problems usually lie:

python3 script.py or python2 script.py

Interpreter Not Found Error

Linux is a powerful tool that makes running Python a piece of cake. This is beneficial because Python is a high-level programming language used to create powerful applications and systems.

Next, navigate to the folder containing the file:

sudo systemctl start rsync Enter your server’s SSH IP and SSH Port. Click Open to proceed.

4. Run the Script and View it in the Terminal

For Ubuntu, Linux Mint, and Debian use the following:

cd path/to/file

Troubleshoot: specify the desired Python version explicitly when running the script, depending on your requirements:

In interactive mode, there is little room for error. You’d have to repeat the entire code if you make a mistake. This is why interactive mode is mainly used to test code snippets and not for creating large chunks of code.

Troubleshooting Common Execution Errors

Troubleshoot: make sure you are in the correct directory or provide the full path to the script:

rsync

If everything is working correctly, you should see a progress bar that will alert you when the process is complete.

Before we begin, have the following details of your VPS ready:

sudo dnf install python3 python3-devel python3-pip

First things first, ensure your VPS has Python installed. Most Linux distributions come with Python preinstalled, but you’ll have to install it manually if you don’t own a VPS. To check whether or not you have Python installed, run this command:

These permissions are represented by a series of letters or numbers, known as the file mode or permission mode. The chmod command above adds execute permissions to your script.

sudo dnf install rsync

Cause: script file path is incorrect.

To run a Python executable in Linux, simply navigate to the executable’s directory and run it using the ./ prefix followed by the filename. After running the script, you’ll see the output in the terminal, or if it’s an application, a window will open.

First, connect to the server using the following command:

VPS → Server Details → Manage. Your credentials are located under the SSH access tab.
