# Supervisorctl for Python Programs: A Comprehensive Guide

### **Introduction**

[Supervisorctl](http://supervisord.org/introduction.html) is a command-line utility that <mark>allows you to manage and control Python programs (or any other processes)</mark> using the Supervisor process manager. This guide focuses on using Supervisorctl specifically for [Python](https://bytescrum.com/) programs, which are often <mark>used for web applications, background tasks, or other automation tasks</mark>.

### **Installation**

Before using [Supervisorctl](https://medium.com/naukri-engineering/using-supervisor-to-manage-processes-in-linux-98ae4894e9c7), you need to have Supervisor installed on your system. You can install it using the package manager for your operating system. For example, on Ubuntu, you can use apt:

```bash
sudo apt-get install supervisor
```

### **Configuring Supervisor for Python Programs**

To manage Python programs with [Supervisor](https://www.digitalocean.com/community/tutorials/how-to-install-and-manage-supervisor-on-ubuntu-and-debian-vps), you need to define a program configuration in Supervisor's configuration file (`/etc/supervisor/supervisord.conf` by default). Here's an example of a basic Supervisor configuration for a Python program:

```plaintext
[program:my_python_program]
command=/path/to/python /path/to/your/python/program.py
directory=/path/to/your/python/program/
autostart=true
autorestart=true
stderr_logfile=/var/log/my_python_program.err.log
stdout_logfile=/var/log/my_python_program.out.log
```

In this configuration:

* `program:my_python_program` is the name of the program.
    
* `command` is the command to execute your Python program.
    
* `directory` is the working directory of your Python program.
    
* `autostart` specifies whether the program should start automatically when Supervisor starts.
    
* `autorestart` specifies whether the program should be restarted automatically if it exits.
    
* `stderr_logfile` and `stdout_logfile` specify the log files for standard error and standard output, respectively.
    

### **Managing Python Programs with Supervisorctl**

Once you have configured Supervisor for your Python program, you can use Supervisorctl to manage it:

* To start your Python program:
    

```bash
supervisorctl start my_python_program
```

* To stop your Python program:
    

```bash
supervisorctl stop my_python_program
```

* To restart your Python program:
    

```bash
supervisorctl restart my_python_program
```

* To check the status of your Python program:
    

```bash
supervisorctl status my_python_program
```

* To view the configuration of your Python program:
    

```bash
supervisorctl show my_python_program
```
