Supervisor (AutoPy)

▲ ▼

description Supervisor (AutoPy) Overview

Supervisor is a battle-tested process control system perfect for keeping background services and scripts running reliably on Linux servers. It monitors specified processes and automatically restarts them if they exit unexpectedly, making it a staple for small to medium-sized deployments. Its configuration is straightforward, allowing users to define restart policies (e.g., always, on-failure) with minimal overhead.

help Supervisor (AutoPy) FAQ

How do I configure Supervisor to automatically restart a Python script if it crashes?

You need to add a program section to your supervisord.conf file and set the 'autorestart' parameter to 'true'. Supervisor will then monitor the process and automatically restart it if it exits unexpectedly, utilizing the configured 'startsecs' and 'startretries' values.

Does Supervisor require root privileges to run on a Linux server?

While it can run as root to manage services across different user accounts, it does not strictly require root privileges. You can configure a non-root user to run Supervisor and manage their own processes by adjusting the file permissions for the unix socket.

How can I check the status of processes managed by Supervisor via the command line?

You can run the command 'supervisorctl status' in your terminal to see a list of all managed processes and their current states. If you need to restart a specific service manually, simply type 'supervisorctl restart [process_name]'.

What is the difference between using Supervisor and systemd for process management?

Systemd is a full Linux init system that boots up with the OS, whereas Supervisor is a dedicated process manager that requires being started by an init system. Many developers prefer Supervisor for Python deployments because it handles program restarts and log management across Unix-like systems without needing complex service files.
