implementing cron job executing Python script scenarios silently on RHEL 8
I've been struggling with this for a few days now and could really use some help. I've been trying to set up a cron job on my RHEL 8 system to run a Python script every day at midnight, but it appears that the script is failing silently and no output is generated. The cron job is configured as follows: ```bash 0 0 * * * /usr/bin/python3 /path/to/my_script.py >> /var/log/my_script.log 2>&1 ``` I've checked the path to Python and confirmed that the script works flawlessly when executed manually from the terminal. Additionally, I've made sure that the script has executable permissions using `chmod +x /path/to/my_script.py`. However, when I check the log file (`/var/log/my_script.log`), it remains empty after the scheduled time. I also tried adding some debug prints to the script itself, like `print('Script started')`, to see if it’s even being invoked at all, but they don’t appear in the log either. The cron service is running, as I verified with `systemctl status crond`. Furthermore, I checked the cron logs at `/var/log/cron` and saw the entry: ``` Oct 10 00:00:01 myhost crond[1234]: (myuser) CMD (/usr/bin/python3 /path/to/my_script.py >> /var/log/my_script.log 2>&1) ``` This indicates that the cron job is indeed being triggered. I suspect it might be an environment scenario since the script relies on certain environment variables defined in my shell. I tried executing the script as a different user, and that seemed to work, but I need it to run as my main user. Any ideas on how to troubleshoot this scenario or ensure that the environment is set correctly for the cron job? I'd really appreciate any guidance on this.
