Bug: MISP cannot access workers

[clunk0y]

Actual behavior

Expected behavior

Hello,

After updating to version 2.5, MISP is unable to access Redis and displays the following error:

Warning: MISP cannot access your /proc directory to check the status of the worker processes, which means that dead workers will not be detected by the diagnostic tool. If you would like to regain this functionality, make sure that the open_basedir directive is not set, or that /proc is included in it.

Warning: MISP cannot connect to the Supervisord API, check the following settings are correct: [`supervisor_host`, `supervisor_port`, `supervisor_user`, `supervisor_password`] and restart the service. For details check the MISP error logs.

. Interestingly, Redis is running on port 6379, and I am receiving a pong response, but MISP cannot connect to it. Additionally, the supervisor username and password have been entered correctly. I would appreciate your assistance with this issue.

Thank you!

Feel free to add the specific error message where indicated!

Hey there, the issue appears to be that MISP cannot connect to supervisord. Some troubleshooting steps:

1. Check the config variables for SimpleBackgroundJobs and ensure that the redis and supervisor variables are set correctly.
2. Ensure that redis and supervisord are configured accordingly to your variables, especially username and password.
3. Check redis and supervisord logs for errors.

Hello there, All these tasks have been completed, and there are no issues in the logs. I even manually tested the status of Redis and Supervisor using curl, and they are working. There was nothing in the announced logs. The only log with an error is the MISP error log.

Looks like the redis extension for PHP is missing, this may be caused by multiple things. Do you see redis when running "php -m"? If not, try running "phpenmod redis"

Yes, I can see Redis in "php -m".

Do you have both php7.4 and php8.x installed now? Which php binary is php -m using? I assume that it might be using 7.4 still?

@clunk0y How you fixed it? I have same problem and diagnostics page shows internal error message.

Check if the PHP version running on MISP is truly 8.3 by

<?php
phpinfo();
?>
