Imunify agent is not started due to the initialized module 'MySQLdb'

Issue

• The Imunify agent is not started:

# service imunify-antivirus status
Redirecting to /bin/systemctl status imunify-antivirus.service
● imunify-antivirus.service - ImunifyAV
Loaded: loaded (/usr/lib/systemd/system/imunify-antivirus.service; enabled; vendor preset: disabled)
Active: failed (Result: exit-code) since Sun 2022-02-05 13:22:22 CEST; 31s ago

• running any Imunify agent command and /var/log/imunify360/error.log contains the following errors:

File "/opt/alt/python38/lib64/python3.8/site-packages/MySQLdb/__init__.py", line 18, in <module>
from . import _mysql
ImportError: cannot import name '_mysql' from partially initialized module 'MySQLdb' (most likely due to a circular import) (/opt/alt/python38/lib64/python3.8/site-packages/MySQLdb/__init__.py)

Environment

Any environment supported by ImunifyAV and Imunify360.

Solution

1. Check if you are getting an error using:

# file /opt/alt/python38/lib64/python3.8/site-packages/_mysql.so

2.  The installed module is incompatible with Imunify. If its removal is possible, you can try the following:

# /opt/alt/python38/bin/python3 -m pip uninstall mysql

# /opt/alt/python38/bin/python3 -m pip uninstall mysqlclient

# service imunify-antivirus start

or

# service imunify360 start

Cause

The Imunify agent is not started due to MySQLdb package incompatibility.
