    This looks fairly normal. The log file shows that MySQL was not previously shutdown properly, but went into recovery and appears to be recovered fine.

    You said MySQL isn't running, what happens when you try to access MySQL, do you get any errors?

    Yes, it's normal for the MySQL server to constantly run. Otherwise, your databases would not be accessible.

    Thank you.
