Answer:

Here's what I do to FORCE UNLOCK FOR some locked tables in MySQL

Enter MySQL

mysql -u your_user -p

Let's see the list of locked tables

mysql> show open tables where in_use>0;

Let's see the list of the current processes, one of them is locking your table(s)

mysql> show processlist;

Let's kill one of these processes

mysql> kill put_process_id_here;
