Hello @amergingtech,

I can see this error in your /opt/bitnami/mysql/data/mysqld.log:

2020-09-07T14:53:02.960747Z 0 [ERROR] Unix socket lock file is empty /opt/bitnami/mysql/tmp/mysql.sock.lock.
2020-09-07T14:53:02.960752Z 0 [ERROR] Unable to setup unix socket lock file.
2020-09-07T14:53:02.960756Z 0 [ERROR] Aborting

Can you try to remove that file and restart the MySQL’s service?

sudo rm -rf /opt/bitnami/mysql/tmp/mysql.sock.lock
sudo /opt/bitnami/ctlscript.sh restart mysql

I hope it helps
