How can I change mysql port from 0 to 3306?

Question

I find it hard to establish a link between jdbc and mysql. I think one of the reasons is the mysql port. I checked the port with the statement: \"show variables like \'port\';\"

Answer 1

I had this problem because I had forgotten that I started mysqld with the --skip-networking flag in order to reset the MySQL root password, like so:

sudo /usr/sbin/mysqld --skip-grant-tables --skip-networking &

Run ps aux | grep mysql and you may see the process (or a pair of them) hanging around still. If so, kill it/them and then restart mysql.
