MySQL: Allow both remote AND local connections

In my Ubuntu's /etc/mysql/my.conf, I have:

bind-address = 192.168.2.20  # My external IP

It works fine from remote, but when I want to connect locally, the app that uses on MySQL says: java.net.ConnectException: Connection refused at com.mysql.jdbc.StandardSocketFactory.connect.

So when I want to work locally, I change my.cnf to:

bind-address = 0.0.0.0

And it starts working locally, but then it doesn't work from remote anymore.

How to make MySQL accesible both from remote AND local?

Solution 1:

Just comment out bind-address= altogether. When you do that, it will bind to all addresses. Also make sure that you don't have skip-networking enabled in your my.cnf.

Solution 2:

I've JUST got it to work using the command line tools on the server and remotely via php. Along with making sure skip-networking was hashed out (and our firewall rubbish), what I had to do was:

1. Try the command line tool on the server hosting the db (e.g. shell> mysql -h localhost -u root -p then enter password)

2. Make a note of the / path it tries to connect from (ending with .sock)

3. Go into my.cnf and make sure in the [client] and [mysqld] sections that socket= contains the path you found in step 2.
