MySQL Can Connect Remotely but not Locally

Question

This is a weird problem and I\'m not sure what\'s going on. I installed MySQL on a linux box I have running Ubuntu 10.04 LTS. I can access mysql via SSH mysql -p

Answer 1

In my.cnf, I changed bind-address to 0.0.0.0 and now connections from my node app are correctly accepted.

Answer 2

As the first and good answer says, MySQL isn't listening to your local TCP/IP sockets.

Connect your mysql.Client module using:

client.port = '/tmp/mysql.sock';

and fill in wherever your mysql socket file is located. If you can't find this, consider using this heavy but success-guaranteed system-wide search

cd / ; find * | grep mysql.sock

Answer 3

Manually defining the socket fixed this problem for me.

var client = mysql.createClient({
    user: '(your user here)',
    password: '(your password here)',
    host: '127.0.0.1',
    port: '3306',
    _socket: '/var/run/mysqld/mysqld.sock',
});

Answer 4

I have had similar issues, but with MongoDB. I think you need to make your host point to 127.0.0.1 rather than localhost.

Check:

$ nslookup localhost

and

$ nslookup localhost.

both should return an address of 127.0.0.1

Also check cat /etc/hosts

if localhost maps to ipv6: ::1 localhost then change to 127.0.0.1 localhost

localhost might be pointing to the ipv6 address rather than the ipv4 address.

Hope this helps :)

Answer 5

For me, this problem occurred on an Ubuntu box only accessible on our internal net (though I think this solution applies regardless of the network). I was able to access mysql perfectly well with mysql Workshop and with Node.js mysql plugin from my dev system but not from Node running on the server.

In particular, I tried localhost, 127.0.0.1 or even 'serverName', which was defined as 127... in /etc/hosts. I got nothing but ECONNREFUSED.

Turns out that my mysql instance was set to only accept connections addressed to the server's IP address. That is, it would only accept connections from

{host:'172.xxx.xxx.xxx', user:'blah', ....

Good luck!!

Answer 6

You need to set the socketPath

mysql = require('mysql');
var connection = mysql.createConnection({
    host     : 'localhost',
    user     : 'root',
    password : 'password',
    socketPath  : '/var/run/mysqld/mysqld.sock',

});
