Rails development - Can't connect to MySQL server on 'localhost' (10061)

Question

I\'m a Rails developer newbie using MySQL as the database. I can successfully connect to MySQL using the command:

MySQL -u macDaddy -p

at t

Answer 1

simply change your host to host:127.0.0.1

Answer 2

I had a similar error but it was because the port: 3306 was missing in the database.yml. Once I added port: 3306 issue was resolved.

Answer 3

Make sure mysql server is running.

Answer 4

Change the value of host in the database.yml to be "127.0.0.1" will work. Or,you can modify your pc's hosts file, add an item as "localhost 127.0.0.1".

Answer 5

make sure the port number that you have set while creating MySQL(e.g.: 7777), please add port number with appropriate 'username' and 'password'.

default: &default
  adapter: mysql2
  encoding: utf8
  pool: 5
  username: root
  password: admin
  host: localhost
  port: 7777

in the database.yml in config directory of your app directory.

Answer 6

My best guess is that the machine, which you indicated as Windows, has IPv6 networking enabled. Thus when you try to go to localhost, it is resolving to "::1". This is in fact the local machine, however, default MySQL installs normally have bind-address set to 127.0.0.1, which would cause localhost to fail in this setup.

You might be able to verify this by running ping localhost from the command prompt, and seeing if you get a response like:

 Reply from ::1: time<1ms

To fix this, you can change your config to specify:

 host: 127.0.0.1

Alternately, you can change MySQL's configuration to allow a different bind-address, e.g. localhost instead of 127.0.0.1.
