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 the command prompt, so I know the user is valid and MySQL is running. But when I try to run
at the command line I get this error:
Can't connect to MySQL server on 'localhost' (10061)
Is something wrong with my database.yml? Here it is:
I've also tried removing the port and socket lines but I still get the same error. Please help. Here are my versions:
developing on Windows 7
MySQL Ver 14.14 distrib 5.5.21 for win64
Server version 5.5.21
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:
Alternately, you can change MySQL's configuration to allow a different bind-address, e.g. localhost instead of 127.0.0.1.
simply change your host to host:127.0.0.1
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".
It's because you don't have password set in your database server(mysql), try this:
development: adapter: mysql2 encoding: utf8 reconnect: false database: bookmobile pool: 5 username: macDaddy password: host: localhost socket: mysql port: 3306
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.
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.
Make sure mysql server is running.
