Trouble with mysql gem on osx 10.6.8

问题:

I'm updating my database from sqlite to mySQL (@mu is too short...I know. I know. I should have done it at the beginning) and running into a problem.

Here's the process so far:

Step 1:

update database.yml and run rake db:schema:load as per this

rake aborted!
Please install the mysql adapter: `gem install activerecord-mysql-adapter` (mysql is not part of the bundle. Add it to Gemfile.)

Step 2:

run rvm @global do gem install mysql

Step 3:

Search SO => Can't install mysql gem on Mac OS X

The solution in this answer didn't work as there is no mySQL directory in /usr/local so I can't edit the code there.

Step 4:

output of mkmf.log => http://pastebin.com/7qSdv73R

Edit 1:

I also ran: gem install activerecord-mysql-adapter

but I still get the same error when running rake db:schema:load:

Rake aborted!
Please install the mysql adapter: `gem install activerecord-mysql-adapter` (mysql is not part of the bundle. Add it to Gemfile.)
...

Edit 2:

Here is database.yml:

development:
  adapter: mysql
  encoding: utf8
  reconnect: false
  database: db/development
  pool: 5
  username: [name]
  password: [password]
  socket: /tmp/mysql.sock
test:
  adapter: mysql
  encoding: utf8
  reconnect: false
  database: db/test
  pool: 5
  username: [name]
  password: [password]
  socket: /tmp/mysql.sock

production:
  adapter: mysql
  encoding: utf8
  reconnect: false
  database: db/production
  pool: 5
  username: [name]
  password: [password]
  socket: /tmp/mysql.sock

I added gem "mysql" to the gemfile and now am getting error

rake aborted!
Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

I don't know what those sockets should be, I filled them in based on a SO post, so that could be part of the problem.

回答1:

Moving Comment to answer.

1.) Answer for Please install the mysql adapter: gem install activerecord-mysql-adapte (mysql is not part of the bundle. Add it to Gemfile.)

ANS: In your database.yml file, The adapter should be mysql2 not mysql

2.) rake aborted! Can't connect to local MySQL server through socket /tmp/mysql.sock (2)

ANS: Find your exact socket file using command

mysqladmin variables | grep socket

If you have password for root, do

mysqladmin -pxxxx variables | grep socket

You wil get the socket file using the above command and just replace it in your database.yml file

Cheers.!!
