Question

  encoding: utf8
  reconnect: false
  database: twitter_development
  pool: 5

  password:　root
  host: localhost

So, i am sonfused why adapter is mysql2? not mysql?
is this gonna be a problem? I need to change it back to mysql or leave it here?
Thanks.

Answer 1

mysql2 is the modern successor of the mysql gem. Don’t worry, this will work fine for all current MySQL versions.
