参考了https://github.com/brianmario/mysql2mysql2，单独使用 这个 gem，新建一文件 app.rb，里面单独写 require 'mysql2' 执行后，报 mysql2.bundle: [BUG] Segmentation fault 错误
ruby 版本 1.9.3，Google 了一会，有说换 mysql 版本的，不太现实吧，求解。

只是 require 一个 mysql2 ? 我也是 ruby 1.9.3，我这边是 ok 的，你应该给多点信息
require "mysql2"
require "active_record"
# 数据库名,ip,数据库用户名,数据库对应用户名的密码
def connect_db(*args)
db = args[0]
ip = args[1] || "127.0.0.1"
user = args[2] || "root"
password = args[3] || ""
ActiveRecord::Base.establish_connection(
:adapter => "mysql2",
:database => db,
:encoding => "utf8",
:port => 3306,
:host => ip,
:username => user,
:password => password,
)
end
