[英]rails3 mysql2 GEM does not seem to do TCP, only socket
我猜測的是,當我刪除socket參數時,mysql2沒有默認為TCP連接協議。 你們同意嗎? 任何創業板建議?
我可以通過mysql命令行連接。 所以,從mysql的角度來看,所有配置都是如此。
這行很好地連接:“mysql -P 3406 -u userid -p --protocol = TCP -h localhost”輸入密碼:

database.yml的
svc_development:
adapter: mysql2
encoding: utf8
database: my_db
username: userid
password: apasswd
host: localhost
port: 3406
該端口對於此實例是正確的。 我通過SSH隧道“-L 3406:host:3306”連接到這個數據庫我看了一下itysql2代碼,它沒有采用協議參數。 它只使用套接字。
型號:looky_loo.rb
class LookyLoo < ActiveRecord::Base
self.abstract_class = true
establish_connection "svc_development"
end
從Rails控制台
from script/rails:6:in `<main>'ruby-1.9.2-p136 :002 > LookyLoo.all
Mysql2::Error: Access denied for user 'userid'@'localhost' (using password: YES)

在mysql中,localhost是“魔術”,它意味着使用套接字。 請嘗試使用127.0.0.1。
