我目前仍然坚持使用rails项目的(我希望是一个新的)问题(这是我的第一个rails项目,所以如果我错过了任何关键的话我会道歉).我已经在这里呆了几个小时,似乎找不到任何解决方案.我已经尝试过以下线程的解决方案但无济于事.
connect to local MySQL server through socket
Can’t connect to local MySQL server through socket
Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’ (2)
Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’
列表还在继续,无论如何,有些线程与我的情况相似,其他人只是抓着稻草.让我快速概述一下我的情况.
>该项目是在mac上开发的
>我最近建立了一个测试服务器作为学习部署过程的手段
>服务器正在运行Ubuntu Server 12.04
我设法按照一些教程进行设置,包括Capistrano部署教程,直至：
$rake RAILS_ENV=production db:schema:load
如果我用–trace运行它,我得到以下输出：
** Invoke db:schema:load (first_time)
** Invoke environment (first_time)
** Execute environment
rake aborted!

请注意,我已经更改了套接字变量的位置,以便与我认为是ubuntu上的.sock文件相对应,因为这与mac OSX上的标准安装不同.
最后,我在运行时也遇到了同样的错误
