Rails:生产Rails控制台无法启动 [英] Rails: Production Rails console won't start

问题描述

在我的OS X开发笔记本电脑上一切正常.

Everything works fine on my OS X development laptop.

将应用程序部署到生产环境中，它将按预期运行并显示数据.

Deploy the app to production and it runs and displays data as expected.

但是，当我尝试在生产服务器上运行Rails 控制台时，出现错误...

However, when I try to run the Rails console on the production server I get an error...

$ rails console -e production
/opt/deployed_rails_apps/con_app_rails_3/shared/bundle/ruby/1.9.1/gems/mysql2-0.3.11/lib/mysql2/client.rb:44:
    in `connect': Can't connect to local MySQL server through socket 
        '/tmp/mysql.sock' (2) (Mysql2::Error)

    from /opt/deployed_rails_apps/con_app_rails_3/shared/bundle/ruby/1.9.1/gems/mysql2-0.3.11/lib/mysql2/client.rb:44:in `initialize'
    from /opt/deployed_rails_apps/con_app_rails_3/shared/bundle/ruby/1.9.1/gems/activerecord-3.2.2/lib/active_record/connection_adapters/mysql2_adapter.rb:16:in `new'

我尝试从database.yml中删除socket: /tmp/mysql.sock-相同的结果.

I tried removing socket: /tmp/mysql.sock from database.yml -- same result.

尽管该应用程序可以运行，但我确实需要能够访问生产环境中的控制台以执行某些任务.

Although the app runs, I do need to be able to access the console in production as well to perform certain tasks.

我能够使用MySQL命令行客户端连接到MySQL服务器.

I am able to connect to the MySQL server using the MySQL command line client.
