远程mysql：errno：-111，代码：＆＃x27; econnrefused＆＃x27;，syscall：＆＃x27; connect＆＃x27;，地址：＆＃x27.0.0.0.0.0.0.1＆＃x27＆＃x27＆port：3306

Question

在这里进行反应初学者。我刚刚部署了一个应用程序的早期α，目前遇到了此错误-111，从此站点说这是MySQLD仅倾听Localhost接口时发生的问题。我正在使用免费的远程MySQL来测试来自此站点。它说我必须找到我的.cnf并进行修改，以允许除Localhost之外的连接。

1. 如果我使用我无法控制的免费远程mysql，它将起作用吗？
2. 如果我尝试另一项可能有所不同的免费远程MYSQL服务，它将起作用？
