postgresql - 使用 dokku pg-plugin 将数据库复制到新的生产环境

标签 postgresql ruby-on-rails-4 pg digital-ocean

从 heroku 转移到 dokku/digital ocean，我使用 pg_dump 将数据库复制到文件“latest.dump”中，并使用 pg_restore 到我的本地 pg db，它工作正常。但是当我尝试运行 dokku postegresql:restore 命令时，它会运行并且我收到“数据库已恢复”但有很多错误并且实际上没有恢复任何数据。关于如何排除故障/导致错误的原因有什么建议吗？

root@domain:~# dokku postgresql:restore db_name < dokku/db/latest.dump

最佳答案

我相信我在尝试完成类似任务时遇到过类似问题。将数据库上传到新堆栈时，您需要使用 .sql 文件。默认情况下，Heroku 会为您提供一个 .dump 文件。对我有用的是使用 .dump 文件将数据库复制到我的本地开发 pg db，然后使用它生成一个 .sql 文件，我将其推送到我的新应用程序。
