因所有权问题而失败的维护不善服务器重建 - 寻求帮助

1

Hello, and thanks for reading! Our community lost its primary technical administrator, and because of that they have created a single point of failure for us in a number of ways. Recently, one of the admins noticed that transactional emails were no longer being delivered, and I am the only active person remaining with any systems administration experience.

However, one member had ownership of our cloud server and was responsible for payments so we were able to gain root access to our Discourse server.

We originally thought that we could make a local backup, but S3 is configured so the local backups steps wouldn’t work and our last local backup is 2019.

While backups on S3 are as recent as last week we do not have access to the S3 bucket. Our remaining admin supposedly gets the emails, but whether he can download them without authentication to S3 is an open question.

At this point, we decided we could either attempt a rebuild, or reconfigure the mail services to a new SendGrid account - we were already using SendGrid but didn’t know the info.

I decided to attempt a rebuild since, for whatever reason in my mind, it seemed like a more reliable option for potentially resolving errors and was inevitably needed.

It failed with the following output:

I am assuming that these errors are the primary reason?

error discourse@: The engine "node" is incompatible with this module. Expected version ">= 20". Got "18.15.0"
error discourse@: The engine "yarn" is incompatible with this module. Expected version "please-use-pnpm". Got "1.22.19"
warning discourse@: The engine "pnpm" appears to be invalid.

I then attempted to update these modules using npm. I installed npm on the discourse server, and tried to upgrade yarn, but needed node as a dependency. I tried to upgrade node, and received an error that a particular file required administrative access during the install, and I needed to run a chown command to change privileges. I did that, but it made no difference.

That’s ultimately where we stopped.

Here’s my ask:

  1. If we do get this yarn / node thing situation updated, will that resolve the rebuild error? How do we do that?

  2. Is there any way I can compel the server to make a local backup now, outside of S3? If I can do that, we may just abandon ship and restore to a new Discourse hosted server.

  3. Are there paid discourse services that could help us? My time is almost non-existent and I want our community to be saved even if it costs us a bit.

Lastly, the server is running Ubuntu 20.04. Additionally, we have this as our plugin list -

==================== PLUGINS ====================
          - git clone https://github.com/discourse/docker_manager.git
          - git clone https://github.com/discourse/discourse-spoiler-alert.git
          - git clone https://github.com/discourse/discourse-data-explorer.git
          - git clone https://github.com/merefield/discourse-onebox-assistant.git

WARNING:
You have what appear to be non-official plugins.
If you are having trouble, you should disable them and try rebuilding again.

See https://github.com/discourse/discourse/blob/main/lib/plugin/metadata.rb for the official list.

But I am presuming these have nothing to do with the failed rebuild.

Thank you for your help.

如果备份在那里，您就可以访问它。是的，拥有该存储桶的人也可以访问。

如果您想了解第三方付费服务，请随时在#marketplace（市场）板块发帖。

这真是一个棘手的处境——我同情你。

就我个人而言，我非常希望在尝试重建之前获得一个备份。如果常规备份过程对你没有用（因为它将备份发送到无法访问的地方），那么我会想办法使用命令行进行数据库备份，但我不太确定具体方法。也许是在 Docker 中使用 pg_dump？

或者，也许你可以使用你的命令行访问权限将备份重定向到本地磁盘而不是 S3。

但在这两种情况下，你都需要足够的本地磁盘空间。

编辑：与 Jay 的帖子交叉了。

谢谢——我的想法是，如果我们能做一个备份，那就是将备份重定向到本地磁盘而不是 S3，这样我们就有空间了。

这是我的错，昨晚我没有弄清楚本地备份，而是进行了重建——事后看来，这很清楚。我低估了重建的影响。

6

你能帮我理解一下吗？您的意思是，如果备份被路由到那里，就必须存在凭据？（我们确实确认了我们的 Discourse 管理面板中出现了一个新的备份）

问题是，如果我们需要的凭据来访问备份，我认为除了那个消失的家伙之外，没有人真正拥有这些凭据。

如果 literatecomputing 承担这项工作，他们能否获取本地备份并将我们现有的站点恢复到新的维护服务器上？

7

如果 S3 存储桶有上周的备份，那么 Discourse 就拥有该存储桶的凭证。它们可能在 app.yml 或站点设置中。

但您不需要自己访问 S3 存储桶，您应该能够通过 Discourse 下载备份。

您是否在 /admin/backups 中看到了备份？
如果看到了，尝试下载它们时会发生什么？
您也可以将站点设置 - 备份 - 备份位置更改为“本地存储”。

是的。如果你备份到 S3，凭据就在你的数据库或 yml 文件中。

是的。在 SiteSettings 或 yml 文件中都有 backup_location 设置。如果它在 SiteSettings 中而不是在数据库中，那么会比较困难，但并非不可能更改。

我只是个新手，但根据最近的帖子报告的关于重建时文件的所有权问题，您是否可以：

如果您有命令行访问权限，为什么不进行命令行备份？

10

我有 root 访问权限。我确实执行了命令行备份，但它已推送到 S3。感谢 @pfaffman 的评论，我现在意识到我可以尝试将备份从 S3 拉取到本地 - 我只需要时间去尝试。

11

您在用户体验（UX）的设置中看到了 backup_location 这个设置吗（或者服务器宕机了，所以您看不到？）

您是指这个警告吗？

WARNING: containers/app.yml 文件是可被所有人读取的。您可以通过运行以下命令来保护此文件：chmod o-rwx containers/app.yml

这是一个警告。多年来，默认情况下该文件是可被所有人读取的（假设大多数自托管者只会以 root 用户登录，并且没有其他用户），但后来有人认为该文件中包含的秘密信息可被任何人读取不是最佳实践。由于您以 root 用户身份运行启动器，root 用户始终能够读取该文件。

我没有看到 admin/backups，它在哪里？我唯一看到 backups 的地方是 /var/discourse/shared/standalone/backups/default，但这些都是很久以前的本地备份。

14

我稍后会跟进网站设置的情况，等能访问的人醒来（他们是英国时间）。我推测他们没有访问权限，因为网站宕机了。

我没有在 app.yml 文件中看到特定的 backup_location 设置。

另外，侧边栏，但我看到你们公司简介里说你曾是一名 CS 老师。那是我目前的正职 :smiley:

不是那个。等我有机会时我会贴出具体的错误，但正如我所说，那是在尝试升级节点时出现的，而不是在重建过程中。

将此添加到您的论坛 URL。您应该可以在用户界面中看到您的备份。

明白了。我一直在服务器上查找这个。网站已完全瘫痪，所以我无法访问该页面。

只是一个一般性问题。服务器的规格是什么？包括操作系统版本。

18

这是一个很久以前[^1]的镜像，很可能是导致这些错误的原因：

[^1]：以互联网时间计算

你可能需要 git pull discourse_docker 目录（你运行 launcher 的目录）。

像往常一样，由于你处于降级状态，请先备份服务器。

我们今天设法完成了一个本地新备份，我现在正在本地下载它。

所以，我将 pull /var/discourse，然后尝试重建以进行更新？

Your branch and 'origin/main' have diverged,
and have 15 and 201 different commits each, respectively.
  (use "git pull" to merge the remote branch into yours)

diverged 确实是轻描淡写了 :smile:

我猜你一直在提交容器配置，所以 git pull 或 git pull --rebase 可能 会让你达到目的，不妨试试 :+1:

21

我的朋友，我不知道发生了什么，但如果需要的话，我会看看通过拉取或变基能得到什么。我将创建一个新的维护窗口，因为出于某种原因，网站确实恢复到了旧版本。我会向大家更新结果。

我真的很感激所有的智慧！
