向上滚动应该在“FAILED”上方看到更具体的错误。

看起来它不喜欢某个主题/组件。您可能需要运行 ./launcher restart app 来恢复重建前的版本，以便您可以使用常规 UI 来禁用您怀疑的那个，然后再尝试升级。向上滚动是否让您对是哪个组件有所了解？

看起来是 ember CLI 相关的问题。

嘿 @balupton，你能试试更改 EMBER_CLI_PROD_ASSETS: 0 然后再重新构建吗？在我进行上述更改后，我至少有 1 次成功的重新构建。

6

这些似乎是唯一表明有问题相关的日志：

我会试试那个，怎么应用？

算了，找到了：

我现在就去试试。

8

查看更新日志：

我想知道是不是这个：

因为其中一个日志是：

103:M 15 Feb 2022 06:54:18.720 # WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
9

内存不足。

请确保您有足够的（虚拟）内存。如今，1GB 内存和 2GB 交换空间可能不足以进行重建。

10

是的，它奏效了。

nvim /var/discourse/containers/app.yml

env:
  # ...
  ## Workaround for: https://meta.discourse.org/t/failed-to-upgrade-discourse-instance-to-feb-15-2022/218204/7?u=balupton
  EMBER_CLI_PROD_ASSETS: 0
11

Discourse 现在已成功运行，top 目前返回：

KiB Mem : **2041324** total, **287808** free, **1033300** used, **720216** buff/cache
KiB Swap: **0** total, **0** free, **0** used. **581308** avail Mem

这是来自 Scaleway 的 VC1S 服务器：

在以下位置执行建议的更改：

103:M 15 Feb 2022 06:54:18.720 # WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.

也能解决问题吗？

12

该 VPS 有 4GB RAM 和 2GB Swap。

13

你需要添加一些交换空间。看起来你有足够的磁盘空间，所以可以添加 2G 甚至 3G 以确保安全。

我认为 discourse 的标准设置应该已经为你设置好了交换空间。也许可以看看 为你的 Linux 服务器创建交换文件

14

然而，你却看到了内存不足——这很令人担忧。请粘贴 free 命令的输出。

我注意到，在我安装的两个实例（它们都只有1G内存和2G交换空间）中，我曾按照该建议，在 /etc/sysctl.conf 中设置了 vm.overcommit_memory=1。 （但这并不意味着它能解决当前这个问题。）

15

我们将很快移除关闭 Ember CLI 资产的功能，因此请确保尽快解决您的设置问题。否则，在未来的更新中它将再次中断。

您至少需要 1GB RAM + 2GB 交换空间（根据我们的标准安装脚本）

这确实令人担忧——请告知我们您在 free 输出中看到的内容 @itsbhanusharma

17

嘿 @david
这是 free 命令的输出

root@discourse:~# free
              total        used        free      shared  buff/cache   available
Mem:        3932016     3747708       87928       12812       96380        9960
Swap:       2097148     1095852     1001296
18

服务器上还有其他东西在运行吗？对于标准的 Discourse 安装来说，那里的“已用”数字似乎相当高 :thinking:

19 
可用 9960

这可不多 :scream:

你们运行了多少个 unicorn？

20

这是一个多站点 discourse 安装。有几个额外的容器（例如邮件接收器和正常运行时间监视器），但没有什么不寻常的。

UNICORN_WORKERS: 4

21

重启后 free 的输出是什么样的？
