但在 1 月 11 日星期四，从 21:00 开始运行docker compose up --build-d --force-recreate 后，突然出现以下错误。注意：本周早些时候没有发生这种情况，整个星期它都运行正常。

看起来 mpm_event 出了点问题。我想重申一下，我们没有更改 Dockerfile 中的任何内容。

我们已经尝试过的：

  • 删除 mpm_event，构建成功，但应用程序逻辑上不起作用，因为它需要 mpm_event
  • 更新 Docker Desktop
  • 禁用 mpm_prefork 后出现以下错误：ERROR: The following modules depend on mpm_prefork and need to be disabled first: php8.3

答案1

罪魁祸首是软件包php，它会拉动 apache 模块，而该模块默认被激活并启用该mpm_prefork模块。

如果您只使用 php-fpm，则根本不需要它。该php-fpm包会自行安装所需的一切。

或者您只是禁用 php 模块和 mpm_prefork 模块。
