Apache在服务器出现问题时停止所有服务器

我对Apache比较陌生，遇到了一个问题，即当其中一个出现问题时，所有虚拟服务器都会被停止。我们遇到了一个问题，导致后端服务（testing.my domain name.ch）无法进行测试，并导致502错误，apache为我们的生产设施（）提供了相同的错误，尽管它仍在运行（通过使用wget进行验证）

我的httpd.conf文件如下所示：

ServerRoot "/etc/httpd"

anybod可以帮助我理解如何配置当一个虚拟主机宕机时，其他虚拟主机不会宕机的情况吗

非常感谢。

Nic3500-感谢您的回答：

只要所有配置都在同一文件中，就不能在同一进程下运行。如果您想要有一个测试设置，它应该在一个单独的Apache配置下。您可以在同一台计算机上运行两个具有不同配置的实例，只要两个实例不使用相同的端口。或者设置一个VM，您可以将测试配置（或docker，或…）放入其中。您可以在重新启动之前运行apache-t来检查配置。
