ec2 Apache 服务器 http-500 故障排除

ec2 Apache 服务器 http-500 故障排除

我的网站有点怪异,所以我重启了服务器。我还运行了 sudo yum update 并更新了所有内容。现在我的网站无法加载(www.kisnardonline.com),并且出现 http-500 错误。我不能 100% 确定这是否与更新有关。我在 Google 上搜索了很多,但不知道还要看什么。

看起来更新没有覆盖我的配置文件,所以我不确定可能出了什么问题?

我能够通过 SSH 连接到我的服务器。我能够连接到我的 MySQL 数据库。我能够运行我的 Java 游戏服务器并从我的本地 PC 连接到我的游戏客户端。顶部输出对我来说看起来不错(内存和 CPU 充足)。还有什么我可以检查的吗?
