好吧，我对这一切还有些陌生。
我试图在我的本地主机上运行 php 和 apache2，但似乎无法让它工作。
当我在我的计算机上将 localhost 输入 chrome 时，我不断收到此消息：
服务暂时不可用
由于维护停机或容量问题，服务器暂时无法满足您的请求。请稍后重试。
我已找到并将错误日志粘贴在下面：

不太清楚该如何处理，但我真的很想立即开始运行。
提前感谢你的帮助。
答案1
Apache 正在尝试连接到fe80::1端口 20559 上的上游代理，但该地址/端口上没有运行任何服务。由于没有运行任何服务，Apache 收到Connection refused并返回 503 错误。
要解决此问题，请启动服务或使用正确的 IP 地址/端口号（如果适用）。（这不太可能fe80::1是正确的地址。）
