由于 PageSpeed 必须与 Nginx 一起编译，并且我不喜欢 Google 页面中的说明方式，因此我决定遵循其他很棒的一个。
无论如何，我在那里做了一切。当我到达 时service nginx restart，我收到了 FAILED 错误：
Restarting nginx (via systemctl): Job for nginx.service failed. See 'systemctl status nginx.service' and 'journalctl -xn' for details.
[FAILED]
systemctl status nginx.service -l输出：
systemctl status nginx.service -l

我想也许有什么东西正在监听端口 80。这是“netstat”输出：

无论如何，我不知道为什么会发生这种情况。我将其安装在处于零状态的 CentOS 7 VPS 上。那里没有安装任何其他东西。
提前致谢。

确保初始化脚本可执行：
chmod +x /etc/init.d/nginx
还要检查 selinux 状态。您可以通过发出以下命令暂时禁用它：
setenforce 0
