PageSpeedはNginxでコンパイルする必要がありますが、Googleページで説明されている方法が気に入らず、従うことにしました。その他素晴らしいです。
とにかくそこでやりました。到着時にservice nginx restartFAILEDエラーが発生しました。
Restarting nginx (via systemctl): Job for nginx.service failed. See 'systemctl status nginx.service' and 'journalctl -xn' for details.

おそらくポート80で何かがリッスンしていると思いました。これは「netstat」出力です：

とにかく、なぜこれが起こるのかわかりません。ゼロ状態のCentOS 7 VPSにインストールしました。そこには他のものがインストールされていません。
よろしくお願いします。
答え1
initスクリプトが実行可能であることを確認してください。
chmod +x /etc/init.d/nginx
また、selinuxの状態を確認してください。次のコマンドを実行して一時的に無効にできます。
setenforce 0
