Apache2は再起動に失敗し、「configtest」は「systemctl status」ログに失敗しました

ターミナルからWebサーバーがダウンした後にApache2を起動しようとしています

Sudo service Apache2 restart

しかし、それは言う

Job for Apache2.service failed because the control process exited with error code. See "systemctl status Apache2.service" and "journalctl -xe" for details.

journalctl -xeを実行してみると

その後、nano /var/log/Apache2/error.logを実行します

私はこれを得た

無効な設定オプションがあります。これが、Apacheが起動できず、'configtest' failedと表示される理由です。実際にsystemctl statusから出力を読み取ることで、通常、このような問題を特定し、ソフトウェアが適切に実行されていない主要な理由を特定するのに十分です。私はいつもそれを見ます。

とはいえ、これはsystemctlステータス出力で詳述されている特定のエラーです。

Nov 11 15:42:06 sd-101534 Apache2[7132]: AH00526: Syntax error on line 12 of /etc/Apache2/mods-enabled/mpm_prefork.conf:

参照するファイル（/etc/Apache2/mods-enabled/mpm_prefork.conf）を編集し、MazClientsをMaxClientsに置き換えてから、Apacheを再起動してください。実際の問題は、MySQLではなくMPM Preforkにあるように思えます。
