答え1

問題はApache設定ファイルの構文エラーのようです。エラーログを確認してください（一般的な内容/var/log/httpd/error_logまたは/var/log/apache2/error_log詳細については）。エラーを修正すると、Apacheサーバーが起動する可能性があります。

答え2

以下を使用して構成ファイルの構文を確認できます。

apachectl configtest

~からhttps://httpd.apache.org/docs/2.4/programs/apachectl.html:

configtest
Run a configuration file syntax test. It parses the configuration files and either reports Syntax Ok or detailed information about the particular syntax error. This is equivalent to apachectl -t.
