service httpdの失敗

Question

###前提・実現したいこと
自宅PCでWEBサーバを立てて勉強中です。
オレオレ証明書&秘密鍵を作成し、/etc/httpd/conf/に配置後、
service rehttpdとしたところ、エラーが出ました。
それまでhttpで接続できていたのが、接続不可となりました。

エラーメッセージ
[root@localhost ~]# service httpd start
Redirecting to /bin/systemctl start httpd.service
Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.
[root@localhost ~]# systemctl status httpd.service

Process: 47118 ExecStart=/usr/sbin/httpd $OPTIONS -DFOREGROUND (code=exited, status=1/FAILURE)
Main PID: 47118 (code=exited, status=1/FAILURE)

Linuxについては初心者で、とても初歩的な質問で大変恐縮です。
切り分けに必要な情報が不足していれば、ご教示ください。

よろしくお願いします。

/var/log/messages や /var/log/httpd 以下にエラーの原因が記述されていないでしょうか？

質問欄のエラーメッセージ全体を範囲指定して<code>をクリックしてください。また、追加のログ情報もここや回答欄に書かずに、質問に追記してください。

勉強中とのことなので、ログの場所はわかったと思いますので、error を自分の力で解消してみるのがよいと思います！
