Apacheを再起動できません

私はフォローしていますデジタル海洋ネットワークサブドメイン設定ガイドです。しかし、今Apacheの再起動に問題があります。

次のエラーがあります。

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

systemctl status httpd.service私にこれを与えた：

● httpd.service - The Apache HTTP Server
   Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled)
   Active: failed (Result: exit-code) since Wed 2018-04-18 18:11:36 UTC; 12s ago
     Docs: man:httpd(8)
           man:apachectl(8)

Apr 18 18:11:36 web-server systemd[1]: Unit httpd.service entered failed state.

だから私はsudo tail /var/log/httpd/error_logを実行して次の結果を得ました。

(21)Is a directory: AH00091: httpd: could not open error log file /var/www/motomart.my.
AH00015: Unable to open logs

この問題を解決するのに役立つ親切な人はいますか？私はとても新しく、次に何をすべきかわかりません。

Apacheの構成フラグメントは次のとおりです。

<VirtualHost *:80>
    ServerName portal.motomart.my
    ServerAlias www.portal.motomart.my
    DocumentRoot /var/www/motomart.my/public_html
    ErrorLog /var/www/motomart.my/error.log
    CustomLog /var/www/motomart.my/requests.log combined
</VirtualHost>
