issue reiniciando o apache no centos 7

Question

Estou com problemas para reiniciar o apache. Tudo que fiz foi apenas copiar algumas mudanças puxadas dos meus arquivos html do git para o diretório inicial.

isto é o que meu status de apache diz:

   Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled)
   Active: failed (Result: exit-code) since Fri 2017-08-25 02:23:28 EDT; 3min 23s ago
     Docs: man:httpd(8)
           man:apachectl(8)
  Process: 2249 ExecStop=/bin/kill -WINCH ${MAINPID} (code=exited, status=1/FAILURE)
  Process: 2247 ExecStart=/usr/sbin/httpd $OPTIONS -DFOREGROUND (code=exited, status=1/FAILURE)
 Main PID: 2247 (code=exited, status=1/FAILURE)

aqui estão meus registros de erros:
