Ich habe ein CentOS Linux release 7.1.1503 (Core)System und ich habe installiert httpdund die entsprechende Konfigurationsdatei ist:

#
# This is the main rConfig Apache server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs/2.2/> for detailed information.
# In particular, see
# <URL:http://httpd.apache.org/docs/2.2/mod/directives.html>

Beim Versuch, httpsmit der fraglichen Konfiguration neu zu starten, treten jedoch Probleme auf .

# apachectl configtest

Würden Sie mir bei der Lösung dieses Problems so behilflich sein?

(Stehlen aus der Antwort von jsbillings , um dieses Problem zu lösen.)

Anscheinend verwenden Sie eine Konfigurationsdatei aus einer älteren Installation (CentOS 6 oder Apache 2.2). Die Standard-Konfigurationsdatei in CentOS 7 enthält conf.modules.d/*.confund dann conf.d/*.conf. Module sollten sich in der ersten und andere Konfigurationen wie vhosts in der zweiten befinden. Es scheint, dass Ihre Datei nur das zweite und nicht das Modulverzeichnis enthält.

Fragen yumSie einfach nach den auskommentierten Modulen !
