AH00534: httpd: Kesalahan konfigurasi: Tidak ada MPM yang dimuat

Saya memiliki CentOS Linux release 7.1.1503 (Core)sistem dan saya telah menginstal httpddan file konfigurasi yang sesuai adalah:

#
# 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>
# for a discussion of each configuration directive.

Tetapi saya mengalami masalah ketika mencoba memulai kembali httpsdengan konfigurasi yang dimaksud.

# apachectl configtest
AH00534: httpd: Configuration error: No MPM loaded.

Sementara pada /etc/httpd/conf.modules.d/00-mpm.confmodul MPM dikonfigurasi untuk dimuat:

# Select the MPM module which should be used by uncommenting exactly
# one of the following LoadModule lines:

# prefork MPM: Implements a non-threaded, pre-forking web server
# See: http://httpd.apache.org/docs/2.4/mod/prefork.html
LoadModule mpm_prefork_module modules/mod_mpm_prefork.so

# multi-threaded multi-process web server
# See: http://httpd.apache.org/docs/2.4/mod/worker.html
#
#LoadModule mpm_worker_module modules/mod_mpm_worker.so

# event MPM: A variant of the worker MPM with the goal of consuming
# threads only for connections with active processing
# See: http://httpd.apache.org/docs/2.4/mod/event.html
#
#LoadModule mpm_event_module modules/mod_mpm_event.so

Apakah Anda akan berbaik hati membantu saya memecahkan masalah ini?

(Mencuri dari jawaban jsbillings untuk membantu menyelesaikan masalah ini.)

Sepertinya Anda menggunakan file konfigurasi dari instalasi yang lebih lama (CentOS 6 atau Apache 2.2). File konfigurasi default di CentOS 7 termasuk conf.modules.d/*.confdan kemudian conf.d/*.conf. Modul harus berada di yang pertama, dan konfigurasi lain seperti vhosts harus di yang kedua. Tampaknya file Anda hanya termasuk dir kedua dan bukan modul.

Untuk menemukan modul yang dikomentari, tanyakan saja yum!
