When I restart httpd, I get the following error. What am I missing?

[root@localhost ~]# service httpd restart
Stopping httpd: [ OK ]
Starting httpd: Syntax error on line 22 of /etc/httpd/conf.d/sites.conf:
Invalid command 'SSLEngine', perhaps misspelled or defined by a module not included in the server configuration

I have installed mod_ssl using yum install mod_ssl openssh

Package 1:mod_ssl-2.2.15-15.el6.centos.x86_64 already installed and latest version
Package openssh-5.3p1-70.el6_2.2.x86_64 already installed and latest version

My sites.conf looks like this

<VirtualHost *:80>
# ServerName shop.itmanx.com
 ServerAdmin webmaster@itmanx.com

 DocumentRoot /var/www/html/magento

Probably you do not load the ssl module. You should have a LoadModule directive somewhere in your apache configuration files.

Something like:

LoadModule ssl_module /usr/lib64/apache2-prefork/mod_ssl.so

Usually apache configuration template has (on any distribution) a file called (something like) loadmodule.conf in which you should find a LoadModule directive for each module you load into apache at server start.

On many systems (Ubuntu, Suse, Debian, ...) run the following command to enable Apache's SSL mod:

sudo a2enmod ssl

a2enmod man page

httpd24 solution:

yum install mod24_ssl

On CentOS 7 installing the package "mod_ssl" and restarting the apache server worked for me:

yum install mod_ssl
systemctl restart httpd

On Ubntu 18.04 bionic.

sudo a2enmod ssl; sudo service apache2 restart
