How to bind SSL certificate having crt file - apache

Question

I'm installing SSL certificate in my website and I tried following steps but still not website not working in https and still working on http
I already bind my crt file in below
<VirtualHost _default_:443>
DocumentRoot /var/www/http
ServerName my_domain.com
SSLEngine on
SSLCertificateFile /path/to/coolexample.crt
SSLCertificateKeyFile /path/to/privatekey.key
SSLCertificateChainFile /path/to/intermediate.crt
<FilesMatch "\.(cgi|shtml|phtml|php)$">
SSLOptions +StdEnvVars
</FilesMatch>
<Directory /usr/lib/cgi-bin>
SSLOptions +StdEnvVars
</Directory>
BrowserMatch "MSIE [2-6]" \
nokeepalive ssl-unclean-shutdown \
downgrade-1.0 force-response-1.0
BrowserMatch "MSIE [17-9]" ssl-unclean-shutdown
</VirtualHost>
After type this command apache2ctl configtest
it shows Syntax OK
But after type last command apache2ctl restart
It shows following error message
httpd not running, trying to start
(13)Permission denied: AH00072: make_sock: could not bind to address [::]:80
(13)Permission denied: AH00072: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
AH00015: Unable to open logs
Action 'restart' failed.
The Apache error log may have more information.

To activate SSL encryption you need an extra VirtualHost for port 443. This is often done within Apache/conf/extra/httpd-ssl.conf which is platform dependend.
Within such a file you need an entry like (Windows example):
<VirtualHost *:443>
DocumentRoot "C:/webserver/html/my_html"
ServerName www.example.com
Protocols h2 http/1.1
SSLEngine on
SSLProtocol all -SSLv2 -SSLv3
