Paso 0 – Actualizar el sistema
sudo apt-get update
sudo apt-get install apache2
Paso 1 – Activar el módulo SSL
sudo a2enmod ssl
sudo service apache2 restart
Paso 2 – Crear un Certificado SSL Autofirmado
sudo mkdir /etc/apache2/ssl
openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/apache2/ssl/apache.key -out /etc/apache2/ssl/apache.crt
Paso 3 – Configurar Apache Para Usar SSL
rm /etc/apache2/sites-available/default-ssl.conf
sudo nano /etc/apache2/sites-available/default-ssl.conf
Debe quedar así
<IfModule mod_ssl.c>
<VirtualHost _default_:443>
ServerAdmin webmaster@ubuntuservidor.edu.ni
ServerName www.ubuntuservidor.edu.ni
DocumentRoot /var/www/html
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined

# SSLCertificateFile /etc/ssl/certs/ssl-cert-snakeoil.pem
# SSLCertificateKeyFile /etc/ssl/private/ssl-cert-snakeoil.key
SSLCertificateFile /etc/apache2/ssl/apache.crt
SSLCertificateKeyFile /etc/apache2/ssl/apache.key
<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>
