Setting up SSL with Apache2
Once the server is installed you need to do three things to get a working SSL setup:
- Generate, or import, a certificate.
- Enable Apaches SSL support.
- Configure your SSL options.
Generate self-signed certificate
Create a certificate:
mkdir /etc/apache2/ssl openssl req -x509 -nodes -days 1825 -newkey rsa:2048 -keyout /etc/apache2/ssl/apache.key -out /etc/apache2/ssl/apache.crt
Enabling SSL Support
To use the SSL facilities of Apache2 you must enable the module mod_ssl
Create a SSL conf. file (if needed) and establish a necessary symlink.
If you do not have SSL conf file (/etc/apache2/sites-available/default-ssl) need to copy the 'default' conf as a stub for the 'default-ssl' conf.
cp /etc/apache2/sites-available/default /etc/apache2/sites-available/default-ssl
Next, establish a symlink from the 'available' default-ssl file to the 'enabled' file.
ln -s /etc/apache2/sites-available/default-ssl /etc/apache2/sites-enabled/000-default-ssl
Instruct Apache to listen to 443
Change the port address in /etc/apache2/ports.conf by default it will listen port 80 and now we are installing with SSL we need to change port 443 to listen
Your ports.conf may already have an IfModule clause in it for the SSL portion. If you see this, you can just leave it as-is:
<IfModule mod_ssl.c> Listen 443 </IfModule>
With these two steps out of the way you now have an Apache setup which will listen for and accept SSL connections. The next step is to modify your virtualhosts to use it.
Configuring your SSL Hosts
The final step is to ensure that your virtual hosts, or main host, will accept SSL options
Configure HTTPS over port 443 (edit /etc/apache2/sites-available/default-ssl):
NameVirtualHost *:443 (Note: Look down just a bit and make a change to the virtual host settings.) <VirtualHost *:443> ServerName localhost DocumentRoot /var/www-ssl/html/ (Note: Again, use your assigned IP or a DNS name followed with ":443" if you have one for ServerName.)
Turn on the SSL engine.
Make sure the following are in your default-ssl file. The SSLengine should be on, and the cert and key should be properly path-ed:
SSLEngine On SSLCertificateFile /etc/apache2/ssl/apache.crt SSLCertificateKeyFile /etc/apache2/ssl/apache.key
