How To Create a SSL Certificate on Apache for Ubuntu 12.04
About SSL Certificates
A SSL certificate is a way to encrypt a site's information and create a more secure connection. Additionally, the certificate can show the virtual private server's identification information to site visitors. Certificate Authorities can issue SSL certificates that verify the server's details while a self-signed certificate has no 3rd party corroboration.
The steps in this tutorial require
the user to have root privileges on the server. You can see how to set that up
here in steps 3 and 4.
sudo apt-get install apache2
Step One—Activate the SSL Module
The next step is to enable SSL on the control panel.
sudo a2enmod sslFollow up by restarting Apache.
sudo service apache2 restart
Step Two—Create a New Directory
We need to create a new directory where we will store the server key and certificate
sudo mkdir /etc/apache2/ssl
Step Three—Create a Self Signed SSL Certificate
When we request a new certificate, we can specify how long the certificate should remain valid by changing the 365 to the number of days we prefer. As it stands this certificate will expire after one year.
sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/apache2/ssl/apache.key -out /etc/apache2/ssl/apache.crtWith this command, we will be both creating the self-signed SSL certificate and the server key that protects it, and placing both of them into the new directory.
This command will prompt terminal to display a lists of fields that need to be
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
Country Name (2 letter code) [AU]:US
State or Province Name (full name) [Some-State]:New York
Locality Name (eg, city) :NYC
Organization Name (eg, company) [Internet Widgits Pty Ltd]:Awesome Inc
Organizational Unit Name (eg, section) :Dept of Merriment
Common Name (e.g. server FQDN or YOUR name) :example.com
Email Address :firstname.lastname@example.org
Step Four—Set Up the Certificate
Now we have all of the required
components of the finished certificate.The next thing to do is to set up the
virtual hosts to display the new certificate.
nano /etc/apache2/sites-available/default-sslWithin the section that begins with <VirtualHost _default_:443>, quickly make the following changes.
Add a line with your server name right below the Server Admin email:
ServerName example.com:443Replace example.com with your DNS approved domain name or server IP address (it should be the same as the common name on the certificate).
Find the following three lines, and make sure that they match the extensions below:
Save and Exit out of the file.
Step Five—Activate the New Virtual Host
Before the website that will come on the 443 port can be activated, we need to enable that Virtual Host:
sudo a2ensite default-sslYou are all set. Restarting your Apache server will reload it with all of your changes in place.
sudo service apache2 reloadIn your browser, type https://youraddress, and you will be able to see the new certificate.
