I am developing a strategy game for web where there there will be a lot of client-server traffic for sending attacks, moves, etc. Right now I send messages from the client to the server via HTTP, and I want to try and setup SSL on my Ubuntu server which already has a LAMP stack installed and running.
Here are the guides I've followed:
- https://help.ubuntu.com/10.04/serverguide/httpd.html (I used this to enable SSL)
- https://help.ubuntu.com/12.04/serverguide/certificates-and-security.html (I followed this one first to generate the private and public keys)
After I installed the keys, I tried hitting my page using the https:// prefix, but I got an error:
SSL connection error. Unable to make a secure connection to the server. This may be a problem with the server, or it may be requiring a client authentication certificate that you don't have. Error code: ERR_SSL_PROTOCOL_ERROR
After I received this error, I tried following: https://www.debian-administration.org/articles/349
This lead me around to modifying my 'ports.conf' file which now looks like:
NameVirtualHost *:80
Listen 80
<IfModule mod_ssl.c>
NameVirtualHost *:443
Listen 443
</IfModule>
<IfModule mod_gnutls.c>
NameVirtualHost *:443
Listen 443
</IfModule>
I restarted Apache successfully, and I can still hit my pages using HTTP, but not HTTPS (receiving the same error as before).
What step(s) am I missing?
sudo a2enmod sslyet? No harm in running the command a second time to check. Also, I've found the DigitalOcean documentation for setting up SSL to be easier to follow and more complete.
