Nginx: SPDY SSL Installation and Configuration On a Debian / Ubuntu Linux

To install and configure SPDY SSL on a Debian-based Linux system, such as Ubuntu, you will need to perform the following steps:

1. Install the Nginx web server. You can install Nginx using the apt-get command.

sudo apt-get update
sudo apt-get install nginx

2. Generate a self-signed SSL certificate. You can use the openssl command to generate a self-signed SSL certificate. Replace server.crt and server.key with the desired names for the certificate and private key files, and server_name with the name of the server.

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/nginx/server.key -out /etc/nginx/server.crt -subj "/CN=server_name"

3. Configure Nginx to use the SSL certificate. Edit the Nginx configuration file (usually located at /etc/nginx/nginx.conf) and add the following lines to the server block:

server {
    listen       443 ssl spdy;
    server_name  server_name;

    ssl_certificate      /etc/nginx/server.crt;
    ssl_certificate_key  /etc/nginx/server.key;

    ...
}

4. Restart Nginx to apply the changes. You can do this by running the following command:

sudo systemctl restart nginx

This will configure Nginx to use SPDY SSL on the specified server. Keep in mind that a self-signed SSL certificate is not trusted by most browsers, so you may see security warnings when accessing the site. To avoid these warnings, you should obtain a trusted SSL certificate from a certificate authority.
