Installing Grebe - Jul 30, 2014

Documenting the steps, which will lead to additional programming changes to make it simpler.

* With the hosting provider, add DNS information, if necessary. 
* Create a CNAME record if installing the code under a subdomain. 
** <code>grebe @</code>

* Log onto remote server.

* Change to user @root.@ or use @sudo@ ahead of each command.

* Change directory to web server config area. This example uses the Nginx web server, and it assumes that FastCGI has been installed.
** @cd /etc/nginx@

* Need to create a server block config file to support Grebe. 
** http://wiki.nginx.org/ServerBlockExample
*** _"VirtualHost" is an Apache term. Nginx does not have Virtual hosts, it has "Server Blocks" that use the server_name and listen directives to bind to tcp sockets._
* This is an example of using Grebe under a subdomain.
** @cd sites-available@
** @vim grebe.yourdomain.com@
** add the following and save the file:

code.

server {
        listen   80;

        server_name grebe.yourdomain.com;

        location ~ ^/(css/|javascript/|images/) {

          expires max;
        }

        location /api/v1 {
             root /home/grebe/Grebe/root/api/v1;
             index grebeapi.pl;
             rewrite  ^/(.*)$ /grebeapi.pl?query=$1 break;
             fastcgi_pass  127.0.0.1:8999;
             fastcgi_index grebeapi.pl;
             fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
             include fastcgi_params;
        }

        location / {
             root /home/grebe/Grebe/root;
             index grebe.pl;
             rewrite  ^/(.*)$ /grebe.pl?query=$1 break;
             fastcgi_pass  127.0.0.1:8999;
             fastcgi_index grebe.pl;
             fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
             include fastcgi_params;
        }
}
code..

* Create a link to the new Nginx server block file.
** @ln -s /etc/nginx/sites-available/grebe.yourdomain.com /etc/nginx/sites-enabled/@

* Restart Nginx.
** @/etc/init.d/nginx restart@

* Create a home directory for Grebe.
** @cd /home@
** @mkdir /home/grebe@
