Installing Grebe

Instructions as of July 30, 2014.

Documenting the steps, which will lead to additional programming changes to make it simpler. These instructions include creating a subdomain, Nginx server block, and setting up MySql. Some of this info may be split out into another file.

DNS

With the hosting provider, add DNS information, if necessary.

Create a CNAME record if installing the code under a subdomain.
grebe CNAME @

May have to wait a while before DNS updates in order to use the new subdomain website.

Nginx

Log onto remote server.

Change to user root or use sudo ahead of each command. https://help.ubuntu.com/community/RootSudo

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:

########
# GREBE
########

server {
        listen   80;

        server_name grebe.yourdomain.com;

        location ~ ^/(css/|javascript/|images/) {
          root /home/grebe/Grebe/root;
          access_log off;
          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;
        }
}

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

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

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

• Change to Grebe directory. ** @cd /home/grebe@

• Create directories that will host markup and HTML template files that represent the posts created. These directories exist outside of document root, but they are used by the Grebe code. * @mkdir posts@ * @mkdir markup@

• Within the @/home/grebe@ directory, download or copy over the gzipped tar file that contains the Grebe code, and unpack it. Example file: @Grebe-29Jul2014.tar.gz@ * unpack in two steps: @gunzip Grebe-29Jul2014.tar.gz@ @tar xvf Grebe29Jul2014.tar@ or unpack in one step: @tar zxvf Grebe29Jul2014.tar.gz@

• The unpacking creates a directory called @Grebe@.

• Change ownership of all contents under the Grebe directory to the owner (username) and group that Nginx operates under. ** @chown - R owner:group Grebe@

• While in @/home/grebe@ change directory to @Grebe@. ** @cd Grebe@

• For curiosity sake, show a listing of all files and subdirectories under Grebe: ** @ls -lR@

• The directory structure under Grebe: * lib API Client Config CPAN * Algorithm HTML JSON REST Text URI Escape XML YAML JRS * nginx root api v1 css images javascript splitscreen sql t tmpl * yaml

• While at @/home/grebe/Grebe@, change to the web root directory. ** @cd root@

• Edit the small file @grebe.pl@. Here is the entire file. Ensure of the proper directory structures after the @lib@ commands.

#!/usr/bin/perl -wT
use strict;
$|++;
use lib '/home/grebe/Grebe/lib';
use lib '/home/grebe/Grebe/lib/CPAN';
use Client::Dispatch;
Client::Dispatch::execute();

• While in @/home/grebe/Grebe/root@, change directory to the version one API directory. Since we're under the web root directory for the Nginx web server, this directory is part of the API URL. ** @cd api/v1@

• Edit the small file @grebeapi.pl@. Here is the entire file. Ensure of the proper directory structures after the @lib@ commands.

#!/usr/bin/perl -wT
use strict;
$|++;
use lib '/home/grebe/Grebe/lib';
use lib '/home/grebe/Grebe/lib/CPAN';
use API::DispatchAPI;
API::DispatchAPI::execute();

• Change to the directory that contains the database files. ** @cd /home/grebe/Grebe/sql@

• This assumes that MySQL is installed.

• Create a new database and database user for Grebe. If planning to use an existing database, then skip these steps.

• Enter this command to get into the mysql command line interface: (it will ask for the root password) ** @mysql -uroot -p@

• At the @mysql>@ prompt, enter the following commands, one at a time: * @create database grebe;@ create user 'grebe'@'localhost' identified by 'set_your_password_here'; grant all privileges on grebe. to 'grebe'@'localhost'; * @flush privileges;@ * @quit;@

• Create the Grebe database tables. * @mysql ugrebe -pyourpassword -D grebe < grebeusers.sql@ @mysql ugrebe -pyourpassword -D grebe < grebeposts.sql@ @mysql ugrebe -pyourpassword -D grebe < grebetags.sql@ * @mysql ugrebe -pyourpassword -D grebe < grebesessionids.sql@

• Change directory to the location of the Config module. ** @cd /home/grebe/Grebe/lib/Config@

• Edit @Config.pm@ and make the appropriate directory location change for the variable @$yml_file@ which points to the location of the Yaml configuration file. ** @my $yml_file = "/home/grebe/Grebe/yaml/grebe.yml";@

• Change directory to the Yaml config file location. * @cd /home/grebe/Grebe/yaml@ For testing, enable debug mode. ** @debug_mode: 1@

• Edit the file @grebe.yml@ and make the appropriate changes.

• If @read_template: 1@, then the following files need linked from the @Grebe/tmpl@ directory to the @posts@ directory. * @ln -s /home/grebe/Grebe/tmpl/header.tmpl /home/grebe/posts@ @ln -s /home/grebe/Grebe/tmpl/inc_headernav.tmpl /home/grebe/posts@ * @ln -s /home/grebe/Grebe/tmpl/footer.tmpl /home/grebe/posts@

• Open web browser and enter the following URL: ** @http://grebe.yourname.com@

• The site or blog app should load, displaying the default image header and other links.

• Create a user account: ** @http://grebe.yourname.com/signup@

• Login: ** @http://grebe.yourname.com/login@
