Instalar phpmyadmin en trixbox

go to the TB menu (http://IP_address_of_TB_2.2_here/maint/index.php?packages)

Once you are there, scroll down until you find the module labeled “tbm-phpmyadmin.noarch”
click the check box on the right hand side, scroll down and click on the Install button.

No se puede hacer via yum, por lo menos yo no pude en mi distribucion, la otra alternativa es bajarlo de la pagina:

http://www.phpmyadmin.net/home_page/index.php

Y seguir algunas sencillas instrucciones para configurar adecuadamente:

1. Choose an appropriate distribution kit from the phpmyadmin.net Downloads page. Some kits contain only the English messages, others contain all languages in UTF-8 format (this should be fine in most situations), others contain all languages and all character sets. We’ll assume you chose a kit whose name looks like phpMyAdmin-x.x.x-all-languages.tar.gz.
2. Untar or unzip the distribution (be sure to unzip the subdirectories): tar -xzvf phpMyAdmin_x.x.x-all-languages.tar.gz in your webserver’s document root. If you don’t have direct access to your document root, put the files in a directory on your local machine, and, after step 4, transfer the directory on your web server using, for example, ftp.
3. Ensure that all the scripts have the appropriate owner (if PHP is running in safe mode, having some scripts with an owner different from the owner of other scripts will be a problem). See FAQ 4.2 and FAQ 1.26 for suggestions.
4. Now you must configure your installation. There are two methods that can be used. Traditionally, users have hand-edited a copy of config.inc.php, but now a wizard-style setup script is provided for those who prefer a graphical installation. Creating a config.inc.php is still a quick way to get started and needed for some advanced features.
   • To manually create the file, simply use your text editor to create the file config.inc.php (you can copy config.sample.inc.php to get minimal configuration file) in the main (top-level) phpMyAdmin directory (the one that contains index.php). phpMyAdmin first loads libraries/config.default.php and then overrides those values with anything found in config.inc.php. If the default value is okay for a particular setting, there is no need to include it in config.inc.php. You’ll need a few directives to get going, a simple configuration may look like this:

     <?php
     $cfg['blowfish_secret'] = 'ba17c1ec07d65003';  // use here a value of your choice
     
     $i=0;
     $i++;
     $cfg['Servers'][$i]['auth_type']     = 'cookie';
     ?>
     

     Or, if you prefer to not be prompted every time you log in:

     <?php
     
     $i=0;
     $i++;
     $cfg['Servers'][$i]['user']          = 'root';
     $cfg['Servers'][$i]['password']      = 'cbb74bc'; // use here your password
     ?>
     

     For a full explanation of possible configuration values, see the Configuration Section of this document.

   • Instead of manually editing config.inc.php, you can use the Setup Script. First you must manually create a folder config in the phpMyAdmin directory. This is a security measure. On a Linux/Unix system you can use the following commands:

     cd phpMyAdmin
     mkdir config                        # create directory for saving
     chmod o+rw config                   # give it world writable permissions
     

     And to edit an existing configuration, copy it over first:

     cp config.inc.php config/           # copy current configuration for editing
     chmod o+w config/config.inc.php     # give it world writable permissions
     

     On other platforms, simply create the folder and ensure that your web server has read and write access to it. FAQ 1.26 can help with this.

     Next, open scripts/setup.php in your browser. Note that changes are not saved to disk until explicitly choose Save from the Configuration area of the screen. Normally the script saves the new config.inc.php to the config/ directory, but if the webserver does not have the proper permissions you may see the error “Cannot load or save configuration.” Ensure that the config/ directory exists and has the proper permissions – or use the Download link to save the config file locally and upload (via FTP or some similar means) to the proper location.

     Once the file has been saved, it must be moved out of the config/ directory and the permissions must be reset, again as a security measure:

     mv config/config.inc.php .         # move file to current directory
     chmod o-rw config.inc.php          # remove world read and write permissions
     

     Now the file is ready to be used. You can choose to review or edit the file with your favorite editor, if you prefer to set some advanced options which the setup script does not provide.

5. If you are using the auth_type “config”, it is suggested that you protect the phpMyAdmin installation directory because using config does not require a user to enter a password to access the phpMyAdmin installation. Use of an alternate authentication method is recommended, for example with HTTP–AUTH in a .htaccess file or switch to using auth_type cookie or http. See the multi–user sub–section of this FAQ for additional information, especially FAQ 4.4.
6. Open the main phpMyAdmin directory in your browser. phpMyAdmin should now display a welcome screen and your databases, or a login dialog if using HTTP or cookie authentication mode.
7. You should deny access to the ./libraries subfolder in your webserver configuration. For Apache you can use supplied .htaccess file in that folder, for other webservers, you should configure this yourself. Such configuration prevents from possible path exposure and cross side scripting vulnerabilities that might happen to be found in that code.
