Drupal Uninstall of CiviCRM?

[jschrab]

I have a need to uninstall the CiviCRM modules and do not have a need to preserve the CiviCRM tables.  After disabling the module in Drupal, is it as simple as deleting the module and dropping the related tables?

[Donald Lobo]

yes.

if running the latest 2.2 beta (beta3 or beta4), uninstalling the module will take care of deleting the tables from the database

hi jschrab

also you need to remove civicrm.settings.php from [your Drupal root directory]/sites/default
If not removed, this file will not allow you to reinstall CiviCRM, though you have uninstalled.

I'm back on 2.1 and would like to start fresh.  It's no problem for me to disable/delete/drop files/db's.  So I think I got it - thanks!

Problem: Drupal, CiviCRM not removed from Modules list after uninstall
System: Drupal 7.26, CiviCRM 4.2, MySQL 5.5.32
Situation: Site migration, needing clean CiviCRM DB.
Desire: Dump CiviCRM DB, Update CiviCRM to current.
Process:

• Made back-up
  
• Deleted module from sites/all/modules/
• Dumped CiviCRM DB.
• Attempted to install CiviCRM 4.7 - Failure
• Realised made a big mistake! 

Problem: CiviCRM still appears in modules list, and installing a new module version does not work.
Things I realised: RTFM, do one process at a time, lock down the site so other admin don't do work at the same time!!

Attempted solutions:
1. reinstalling original 4.2 version, reinstalling backup CiviCRM database, activating 4.2, then deactivating, uninstalling and then deleting the file from /all/modules and removing civicrm.settings.php.
Result: fail, still appears in the modules list (after many cache flushes).

2. deleting module, deleting civicrm DB, deleting all instances of "civicrm" from the Drupal MySQL.
Result: fail, still appears in the modules list.

3. reinstalling original 4.2 version, reinstalling backup CiviCRM database, activating 4.2, then deactivating, uninstalling and then deleting the file from /all/modules and removing civicrm.settings.php. Then installing 4.4.3.
Result: "CiviCRM is already installed."

Stumped. Revert to backup?

I know my answer is a bit late... LOL... but I'm a newbie on the CiviCRM forum.... but I've been working on Drupal for like a decade... but as usual, we will always learn new things everyday.

I'm sure you've figured it out by now, but just in case... here's the "manual" version that I know how to do 

• When you "disable" a module inside Drupal, you have to then click on the "uninstall" tab and select the modules you want to uninstall.
• After that, you then have to go to your PHPAdmin for your Drupal database and find the "system" table ... click on it
• and then search for the modules you just disabled and uninstalled.
• once you find them, click the edit link and set the status from "1" to "0"
• Then you go to your "/sites/all/modules" folder and delete the modules you disabled

NOTE:  Always make backups of your entire site and database BEFORE doing any of these steps.

phpMyAdmin

To disable a module via phpMyAdmin you must login to phpMyAdmin. Then you must locate the database where Drupal is installed. Once you have done so look for the "system" table. Click and open it. Click to browse the table. Find the record for the module that is causing the problems and select the edit function. Set the status to "0" and save.
