CrowdRescue

Disaster response and relief management for volunteer teams

Prerequisites

You'll need Ruby and MySQL installed to be able to set CrowdRescue up locally.

Setup

  • Clone the repository and cd into the repository directory.
  • Install the required gems:
$ bundle install
$ cp config/settings.sample.yml config/settings.yml
  • Same for database config: copy and fill in your real username and password:
$ cp config/database.sample.yml config/database.yml
  • Run MySQL if it is not already running.

You can check if MySQL is running with

$ ps aux | grep mysql

On Linux, start MySQL with

$ sudo systemctl restart mysql

On Mac, use

$ mysqld
  • Set up the database:
$ rails db:create
$ rails db:schema:load
$ rails db:migrate
  • Run the server with
$ rails s

MySQL permissions setup

You may see an error about MySQL permissions. If you do, you need to set up your user's permissions within MySQL.

You'll want to log in to MySQL as root so you can make these changes. Make sure MySQL is running first. On MacOS, run:

$ sudo mysql

Enter your password (the one you normally use with sudo, not a MySQL related password).

On Linux, use:

$ mysql -u root -p

You'll now be in the MySQL console.

Change to the system database for MySQL.

mysql> use mysql;

List the MySQL users.

mysql> select user from user;
+---------------+
| user          |
+---------------+
| <your name>   |
| mysql.session |
| mysql.sys     |
| root          |
+---------------+

<your name> should be there; this should be the same name as the username listed in config/database.yml.

Look at the grants given to your user.

mysql> show grants for <your name>@localhost;

If you're having permission errors you probably do not have the needed grants.

Grant yourself all privileges on all tables on crowdrescue_dev. This will have been created when you ran the rails setup commands listed above.

mysql> GRANT ALL PRIVILEGES ON `crowdrescue_dev`.* TO '<your name>'@'localhost';

If you have other databases set up locally, like crowdrescue_test or crowdrescue_prod, grant yourself permission on those as well.

mysql> GRANT ALL PRIVILEGES ON `crowdrescue_test`.* TO '<your name>'@'localhost';
mysql> GRANT ALL PRIVILEGES ON `crowdrescue_prod`.* TO '<your name>'@'localhost';

Then tell MySQL to apply these changes with

Now make sure the privileges got added properly:

mysql> show grants for <your name>@localhost;
+--------------------------------------------------------------------------------------+
| Grants for <your name>@localhost                                                           |
+--------------------------------------------------------------------------------------+
| GRANT ALL PRIVILEGES ON `crowdrescue_dev`.* TO '<your name>'@'localhost' WITH GRANT OPTION |
| GRANT ALL PRIVILEGES ON `crowdrescue_test`.* TO '<your name>'@'localhost'                  |
+--------------------------------------------------------------------------------------+

You can now leave the MySQL console.

mysql> exit
Bye

Now try running SCOT again, you should have the permissions you need.
