Reset password and give admin rights to redmine account

First of all run mysql:

mysql --user=root --password=your_password

You can find your connection parameters in {your redmine folder}/htdocs/config/database

If credentials are correct you will see hello message from MySql console:

Now you need to reveal all databases on current mysql server, run this command:

SHOW DATABASES;

You will see something like this:

We need to select active database, choose something with word “redmine” in name, for me it “bitnami_redmine” and run command:

use your_database_name;

In my case it looked like this:

To reveal current users information you can use this command:

select * from users;

Then we can reset password and any other property for any user in this table. Example with admin user:

update users set hashed_password = '353e8061f2befecb6818ba0c034c632fb0bcae1b', salt ='' where login = 'admin';

Or you can reset password for regular user and make give it admin rights at the same time:

update users set hashed_password = '353e8061f2befecb6818ba0c034c632fb0bcae1b', salt ='', admin = 1 where login = 'user';

Now we can login to redmine with admin rights using password: password
for account you used in previous step.
