mysql> USE iredadmin;
mysql> SOURCE /var/www/iredadmin/docs/samples/iredadmin.sql;
```

* Grant privileges to iredadmin user and set password for it. WARNING: Here we
  use 'secret_passwd' as password of iredadmin user, please replace it with
  your own password.

```
# mysql -uroot -p
mysql> GRANT SELECT,INSERT,UPDATE,DELETE ON iredadmin.* TO iredadmin@localhost IDENTIFIED BY 'secret_passwd';
mysql> FLUSH PRIVILEGES;
```

* Update settings.py with correct values. Please read `settings.py` for more
  information, it's self-documented.

## Access iRedAdmin

Open your web browser to access iRedAdmin: `https://your_server_ip_address/iredadmin/`

Make sure you use `HTTPS://` instead of `HTTP://`.

## Troubleshooting & Debug

If iRedAdmin doesn't work as expected, you can simplily set `DEBUG = True` in
`settings.py`, restart apache web server, use your favourite web browser to
access it again, create a new [forum](https://forum.iredmail.org/) topic and
paste error message in your forum topic.
