Common Problems
|
|
---------------
|
|
|
|
In my startup logs I see *'Aborting... Lemur cannot locate db encryption key, is LEMUR_ENCRYPTION_KEYS set?'*
|
|
You likely have not correctly configured **LEMUR_ENCRYPTION_KEYS**. See
|
|
:doc:`administration` for more information.
|
|
|
|
|
|
I am seeing Lemur's javascript load in my browser but not the CSS.
|
|
Ensure that you are placing *include mime.types;* to your Nginx static file location. See
|
|
:doc:`production/index` for example configurations.
|
|
|
|
|
|
After installing Lemur I am unable to login
|
|
Ensure that you are trying to login with the credentials you entered during `lemur init`. These are separate
|
|
from the postgres database credentials.
|
|
|
|
|
|
Running 'lemur db upgrade' seems stuck.
|
|
Most likely, the upgrade is stuck because an existing query on the database is holding onto a lock that the
|
|
migration needs.
|
|
|
|
To resolve, login to your lemur database and run:
|
|
|
|
SELECT * FROM pg_locks l INNER JOIN pg_stat_activity s ON (l.pid = s.pid) WHERE waiting AND NOT granted;
|
|
|
|
This will give you a list of queries that are currently waiting to be executed. From there attempt to idenity the PID
|
|
of the query blocking the migration. Once found execute:
|
|
|
|
select pg_terminate_backend(<blocking-pid>);
|
|
|
|

How do I
|
|
--------
|
|
|
|
... script the Lemur installation to bootstrap things like roles and users?
|
|
Lemur is a simple Flask (Python) application that runs using a utility
|
|
runner. A script that creates a project and default user might look something
|
|
like this:
|
|
|
|
.. code-block:: python
|
|
|
|
# Bootstrap the Flask environment
|
|
from flask import current_app
|
|
|
|
from lemur.users.service import create as create_user
|
|
from lemur.roles.service import create as create_role
|
|
from lemur.accounts.service import create as create_account
|
|
|
|
role = create_role('aRole', 'this is a new role')
|
|
create_user('admin', 'password', 'lemur@nobody', True, [role]
|
