problem while Ralph 3.0 install

[ziompaul]

I have a problem while Ralph 3.0 Initialization.

When I try to type commands: _ralph migrate, ralph sitetree_resyncapps, ralph createsuperuser, it edns with an error:

PermissionError: [Errno 13] Permission denied: '/opt/ralph/ralph-core/lib/python3.4/site-packages/atomic/pycache/_cffi__xaa896a6dxf914a2ce.c'

What is the problem?

Regards

Probably it's problem with metrology package. @romcheg can you confirm that?

[romcheg]

@ar4s the only way it could be related to metrology is that metrology or one of its dependencies use FFI and so require libffi to be installed. Since metrology was integrated into Ralph a while ago, I am not sure it is a root cause of the issue. Anyway, @ziompaul could you please verify libffi is installed.

[ziompaul]

Yes, libffi is installed.

[vi4m]

Why we ship metrology in open source edition? It should be opt-in @romcheg

[ziompaul]

Always is thesame error, whatever i put with the ralph commad, the error is thesame. Full:

[mkurek]

@ziompaul what OS and in what architecture are you using to install ralph?

[ziompaul]

It is Ubuntu Server 14.04.5 LTS - ubuntu-14.04.5-server-amd64.iso.

[vi4m]

/opt/ralph/ralph-core/ is not writable for users. If you run it as root it will probably works fine. It seems cffi tries to write to some files in this location.

[vi4m]

We should think about

a) maintain proper permissions during the installation b) decide if we should run as root or normal user. Most of the people still uses root account.

[ziompaul]

OK, there were some difficulties, because by default the root account was not configured during the Ubuntu installation (not known password), login to root by ssh/winscp was blocked, but after I beat the problems, I have installed the Ralph again on root, and then the inicialization went good.

[ziompaul]

Is there a possibility to run the ralphserver in background?

[mkurek]

If you want to run it temporarily, use screen or something similar. If you want it to be persistent, try supervisord or nginx (and try with gunicorn instead of runserver - runserver should be used only to development: http://docs.gunicorn.org/en/stable/deploy.html)
