supervisord process 'webvirtcloud' Exited too quickly

[pentacore]

OS: CentOS 7

After following the install instructions to install webvirtcloud and i try to start supervisord i get the following with supervisord status

[penta@pentavm ~]$ sudo supervisorctl status
novncd                           RUNNING   pid 28289, uptime 0:00:19
webvirtcloud                     FATAL     Exited too quickly (process log may have details)

And checking the process log gives the following:

[penta@pentavm ~]$ sudo supervisorctl tail webvirtcloud
supervisor: couldn't exec /srv/webvirtcloud/venv/bin/gunicorn: ENOENT
supervisor: child process was not spawned
supervisor: couldn't exec /srv/webvirtcloud/venv/bin/gunicorn: ENOENT
supervisor: child process was not spawned
supervisor: couldn't exec /srv/webvirtcloud/venv/bin/gunicorn: ENOENT
supervisor: child process was not spawned
supervisor: couldn't exec /srv/webvirtcloud/venv/bin/gunicorn: ENOENT
supervisor: child process was not spawned

No other errors as far as i can see, and I'm at my wits end

[catborise]

can you run this command and send us its output pls.

/srv/webvirtcloud/venv/bin/gunicorn webvirtcloud.wsgi:application -c /srv/webvirtcloud/gunicorn.conf.py

[pentacore]

[penta@pentavm ~]$ /srv/webvirtcloud/venv/bin/gunicorn webvirtcloud.wsgi:application -c /srv/webvirtcloud/gunicorn.conf.py
-bash: /srv/webvirtcloud/venv/bin/gunicorn: /var/lib/libvirt/boot/webvirtcloud/venv/bin/python: bad interpreter: No such file or directory

Guess a step or two is missing from the wiki

[catborise]

i am using main readme file for installation. this works, i never used wiki page for installation. i will check it.
https://github.com/retspen/webvirtcloud

did you install venv to this path "/var/lib/libvirt/boot/webvirtcloud/venv/bin/python"

if you know docker i would recommend it for installation. it so simple and works

[pentacore]

Yea i followed that to begin with, but got the same result, then i found the Wiki and tried using that.
No, Am i supposed to do that? didnt see any step to do that.

Ah, yea i know docker, just somehow missed that there was an image for it

[catborise]

no you should not. but something wrong with installation. and your setup is not same as told in readme. python seeks that path "/var/lib/libvirt/boot/webvirtcloud/venv/bin/python" but this should not happen. actually python should in that path "/srv/webvirtcloud/venv/bin/".

i think there are some virtualenv mishaps.

[pentacore]

Interesting, as far as i know i havent changed any paths. and most steps in the Wiki seems to be the same as in the readme

[pentacore]

Tried the Docker path but i cant build the image..

i tested again like below no problem on centos7 vm.

1. git clone https://github.com/retspen/webvirtcloud.git
2. cd webvirtcloud/
3. cp webvirtcloud/settings.py.template webvirtcloud/settings.py
4. Generate random number:

exit()

5. copy random number and paste it to settings.py as SECRET_KEY = ''

7. docker run -d -p 80:80 -p 6080:6080 retspen/webvirtcloud:0.1

it works as expected....

[pentacore]

Interesting that your Sending build context to Docker daemon size is ~120mb smaller than mine... i've got no idea whats happening here

EDIT: Nvm, probably the db taking up space

[catborise]

please try it with clean install...

• create a vm
• install a centos7 and update it
• install docker latest(https://docs.docker.com/install/linux/docker-ce/centos/)
• try it again.

probably your old config breaks something.
