Hi, the mysql issue should be fixed with this commit.

About the mkdir issue, can you list the content of /srv/modoboa please ?

fpiccinali commented 8 years ago

hello tonioo, i confirm that mysql is fixed.

But i still have error in both mode (postgres or mysql):

  File "/root/modoboa-installer/modoboa_installer/utils.py", line 82, in mkdir

@tonioo : how can i contribute to this project. I have added some small comments in installer.cfg and i would like to submit a pull request.

i made a local branch, commit my changes and when i want to push ...

git push

tonioo commented 8 years ago

Can you try to run the installer using the --debug option please? It looks like the deployment step fails for some reason...

To contribute, you can't push directly to this repository since you're not a team member. You need to do it the Github way:

Fork this repository (click on the button)
Commit your changes on your copy
Make a "pull request"

about :

could not change directory to "/root/modoboa-installer": Permission denied

i tried with modoboa_installer in a public folder (/tmp) and the message disapear. It remains the other errors

tonioo commented 8 years ago

The installer needs root privileges to run. How did you run the installer ? Using sudo or as root ?

fpiccinali commented 8 years ago

as root

fpiccinali commented 8 years ago

si tu veux je suis dispo pour faire une séquence de test à deux par skype ou au tél. ça risque d'être pénible a trouver ce genre de problème de droits.

tonioo commented 8 years ago

Sure, skype would be fine. Do you know my private email ?

tonioo commented 8 years ago

Can I close this issue ?

fpiccinali commented 8 years ago

no there is some new issues.

I have made test from scratch with an ubuntu-server 14.04 LTS The first one with the default parameter -i.e postgres - and the second with mysql.

With postgres it seems ok, i can connect to modoboa. With mysql, when i try a login i am redirected to https://myserver/admin/domains/ witch displays:

Sorry
An internal error occured.

I do not know where are logs file in order to help analyze.

During the process of installation i notice those errors|warnings :

About clamav, i am going to write a tuto in README.rst or maybe you could add a call to "freshclam" in the installer ?

tonioo commented 8 years ago

Indeed, there is a permission issue with MySQL... Maybe the way I create users and assign privileges is wrong. I'll try to reproduce it asap. About freshclam, what do you want to do ? Because I already download cvd files during the process.

fpiccinali commented 8 years ago

freshclam /etc/init.d/clamav-daemon restart

tonioo commented 8 years ago

The permission issue should be fixed now. I already run freshclam. https://github.com/modoboa/modoboa-installer/blob/master/modoboa_installer/scripts/clamav.py#L23

fpiccinali commented 8 years ago

Did you push your changes ? Error are still there :

i am skypable today if you need.

tonioo commented 8 years ago

I don't understand the clamav issue, the code has not changed recently and I can't reproduce this issue...

For the internal error, try to set DEBUG to True inside settings.py, you should see a complete stack trace.

I've fixed the postfix issue with my previous commit.

The amavis error is "normal" because the installer tries to create tables which already exist. This is a just a warning...

fpiccinali commented 8 years ago

ça marche !

J'ai essayé DEBUG = True dans settings.py mais je n'ai pas eu de stacktrace.

J'ai refait une installation from scratch et j'ai juste changé "engine = mysql" dans installer.cfg ---> succès

Ensuite, je réinstalle un OS, et je recommence la manip mais en configurant les mots de passe mysql par autre chose dans installer.cfg. --> succès

PS: saurais tu me recommander un outil pour voir les tables MYSQL. Habituellement j'utilise phpmyadmin, mais dans cette configuration j'aimerai me passer de la totale APACHE/PHP. Est ce qu'en python il y a un équivalent ?

You can close this issue.

tonioo commented 8 years ago

Unfortunately, I don't know such a tool. I generally only use the command line tool...

mawesome4ever commented 4 months ago

I'm running into this exact same issue installing on Ubuntu 24.04. Here is the debug info when installing. Btw, this is on a fresh Ubuntu server.
