Distribution: Centos
Codename: Centos 7
Arch: 64 Bits
Database: PostgreSQL

problems that occured during installation which i had to fix: (probably not related to this issue, just to point it out)

Instalator continues even when LetsEncrypt cert is not obtained (got cert manually, SSL now valid and working)
Nginx config was broken by default (Nginx issue, not your, happened even when i installed nginx before Modoboa - had to add server_names_hash_bucket_size 64; to main config, otherwise nginx wouldnt start

finally after all, nginx is now running, but when trying to access admin panel, i just get 502 error...

From nginx error log:

2018/04/07 19:19:22 [error] 22551#0: *1 upstream prematurely closed connection while reading response header from upstream$

tried some solutions, but i dont know anymore, tried to reinstall too :'(

Database: PostgreSQL

I had to run LetsEncrypt manually also. Got it working with nginx

looks like something is running in back-end, cuz few "modoboa" processes go 100% CPU every minute

@wUFr Either try a fresh install (on a clean system) or remove the virtualenv before restarting the installer:

rm -r /srv/modoboa/env
rm -r /srv/modoboa/.cache/pip

that fixed it, please consider adding this tip on website too (:

I have the same problem. Any Idea ? And also this bug doesnt seem new. I think modoboa isnt production ready.

tonioo commented 5 years ago

I fixed a bug recently about this: https://github.com/modoboa/modoboa-installer/commit/3bcd8c172ff1d90141fdda3d05f1b32c5a03c9d9.

AncalagonTheBlack commented 5 years ago

I see. But this bug also happens on debian 9. Should i open a new issue about that ?

tonioo commented 5 years ago

@AncalagonTheBlack Yes, with a full trace using the --debug option please.

Hi there! I encounter is about some SE Linux policies related to nginx.

You can check your auditlogs, identify which policies are restricting the port to be accessed (or just use grep to check nginx blocks), identify your auditlog message id and use audit2allow for keeping instructions to be applied by semodule.

sudo grep avc /var/log/audit/audit.log
sudo grep ${message_id_on_auditlog} /var/log/audit/audit.log | sudo audit2allow -M nginx_allow_t
sudo semodule -i nginx_allow_t.pp

modoboa / modoboa-installer

Web panel gives 502 bad gateway after install #201
