Cant install mailcow, error when running 'docker-compose up -d'

itzMiney

So, i just tried to install mailcow and everything went fine, until i tried the last step in the docs for installation, which is runnning docker-compose up -d:

I use NGiNX on a Debian 10 Server and here something i think might be related to the error: For some reason my own website that I’ve made myself as a little project (in /var/www/) does not only show up with www.example.com which it’s meant to do (server_name www.example.com; in sites-available/sites-enabled config), but when i got to mail.example.com it shows the same contents as www.example.com ? Also my own Website i mentioned only listens on port 80 on ipv4 and ipv6
Help pls i have no idea what to do …

Edit:
It also didn’t create something like a mailcow.conf file or similar in etc/nginx/sites-available, I don’t know if that’s important but gonna add that on here

Since you already have one webserver running you can’t run a second one on the same port which mailcow tries to do when you start the stack - hence the error message.

You may configure your local nginx as reverse proxy for the mailcow one. See more info on the docs:https://mailcow.github.io/mailcow-dockerized-docs/firststeps-rp/

MAGIC but there is no NGiNX config for mailcow in etc/nginx/sites-available, should i just make one?

diekuh

The reverse proxy configuration according to the docs is mandatory. 🙂

diekuh https://mailcow.github.io/mailcow-dockerized-docs/firststeps-rp/#nginx
how should i do this tho, there is no NGiNX config in /etc/nginx/sites-available for mailcow and i guess you have to put that in a config file somewhere there right? sorry but i have smol brain disease

MAGIC

Yes you need to create a site conf for this then.

itzMiney

MAGIC how should i call the site config? or does that not matter? also doesn’t a side config need more than that in it? again sorry for smol brain disease, try explaining it to someone who has less brain than a zombie pls

Or try explaining it in German if you can explain it easier that way, I’m a native German speaker anyways, just like to always go for English support because it’s better/faster on most services and my English is definitely better than my understanding of mail servers, or servers in general tbh .-.

ping

MAGIC

The file name of the config doesnt matter. It only need to contain the snipped which is in the docs.

itzMiney

MAGIC Yeah i tried exactly that but that didn’t work and I’m still getting the same error, that’s why I asked that
Doesn’t it need root and index specified in the site config? I tried with and without including root and index

itzMiney

I still haven’t resolved this issue :T
Right now I tried stopping NGiNX and then running docker-compose up -d which gets rid of the errors in the original post, but then NGiNX won’t start up again

I really don’t know what could possibly try to take up that port .-.

MAGIC

Well because you didnt really read the docs above?
Change the ports in mailcow.conf and create a site…

itzMiney

MAGIC which one, nginx conf or the one in the mailcow-dockerized folder? In any way, I tried doing that on both and it didn’t do a thing, out of frustration i also tried about a billion random ports and i get the same error with no matter which port, always says it’s already used by something else …

itzMiney

I’m really getting tired of this by now .-.
I kinda just wanna hop on a Discord call and share my screen with someone from support who actually knows what their doing (unlike me)

itzMiney#0727

If someone actually wants to do that then pls somewhere around early afternoon cuz I’m going to get some sleep now (CEST / GMT +1)

Still didn’t resolve this .-.

itzMiney

i still haven’t resolved this, my brains computing power is too low for this .-.

If someone from support has time I’d really like to solve this live in a Discord Call or something dunno
