Docker 없이 Discourse 배포하기

공식 설치 가이드에 따라 Discourse를 배포하는 것이 더 편리하고 안전하지만, 컨테이너를 더 깊이 파고들어 Docker 없이 Linux에서 어떻게 배포할 수 있는지 살펴보고 싶습니다. 이 단계들을 공유하는 것은 단지 참고용입니다. 해당 내용을 적용하고 사용하는 것은 전적으로 본인의 책임 하에 이루어져야 합니다.

컨테이너에서 Discourse가 실행되는 방식을 자세히 살펴보기

./launcher start-cmd webonly의 출력을 살펴봅니다:

true run --shm-size=512m --link data:data -d --restart=always -e LANG=en_US.UTF-8 -e RAILS_ENV=production … --name webonly -t -v /var/discourse/shared/webonly:/shared … local_discourse/webonly /sbin/boot

이후 /sbin/boot/etc/service/unicorn/run을 살펴보면 Discourse를 시작하는 핵심 명령을 알 수 있습니다:

LD_PRELOAD=$RUBY_ALLOCATOR HOME=/home/discourse USER=discourse exec thpoff chpst -u discourse:www-data -U discourse:www-data bundle exec config/unicorn_launcher -E production -c config/unicorn.conf.rb

시스템 준비

참고로 저는 Ubuntu 24.04와 zsh를 사용합니다.

PG의 공식 설치 가이드를 따라 PostgreSQL Apt Repository에서 postgres를 설치합니다. 작성 시점의 공식 설치에서는 15버전을 사용하지만, 저는 18버전을 설치했으며 잘 작동합니다.

redis(작성 시점의 공식 설치에서는 7.0을 사용하지만 8.2), nginx를 설치하고 전용 사용자 discourse를 생성합니다:

apt install nginx libnginx-mod-http-brotli-static redis zsh zsh-autosuggestions zsh-syntax-highlighting
systemctl enable --now postgresql redis nginx
useradd -m -s /bin/zsh discourse

ImageMagick 7을 설치합니다(저는 IMEI를 사용)하고 버전을 확인합니다. 제 버전은 다음과 같습니다:

magick --version
Version: ImageMagick 7.1.2-3 Q16-HDRI

이후 사용자를 변경(su - discourse)하고 pnpm, rvm을 설치합니다.

curl -fsSL https://get.pnpm.io/install.sh | zsh -
curl -sSL https://get.rvm.io | bash

그리고 다음 설정을 .zshrc에 맞게 수정하여 추가합니다.

/home/discourse/.zshrc

# pnpm
export PNPM_HOME="/home/discourse/.local/share/pnpm"
case ":$PATH:" in
  *":$PNPM_HOME:"*) ;;
  *) export PATH="$PNPM_HOME:$PATH" ;;
esac
# pnpm end
alias npm='pnpm'
alias npx='pnpx'

# Add RVM to PATH for scripting. Make sure this is the last PATH variable change.
export PATH="$PATH:$HOME/.rvm/bin"

export DISCOURSE_MAX_DATA_EXPLORER_API_REQ_MODE=none

export DISCOURSE_MAX_REQS_PER_IP_EXCEPTIONS="127.0.0.1 ::1"
cd /var/www/discourse

.zshrc가 적용되도록 discourse 사용자로 로그아웃했다가 다시 로그인합니다.

node와 ruby를 설치합니다:

pnpm env use --global latest # 작성 시점에는 node 24.9가 설치됩니다. 공식 설치에서는 22를 사용합니다.
rvm get master
rvm install 3.4 # 작성 시점에는 ruby 3.4.6이 설치됩니다. 공식 설치에서는 3.3을 사용합니다.
rvm use 3.4 --default

데이터베이스 준비 (및 백업 복원)

sudo -u postgres createuser -s discourse                                                   
sudo -u postgres createdb discourse 

$sudo -u postgres psql discourse
psql>
ALTER USER discourse WITH PASSWORD 'xxx';
CREATE EXTENSION hstore;CREATE EXTENSION pg_trgm;
CREATE EXTENSION plpgsql;
CREATE EXTENSION unaccent;
CREATE EXTENSION vector;
# 백업에서 추출한 데이터베이스를 복원하려면:
$ gunzip < dump.sql.gz | psql discourse

백업을 복원하려면 public 폴더와 plugins 폴더도 복사해야 합니다.

Discourse 설치

discourse_docker/templates/web.template.yml at 20e33fbfd98d3b8d9c57f7a111beff8aa51a5b98 · discourse/discourse_docker · GitHub 를 참고했습니다.

root 사용자로:

cd /var/www/
git clone https://github.com/discourse/discourse
mkdir -p /var/www/discourse/public
chown -R discourse:discourse /var/www/discourse/     
chown -R discourse:www-data /var/www/discourse/public

config/discourse.conf를 구성합니다:

bundle / pnpm 설치, db 마이그레이션, 자산 프리컴파일 등을 수행합니다. 이것이 또한 Discourse와 플러그인을 업그레이드하는 방법이기도 합니다.

discourse 사용자로:

cd /var/www/discourse
git stash
git pull
git checkout tests-passed 
cd plugins

do
    echo $plugin; cd ${plugin}; git pull; cd ..
done
cd ../

bundle install --jobs $(($(nproc) - 1))
pnpm i
bundle exec rake db:migrate
bundle exec rake themes:update
bundle exec rake assets:precompile

unicorn을 사용하고자 하지 않습니다. Heroku는 Unicorn 대신 Puma 웹 서버 사용을 권장합니다. config/unicorn.conf.rb를 참고하여 작성한 제 config/puma.rb는 다음과 같습니다:

Discourse를 실행하려면 puma -C config/puma.rb를 실행합니다.

systemd를 사용하면 부팅 시 실행하고 실패 시 재시작할 수 있습니다. 서비스 파일은 다음과 같습니다:

이제 puma 서버가 127.0.0.1:3000에서 리스닝합니다. Docker에서 가져온 nginx 설정 파일을 수정합니다:

이제 example.com:443에서 Discourse에 액세스할 수 있습니다.

유지보수

rails 콘솔에 액세스하려면 /var/www/discourse에서 discourse 사용자로 rails c를 실행하면 됩니다. 공식 문서에서 찾을 수 있는 discourse 명령은 기본적으로 bundle exec script/discourse입니다.

Discourse를 업그레이드하려면 #upgrade-cmd를 참고한 후 puma restart 또는 puma phased-restart 중 하나를 사용하여 puma를 재시작합니다. 두 명령의 차이에 대해서는 puma/docs/restart.md at main · puma/puma · GitHub 를 참고하십시오.

Should this be moved to #community-wiki:sysadmins, perhaps?

Hi. Thanks for sharing.

I am writing a script for this to installed on debian 12 in a lxc container. It is almost finished and works fine. I will publish when it is ready.

I’ve managed to display the first page for the admin registration. But the confirmation email is sent to discourse@myhostname, and to myhostname as smtp_server, so it is absurd. The varaibles in .bashrc (or .zshrc), neither in the discourse.conf are taken in account for sending the email. The email_adress for the developper is correct but all other parameters are wrong and I could not change them. Would you have any idea to know how to achieve this?

According to code

SMTP should be configured in config/discourse.conf.
For me, I have these lines in it:

smtp_user_name = '...com'
smtp_address = '...com'
smtp_port = '587'
smtp_password = '...'
smtp_domain = '...com'
notification_email = 'noreply@....com'

Have you checked logs? For this custom install, the log is in production.log, production.log, puma.stdout.log under log dir.

Thanks a lot for your response.

I have already these settings in config/discourse.conf. I did exactly what you wrote except with zsh.
My logs don’t speak about smtp, and the only from (production.log) it is

Thanks. I’ve forgot to say that it is behind haproxy for multiple servers.

  1. I get “mix content” from the console of the browser. What can i change in the nginx file?
  2. I get this log about magick at boot of puma command. It is although installed at begin.

I have read it can be a cause for not showing pages.

Do you force ssl in Discourse settings?

Can you run magick --version as discourse user? For me the output is:

Yup, exactly what I was thinking.

I’ve found a lot of un-met dependencies while “manually” installing. I’m writing an ansible to be able to deploy discourse on multiple environments.

My systems are almalinux/redhat but I’ll share what I’ve found when I consider it almost done.

In haproxy.cfg 443 is with crt, so encrypted, redirected to the container through 8080:

backend BACKEND_XXX
option forwardfor
http-request set-header X-Forwarded-Port %[dst_port]
http-request add-header X-Forwarded-Proto https if { ssl_fc }
server xxx 192.168.1.48:8080 weight 1 #adding “check ssl verify none” if ssl on nginx discourse

  1. In nginx/…/discourse.conf, i copied the version of this post and modified the port and the servername and the certificate files location,
    => PB1: got mixed contents and logs with same problem of magick
    => PB2: on “/confirm-email” page i get an error "site not found " of browser.

  2. Then I modified the file removing the ssl on port and commented all lines with “$thescheme”, to only encrypt in haproxy.
    => 502 error on first page, same logs with magick

  3. Then I installed magick from source (7.1.2.3), added binary folder to PATH in .bashrc for root and for discourse users. It did not work with via apt install (no effect like this one).
    => 502 error went away, still mixed content and "site not found " of browser.
    => logs still magick not found but different.

Conclusion:
How to make magick foundable by puma?
How to disable ssl in nginx because of haproxy?

I’ve managed to get it work like described in my first post, but here without ssl on nginx by copying the nginx.config.sample with just changing the hostname and port.
So both with ssl or without on nginx, I get the first page for admin registration until resend email page, but BOTH:

  1. display “mixed content” (for images files for instance),
  2. other pages than admin registration shows “Ooops…”
  3. no confirmation emails are sent
  4. magick is still not found

Somewhere in one of your posts you mention container.

Are you using containers for any of the involved parts?

Today i wanna finalise my deployment in the preprod environment and maybe I’ll have more info to share.

Same as you :unamused_face:

  • Not sending confirmation email (I’m using mailtrap, I’m sure it works).
  • Created admin user with rake
  • Oops on /after that…
  • Also seen magick issue and magick is installed (I’m pretty sure there’s some rubygem missing…)

I’m deploying it using docker and then compare. I hate docker :expressionless_face: but I’ll wasting a lot of precious time…

I barely know Docker (if any at all!) and I didn’t have to know it to run a Discourse forum in production. Just by following the supported instructions, it’ll get you what you need.

Yup, I believe you. But i need to know what I’m deploying and how it works.

It’s the best way to find and solve problems :squinting_face_with_tongue:

Because you’ll have problems, always maybe not now, but I’ll sure the future you will find someone.

Anyway, as i won’t get support using alternative install method, I’ll follow the official instructions and try to help others :winking_face_with_tongue:

I also spent a lot of time on these issues.
About Docker, look at this issue on Docker (a mistake or a backdoor ?..), corrected at the moment: https://youtu.be/dTqxNc1MVLE
That is one of my reasons why I would not use Docker.
I am using lxd (lxc) containers, and i feel fine with it. I am going to install Docker on an lxc container at first, and export the database later when the install without Docker on an lxc is possible.

Well I am not forcing Discourse to ssl because I want to let my haproxy do it because haproxy passtrough does not work with http protocol to redirect GET requests, and i am handling multiple websites so i need http protocol in haproxy, so it requires ssl handling on haproxy side. I would like to avoid double ssl gateway.
So haproxy (on one lxc) listens 443: redirect to 8080 (no ssl) to my discourse container (lxc).
Curious is that the nginx-config-sample given in the discourse folder is configured without ssl and port 80, so it should work well, but i get the above mentioned problems.

You need to do that to tell discourse to send only https links. It’s not changing the redirects, but the need for them.

You need to turn on the force https setting.

HTTPS: Yes, but please tell me how to turn it on?

A GREAT NEWS! I HAVE RESOLVED THE PROBLEMS!!! The source was magick programm. After correct magick install from source version 7 (do not install imagemagick with apt, it is version 6), my discourse website displays all pages correct! Emails, admin registration, etc. work! After “mixed content” problem resolved, i will publish my script for installation on a lxd-lxc container (Debian 12) behind haproxy.on another lxd-lxc container.
