Reference: https://github.com/logseq/logseq/tree/defclass/electron#set-up-development-environment

Prerequisites

1. Make sure all requirements listed at https://github.com/logseq/logseq/tree/defclass/electron#1-requirements are met

2. Install PostgreSQL create a DB called "logseq" and a user with SUPERUSER permissions

3. Install nginx & Certbot on your sever

4. Create GitHub application as discribed in https://docs.github.com/en/free-pro-team@latest/developers/apps/creating-a-github-app in the App set the Homepage URL to https://yourdomain.com - call back URL to https://yourdomain.com/auth/github Create a "client secret" & a "Private Key" for your app in app permissions set "Contents" access to "read and Write" Copy from your app

   • App ID
   • Client ID
   • Client Secret upload the pem file that was automatically downloaded when you created your app "Private Key" to your sever

Running LogSeq

1. Clone the logseq repo git clone https://github.com/logseq/logseq
2. Download backend.jar from https://github.com/logseq/logseq/releases/tag/0.0.1-100 and place it in ~/logsec/resources
3. In ~/logseq/src/main/frontend/config.cljs line 18 replace

(def website
  (if dev?
    "http://localhost:3000"
    (util/format "https://%s.com" app-name)))

by

(def website
  (if dev?
    "http://localhost:3000"
    "https://yourdomain.com"))

line 38 replace

(def github-app-name (if dev? GITHUB_APP_NAME "logseq"))

by

(def github-app-name (if dev? GITHUB_APP_NAME "yourappname"))

4. Set the envrionment variables

export GITHUB_REDIRECT_URI="https://yourdomain.com/auth/github"
export ENVIRONMENT="production"
export JWT_SECRET="somepass"
export COOKIE_SECRET="54676c2c5324279480a6ee1af0792588"
export GITHUB_APP2_NAME="yourappname"
export GITHUB_APP2_ID="appID"
export GITHUB_APP2_KEY="AppClientID"
export GITHUB_APP2_SECRET="AppClientSecret"
export GITHUB_APP_PEM="/path/to/github/pem/file/yourappname.2021-01-19.private-key.pem"
export LOG_PATH="/tmp/logseq"
export DATABASE_URL="postgres://localhost:5432/logseq"
export PG_USERNAME="username"
export PG_PASSWORD="password"
export WEBSITE_URL="https://yourdomain.com/"
export COOKIE_DOMAIN="yourdomain.com"

5. switch to ~/logsec and run yarn then, compile using yarn release
6. run from ~/logsec using java -Duser.timezone=UTC -jar ./static/logseq.jar

Publishing LogSeq

Now we need to "server" your self hosted logseq to the internet to do that

1. Create 2 DNS records domain.com & asset.domain.com & get a certificate for each using [[Certbot]]
2. configure Nginx to

• rewrite 'asset.logseq.com' to 'asset.domain.com';
• rewrite 'logseq.com' to 'domain.com';
• reverse proxy requests to 'domain.com' to 'logseq.jar' (http://localhost:3000)
• serve 'asset.domain.com' to /path/to/logseq/public/

A dummy copy of the ngix.conf file can be found here
