2.10.5. Install and update n8n

n8n — open-source platform for automating various processes and interacting with external services.

See CMS auto-install.

1. In the "Linux configuration" section, set Node.js 20 or higher.
2. Connect to the hosting via SSH.
3. Go to the site directory:

   cd ~/example.com/www

4. Install n8n:

   npm install n8n

5. Install SSL certificate (if not installed).
6. In the "Site settings" section, set the following settings:
   • "Web server" — "Node.js".
   • "Node.js version" — 20 or higher.
   • "Traffic proxying" — "By IP address".
7. Create environment for launching n8n:
   1. In the site root directory, create the .env file with the following environment parameters:

      N8N_LISTEN_ADDRESS=123.45.67.89
      N8N_PORT=3000
      N8N_HOST=example.com
      WEBHOOK_URL=https://example.com/
      N8N_PROXY_HOPS=1
      N8N_USER_FOLDER=
      
      N8N_RUNNERS_ENABLED=true
      N8N_RUNNERS_MODE=internal
      N8N_RUNNERS_BROKER_LISTEN_ADDRESS=123.45.67.89
      N8N_RUNNERS_BROKER_PORT=3001
      
      N8N_SMTP_HOST=mail.adm.tools
      N8N_SMTP_PORT=465
      N8N_SMTP_USER=admin@example.com
      N8N_SMTP_PASS=password
      N8N_SMTP_SENDER=admin@example.com
      
      DB_SQLITE_POOL_SIZE=2
      N8N_BLOCK_ENV_ACCESS_IN_NODE=true
      N8N_GIT_NODE_DISABLE_BARE_REPOS=true

      In the file, use your own data:

      • Launch parameters:
        • N8N_LISTEN_ADDRESS — IP address from the "Node.js settings" section.
        • N8N_PORT — port from the "Node.js settings" section.
        • N8N_HOST — domain of your site.
        • WEBHOOK_URL — URL of your site.
      • Data storage:
        • N8N_USER_FOLDER — path for placing the .n8n directory, which stores user data such as databases and encryption keys (empty value = site root directory, which is useful for backups).
      • Runner settings:
        • N8N_RUNNERS_BROKER_LISTEN_ADDRESS — IP address from the "Node.js settings" section.
      • Sending mail:
        • N8N_SMTP_USER — mailbox name.
        • N8N_SMTP_PASS — mailbox password.
        • N8N_SMTP_SENDER — mailbox name.
   2. In site root directory, create the package.json file with the following content:

      {
        "name": "n8n-app",
        "version": "1.0.0",
        "scripts": {
          "start": "./node_modules/n8n/bin/n8n"
        },
        "dependencies": {
          "n8n": "^2.4.7"
        }
      }

8. In the runner code, replace 127.0.0.1 with the variable so that the runner uses the correct IP address during operation:

   sed -i 's/127\.0\.0\.1/${this.runnerConfig.listenAddress}/g' ./node_modules/n8n/dist/task-runners/task-runner-process-base.js

9. In the "Node.js settings" section, restart the app.
10. Open your site in a browser and register as an administrator.
11. Check the n8n operation.

1. Connect to the hosting via SSH.
2. Go to the site directory:

   cd ~/example.com/www

3. Update n8n:

   npm update n8n

4. In the runner code, replace 127.0.0.1 with the variable so that the runner uses the correct IP address during operation:

   sed -i 's/127\.0\.0\.1/${this.runnerConfig.listenAddress}/g' ./node_modules/n8n/dist/task-runners/task-runner-process-base.js

5. In the "Node.js settings" section, restart the app.
