Create Monkshu Service on Linux CentOS Ubuntu

1. If needed, permit node to bind to lower ports using this command - sudo setcap 'cap_net_bind_service=+ep' `which node` . Monkshu runs as a regular OS process, not a privileged process and never as root.

2. Download crashguard using git clone https://github.com/TekMonksGitHub/crashguard.git

3. Copy [monkshu_path]/crashguard.process.json to [crashguard_path]/conf/process.json. E.g. cp ~myapp/monkshu/crashguard.process.json ~myapp/crashguard/conf/process.json.

4. Edit the file [crashguard_path]/conf/process.json and fix the paths inside the file to match your setup.

5. Test the configuration works by running crashguard, e.g. - node ~/crashguard/crashguard.js. If this works both the backend and frontend servers should be started and the console will display the appropriate messages.

6. If the test above works, kill crashguard using Ctrl+C or the kill command. We will now setup crashguard to start as a system service.

7. Copy the file [monkshu_path]/monkshu.service to /usr/lib/systemd/system. E.g. cp ~myapp/monkshu/monkshu.service /usr/lib/systemd/system.

8. Edit this file using this command vi /usr/lib/systemd/system/monkshu.service and fix these lines to match the Monkshu user and path on your system

User=monkshu
ExecStart=/usr/bin/env node /home/monkshu/crashguard/crashguard.js

9. Enable the service using systemctl enable monkshu.

10. Start the service using systemctl start monkshu.

11. Run this command to ensure Monkshu is running cleanly - systemctl status monkshu. The output should show active (running) as below.
