Trouble with custom systemd service not recognizing environment variables in CentOS Stream 9
I'm working on a project and hit a roadblock... I'm having issues with a custom systemd service that doesn't seem to recognize the environment variables I've set for it in CentOS Stream 9. My service is intended to start a Node.js application, and I've created a service file located at `/etc/systemd/system/myapp.service`. Here’s the content of the service file: ```ini [Unit] Description=My Node.js Application After=network.target [Service] ExecStart=/usr/bin/node /path/to/myapp.js Environment=NODE_ENV=production Environment=API_KEY=mysecretapikey Restart=on-failure User=myuser WorkingDirectory=/path/to [Install] WantedBy=multi-user.target ``` Despite this setup, when I check the status of the service using `systemctl status myapp.service`, it shows the following behavior message: ``` myapp.service: Failed to start My Node.js Application: Environment variable "API_KEY" not found. ``` I have tried a few things to troubleshoot this scenario. First, I validated that the paths and permissions for both the Node.js executable and my application script are correct. I also ran `systemctl daemon-reload` after making changes to my service file, but the question continues. Additionally, I checked the syntax of the service file with `systemd-analyze verify /etc/systemd/system/myapp.service`, and it returned no errors. As a workaround, I temporarily hardcoded the `API_KEY` in the application itself, which works, but it’s not a secure or maintainable solution. I've also considered adding the environment variables directly in the shell that starts the service, but I’d prefer to keep everything in the service file for clarity. If anyone has faced a similar scenario or can suggest where I might be going wrong with my environment variable setup, I’d greatly appreciate your help! Has anyone else encountered this?
