| As part of running a service in production, you want to make sure that the service stays up so it's important to use something like systemd to manage this. | As part of running a service in production, you want to make sure that the service stays up so it's important to use something like systemd to manage this. | ||
| + | |||
| + | Here's an example of a very simple systemd service file: | ||
| + | |||
| + | <code> | ||
| + | [Unit] | ||
| + | Description=Example app | ||
| + | After=network.target | ||
| + | |||
| + | [Service] | ||
| + | Type=simple | ||
| + | User=scel | ||
| + | WorkingDirectory=/home/example-user/example-app | ||
| + | ExecStart=/home/example-user/example-app/run.sh --some-flag | ||
| + | Restart=always | ||
| + | |||
| + | [Install] | ||
| + | WantedBy=multi-user.target | ||
| + | </code> | ||
| + | |||
| + | This could be installed in `/etc/systemd/system/example-app.service` | ||
| + | |||
| + | After installing it, you can reload the config: | ||
| + | |||
| + | <code> | ||
| + | systemctl daemon-reload | ||
| + | systemctl start example-app.service | ||
| + | </code> | ||
