-`NITRO_SSL_CERT` and `NITRO_SSL_KEY` - if both are present, this will launch the server in HTTPS mode. In the vast majority of cases, this should not be used other than for testing, and the Nitro server should be run behind a reverse proxy like nginx or Cloudflare which terminates SSL.
### Using PM2
To use `pm2`, use an `ecosystem.config.js`:
```js [ecosystem.config.js]
module.exports = {
apps: [
{
name: 'NuxtAppName',
exec_mode: 'cluster',
instances: 'max',
script: './.output/server/index.mjs'
}
]
}
```
