# Linux SSL

If you would like to deploy and use ngSurvey on a Linux with a domain running under SSL you may use following script that will deploy ngSurvey using an ngInx SSL enabled reverse proxy :

## Ubuntu

you may use following shell script from your Ubuntu shell.

```
curl -o ngs-ubuntu-ssl-docker.sh https://ngsurvey.s3.eu-central-1.amazonaws.com/ngs-ubuntu-ssl-docker.sh 
sudo chmod +x ./ngs-ubuntu-ssl-docker.sh 
sudo ./ngs-ubuntu-ssl-docker.sh YOURDOMAIN.COM
```

This will generate a certificate for your domain and automatically configure ngSurvey under an secured HTTPS channel. 

{% hint style="danger" %}
Make sure that your domain is properly registered in your DNS with your host IP.    
{% endhint %}

## Custom database

By default the script above will use a mysql database. If you would like to use your own database you may modify the downloaded /srv/docker/ngsurveyee.ssl.mysql.yml file from the script above and use your own connectionstring to your database and then restart your ngsurvey setup using following command. 

```
sudo docker-compose -f /srv/docker/ngsurveyee.ssl.mysql.yml up -d
```
