# Core Linux - SSL Certificate Installation

This article covers adding an SSL certificate to modeller to host it over HTTPS.

## 1 - Obtain SSL Certificate

For testing you can create a self-singed SSL Certificate.

| **sudo** **openssl** **req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /nginx/server.key -out /nginx/server.crt** |
| --- |

It is recommended for production you obtain a signed SSL certificate from a registered issuing authority.

You should have a .crt and a .key file. Place these on the host machine's local storage. If you have paced them in a directory different than "/nginx", edit the volumes key in the **docker-compose.yml** file accordingly – replace these sections with your location.

---

## 2 - Setup the custom SSL configuration

The package folder comes with a file called **docker-compose-ssl.ym****l** - we will want to copy that file into a new file called **docker-compose-custom.ym****l** and then potentially edit this newly created file. If you already have a **docker-compose-custom.yml** file with some custom configuration elements, we will simply be editing that file instead.

```shell
cp docker-compose-ssl.yml docker-compose-custom.yml
```

By default, the **docker-compose-ssl.ym****l** file expects the certificate files obtained in step 1 to be available on the host machine at the following location:

**/nginx/server.crt** **/nginx/server.key**

If you are able to place the files there, you can simply proceed to the next step.

If you are unable to place the certificate files in the **/nginx** folder for some reason (e.g. permissions), you can edit the **docker-compose-custom****.yml** file to change the location or names of the certificate files under the **volumes** section of **nginx**

```yaml
nginx:
  image: nginx
  volumes:
    - ./nginx/nginx-https.conf:/etc/nginx/nginx.conf
    - [certificate-file-on-host]:/etc/nginx/server.crt
    - [key-file-on-host]:/etc/nginx/server.key
```

3 - Start (or restart) the Quality Modeller Services

Start the Quality Modeller services.

```shell
./run.sh
```

---

## 4 - Enable TLS v1.2 (Optional)

If you wish to enable TLS v1.2, you also need to edit the **package/nginx/nginx-https.conf** file to have the following values under the server block. Then restart the Quality Modeller services as described in step 4 above.

| **ssl_ciphers EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH;** **ssl_protocols TLSv1.2;** |
