# (optional) Test Ensembl browser

At this stage you may wish to start up a basic Ensembl mirror site using the local copy of the Ensembl core database(s) from the previous step. This will lack many of the additional features of a complete GenomeHubs site but provides a useful opportunity to check that the basic components are working before continuing with the instructions to import your own data.

## Edit `setup.ini`

Edit database settings:

* for the default setup, only `DB_SESSION_PASS` should need changing
* database hosts should match the name of your mysql container
* `DB_FALLBACK_HOST` is used to allow additional databases to be loaded from a remote host (in this case EnsemblGenomes) so not all databases need to be hosted locally

```
$ nano ~/genomehubs/v1/ensembl/conf/setup.ini
[DATABASE]
  DB_HOST = genomehubs-mysql
  DB_PORT = 3306
  DB_USER = anonymous
  DB_PASS =

  DB_FALLBACK_HOST = mysql-eg-publicsql.ebi.ac.uk
  DB_FALLBACK_PORT = 4157
  DB_FALLBACK_USER = anonymous
  DB_FALLBACK_PASS =

  DB_SESSION_HOST = genomehubs-mysql
  DB_SESSION_PORT = 3306
  DB_SESSION_USER = ensrw
  DB_SESSION_PASS = CHANGEME
```

Set database names to load:

* Assemblies will be listed on your Ensembl site homepage in the order they are added to `SPECIES_DBS`

## Start the EasyMirror container

Start the EasyMirror Docker container:

{% tabs %}
{% tab title="e93" %}

```
$ docker run -d \
             --name genomehubs-ensembl \
             -v ~/genomehubs/v1/ensembl/conf:/conf:ro \
             --network genomehubs-network \
             -p 8881:8080 \
             genomehubs/easy-mirror:19.05
```

{% endtab %}

{% tab title="e89" %}

```
$ docker run -d \
             --name genomehubs-ensembl \
             -v ~/genomehubs/v1/ensembl/conf:/conf:ro \
             --link genomehubs-mysql \
             -p 8081:8080 \
             genomehubs/easy-mirror:17.06
```

{% endtab %}

{% tab title="e85" %}

```
$ docker run -d \
             --name genomehubs-ensembl \
             -v ~/genomehubs/v1/ensembl/conf:/ensembl/conf:ro \
             --link genomehubs-mysql \
             -p 8081:8080 \
             genomehubs/easy-mirror:17.03

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://genomehubs.gitbook.io/genomehubs/quick-start/optional-ensembl.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
