First you need to [install PredictionIO <%= data.versions.pio %>](/install) (if
you haven't done it).

Let's say you have installed PredictionIO at `/home/yourname/PredictionIO/`.
For convenience, add PredictionIO's binary command path to your `PATH`, i.e.
`/home/yourname/PredictionIO/bin`:

```
$ PATH=$PATH:/home/yourname/PredictionIO/bin; export PATH
```

NOTE: If you launched **PredictionIO AWS instance**, the path is located at
`/opt/PredictionIO/bin`.

Once you have completed the installation process, please make sure all the
components (PredictionIO Event Server, Elasticsearch, and HBase) are up and
running.

NOTE: If you launched **PredictionIO AWS instance**, you can skip `pio-start-all`. All components should have been started automatically.

If you are using PostgreSQL or MySQL, run the following to start PredictionIO
Event Server:

```
$ pio eventserver &
```

If instead you are running HBase and Elasticsearch, run the following to start
all PredictionIO Event Server, HBase, and Elasticsearch:

```
$ pio-start-all
```

You can check the status by running:

```
$ pio status
```

If everything is OK, you should see the following outputs:

```
...

(sleeping 5 seconds for all messages to show up...)
Your system is all ready to go.
```

PredictionIO](/resources/faq/#using-predictionio).
