## Before you begin

* You have downloaded the installer file.
* You have created the Remote Engine in Talend Management Console.

## Procedure

1. Navigate to the download directory in your terminal.
2. Enter chmod +x <installer\_filename>.
   ### Example
   ```
   chmod +x Talend-RemoteEngine-V<2.9.0>-<173>-Linux-x64.run
   ```
3. Enter ./&lt;installer\_filename&gt; --mode unattended --installdir /opt/TalendRemoteEngine --region &lt;xxx&gt; --authkey &lt;PreAuthKey&gt;.
   ### Example
   ```
   ./Talend-RemoteEngine-V<2.9.0>-<173>-Linux-x64.run --mode unattended --installdir /opt/TalendRemoteEngine --region <us> --authkey <1a2b3c4d5e6f7g8h9i>
   ```
   * The region is reflected in your Talend Cloud URL.

     * If your URL is [http://us.cloud.talend.com](http://us.cloud.talend.com/), enter --region us.
     * If your URL is [http://ap.cloud.talend.com](http://ap.cloud.talend.com/), enter --region apac.
     * If your URL is [https://eu.cloud.talend.com](https://eu.cloud.talend.com/), enter --region emea.
     * If your URL is [https://au.cloud.talend.com](https://au.cloud.talend.com/), enter --region au.
     * If your URL is [https://us-west.cloud.talend.com](https://us-west.cloud.talend.com/), enter --region azuswest.

     &lt;PreAuthKey&gt; is the Remote Engine key generated when you created the engine in Talend Management Console.

   * To see a comprehensive list of available parameters for this command, run ./Talend-RemoteEngine-V&lt;2.9.0&gt;-&lt;173&gt;-Linux-x64.run --help.

     Any parameters that are not added to this command use their default values during the installation process.

     For example, Remote Engine is by default installed as a system service with its default username and group name, since this is the default option for the service parameter. If you need to avoid installing Remote Engine as a system service, add --service 0 to the command.

## Results

The Remote Engine is installed and paired.
