# Starting ABS

## Steps

1. To start API Behavioral Security (ABS), run the `start.sh` script located in the `/opt/pingidentity/abs/bin` directory.

   |   | To start ABS, you must accept the EULA. You can accept the EULA in two ways:- Scroll through the text on screen and enter `yes` to accept the EULA.

   - Use the `--acceptLicense` option with `start.sh` as shown in the screen output below:

     ```shell
     $ /opt/pingidentity/abs/bin/start.sh --acceptLicense
     End-User License Agreement accepted
     Starting API Behavioral Security Version 4.1...
     please see /opt/pingidentity/abs/logs/abs/abs.log for more details
     ```After you accept the EULA, ABS creates a `license.accepted` file in the `/opt/pingidentity/abs/config` directory, which ABS checks for on subsequent starts. |

2. To verify that ABS has started, change the working directory to the `data` directory and look for two `.pid` files, `abs.pid` and `stream.pid`.

3. Make sure that the newly added ABS node is connecting to MongoDB and has a heartbeat.

   ### Example:

   ```
   > use abs_metadata
   switched to db abs_metadata
   > db.abs_cluster_info.find().pretty()
    {
