# Starting and stopping ASE

Learn how to start and stop ASE.

## Before you begin

For ASE to start, the `ase_master.key` must be present in the `/opt/pingidentity/ase/config` directory. If you have moved the master key to a secured location for security reasons, copy it to the `config` directory before executing the `start` script.

Before starting ASE, make sure that the `nofile` limit in `/etc/security/limits.conf` is set to at least 65535 or higher on the host machine. Run the following command on the ASE host machine to check the `nofile` limit:

```
ulimit -n
```

## About this task

You can start ASE in one of the following two ways:

* Using service script available in the `util` directory, or

* Using the `start.sh` script available in the `bin` directory.

## Steps

1. Start ABS.

   ### Choose from:

   * To start ASE as a service:

     1. Navigate to the `util` directory and run the following command to install ASE as a service:

        ```
        #sudo ./install-systemctl-service.sh pi-ase
        ```

     2. Start the service by entering the following command:

        ```
        systemctl start pi-ase.service
        ```

   * To start ASE using the `start.sh` script:

     1. Change the working directory to `bin`.

     2. Run the `start.sh` script:

        ```
        /opt/pingidentity/ase/bin/start.sh
        Starting API Security Enforcer 5.0...
        please see /opt/pingidentity/ase/logs/controller.log for more details
        ```

2. Stop ASE.

   ### Choose from:

   * To stop ASE using the `stop.sh` script:

     1. Change the working directory to `bin`.

     2. Run the `stop.sh` script:

        ```
        /opt/pingidentity/ase/bin/stop.sh -u admin –p admin
        checking API Security Enforcer status…
        sending stop request to ASE. please wait…
        API Security Enforcer stopped
        ```

   * To stop ASE using a service script:

     1. Run the following command:

        ```
        systemctl stop pi-ase.service
        ```
