# Start and Stop ASE

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 `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
```

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.

## Start ASE as a service

Complete the following steps 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
   ```

## Start ASE using start.sh script

Change working directory to `bin`and 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
```

## **Stop ASE using stop.sh**

Change working directory to `bin` and 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
```

## Stop ASE using service script

Run the following command to stop the ASE service:

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