# Installing ABS AI engine software

You can install ABS as a root user or as a non-root user.

## Before you begin

1. Install OpenJDK 11.0.2 on a 64-bit architecture machine. To verify the Java version, run the following command:

   ```
   # java -version
   ```

2. Verify the supported operating systems. PingIntelligence supports RHEL 7.9 and Ubuntu 18.04 LTS.

## About this task

The example installation path assumes that you are root user. The installation works in a similar way for a non-root user.

|   | It is recommended to install only one instance of ABS on each machine. MongoDB should be installed on a different machine from ABS. |

## Steps

1. To install ABS:

   ### Choose from:

   * If you are installing as a root user, change the working directory to `/opt`.

   * If you are installing as a non-root user, choose any other location.

     |   |                                                                                   |
     | - | --------------------------------------------------------------------------------- |
     |   | If you are installing as a non-root user, then increase the `ulimit -n` to 65535. |

2. At the command prompt, enter `# tar –zxvf <file_name>`.

   ### Example:`# tar –zxvf pi-api-abs-5.2.tar.gz`
