ASL supports unattended installations. That means you can use the configuration of one system as the template for a new system. The installer will not ask questions for options that are templated. This document explains how to do an unattended installation.

Important Note

ASL contains a number of new features that are set up on Installation. While you can also configure these features from the ASL web console after its installed, it may be easier to perform a full guided installation once if you have other servers to install. This will save you time needed to enable these new features on the other systems.

Additionally, as a safety feature, the upgrader will ask if you want to re-install the ASL database. If you have important data or events in the database, do not upgrade. Save your events. You must reinstall the database to use ASL4. ASL4 is not compatible with an ASL3 database.


Step A : Copy the configuration file to the system

From a system with ASL already installed, copy this file:


To the system you want to install ASL on, or upgrade, in this file:


Note: You can do this on the same system if you want a totally unattended upgrade of an existing ASL system to occur.

Step B : go to the root users directory

On the new system, without ASL installed:

cd /root/

Step C : run the installer

Run the installer as you normally would as the root on the system with the file /root/asl.cfg

wget -q -O - https://updates.atomicorp.com/installers/asl |sh

Input will only be required if:

  1. The installer encounters an unresolvable error
  2. A major change is detected

Step D : (optional for upgrades only)

Note: This is only required for unattended upgrades. If you are doing an unattended install on a new system, you do not need to run this step.

Once the installation is complete, you must re-install the ASL database. Run this command as root:


Step E: return the normal installation process

Continue with Step 3 in the normal installation process:
