Unable to start Marklogic service on AWS - amazon-web-services

Question

I have connected to an AWS instance which was set up for MarkLogic using the AWS Systems Manager. I am trying to start the MarkLogic Server, but I am receiving the following error response:
Set configuration: JAVA_HOME="/usr/lib/jvm/jre-1.8.0-openjdk-1.8.0.252.b09-2.amzn2.0.1.x86_64"
Set configuration: MARKLOGIC_MDB_TYPE=""
Set configuration: AWS_REGION="ap-southeast-2"
Set configuration: AWS_DEFAULT_REGION="ap-southeast-2"
Set configuration: MARKLOGIC_ZONE="ap-southeast-2a"
Initialize Configuration.
AWS Region: ap-southeast-2, ZONE: ap-southeast-2a. INSTANCE: i-08c0992c858711a67

This was the output on the log for mlcmd:

How do I resolve this issue?
If there is more required information, do let me know and I will try to get it

Answer 1

It appears that you are attempting to start a self-managed instance/cluster, while the Managed Cluster feature has not been disabled.
The MarkLogic Managed Cluster feature is the recommended way to deploy a MarkLogic Cluster on AWS so it is enabled by default. Managed clusters are meant to be deployed using the MarkLogic CloudFormation Templates.
Deploying MarkLogic on EC2 Using CloudFormation
The Managed Cluster feature reduces the amount of work necessary to setup the initial cluster, and creates an Auto Scaling Group that will automatically re-launch an instance that gets terminated, and when MarkLogic starts on the new instance, it will remount the associated EBS data drive.
CloudFormation Template Overview
If you wish to have a self-managed cluster, then you will need to create an /etc/marklogic.conf file to disable the feature at startup.

Best Practice Editing MarkLogic Server Environment Variables
I would recommend reviewing the following guide, as it details using both the Managed Cluster feature, as well as self-managed clusters.
