Install LAMs (Moogsoft Enterprise)

This topic describes how to install LAMs in a distributed HA system in Moogsoft Enterprise. In this configuration all components in the HA architecture are on-premise.

In HA architecture, LAM 1 and LAM 2 run in an active / passive mode for a HA polling pair, and in active / active mode for a HA receiving pair.

HA architecture

In our distributed HA installation, the LAM components are installed on the LAM 1 and LAM 2 servers:

Refer to the Distributed HA system Firewall for more information on connectivity within a fully distributed HA architecture.

Install LAM 1

Follow these instructions to install Moogsoft Enterprise on the LAM 1 server.

  1. On LAM 1 install the following Moogsoft Enterprise components (where $VERSION is the version being installed):

    export VERSION=8.2.0;
yum -y install moogsoft-common-${VERSION}* \
    moogsoft-integrations-${VERSION}* \
    moogsoft-utils-${VERSION}*

    Edit your ~/.bashrc file to contain the following lines:

    export MOOGSOFT_HOME=/usr/share/moogsoft
export APPSERVER_HOME=/usr/share/apache-tomcat
export JAVA_HOME=/usr/java/latest
export PATH=$PATH:$MOOGSOFT_HOME/bin:$MOOGSOFT_HOME/bin/utils

    Source the ~/.bashrc file:

    source ~/.bashrc

  2. On LAM 1, edit $MOOGSOFT_HOME/config/system.conf and set the following properties. Substitute the name of your RabbitMQ zone, the server hostnames, and the cluster names:

    "mooms" :
   {
...
"zone" : "<zone>",

"brokers" : [
    {"host" : "<Core 1 server hostname>", "port" : 5672},
    {"host" : "<Core 2 server hostname>", "port" : 5672},
    {"host" : "<Redundancy server hostname>", "port" : 5672}
],
...
"cache_on_failure" : true,
...
"search" :
    {
...
"nodes" : [
    {"host" : "<Core 1 server hostname>", "port" : 9200},
    {"host" : "<Core 2 server hostname>", "port" : 9200},
    {"host" : "<Redundancy server hostname>", "port" : 9200}
]
...
"failover" :
    {
    "persist_state" : true,
    "hazelcast" :
        {
        "hosts" : ["<Core 1 server hostname>","<Core 2 server hostname>"],
        "cluster_per_group" : true
        }
    "automatic_failover" : true,
    }
...
"ha": 
    { "cluster": "PRIMARY" }

Install LAM 2

Follow these instructions to install Moogsoft Enterprise on the LAM 2 server.

  1. On LAM 2 install the following Moogsoft Enterprise components (where $VERSION is the version being installed):

    export VERSION=8.2.0;
yum -y install moogsoft-common-${VERSION}* \
    moogsoft-integrations-${VERSION}* \
    moogsoft-utils-${VERSION}*

    Add the following code to the ~/.bashrc file:

    export MOOGSOFT_HOME=/usr/share/moogsoft
export APPSERVER_HOME=/usr/share/apache-tomcat
export JAVA_HOME=/usr/java/latest
export PATH=$PATH:$MOOGSOFT_HOME/bin:$MOOGSOFT_HOME/bin/utils

    Source the ~/.bashrc file:

    source ~/.bashrc

  2. On LAM 2, edit $MOOGSOFT_HOME/config/system.conf and set the following properties. Substitute the name of your RabbitMQ zone, the server hostnames, and the cluster names:

    "mooms" :
   {
...
"zone" : "<zone>",

"brokers" : [
    {"host" : "<Core 2 server hostname>", "port" : 5672},
    {"host" : "<Core 1 server hostname>", "port" : 5672},
    {"host" : "<Redundancy server hostname>", "port" : 5672}
],
...
"cache_on_failure" : true,
...
"search" :
    {
...
"nodes" : [
    {"host" : "<Core 2 server hostname>", "port" : 9200},
    {"host" : "<Core 1 server hostname>", "port" : 9200},
    {"host" : "<Redundancy server hostname>", "port" : 9200}
]
...
"failover" :
    {
    "persist_state" : true,
    "hazelcast" :
        {
        "hosts" : ["<Core 2 server hostname>","<Core 1 server hostname>"],
        "cluster_per_group" : true
        }
    "automatic_failover" : true,
    }
...
"ha": 
    { "cluster": "SECONDARY" }

Configure a new backend LAM integration as HA on LAM 1 and LAM 2

Follow the instructions in Set Up LAMs for HA.
