NATS Setup

This configuration should be applied to the Main Primary, Arbiter and Secondary Primary servers ONLY.

  1. Edit Configuration: Update the /etc/nats-server.conf file with the following settings:

    Code Block
    languagejson
    server_name: "opha-dev1.opmantek.net"  #The local server  
http_port: 8222 
listen: 4222 
jetstream: enabled 

#tls {
#    cert_file: "<path>"
#    key_file:  "<path>"
#    #ca_file:   "<path>"
#    verify: true
#}

log_file: "/var/log/nats-server.log"

accounts { 
  $SYS { 
    users: [ 
      { user: "admin",
        pass: "password" 
      } 
    ] 
  } 
  ophad: { 
    users: [ 
        { user: "omkadmin", password: "op42opha42" } 
    ] 
    jetstream: enabled 
  } 
} 

jetstream { 
  store_dir: "/opt/nats/storage" 
  max_memory_store: 1028M 
  max_file_store: 1028M 
} 
cluster { 
  name: "C1" 
  host: "opha-dev1.opmantek.net"  #The current host 
  # the current server 
  listen: "0.0.0.0:6222" 
  routes: [ 
    # secondary primary
    "nats://opha-dev6.opmantek.net:6222" 
    # server with the arbiter 
    "nats://opha-dev2.opmantek.net:6222" 
    # other servers 
  ] 
}

...

Common Configuration for All Servers

...

Update /usr/local/omk/conf/opCommon.json

  1. Backup Configuration: Make a backup copy of the opCommon.json file before making any changes.

  2. Add NATS Cluster Configuration: Ensure the following configuration is included in opCommon.json on all servers. In the below example we have added the Main Primary, arbiter and Secondary Primary FQDNs and port/s to be utilized in the nats_cluster attribute, you can find this in the database section.

    Code Block
    languagejson
    "nats_cluster": [ "opha-dev1.opmantek.net", "opha-dev2.opmantek.net", "opha-dev6.opmantek.net" ]

...

Server-Specific Configuration

...

Update /usr/local/omk/conf/opCommon.json for Main Primary and Secondary Primary only

Code Block
languagejson
"db_replica_set": "rs1", 
"db_mongo_cluster": [ "opha-dev1.opmantek.net", "opha-dev6.opmantek.net" ], 
"nats_num_replicas": 3, 
"nats_cluster": [ "opha-dev1.opmantek.net", "opha-dev2.opmantek.net", "opha-dev6.opmantek.net" ]

...

MongoDB Setup (Main Primary Only)

The following steps should be performed only on the Main Primary MongoDB instance.

...

Initialize MongoDB Replica Set

Connect to MongoDB using the mongosh command and configure the replica set:

...

Code Block
rs.initiate({ _id: "rs1", version: 1, members: [ { _id: 0, host : "opha-dev1.opmantek.net:27017", priority: 2 }, { _id: 1, host : "opha-dev6.opmantek.net:27017", priority: 1 } ] })

...

Set Default Write Concern

Run the following command to set the default write concern:

Code Block
db.adminCommand({ "setDefaultRWConcern": 1, "defaultWriteConcern": { "w": 1 } })

...

Add Arbiter

Run the following command to add an arbiter to the replica set:

Code Block
rs.addArb("opha-dev2.opmantek.net:27018")

...

Restart mongod on the Main Primary, Second Primary and Arbiter

Run the following command on the Main Primary, Secondary Primary, and Arbiter servers ONLY:

Code Block
sudo systemctl restart mongod

...

Starting Services

...

Start NATS

Start the NATS service on the Main Primary, Secondary Primary, and Arbiter servers ONLY:

Code Block
systemctl start nats-server

...

Restart mongod on Pollers and Mirrors only

After configuration changes, restart mongod on all Mirrors and Pollers servers ONLY:

Code Block
systemctl restart mongod

...

Restart services on all servers

After configuration changes have been made, you will need to restart the relevant FirstWave module daemons applicable to your server.

...

Code Block
systemctl restart nmis9d opchartsd opeventsd omkd ophad

...

Start the Poller and Mirrors

Execute the following command on the poller and mirror servers.

Code Block
cd /usr/local/omk/bin
./ophad cmd producer start

...

Final Steps

  1. Accept EULAs: Make sure when you login to each server to confirm that all End User License Agreements (EULAs) are accepted.

...

Upgrade to opHA-5.1.0 from opHA 4.X

...

Prerequisites
