Setting Up a Basic Configuration

The Solace PubSub+ appliance doesn't come set up with a basic configuration of the primary components and services required to permit clients to send and receive messages.

The following procedure shows how to configure a powered up appliance for Direct Messaging utilizing the default SMF messaging service. It then provides steps to configure other optional functionality: Direct Messaging with the optional Web transport service, Guaranteed Messaging, and Message Queuing Telemetry Transport (MQTT) topic syntax support.

To set up a basic configuration, perform the following steps:

Start the Message VPN named default:

solace> enable
solace# configure
solace(configure)# message-vpn default
solace(configure/message-vpn)# no shutdown

Disable authentication on the Message VPN named default:
```
solace(configure/message-vpn)# authentication user-class client
solace(...message-vpn/authentication/user-class)# auth-type none
solace(...message-vpn/authentication/user-class)# end
```
Although no authentication is used here, as a convenience to allow you to quickly get the appliance ready for messaging, Solace strongly recommends against using no client authentication, especially in production scenarios.
Start the client username named default on the Message VPN named default:
```
solace# configure
solace(configure)# client-username default message-vpn default
solace(configure/client-username)# no shutdown
solace(configure/client-username)# end
```
At this point, you should now be able to send and receive Direct messages (see Direct Messages for further information on Direct messaging) using the Solace API samples built according to the Quick Start section in the APIs & Protocols Solace Messaging API Developer Guide.
If you want to enable the Web transport service so that Web-based messaging applications may send Direct messages to, and receive Direct messages from, the appliance, perform the following steps:

Unlock the Web Transport service on the event broker:
```
solace#
solace# admin
solace(admin)# product-key <key-value>
solace(admin)# exit
```
- <key-value> is the Solace-provided product key.
- By default, Web transport service on the appliance is locked, and you require a valid Solace provided product key to unlock it.
Start the Web Transport service:
```
solace(configure)# service web-transport
solace(configure/service/web-transport)# no shutdown
solace(configure/service/web-transport)# end
```
At this point, you should now be able to send and receive Direct messages (see Direct Messages for further information on Direct messaging) using the Solace JavaScript API samples built according to the Quick Start section in the APIs & Protocols Solace Messaging API Developer Guide.

If you want to enable Guaranteed Messaging service so that messaging applications may send Guaranteed messages to, and receive Guaranteed messages from, the appliance, perform the following steps:
To support Guaranteed Messaging, a Solace PubSub+ appliance must have an Assured Delivery Blade (ADB) and Host Bus Adapter (HBA) installed.

Enable the appliance’s internal disk drive for Guaranteed message spooling:
```
solace# configure
solace(configure)# hardware message-spool
solace(configure/hardware/message-spool)# internal-disk
```
Although the internal disk is used here as a convenience to allow you to quickly get the appliance ready for messaging, using the internal disk for Guaranteed Messaging is intended only for test purposes, and shouldn't be used in a production environment.

Start the message spool and set it as the primary:

solace(configure/hardware/message-spool)# no shutdown primary
solace(configure/hardware/message-spool)# end

Set the maximum message spool usage for the Message VPN default to 1000 MB:

solace# configure
solace(configure)# message-spool message-vpn default
solace(configure/message-spool)# max-spool-usage 1000
solace(configure/message-spool)# exit

Configure the client profile named default to allow the client to send and receive Guaranteed messages:

solace# configure
solace(configure)# client-profile default message-vpn default
solace(configure/client-profile)# message-spool
solace(configure/client-profile/message-spool)# allow-guaranteed-message-send
solace(configure/client-profile/message-spool)# allow-guaranteed-message-receive

Configure the client profile named default to allow the client to dynamically create endpoints:
```
solace(configure/client-profile/message-spool)# allow-guaranteed-endpoint-create
solace(configure/client-profile/message-spool)# end
```
At this point, you are now be able to send and receive Guaranteed messages (see Guaranteed Messages for further information on Guaranteed messaging) using the Solace API samples built according to the Quick Start section in the APIs & Protocols Solace Messaging API Developer Guide.

If you want the appliance to support client applications that use MQTT topic syntax for their message topics and subscriptions, perform the following steps:

Enable the system-level service for MQTT messaging:

solace> enable
solace# configure
solace(configure)# service mqtt
solace(configure/service/mqtt)# no shutdown
solace(configure/service/mqtt)# end

Configure a listen port for plain-text MQTT service on the Message VPN default:

solace> enable
solace# configure
solace(configure)# message-vpn default
solace(configure/message-vpn)# service mqtt
solace(configure/message-vpn/service/mqtt)# listen-port 1234

Enable plain-text MQTT service on the Message VPN default:

solace(configure/message-vpn/service/mqtt)# no plain-text shutdown
solace(configure/message-vpn/service/mqtt)# end
