WSO2 API Manager Gateway clustering. How to setup

问题:

I have a plan to use WSO2 API manager for my company, so trying to make it work clustering.

it consists of Keymanager, Gateway(manager, worker), Publisher, Store on 2 AWS instances.

Host1 contains Keymanager, Gateway manager, Publisher, Store. Host2 contains Gateway worker.

the point that I'm confusing is how to configure correct setting for in the /repository/conf/api-manager.xml file.

Case 1) set gateway.manager.com in GatewayEndpoint

<APIGateway>
  . . . 
    <ServerURL>https://gateway.manager.com:9444/services/</ServerURL>
    <Username>admin</Username>
    <Password>admin</Password>
    <GatewayEndpoint>http://gateway.manager.com:8281, https://gateway.manager.com:8244</GatewayEndpoint>
. . .
</APIGateway>

Case 2) set gateway.worker.com in GatewayEndpoint

<APIGateway>
  . . . 
    <ServerURL>https://gateway.manager.com:9444/services/</ServerURL>
    <Username>admin</Username>
    <Password>admin</Password>
    <GatewayEndpoint>http://gateway.worker.com:8280, https://gateway.worker.com:8243</GatewayEndpoint>
. . .
 </APIGateway>

You don't need to APIGateway configuration on Gateway Manager, since you are using Gateway Manager, Key Manager, Publisher, Store in one node.

You can configure you Gateway Manager node as below

<APIGateway>
    <Environments>
        <Environment type="hybrid">
        ...
            <ServerURL>https://gateway.manager.com:9443/services/</ServerURL> <!-- To deploy API to gateway Manager -->
            <Username>admin</Username>
            <Password>admin</Password> 
            <GatewayEndpoint>http://gateway.worker.com:8280,https://gateway.worker.com:8243</GatewayEndpoint> <!-- To show the gateway worker URLs for API in API Store -->
        </Environment>
    </Environments> 
    ...
</APIGateway>

You don't need to configure anything on Gateway Worker Node.

You dont need to define gateway manager URL in gateway endpoints section. Gateway endpoints section will be used at API store to list API gateway URLs when you click on API and see details. So you can use following configurations for all nodes without any issue.

<GatewayEndpoint>http://gateway.worker.com:8280, https://gateway.worker.com:8243</GatewayEndpoint>

You need to define gateway server URL as follows in publisher mainly because it will use this URL to publish API to gateway manager.

<ServerURL>https://gateway.manager.com:9444/services/</ServerURL>
