This document provides instructions for configuring multiple API manager instances to avoid port conflicts and share authentication. The key steps are: 1. Maintain 3 separate API manager instances and change the "offset" value in carbon.xml to avoid port conflicts. 2. Disable the Thrift server in the second and third instances by changing the api-manager.xml. 3. Configure the authentication manager and API key validator in the second and third instances to point to the first instance for authentication. 4. Add environment configurations for two gateways to the first instance's api-manager.xml file.

2. CONFIGURATION
• First we have to maintain 3 or more API
managers(wso2am) separately.
• Then change all servers “offset” value for
avoiding port conflict.
(wso2am-1.10.0repositoryconfcarbon.xml)

3. Cont…
• Open
the <APIM_HOME>/repository/conf/api-
manager.xml files in the second and the
third API Manager instances and set
the <EnableThriftServer> property to false
(by default true).

4. • Open
the <APIM_HOME>/repository/conf/api-
manager.xml files in the second and the
thirdGateway instances and change the
following
<AuthManager>
<ServerURL>https://<IP of the first instance>:9443/services/</ServerURL>
<Username>admin</Username>
<Password>admin</Password>
...
</AuthManager>

5. • Ex
• <AuthManager>
<ServerURL>https://192.168.1.145:9444/services/</ServerURL>
<Username>admin</Username>
<Password>admin</Password>
………..
</AuthManager>

7. • And change here also
<APIKeyValidator>
<ServerURL>https://<IP of the first instance>:9443/services/</ServerURL>
<Username>admin</Username>
<Password>admin</Password>
....
<RevokeAPIURL>https://<IP of the first
instance>:8243/revoke</RevokeAPIURL>
</APIKeyValidator>

8. • Ex
<APIKeyValidator>
<ServerURL>https:// 192.168.1.145:9444/services/</ServerURL>
<Username>admin</Username>
<Password>admin</Password>
....
<RevokeAPIURL>https:// 192.168.1.145:9444/revoke</RevokeAPIURL>
</APIKeyValidator>

10. • Open
the <APIM_HOME>/repository/conf/api-
manager.xml file in the first API Manager
instance.
• Add two API Gateway environments under
the <Environments> element and delete
the <environment> that comes by default.

11. <Environments>
<Environment type="production">
<Name>Production Gateway</Name>
<Description>Production Gateway Environment</Description>
<ServerURL>https://localhost:9444/services/</ServerURL>
<Username>admin</Username>
<Password>admin</Password>
<GatewayEndpoint>http://localhost:8281,https://localhost:8244</GatewayEndpoi
nt>
</Environment>
<Environment type="sandbox">
<Name>Sandbox Gateway</Name>
<Description>Sandbox Gateway Environment</Description>
<ServerURL>https://localhost:9445/services/</ServerURL>
<Username>admin</Username>
<Password>admin</Password>
<GatewayEndpoint>http://localhost:8282,https://localhost:8245</GatewayEndpoi
nt>
</Environment>
</Environments>

13. • Then start the all servers.
• Copy the first instance IP address of publisher
and enter the credentials.
• Note:- second and third servers will not open
on browser.
