WSO2 IS集群文档疑问：不同配置文件中域名设置差异咨询

Hey there! Let's clear up the confusion around those different domain names you're seeing in WSO2 Identity Server (IS) configuration files, and address the potential documentation inconsistencies you noticed.

What Each Domain Name is For #

Let's break down the role of each domain in its respective config file:

• wso2.is.com (in carbon.xml): This is typically an internal host alias for the WSO2 IS instance itself. The carbon.xml file is the core configuration for the WSO2 Carbon runtime, so this domain is used for internal component communication, self-identification, and certificate validation. It helps the IS server recognize its own network identity for backend processes.
• is.wso2.com (in site.json and web.xml): These files focus on user-facing or web application behavior. site.json manages UI/portal configurations, while web.xml defines web app deployment settings. This domain is intended to be the external, user-accessible address for your IS instance—this is what end users or admins would type into their browsers to access the management console or user portals.
• as.wso2.com (in Nginx config): The "as" here likely stands for Application Server, but this is almost certainly a documentation inconsistency. In a standard WSO2 IS deployment, your Nginx reverse proxy should point to the same external domain you use for user access (like is.wso2.com). Using as.wso2.com here is probably a typo or leftover example from a different WSO2 product that got mixed into the IS docs.

Is This a Documentation Error? #

Yes, this kind of inconsistent domain usage across configuration steps is almost certainly a documentation oversight. In real-world deployments, you should standardize on a single domain (e.g., is.yourcompany.com) across all files unless you have a specific multi-component setup that requires separate internal/external addresses.

Quick Recommendation #

For your deployment:

1. Pick a single, consistent domain (either use a custom domain or stick with is.wso2.com for testing).
2. Update carbon.xml, site.json, web.xml, and your Nginx config to use this same domain.
3. Ensure your DNS or local hosts file resolves the domain to your IS server's IP address.
