What Data for This Category Looks Like
Typically, data for this category comes primarily from CDN consoles, DNS resolution records, user access logs, and monitoring alert systems. Daily maintenance documents include domain name access forms, cache rule configuration tables, refresh and preheating operation records, and fault analysis reports. Data is updated daily or synchronized after each change. Fields include node IP, cache hit rate, request response duration, domain name binding status, and more. There are no unified fixed units; some fields require matching based on specific business scenarios. Abnormal data can cause issues such as slow access, incorrect cache states, failed domain name access, and other related problems.
What Constraints Do These Characteristics Impose on the Deployment and Upgrade Phase
The scattered nature of data sources and the requirement for real-time synchronization mean that multi-console permission configuration and log collection link construction must be completed during the deployment phase. The hierarchical structure of maintenance documentation requires that version mappings of original configurations be retained during upgrades, to avoid misalignment between cache rules and access form information. The high time cost of abnormal node troubleshooting requires that full node configuration pre-verification be completed before upgrades, to prevent batch access anomalies after changes. The pre-deployment requirement of domain name record verification means compliance checks must be completed in the early deployment stage, to avoid subsequent access failures. Unlike cloud network and load balancing configurations, this category targets public network content distribution and caching, so additional attention must be paid to synchronization consistency across regional nodes during deployment.
How to Configure Parameters
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
DB_MAX_LINK | 100–200 connections | Adapts to database connection requirements for CDN node concurrent access, avoids connection pool overflow |
MONGODB_URI | Full connection string with read-write separation suffix | Adapts to FastGPT v4.17.0 multi-node storage architecture, improves cache data read-write efficiency |
REDIS_URL | Exclusive cache instance address for edge nodes | Reduces cross-region cache access latency, meets low-latency requirements of CDN edge acceleration |
FE_DOMAIN | Public network domain name exactly matching the recorded domain | Ensures domain access compliance, avoids browser cross-domain access blocking |
| Cache Rule Activation Delay | 300 seconds | Adapts to the regular synchronization cycle of CDN cache updates, balances real-time performance and node load |
Three Common Misconfigurations
- After upgrade, model configuration is automatically replaced with default values, and the chat interface displays an unexpected large language model. The cause is that persistent caching for model configurations is not set in cache rules. During the upgrade process, edge node caches are cleared, and original configurations are not retained.
- When entering the workflow, a configuration error prompt appears, and the interface displays "Permission verification failed". The cause is that the
ROOT_KEYpermission configuration was not updated synchronously during Docker deployment upgrade, leading to a mismatch between new and old version permission verification logic. - When logging in, a username and password error prompt appears, and the console cannot be accessed. The cause is that the
FILE_TOKEN_KEYencryption parameter was not configured correctly during deployment, leading to a failure of user credential storage verification.
How to Confirm Configuration Is Complete
- Run the domain name record verification script, check the consistency between the
FE_DOMAINconfiguration and record information, confirm there are no domain name binding anomalies. - Connect to the database and run a connection count query, verify that the connection pool upper limit set by
DB_MAX_LINKconfiguration is not triggered. - Trigger a cache refresh operation, check the refresh and preheating records in the CDN console, confirm that the configuration has been synchronized to edge nodes.
- Start the container and run the permission verification script, verify the validity of the
ROOT_KEYandFILE_TOKEN_KEYconfigurations.
