Service and Data Maintenance
Data services and file services must be handled carefully. Confirm backups and impact scope before stopping or restarting production services.
Data Maintenance Notes
- Do not stop data services directly while users are active.
- Confirm backups before operating on databases or file storage.
- Start data services before project services after a server reboot.
Gofastdfs File Server
Check 'Gofastdfs' when files cannot be sent, downloads fail, or images are broken. Always check disk space before restarting the file service.
Redis Service
Check Redis when cache, session, or fast state synchronization behaves abnormally.
Hbase, Hadoop, and Zookeeper Chat Database
These services are related to chat data storage and coordination. If the data server shuts down abnormally, confirm that all required services are healthy before starting project services.
Shutdown Order
Stop project services before stopping data services whenever possible.
Startup Order
- Firewall
- 'Redis'
- 'Hadoop', 'Hbase', and 'Zookeeper'
- 'Mysql'
- Duli project services
Mysql Database
Check Mysql when the admin console, organization, account, order, or business data is abnormal.
