The normal operation of a FanRuan project depends not only on the FineBI/FineReport/FineDataLink application, but also on the configuration database, log service, and cluster components.
FineOps provides a Cluster Configuration page, on which you can manage, configure, and switch components.
Log in to FineOps as the admin, click the target project, and choose Maintenance > Cluster Management, where you can perform basic connection configuration and advanced cluster configuration.
1. The configurations in this section are linked with the configuration database and cluster management configurations in System Management on the FanRuan application platform. Modifications made on either side take effect on both.
2. Some components require plugins to connect to the project. Ensure that you have installed the relevant plugins in the project before configuring the components.
In FanRuan applications, you (the admin) typically set up users, mount directories, assign the permission, and configure timed scheduling on the platform.
The configuration is stored in the configuration database.
In a production environment, you can prepare a database and connect it to the FanRuan application for configuration storage.
A stable external database ensures the stable operation of the FanRuan application under high load.

The state server is primarily used to store and update application state data, enabling multiple clients to access and modify data concurrently.
The state server of a FanRuan cluster mainly stores and caches login information, template locks, SessionIDs, and WebSocket connections while authenticating all access and operations.
Redis standalone is the simplest to deploy, as it requires deploying only one Redis application.
It is also the simplest one to use, as you only need to configure the host, port, and password.
You do not need to consider data sharding or clustering issues. The O&M cost is low.
A single point of failure may occur. A single server cannot achieve high availability and load balancing.
Redis Primary-Replica Cluster
A Redis cluster adopts a shard-based architecture that distributes data across multiple nodes, enabling horizontal scaling and high availability.
If the primary node crashes, the corresponding replica node will be promoted as the new primary node.
All clients pointing to the original primary node are notified of the new primary node's address.
The new primary node synchronizes data from other replica nodes to ensure data consistency.
Compared with the primary-replica mode, the sentinel mode offers higher availability.
It involves primary nodes, replica nodes, and sentinel nodes.
Redis Sentinel clusters require more resources, incurring higher O&M costs.
TencentDB for Redis is a cache and storage service built by Tencent Cloud that is compatible with the Redis protocol.
It supports primary-replica hot standby and provides a full suite of database services, including automatic failover, data backup, instance migration, instance monitoring, online scaling, and data restoration.
File Transfer Protocol (FTP) is a standard protocol for transferring files between computer networks. It is supported by most operating systems and FTP clients.
Note
:
Manually building a local HDFS file system requires strong O&M capabilities, and it cannot satisfy the need for a highly available file server.
By installing the S3 Resource Repository plugin, you can connect a FanRuan cluster to a cloud storage file system that supports the S3 protocol and use it as the file server.
Supported cloud storage file systems include Alibaba Cloud OSS, Huawei Cloud OBS, and Amazon S3. Other self-built S3 platforms are not guaranteed to be supported.
NAS is a file-level storage device that performs file access through standard network protocols (such as SMB/CIFS and NFS), suitable for large organizations that need centralized file management, backup, and sharing.
A single NAS file system can be mounted to multiple nodes, allowing these nodes to share the file system, which saves significant copying and synchronization costs.
Using Huawei Cloud OBS as the Data Storage Server
Using Alibaba Cloud OSS as the Data Storage Server
For FineBI 6.1 projects, you can prepare an S3 component to store the basic tables and self-service datasets extracted in FineBI.
FanRuan recommends that you prepare a cloud storage file system that supports the S3 protocol as the data storage server.
Supported cloud storage file systems include Alibaba Cloud OSS, Huawei Cloud OBS, and Amazon S3.
If the file server of a cluster project is disconnected, business content during the disconnection period will be lost.
From FineOps V2.30.0, anomaly detection has been added for file servers in clusters, which checks the file server configuration of cluster projects every two minutes.
If the file server configuration of a cluster is abnormal, Exception will be displayed on the project card. Refer to the documents above to restore the connection to the file server.
During the disconnection period, you (the admin) cannot use FineOps to perform operations such as restoring and upgrading projects or entering the developer mode.
