Create Sharded Cluster
Create Sharded Cluster The operation content is divided into the following two parts:
- Prerequisites
- Procedure
MongoDB Sharded Cluster is a solution for scaling MongoDB database performance and capacity. It enables horizontal scalability by spreading data across multiple servers, improving the performance of read and write operations and allowing larger amounts of data to be stored. Sharded Cluster deployment method provides high availability mechanism and horizontal expansion. Recommended for use in production.
Sharded Cluster can be created using Whaleal Platform, and nodes can be added, upgraded or downgraded.
Prerequisites
Before deploying Sharded Cluster, you must ensure that the Host has been managed by WAP. If not, please add EC2 or add K8S first
Before deploying Sharded Cluster, you must ensure that MongoTar is available in the WAP. If not, please upload MongoTar first
Procedure
1. Enter the navigation directory
a. Click the MongoDB options button
b. Select the MongoList option. The page displays the MongoDB Cluster that all users can operate.
2. Create ReplicaSet
a. Click the Create Project button on the right
b. Select the Sharding option
3. Configure Sharded Cluster
Sharded cluster configuration
| Configuration items | value |
|---|---|
| Affiliated project | Select the affiliated project |
| Cluster name | Sharded cluster name |
| Whether to enable authentication | No authentication is enabled: Do not set user password Account number and password: Turn on authentication and set user password Account and password and CA certificate: Turn on authentication, set user password and use CA certificate |
| Version | Select the MongoTar corresponding to the Standalone version to create |
Member configuration
Shard Settings
| Configuration items | value |
|---|---|
| member | member type： member node：Nodes that carry data have voting rights and can be elected as master nodes. hidden node：Node that carries data, has voting rights, and the configuration parameter is hidden Hide delay nodes：The node that carries data has voting rights and the configuration parameters are slaveDelay and hidden |
| hostname | Select the host where the Sharded Cluster node is deployed |
| port | The port used by the node |
| vote | Number of votes cast during replica set election |
| priority | The priority during replication set election. If the priority is 0, the node cannot be elected as the primary node. |
| Delay | The time the node lags behind the master node (unit: seconds), only used for members who are hidden delayed nodes |
| Build index | true：MongoDB build index false：MongoDB does not build index |
| data directory | Sharded Cluster node data file storage directory (absolute path) |
| log file | Sharded Cluster node log output file (absolute path) |
| add | Add member node |
| add Shard | Add a shard cluster |

| Write Concern Majority Journal Default | Whether to return after writing to the majority of nodes |
| Heartbeat Timeout(secs) | Heartbeat detection time between member nodes |
| Election Timeout(ms) | When the member node is unreachable from the master node, check the time |
| CatchUp Timeout(ms) | The catch-up time between the newly elected master node and the latest write operation |
| CatchUp Takeover Delay(ms) | After the member node leads the master node, it waits for the master node time |
