## MongoDB副本集群 ### 架构 ```text ---------------- ---------------- ---------------- | MongoDB® 0 | | MongoDB® 1 | | MongoDB® | | Server | | Server | | Arbiter | | Pod | | Pod | | Pod | ---------------- ---------------- ---------------- primary secondary Arbiter ``` 一主一从一仲裁 ## 如何连接 打开 `MongoDB-replicaset` 组件的对外服务端口进行连接。 默认密码是： * `root` * `mongo@123` ## 验证副本集群可用 进入 `MongoDB-replicaset` 组件的 Web 终端内执行以下命令： ```bash mongosh -u root -p mongo@123 rs.status() ``` `members`字段内出现下述内容代表正常。 ```bash members: [ { _id: 0, name: 'mongo-mongodb-0.mongo-mongodb.e58dcfb46d72493fbabd16dfaa7676d4.svc.cluster.local:27017', health: 1, state: 1, stateStr: 'PRIMARY', uptime: 1283, optime: { ts: Timestamp({ t: 1706782517, i: 1 }), t: Long('2') }, optimeDate: ISODate('2024-02-01T10:15:17.000Z'), lastAppliedWallTime: ISODate('2024-02-01T10:15:17.949Z'), lastDurableWallTime: ISODate('2024-02-01T10:15:17.949Z'), syncSourceHost: '', syncSourceId: -1, infoMessage: '', electionTime: Timestamp({ t: 1706781247, i: 1 }), electionDate: ISODate('2024-02-01T09:54:07.000Z'), configVersion: 5, configTerm: 2, self: true, lastHeartbeatMessage: '' }, { _id: 1, name: 'mongo-mongodb-1.mongo-mongodb.e58dcfb46d72493fbabd16dfaa7676d4.svc.cluster.local:27017', health: 1, state: 2, stateStr: 'SECONDARY', uptime: 1234, optime: { ts: Timestamp({ t: 1706782517, i: 1 }), t: Long('2') }, optimeDurable: { ts: Timestamp({ t: 1706782517, i: 1 }), t: Long('2') }, optimeDate: ISODate('2024-02-01T10:15:17.000Z'), optimeDurableDate: ISODate('2024-02-01T10:15:17.000Z'), lastAppliedWallTime: ISODate('2024-02-01T10:15:17.949Z'), lastDurableWallTime: ISODate('2024-02-01T10:15:17.949Z'), lastHeartbeat: ISODate('2024-02-01T10:15:26.348Z'), lastHeartbeatRecv: ISODate('2024-02-01T10:15:26.293Z'), pingMs: Long('0'), lastHeartbeatMessage: '', syncSourceHost: 'mongo-mongodb-0.mongo-mongodb.e58dcfb46d72493fbabd16dfaa7676d4.svc.cluster.local:27017', syncSourceId: 0, infoMessage: '', configVersion: 5, configTerm: 2 }, { _id: 2, name: 'mongo-mongodb-arbiter-0.mongo-mongodb-arbiter.e58dcfb46d72493fbabd16dfaa7676d4.svc.cluster.local:27017', health: 1, state: 7, stateStr: 'ARBITER', uptime: 406, lastHeartbeat: ISODate('2024-02-01T10:15:27.147Z'), lastHeartbeatRecv: ISODate('2024-02-01T10:15:27.434Z'), pingMs: Long('0'), lastHeartbeatMessage: '', syncSourceHost: '', syncSourceId: -1, infoMessage: '', configVersion: 5, configTerm: 2 } ], ```
