要重命名副本集您必须关闭副本集的所有成员然后使用新的副本集名称配置每个成员的数据库。
此过程需要停机。
先决条件
确保您的副本集未分片。重命名过程仅适用于未分片的副本集。
在重命名副本集之前请 对 MongoDB 部署执行完整备份。
做好备份非常重要无论如何请先在测试环境验证后再执行该操作
启用身份验证后请确保您的用户角色对每个成员数据库中的集合具有 find、insert 和 remove 权限。
db.runCommand({rolesInfo: { role: xxxxx, db: yyyyyy },showPrivileges: true}
)授权
db.getUser(admin)
{_id : admin.admin,userId : UUID(adb37ec9-89e9-464b-a241-029194bec6ef),user : admin,db : admin,roles : [{role : root,db : admin}],mechanisms : [SCRAM-SHA-1,SCRAM-SHA-256]
}db.createRole({role: collectionRole,privileges: [{ resource: { db: local, collection: system.replset }, actions: [ find, remove, insert ] }],roles: []}
)db.grantRolesToUser(admin,[{role:collectionRole,db:admin}])db.getUser(admin)
{_id : admin.admin,userId : UUID(adb37ec9-89e9-464b-a241-029194bec6ef),user : admin,db : admin,roles : [{role : root,db : admin},{role : collectionRole,db : admin}],mechanisms : [SCRAM-SHA-1,SCRAM-SHA-256]
}关闭副本集成员
此步骤需要停机因为所有副本成员都需要关闭。
当前副本集名称 “set” : “sit_rs1”
{set : sit_rs1,date : ISODate(2023-11-10T08:08:08.707Z),myState : 1,......members : [{_id : 1,name : 192.168.88.11:27018,health : 1,state : 2,stateStr : SECONDARY,......},{_id : 3,name : 192.168.88.11:27017,health : 1,state : 1,stateStr : PRIMARY,......},{_id : 4,name : 192.168.88.11:27019,health : 1,state : 2,stateStr : SECONDARY,.....}],ok : 1,$clusterTime : {clusterTime : Timestamp(1699603684, 1),signature : {hash : BinData(0,yDDKmbDiNNhNxzNxh20IjGyr3o),keyId : NumberLong(7236938018798436354)}},operationTime : Timestamp(1699603684, 1)
}关闭副本集成员三台都关闭
# shutdown 27019
su mongodb -s /bin/bash -c /usr/local/mongodb/bin/mongod --dbpath /data/mongodb27019/data --port 27019 --shutdown# shutdown 27018
su mongodb -s /bin/bash -c /usr/local/mongodb/bin/mongod --dbpath /data/mongodb27018/data --port 27018 --shutdown# shutdown 27017
su mongodb -s /bin/bash -c /usr/local/mongodb/bin/mongod --dbpath /data/mongodb/data --port 27017 --shutdown重命名副本集
对每个副本集成员执行以下步骤 以其中一台 27019 为例
在 不带 --replSet 该选项 的情况下在不同端口上启动副本集成员 如下注释掉 replication 选项。 端口改为 28019
