1. 副本集的搭建
2.物理备份文件
直接备份目录即可
/data/mongodb/rs1
3.在新的机器恢复
3.1 启动节点
/home/mongodb/mongodb/bin/mongod --replSet rs --dbpath /data/mongodb/rs1 --port 27017 --fork --logpath /data/mongodb/rs1/mongod.log --bind_ip_all
/home/mongodb/bin/mongo
3.2 查看状态
由于在新的环境ip发生的变化，会出现下面的报错
> rs.status()
{
"ok" : 0,
"errmsg" : "Our replica set config is invalid or we are not a member of it",
"code" : 93,
"codeName" : "InvalidReplicaSetConfig"
}
3.3 进行配置
rs.reconfig({_id: "rs",version: 1,members: [{ _id: 0, host : "localhost:27017" }]},{force:true})3.4 验证元数据的正确性
> rs.reconfig({_id: "rs",version: 1,members: [{ _id: 0, host : "localhost:27017" }]},{force:true})
{ "ok" : 1 }
