mongo学习- 副本集配置(事故自动转移)

时间:2022-04-30 00:58:03

一。安装mongodb

二。复制2份

三。启动

(1)mongod --config C:\mongofuben\zhu\conf\mongodb.config --replSet haibin/127.0.0.1:27018

(2)   mongod --config C:\mongofuben\fu1\conf\mongodb.config --port 27018 --replSet haibin/127.0.0.0:27017

(3)运行  在admin库运行

db.runCommand({
replSetInitiate:{
_id:"haibin",
members:[
{
_id: 0,
host:"127.0.0.1:27017"
},
{
_id:1,
host:"127.0.0.1:27018"
}
]
}
})

  运行 rs.status() 查看状态

}

  (4)mongod --config C:\mongofuben\fu2\conf\mongodb.config --port 27019 --replSet haibin/127.0.0.0:27017 (添加仲裁者)

(5)rs.addArb("127.0.0.1:27019")(见上面的返回结果)

(6)主动结束27017端口,查看状态。
