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。
