版本选择

安装

windows安装完成后
建立三个文件夹
在每个文件夹下面分别创建mongo.log文件

C:\work\mongodb\master

C:\work\mongodb\slave

C:\work\mongodb\arbiter

记得以管理员模式运行cmd，否则报错(非常重要！！！)

cmd 来到bin目录下 分别运行

mongod -port 27111 -bind_ip 0.0.0.0 -dbpath C:\work\mongodb\master -logpath C:\work\mongodb\master\mongo.log -replSet mySet -logappend --install --serviceName "MongoDB-MASTER" --serviceDisplayName "MongoDB-MASTER"

mongod -port 27112  -bind_ip 0.0.0.0 -dbpath C:\work\mongodb\slave -logpath C:\work\mongodb\slave\mongo.log -replSet mySet -logappend --install --serviceName "MongoDB-SLAVE" --serviceDisplayName "MongoDB-SLAVE"

mongod -port 27113  -bind_ip 0.0.0.0 -dbpath C:\work\mongodb\arbiter -logpath C:\work\mongodb\arbiter\mongo.log -replSet mySet -logappend --install --serviceName "MongoDB-ARBITER"  --serviceDisplayName "MongoDB-ARBITER"

运行后查看对应目录的日志文件

执行对应的指令

net start MongoDB-MASTER

其余的slave,arbiter启动如上操作，不再赘述
这里是以服务方式运行，如果需要停止

net stop MongoDB-MASTER

如果需要卸载，卸载服务的指令是

sc delete xxx

然后进入主库端口号

mongo -port 27111

进入数据库后，再执行下面的绑定命令（注意绑定的名字也要是之前定义的mySet）

rs.initiate({"_id":"mySet",members:[{_id:0,host:"127.0.0.1:27111"},{_id:1,host:"127.0.0.1:27112"},{_id:2,host:"127.0.0.1:27113",arbiterOnly: true}]})

arbiterOnly":true}) 添加仲裁节点

从节点设置可操作(可选)，默认不可操作

rs.slaveOk()

输入命令rs.status()查看各个节点的状态信息
