接下来显示如何在一台服务器上面演示部署3个节点的Replica Sets
二、启动Replica服务
分别打开三个命令窗口,然后分别执行下面三句话。
mongod.exe --replSet rs1 --keyFile "D:\Program Files\mongodb\data\replica\key\r0" --port 28010 --dbpath "D:\Program Files\mongodb\data\replica\data\r0" --logpath "D:\Program Files\mongodb\data\replica\log\r0.log" --logappend mongod.exe --replSet rs1 --keyFile "D:\Program Files\mongodb\data\replica\key\r1" --port 28011 --dbpath "D:\Program Files\mongodb\data\replica\data\r1" --logpath "D:\Program Files\mongodb\data\replica\log\r1.log" --logappend cd /d D:\Program Files\mongodb\bin mongod.exe --replSet rs1 --keyFile "D:\Program Files\mongodb\data\replica\key\r2" --port 28012 --dbpath "D:\Program Files\mongodb\data\replica\data\r2" --logpath "D:\Program Files\mongodb\data\replica\log\r2.log" --logappend
