创建必要的目录和认证文件：
[root@mongo mongo]# mkdir keyfile
[root@mongo mongo]# echo "mongo cluster one" > keyfile/m1
[root@mongo mongo]# echo "mongo cluster one" > keyfile/m2
[root@mongo mongo]# echo "mongo cluster one" > keyfile/m3
启动不同端口的服务
mongod --replSet mco --keyFile /usr/local/mongo/keyfile/m1 --fork --port 28010 --dbpath=/usr/local/mongo/data0/ --logpath=/usr/local/mongo/log/m1.log --logappend
mongod --replSet mco --keyFile /usr/local/mongo/keyfile/m2 --fork --port 28011 --dbpath=/usr/local/mongo/data1/ --logpath=/usr/local/mongo/log/m2.log --logappend
mongod --replSet mco --keyFile /usr/local/mongo/keyfile/m3 --fork --port 28012 --dbpath=/usr/local/mongo/data2/ --logpath=/usr/local/mongo/log/m3.log --logappend
mongod --replSet mco --keyFile /usr/local/mongo/keyfile/m4 --fork --port 28013 --dbpath=/usr/local/mongo/data3/ --logpath=/usr/local/mongo/log/m4.log --logappend
mongod --replSet mco --keyFile /usr/local/mongo/keyfile/m5 --fork --port 28014 --dbpath=/usr/local/mongo/data4/ --logpath=/usr/local/mongo/log/m5.log --logappend --fastsync
