Windows下MongoDB安装副本集

创建数据库文件夹、配置文件等

（1）数据库文件夹：db27017、db37017、db47017
  （2）log文件夹：log27017、log37017、log47017
  （3）配置文件：mongod27017、mongod37017、mongod47017
  配置文件更改端口号即可，具体内容如下：
  λ cat mongod27017.conf
   systemLog:
       destination: file
       logAppend: true
       path: E:\mongo\log27017\mongod27017.log
   
   storage:
       dbPath: E:\mongo\db27017
       journal:
           enabled: true
       engine: wiredTiger
   
   #processManagement:
   #    fork: true
   #    pidFilePath: E:\mongo\mongod27017.pid
   
   net:
       port: 27017
   
   replication:
       replSetName: mongo

以上副本集创建完成，接下来看下数据同步

mongo:PRIMARY> show dbs
   admin   0.000GB
   config  0.000GB
   local   0.000GB
   mongo:PRIMARY> use mongo
   switched to db mongo
   mongo:PRIMARY> db.createCollection("test")
   {
           "ok" : 1,
           "operationTime" : Timestamp(1541686077, 1),
           "$clusterTime" : {
                   "clusterTime" : Timestamp(1541686077, 1),
                   "signature" : {
                           "hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="),
                           "keyId" : NumberLong(0)
                   }
           }
   }
   mongo:PRIMARY> show collections
   test

以上就是搭建的全过程，后续学习再补充这块内容~
