Windows下MongoDB安装副本集

摘要：安装环境简介命令行操作比较方便创建数据库文件夹配置文件等数据库文件夹文件夹配置文件配置文件更改端口号即可，具体内容如下启动查看状态副本集配置并启动添加其他成员这次指定参数，以为创建一个仲裁接点查看副

安装环境简介
Windows10、MongoDB4.0.3、Robo 3T(mongo命令行操作比较方便)

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:mongolog27017mongod27017.log
   
   storage:
       dbPath: E:mongodb27017
       journal:
           enabled: true
       engine: wiredTiger
   
   #processManagement:
   #    fork: true
   #    pidFilePath: E:mongomongod27017.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~
