Windows下MongoDB安裝副本集

• 安裝環境簡介
  Windows十、MongoDB4.0.三、Robo 3T(mongo命令行操做比較方便)

• 建立數據庫文件夾、配置文件等

  （1）數據庫文件夾：db2701七、db3701七、db47017
    （2）log文件夾：log2701七、log3701七、log47017
    （3）配置文件：mongod2701七、mongod3701七、mongod47017
    配置文件更改端口號便可，具體內容以下：
    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

• 啓動primary

                     }
             }
     }
    #副本集配置並啓動

                         }
                 ]
         }

                     }
             }
     }

                     }
             }
     }

  以上副本集建立完成，接下來看下數據同步

  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

  

  以上就是搭建的全過程，後續學習再補充這塊內容~
