【MONGODB】驗證MONGODB 主從複製

1 實驗主從複製，並驗證複製成功
2 實驗複本集，並驗證自動切換primary成功.

=======================================================================
1.1.啟動master節點：
mongod -dbpath=D:\Program_file\mongo\db1 -logpath=D:\Program_file\mongo\log\mongodb1.log --port 18001 --master  --rest  --nojournal  


1.2.啟動slave1節點：
mongod -dbpath=D:\Program_file\mongo\db2 -logpath=D:\Program_file\mongo\log\mongodb2.log  --port 18002 --slave    --rest  --nojournal   --source localhost:18001

1.3.啟動slave2節點：
mongod -dbpath=D:\Program_file\mongo\db3 -logpath=D:\Program_file\mongo\log\mongodb2.log  --port 18003 --slave    --rest  --nojournal   --source localhost:18001



1.4.開啟主庫，建立立一個庫及表：


D:\Program_file\mongo\mongodb\bin>mongo -port 18001
MongoDB shell version: 2.4.8
connecting to: 127.0.0.1:18001/test
Server has startup warnings:

1.5.開啟從庫，查看建立立的資料庫及表有沒有同步：
D:\Program_file\mongo\mongodb\bin>mongo -port 18002
MongoDB shell version: 2.4.8
connecting to: 127.0.0.1:18002/test
Server has startup warnings:

可以看到，建立立一個庫TEST,表：TEST 及資料都已同步過來了。

2 實驗複本集，並驗證自動切換primary成功，抓圖實驗過程

下面配置為前段時間配置的一個 replset 測試環境：

2.1 建立相關目錄：
mkdir D:\Program_file\mongo\key
mkdir D:\Program_file\mongo\db1
mkdir D:\Program_file\mongo\db2
mkdir D:\Program_file\mongo\db3
mkdir D:\Program_file\mongo\db4



D:\Program_file\mongo\mongodb\bin\mongod.exe --replSet rs1 --keyFile D:\Program_file\mongo\key\r0 -dbpath=D:\Program_file\mongo\db1 -logpath=D:\Program_file\mongo\log\mongodb.log --logappend  --journal --port 28010


D:\Program_file\mongo\mongodb\bin\mongod.exe --replSet rs1 --keyFile D:\Program_file\mongo\key\r1 -dbpath=D:\Program_file\mongo\db1 -logpath=D:\Program_file\mongo\log\mongodb1.log --logappend  --journal --port 28011

D:\Program_file\mongo\mongodb\bin\mongod.exe --replSet rs1 --keyFile D:\Program_file\mongo\key\r2 -dbpath=D:\Program_file\mongo\db2 -logpath=D:\Program_file\mongo\log\mongodb2.log --logappend  --journal --port 28012

D:\Program_file\mongo\mongodb\bin\mongod.exe --replSet rs1 --keyFile D:\Program_file\mongo\key\r3 -dbpath=D:\Program_file\mongo\db3 -logpath=D:\Program_file\mongo\log\mongodb3.log --logappend  --journal --port 28013

--檔案拷貝後添加--fastsync 參數啟動（拷貝的如果不是primary,啟動後拷貝前的節點會變為primary)
D:\Program_file\mongo\mongodb\bin\mongod.exe --replSet rs1 --keyFile D:\Program_file\mongo\key\r4 -dbpath=D:\Program_file\mongo\db4 -logpath=D:\Program_file\mongo\log\mongodb4.log --logappend  --journal --port 28014 --fastsync


#share:

D:\Program_file\mongo\mongodb\bin\mongod.exe --shardsvr --port 20000 -dbpath=D:\Program_file\mongo\shard\shard0\db -logpath=D:\Program_file\mongo\shard\shard0\log\mongo.log --logappend --journal --directoryperdb

D:\Program_file\mongo\mongodb\bin\mongod.exe --shardsvr --port 20001 -dbpath=D:\Program_file\mongo\shard\shard1\db -logpath=D:\Program_file\mongo\shard\shard1\log\mongo.log --logappend --journal --directoryperdb

#config
D:\Program_file\mongo\mongodb\bin\mongod.exe --configsvr --port 30000 -dbpath=D:\Program_file\mongo\shard\config -logpath=D:\Program_file\mongo\shard\config\mongo.log --logappend --journal --directoryperdb

#route
D:\Program_file\mongo\mongodb\bin\mongos.exe  --port 40000 --configdb localhost:30000 --logpath=D:\Program_file\mongo\shard\config\route.log --logappend  --chunkSize 1

2.2 配置rs

config_rs1={_id:'rs1',members:[
{_id:0,host:'localhost:28010',priority:1},
{_id:0,host:'localhost:28011'},
{_id:0,host:'localhost:28012'},
{_id:0,host:'localhost:28013'},
{_id:0,host:'localhost:28014'}]};
rs.initiat(config_rs1);

2.3 關閉primary,

rs1:PRIMARY> use admin
rs1:PRIMARY> runCommand("shutdown");


2.4 #登入另一節點：
