## Description
此仓库是NestJs 使用 mongoose 操作Mongodb 数据库 和 事务


// 基础版

windows 本地软件下载

MongoDB : https://www.mongodb.com/try/download/community  （会自动勾选下载MongoDB Compass， 最好下载，当然也可以用Navicat 去查看对应数据库）

MongoDB Shell： https://www.mongodb.com/try/download/shell

事务 - 本地开发:

 **1、app.module文件** 

```
import { Module } from '@nestjs/common';
import { AppController } from './app.controller';
import { AppService } from './app.service';
import { MongooseModule } from '@nestjs/mongoose';
import { DogModule } from './dog/dog.module';

@Module({
  imports: [
    MongooseModule.forRoot('mongodb://localhost:27017/dashan-test', {
      maxPoolSize: 1000, // 设置连接池大小为10
      connectTimeoutMS: 10000, // 设置连接超时时间为5秒
      socketTimeoutMS: 60000, // 设置套接字超时时间为45秒、
      w: 'majority',
      // 重要：启用副本集事务支持
      replicaSet: 'rs0' // 开发环境可用单节点副本集
    }),
    DogModule 
  ],
  controllers: [AppController],
  providers: [AppService],
})
export class AppModule {}

```

 **2、MongoDB.config 里加相关配置 replication: replSetName: rs0, 添加rs0事务副本** 

```
# mongod.conf

# for documentation of all options, see:
#   http://docs.mongodb.org/manual/reference/configuration-options/

# Where and how to store data.
storage:
  dbPath: C:\Program Files\MongoDB\Server\8.0\data

# where to write logging data.
systemLog:
  destination: file
  logAppend: true
  path:  C:\Program Files\MongoDB\Server\8.0\log\mongod.log

# network interfaces
net:
  port: 27017
  bindIp: 127.0.0.1

#processManagement:

#security:

#operationProfiling:

#replication: 重点加以下配置
replication:
    replSetName: rs0   
#sharding:

## Enterprise-Only Options:

#auditLog:

```

 **3、管理员身份权限在mongodb 的目录下，例如：C:\Program Files\MongoDB\Server\8.0， 运行cmd，输入以下命令** 

 `mongod --replSet rs0 --port 27017 --dbpath /data/db --bind_ip localhost`


 **4、在windows里重启MongoDB服务** 


 **5、MongoDB Shell里 输入数据库名称并初始化, 例如dashan-nest数据库，调起事务副本** 

![输入图片说明](1111.png)

输入下方命令初始化

```
// 初始化
rs.initiate()

// 查看状态
rs.status()

```
