安装一路Next就行，安装完毕后，进入目录C:\Program Files\MongoDB\Server\4.2\bin>

启动控制台，输入

cd C:\Program Files\MongoDB\Server\4.2\bin>

C:\Program Files\MongoDB\Server\4.2\bin>mongod -dbpath "d:\mgdb\"

上面这条命令是让以d:\mgdb\为数据库文件所在目录启动db服务。

然后双击mongo.exe启动控制台。

使用以下命令插入数据并查询：

MongoDB Enterprise > use testdb
switched to db testdb

MongoDB Enterprise > db.stats()
{
        "db" : "testdb",
        "collections" : 0,
