安装过程：
1.在解压后的mongodb的文件夹里建立 data文件（再往里添加db文件）和logs文件（新建mongodb.log）;
eg:
D:\MongoDB\data\db
D:\MongoDB\logs\mongodb.log
2.在CommadLine里进入D:\MongoDB\bin>
执行命令 mongod –dbpath D:\MongoDB\data\db
3.安装Windows服务配置

服务无法启动100、48问题：
1.删掉Mongodb\data\db文件里的mongodb.lock
2在CL删掉之前的服务配置

3.去掉 –directoryperdb后重新加载配置
mongod --logpath "D:\mongodb\logs\mongodb.log" --logappend --dbpath "D:\mongodb\data" --serviceName "MongoDB" --serviceDisplayName "MongoDB" --install
0 0
