MongoVUE无法看到collection明细记录的解决方法

MongoDB 3.2之后默认启动的是wiredTiger 引擎这个引擎和原来的引擎访问方式不一样。你用命令mongod  --storageEngine mmapv1 --dbpath 数据目录 这样启动的是原来的数据引擎在用MongoVE连接就可以了

　详见：http://my.oschina.net/chiyong/blog/599326?fromerr=I2dldtre

 ps，wiredTiger为新版存储引擎，性能比mmapv1 要好，启用压缩后，占用的存储空间按比mmapv1小。详见：http://my.oschina.net/chiyong/blog/599326?fromerr=I2dldtre

其他更好的方法，用Robomongo替换MongoVE，可以支持两种存储引擎。

setup.bat

cd C:Program FilesMongoDBServer3.2in
mongod.exe --storageEngine mmapv1 --logpath "C:	empmongodblogmongodb.log" --logappend --dbpath "C:	empmongodbdata" --port 6111 --serviceName "MongoDB" --serviceDisplayName "MongoDB Server" --install

net start MongoDB

pause

remove.bat

cd C:Program FilesMongoDBServer3.2in
mongod.exe --storageEngine mmapv1 --logpath "C:	empmongodblogmongodb.log" --logappend --dbpath "C:	empmongodbdata" --port 6111 --serviceName "MongoDB" --serviceDisplayName "MongoDB Server" --install

net start MongoDB

pause

MongoDB安全相关，服务启动加参数 --auth，设置用户名密码，见官方文档：https://docs.mongodb.com/manual/reference/method/db.createUser/

> db.createUser({user:"wilson",pwd:"123456",roles:[]})
Successfully added user: { "user" : "wilson", "roles" : [ ] }
>

 加了验证后的访问url为：

"mongodb://user1:123@192.168.160.132/dbdemo1/?socketTimeout=1s";

db.createUser( { user: "admin",
                 pwd: "admin123", 
                 roles: [ { role: "readWrite", db: "gps_current_ps" },
                          { role: "readWrite", db: "ob_active_ps" },
                            { role: "readWrite", db: "StudentDB" }
                          ]} )


db.auth( {
   user: "admin",
   pwd: "admin123", 
} )                          

使用MongoDB.Driver.GridFS进行文件读写操作

using System.IO;
using System.Linq;
using System.Text;
using MongoDB.Driver;
using MongoDB.Driver.GridFS;
static void Main(string[] args)
        {
            string mongoUrl = "mongodb://192.168.0.226:6111/?socketTimeout=1s";
 MongoServerSettings setting = MongoServerSettings.FromUrl(MongoUrl.Create(mongoUrl));

            MongoServer server = new MongoServer(setting);

            MongoGridFSSettings settting2 = new MongoGridFSSettings();

            MongoGridFS fs = new MongoGridFS(server, "StudentDB", settting2);

            MongoGridFSFileInfo fi = fs.Upload("c:\test.doc", "中文测试.doc");

            byte[] buffer = new byte[1024];
            using (MongoGridFSStream readStream = fs.OpenRead("中文测试.doc"))
            {
                FileStream writeStream = new FileStream("c:\20160601.doc", FileMode.OpenOrCreate);
                int length = readStream.Read(buffer,0,buffer.Length);
                while(length>0)
                {
                    writeStream.Write(buffer, 0, length);
                    length = readStream.Read(buffer,0,buffer.Length);
                }
            }

db.getCollection('fs.files').find({})

db.getCollection('fs.chunks').find({})

写入成功后，文件保存在files及chunks两个集合

db.createUser( { user: "psuser",
                 pwd: "tydbadmin", 
                 roles: [ { role: "readWrite", db: "gps_current_ps" },
                          { role: "readWrite", db: "ob_active_ps" },
                            { role: "readWrite", db: "StudentDB" },
                            { role: "dbAdmin", db: "gps_current_ps" },
                            { role: "dbAdmin", db: "ob_active_ps" },
                            { role: "dbAdmin", db: "StudentDB" },
                          ]} )


db.auth( {
   user: "psuser",
   pwd: "tydbadmin", 
} )   



db.auth( {
   user: "admin",
   pwd: "admin123", 
} )   


db.collection.createIndex( {ObjID:1, Date: 1 } )
db.collection.createIndex( {Date: 1 } )

db.collection.createIndex( { orderDate: 1 } )
