mongodb数据库教程-MongoDB安装配置(Windows)

跨零代码为大家提供高品质的解决方案,请大家多多来访,跨零不胜感激,在此谢过。

要在Windows上安装 MongoDB,首先打开: http://www.mongodb.org/downloads 下载最新版本的MongoDB。确保根据您的Windows版本获得正确版本的MongoDB。要获取 Windows 版本,请打开命令提示符并执行以下命令。

C:/Users/Administrator> wmic os get osarchitecture OSArchitecture 64 位 

如上所示,这里 Windows 版本是 64位的操作系统,所以下载对应的 MongoDB-for-Windows 64位版本,如下图所示 –

前提条件

MongoDB社区版需要Windows Server 2008 R2,Windows Vista或更高版本(注:本教程将演示在Windows10 46位系统上安装MongoDB)。 .msi安装程序包括所有其他软件相关性,并将自动升级任何使用.msi文件安装的旧版本的 MongoDB。

MongoDB安装

在Windows资源管理器中,找到下载的MongoDB.msi文件,通常位于默认的“下载”文件夹中。 双击mongodb-win32-x86_64-2008plus-ssl-3.4.5-signed.msi文件。 将出现一组屏幕,指导您完成安装过程。

MongoDB安装配置(Windows)

运行MongoDB

MongoDB需要一个数据目录来存储所有数据。MongoDB的默认数据目录路径是从中启动 MongoDB 的驱动器上的绝对路径D:/Program Files/MongoDB/Server/3.4/data/db。通过在命令提示符中运行以下命令来创建此文件夹:

D:/Program Files/MongoDB/Server/3.4> "md D:/Program Files/MongoDB/Server/3.4/data" 

可以使用--dbpath选项为mongod.exe指定数据文件的备用路径,例如:

“D:/Program Files/MongoDB/Server/3.4/bin/mongod.exe" --dbpath "D:/Program Files/MongoDB/Server/3.4/data/db" 

启动MongoDB

要启动 MongoDB,请运行 mongod.exe 。 例如,从命令提示符:

“D:/Program Files/MongoDB/Server/3.4/bin/mongod.exe" 

在执行上面命令启动后,应该会看到类似下面的输出结果 –

打开 MongoDB 客户端测试使用

D:/Program Files/MongoDB/Server/3.4/bin> mongo.exe MongoDB shell version v3.4.5 connecting to: mongodb://127.0.0.1:27017 MongoDB server version: 3.4.5 Welcome to the MongoDB shell.

MongoDB帮助

要获取命令列表,请在MongoDB客户端中键入:db.help()。 这将列出一个命令列表,如下面的屏幕截图所示 –

> db.help() DB methods:         db.adminCommand(nameOrDocument) - switches to 'admin' db, and runs command [ just calls db.runCommand(...) ]         db.auth(username, password)         db.cloneDatabase(fromhost)         db.commandHelp(name) returns the help for the command         db.copyDatabase(fromdb, todb, fromhost)         db.createCollection(name, { size : ..., capped : ..., max : ... } )         db.createView(name, viewOn, [ { $operator: {...}}, ... ], { viewOptions } )         db.createUser(userDocument)         db.currentOp() displays currently executing operations in the db         db.dropDatabase()         db.eval() - deprecated         db.fsyncLock() flush data to disk and lock server for backups         db.fsyncUnlock() unlocks server following a db.fsyncLock()         db.getCollection(cname) same as db['cname'] or db.cname         db.getCollectionInfos([filter]) - returns a list that contains the names and options of the db's collections         db.getCollectionNames()         db.getLastError() - just returns the err msg string         db.getLastErrorObj() - return full status object         db.getLogComponents()         db.getMongo() get the server connection object         db.getMongo().setSlaveOk() allow queries on a replication slave server         db.getName()         db.getPrevError()         db.getProfilingLevel() - deprecated         db.getProfilingStatus() - returns if profiling is on and slow threshold         db.getReplicationInfo()         db.getSiblingDB(name) get the db at the same server as this one         db.getWriteConcern() - returns the write concern used for any operations on this db, inherited from server object if set         db.hostInfo() get details about the server's host         db.isMaster() check replica primary status         db.killOp(opid) kills the current operation in the db         db.listCommands() lists all the db commands         db.loadServerScripts() loads all the scripts in db.system.js         db.logout()         db.printCollectionStats()         db.printReplicationInfo()         db.printShardingStatus()         db.printSlaveReplicationInfo()         db.dropUser(username)         db.repairDatabase()         db.resetError()         db.runCommand(cmdObj) run a database command.  if cmdObj is a string, turns it into { cmdObj : 1 }         db.serverStatus()         db.setLogLevel(level,<component>)         db.setProfilingLevel(level,<slowms>) 0=off 1=slow 2=all         db.setWriteConcern( <write concern doc> ) - sets the write concern for writes to the db         db.unsetWriteConcern( <write concern doc> ) - unsets the write concern for writes to the db         db.setVerboseShell(flag) display extra information in shell output         db.shutdownServer()         db.stats()         db.version() current version of the server > 

MongoDB统计

要获取有关MongoDB服务器的统计信息,请在 MongoDB 客户端中键入命令:db.stats()。 这个命令将显示数据库名称,数据库中的集合和文档数量。命令的输出如下面的截图所示 –

> db.stats() {         "db" : "test",         "collections" : 0,         "views" : 0,         "objects" : 0,         "avgObjSize" : 0,         "dataSize" : 0,         "storageSize" : 0,         "numExtents" : 0,         "indexes" : 0,         "indexSize" : 0,         "fileSize" : 0,         "ok" : 1 } >
