安裝MongoDB的方法有很多種，可以源代碼安裝，在Centos也可以用yum源安裝的方法。

1、準備工作

運行yum命令查看MongoDB的包信息（正常是沒有信息提示的，我這里已經按安裝好了）

[root@localhost~]# yum info mongodb-org Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile Installed Packages Name : mongodb-org Arch : x86_64 Version : 3.4.10 Release : 1.el6 Size : 0.0 Repo : installed From repo : mongodb-org-3.4 Summary : MongoDB open source document-oriented database system (metapackage) URL : http://www.mongodb.org License : AGPL 3.0 Description : MongoDB is built for scalability, performance and high availability, scaling from single server deployments to large, complex multi-site architectures. By leveraging in-memory: computing, MongoDB provides high performance for both reads and writes. MongoDB’s native replication and automated failover enable enterprise-grade reliability and operational: flexibility.: : MongoDB is an open-source database used by companies of all sizes, across all industries and for a wide variety of applications. It is an agile database that allows schemas to: change quickly as applications evolve, while still providing the functionality developers expect from traditional databases, such as secondary indexes, a full query language: and strict consistency.: : MongoDB has a rich client ecosystem including hadoop integration, officially supported drivers for 10 programming languages and environments, as well as 40 drivers supported: by the user community.: : MongoDB features:: * JSON Data Model with Dynamic Schemas: * Auto-Sharding for Horizontal Scalability: * Built-In Replication for High Availability: * Rich Secondary Indexes, including geospatial: * TTL indexes: * Text Search: * Aggregation Framework & Native MapReduce: : This metapackage will install the mongo shell, import/export tools, other client utilities, server software, default configuration, and init.d scripts.

（如果沒有提示相關匹配的信息，） 說明你的centos系統中的yum源不包含MongoDB的相關資源，

2、增加源

vim /etc/yum.repos.d/mongodb-3.4.repo

輸入下面的語句：

[mongodb-org-3.4] name=MongoDB Repository baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.4/x86_64/ gpgcheck=1 enabled=1 gpgkey=https://www.mongodb.org/static/pgp/server-3.2.asc

3、安裝

yum install -y mongodb-org

4、啟動Mongodb

service mongod start

以后有更新了執行yum update??mongodb-org?即可。

5、服務器配置

# mongod.conf#where to log logpath=/data/logs/mongodb/mongod.loglogappend=true #以追加方式寫入日志# fork and run in background fork=true#port=27017dbpath=/data/mongo #數據庫文件保存位置# location of pidfile pidfilepath=/var/run/mongodb/mongod.pid# Listen to local interface only.

配置授權登錄

> use admin > db.createUser({user:"root",pwd:"123456",roles:[{role:"root",db:"admin"}]})

登錄數據庫

mongo 127.0.0.1:27017/admin -u root -p

查詢

> db.comlogs.find().count() 326466

PHP測試代碼

<?php $mongo = new Mongo("mongodb://root:123456@127.0.0.1:27017/admin"); //認證用戶，這里的數據庫，只啟認證作用 $db = $mongo->selectDB('admin'); //選取數據庫 $users= $db->selectCollection("test"); $cursor = $users->find(); foreach ($cursor as $id => $value) { echo "$id: "; print_r($value); echo "<br>"; } $document = array( "title" => "MongoDB", "description" => "database", "likes" => 100,"url" => "http://www.cnblogs.com/chenpingzhao" );$users->insert($document);

6、mongodb角色

內置角色

• 數據庫用戶角色：read、readWrite;

• 數據庫管理角色：dbAdmin、dbOwner、userAdmin；

• 集群管理角色：clusterAdmin、clusterManager、clusterMonitor、hostManager；

• 備份恢復角色：backup、restore；

• 所有數據庫角色：readAnyDatabase、readWriteAnyDatabase、userAdminAnyDatabase、dbAdminAnyDatabase

• 超級用戶角色：root， 這里還有幾個角色間接或直接提供了系統超級用戶的訪問（dbOwner 、userAdmin、userAdminAnyDatabase）

• 內部角色：__system

具體角色

• read：允許用戶讀取指定數據庫

• readWrite：允許用戶讀寫指定數據庫

• dbAdmin：允許用戶在指定數據庫中執行管理函數，如索引創建、刪除，查看統計或訪問system.profile

• userAdmin：允許用戶向system.users集合寫入，可以找指定數據庫里創建、刪除和管理用戶

• clusterAdmin：只在admin數據庫中可用，賦予用戶所有分片和復制集相關函數的管理權限。

• readAnyDatabase：只在admin數據庫中可用，賦予用戶所有數據庫的讀權限

• readWriteAnyDatabase：只在admin數據庫中可用，賦予用戶所有數據庫的讀寫權限

• userAdminAnyDatabase：只在admin數據庫中可用，賦予用戶所有數據庫的userAdmin權限

• dbAdminAnyDatabase：只在admin數據庫中可用，賦予用戶所有數據庫的dbAdmin權限。

• root：只在admin數據庫中可用。超級賬號，超級權限
