Centos下mongodb的安裝與配置

標籤：restore   horizon   from   tab   family   default   127.0.0.1   sharding   list   

安裝MongoDB的方法有很多種，可以原始碼安裝，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的包資訊（正常是沒有資訊提示的，我這裡已經按安裝好了）

[[email protected]~]# yum info mongodb-orgLoaded plugins: fastestmirrorLoading mirror speeds from cached hostfileInstalled PackagesName        : mongodb-orgArch        : x86_64Version     : 3.4.10Release     : 1.el6Size        : 0.0  Repo        : installedFrom repo   : mongodb-org-3.4Summary     : MongoDB open source document-oriented database system (metapackage)URL         : http://www.mongodb.orgLicense     : AGPL 3.0Description : 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資訊，） 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 Repositorybaseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.4/x86_64/gpgcheck=1enabled=1gpgkey=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

以後有更新了執行yum update  mongodb-org 即可。

5、伺服器配置

# mongod.conf#where to loglogpath=/data/logs/mongodb/mongod.loglogappend=true #以追加方式寫入日誌# fork and run in backgroundfork=true#port=27017dbpath=/data/mongo  #資料庫檔案儲存位置# location of pidfilepidfilepath=/var/run/mongodb/mongod.pid# Listen to local interface only.

配置授權登入

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

登入資料庫

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:[email protected]:27017/admin");   //認證使用者，這裡的資料庫，只啟認證作用  $db = $mongo->selectDB(‘admin‘);  //選取資料庫  $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

內建角色

• 資料庫使用者角色：read、readWrite;

• 資料庫管理角色：dbAdmin、dbOwner、userAdmin；

• 叢集管理角色：clusterAdmin、clusterManager、clusterMonitor、hostManager；

• 備份恢複角色：backup、restore；

• 所有資料庫角色：readAnyDatabase、readWriteAnyDatabase、userAdminAnyDatabase、dbAdminAnyDatabase

• 超級使用者角色：root， 這裡還有幾個角色間接或直接提供了系統超級使用者的訪問（dbOwner 、userAdmin、userAdminAnyDatabase）

• 內部角色：__system

具體角色

• read：允許使用者讀取指定資料庫

• readWrite：允許使用者讀寫指定資料庫

• dbAdmin：允許使用者在指定資料庫中執行管理函數，如索引建立、刪除，查看統計或訪問system.profile

• userAdmin：允許使用者向system.users集合寫入，可以找指定資料庫裡建立、刪除和系統管理使用者

• clusterAdmin：只在admin資料庫中可用，賦予使用者所有分區和複製集相關函數的系統管理權限。

• readAnyDatabase：只在admin資料庫中可用，賦予使用者所有資料庫的讀許可權

• readWriteAnyDatabase：只在admin資料庫中可用，賦予使用者所有資料庫的讀寫權限

• userAdminAnyDatabase：只在admin資料庫中可用，賦予使用者所有資料庫的userAdmin許可權

• dbAdminAnyDatabase：只在admin資料庫中可用，賦予使用者所有資料庫的dbAdmin許可權。

• root：只在admin資料庫中可用。超級帳號，超級許可權
