Installation and configuration of MongoDB under CentOS

There are many ways to install MongoDB, you can install the source code, and you can use the Yum source installation method in CentOS.

1. Preparatory work

Run the Yum command to view the MongoDB package information (normal is no information prompted, I have already pressed the installation here)

[[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 sy Stem (metapackage) URL:HTTP://WWW.MONGODB.ORGLICENSE:AGPL 3.0description:mongodb is built for scalability , performance and availability, scaling from single server deployments to large, complex multi-site architectures.

(If there is no indication of the relevant matching information,) the Yum source in your CentOS system does not contain MONGODB related resources,

2. Increase the source

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

Enter the following statement:

[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. Installation

Yum Install-y mongodb-org

4. Start MongoDB

Service Mongod Start

There is a later update to perform yum update mongodb-org .

5. Server Configuration

PHP test Code

<?php$mongo = new MONGO ("Mongodb://root:[email protected]:27017/admin");   Authenticated Users, the database here, only the authentication function  $db = $mongo->selectdb (' admin ');  Select database  $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" = "=", "    url" = > "Http://www.cnblogs.com/chenpingzhao"); $users->insert ($document);
