m mongodb mongodb database

1、安装准备 [root@chen download]# tar zxvf mongodb-linux-x86_64-2.2.0.tgz [root@chen download]# cp mongodb-linux-x86_64-

1、安装准备

[root@chen download]# tar zxvf mongodb-linux-x86_64-2.2.0.tgz

[root@chen download]# cp mongodb-linux-x86_64-2.2.0 /usr/local/mongodb -r

2、创建数据库文件夹与日志文件

[root@chen download]# mkdir /usr/local/mongodb/data

[root@chen download]# touch /usr/local/mongodb/logs

设置开机自启动

将mongodb启动项目追加入rc.local保证mongodb在服务器开机时启动

[root@chen download]# echo "/usr/local/mongodb/bin/mongod --dbpath=/usr/local/mongodb/data –logpath=/usr/local/mongodb/logs –logappend        --auth –port=27017" >> /etc/rc.local

启动mongodb

cd到mongodb目录下的bin文件夹启动mongodb

//下面这个是需要权限的登录方式, 用户连接需要用户名和密码

[root@chen download]# /usr/local/mongodb/bin/mongod --dbpath=/usr/local/mongodb/data --logpath=/usr/local/mongodb/logs --logappend        --auth        --port=27017 --fork

//这个是不需要密码的

[root@chen download]# /usr/local/mongodb/bin/mongod --dbpath=/usr/local/mongodb/data --logpath=/usr/local/mongodb/logs --logappend        --port=27017 --fork

Use Composer to solve the dilemma of recommendation systems: andres-montanez/recommendations-bundle Use Composer to solve the dilemma of recommendation systems: andres-montanez/recommendations-bundle Apr 18, 2025 am 11:48 AM

When developing an e-commerce website, I encountered a difficult problem: how to provide users with personalized product recommendations. Initially, I tried some simple recommendation algorithms, but the results were not ideal, and user satisfaction was also affected. In order to improve the accuracy and efficiency of the recommendation system, I decided to adopt a more professional solution. Finally, I installed andres-montanez/recommendations-bundle through Composer, which not only solved my problem, but also greatly improved the performance of the recommendation system. You can learn composer through the following address:

MongoDB and relational database: a comprehensive comparison MongoDB and relational database: a comprehensive comparison Apr 08, 2025 pm 06:30 PM

MongoDB and relational database: In-depth comparison This article will explore in-depth the differences between NoSQL database MongoDB and traditional relational databases (such as MySQL and SQLServer). Relational databases use table structures of rows and columns to organize data, while MongoDB uses flexible document-oriented models to better suit the needs of modern applications. Mainly differentiates data structures: Relational databases use predefined schema tables to store data, and relationships between tables are established through primary keys and foreign keys; MongoDB uses JSON-like BSON documents to store them in a collection, and each document structure can be independently changed to achieve pattern-free design. Architectural design: Relational databases need to pre-defined fixed schema; MongoDB supports
