MongoDB是一个基于分布式文件存储的数据库。由C++语言编写。旨在为WEB应用提供可扩展的高性能数据存储解决方案。

介绍
MongoDB是一个基于分布式文件存储的数据库。由C++语言编写。旨在为WEB应用提供可扩展的高性能数据存储解决方案。
 
特点
高性能、易部署、易使用,存储数据非常方便。

主要功能特性有:

使用原理
所谓“面向集合”(Collenction-Oriented),意思是数据被分组存储在数据集中,被称为一个集合(Collenction)。每个集合在数据库中都有一个唯一的标识名,并且可以包含无限数目的文档。集合的概念类似关系型数据库(RDBMS)里的表(table),不同的是它不需要定义任何模式(schema)。
 
模式自由(schema-free),,意味着对于存储在mongodb数据库中的文件,我们不需要知道它的任何结构定义。如果需要的话,你完全可以把不同结构的文件存储在同一个数据库里。
 
存储在集合中的文档,被存储为键-值对的形式。键用于唯一标识一个文档,为字符串类型,而值则可以是各种复杂的文件类型。我们称这种存储形式为BSON(Binary JSON)。

准备
1. 下载安装文件。 

cd /tmp   
wget https://www.mongodb.org/dr//fastdl.mongodb.org/linux/mongodb-linux-x86_64-2.4.10.tgz/download
tar –zxvf download   
cd /tmp/mongodb-linux-x86_64-2.4.10/bin   
cp * /usr/bin/

 
安装
1. 创建启动用户mongod。 

12 groupadd mongod   
useradd –g mongod mongod

或   

useradd –M –s /sbin/nologin mongod

2. 创建数据库目录。 

#日志文件目录   
mkdir –p /data/var/log/mongodb/   
#数据文件目录   
mkdir –p /data/var/lib/mongodb/   
#PID文件目录   
mkdir –p /data/var/run/mongodb/

3. 修改目录所有者。 

cd /data/var   
chown –R mongod.mongod log lib run

配置
1. 创建配置文件/etc/mongod.conf。 

logpath=/data/var/log/mongodb/mongod.log   
logappend=true   
fork=true   
dbpath=/data/var/lib/mongodb   
journal=true   
directoryperdb = true   
auth = true   
#replSet = rs_test   
#keyFile = /etc/mongo_main.key

2. 若将配置为副本集成员,从另一台成员上拷贝文件。 

scp –P 22 /etc/mongod.conf [email protected]:/tmp   
scp –P 22 /etc/mongo_main.key [email protected]:/tmp   
cp /tmp/mongo_main.key /etc/   
cp /tmp/mongod.conf /etc/   
chown mongod.mongod /etc/mongo_main.key

3. 创建启动脚本mongod。 

scp –P 22 /etc/init.d/mongod [email protected]:/tmp   
cp /tmp/mongod /etc/init.d/mongod   
chkconfig –level 35 mongod on

4. 修改系统最大打开文件数。 

ulimit –n 64000   
vi /etc/security/limits.conf

在最后添加:   
* soft nofile 64000   
* hard nofile 64000   
* soft nproc 32000   
* hard nproc 32000
 

vi /etc/profile

在最后添加:   
ulimit –n 64000   
在启动脚本mongod中也增加ulimit –n 64000

5. 启动服务。

Explain InnoDB Full-Text Search capabilities. Explain InnoDB Full-Text Search capabilities. Apr 02, 2025 pm 06:09 PM

InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.

When might a full table scan be faster than using an index in MySQL? When might a full table scan be faster than using an index in MySQL? Apr 09, 2025 am 12:05 AM

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

Note the compatibility and security issues on Windows 7, and it is recommended to upgrade to a supported operating system.

Difference between clustered index and non-clustered index (secondary index) in InnoDB. Difference between clustered index and non-clustered index (secondary index) in InnoDB. Apr 02, 2025 pm 06:25 PM

The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values ​​and pointers to data rows, and is suitable for non-primary key column queries.

Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial). Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial). Apr 02, 2025 pm 07:05 PM

MySQL supports four index types: B-Tree, Hash, Full-text, and Spatial. 1.B-Tree index is suitable for equal value search, range query and sorting. 2. Hash index is suitable for equal value searches, but does not support range query and sorting. 3. Full-text index is used for full-text search and is suitable for processing large amounts of text data. 4. Spatial index is used for geospatial data query and is suitable for GIS applications.
