下面我们在CentOS 6.5 x64系统上安装最新的MongoDB 2.6.0二进制发行版。
1、下载MongoDB 2.6.0二进制发行版
$ curl -O
2、解压MongoDB的压缩包
$ tar zvxf mongodb-linux-x86_64-2.6.0.tgz
3、简化目录名
$ mv mongodb-linux-x86_64-2.6.0 mongodb
4、配置PATH环境变量
要确保MongoDB的bin目录包含在PATH环境变量中。
或者初级符号连接到/usr/local/bin目录。
$ sudo vi /etc/profile
添加下面的内容:
export PATH=$PATH:/home/chuser/mongodb/bin
让环境变量生效:
$ source /etc/profile
验证环境变量是否生效:
$ mongod -version
db version v2.6.0
2014-04-14T02:53:01.082+0000 git version: 1c1c76aeca21c5983dc178920f5052c298db616c
5、运行MongoDB
创建数据目录
$ mkdir -p mongodb/data/db
要确保mongod对数据目录有读写权限。
运行MongoDB(指定建立的数据目录)
$ mongod --dbpath /home/chuser/mongodb/data &
6、验证MongoDB是否正常运行
$ mongo
MongoDB shell version: 2.6.0
connecting to: test
2014-04-14T03:40:59.560+0000 [initandlisten] connection accepted from 127.0.0.1:39014 #1 (1 connection now open)

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.

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

MySQL is suitable for beginners because it is simple to install, powerful and easy to manage data. 1. Simple installation and configuration, suitable for a variety of operating systems. 2. Support basic operations such as creating databases and tables, inserting, querying, updating and deleting data. 3. Provide advanced functions such as JOIN operations and subqueries. 4. Performance can be improved through indexing, query optimization and table partitioning. 5. Support backup, recovery and security measures to ensure data security and consistency.

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.
