Ubuntu 12.04 下安装MySQL 5.5.25
Ubuntu 12.04 下安装MySQL 5.5.25,下载相应的MySQL版本(本文选择的是64位tar压缩版本),创建mysql用户和组。注意,我们创建的
Ubuntu版本:12.04 LTS
MySQL版本:MySQL Community Server 5.5.25
安装目录:/usr/local/development/mysql-5.5.25
1. 打开网址,下载相应的MySQL版本(本文选择的是64位tar压缩版本)。
2. 将下载的文件解压缩到/usr/local/development/mysql-5.5.25目录。
3. 创建mysql用户和组。注意,我们创建的mysql用户只是为了控制文件所有权的目的,因此我们执行useradd的时候使用了-r参数让它不需要登陆。
sudo groupadd mysql sudo useradd -r -g mysql mysql
4. 改变/usr/local/development/mysql-5.5.25目录的所有者为mysql。
sudo chown -R mysql:mysql /usr/local/development/mysql-5.5.25/
5. 使用mysql_install_db初始化授权表。此操作只是在MySQL初次安装时才需要执行,如果是已存在的安装,,则可以跳过此步骤,否则会覆盖先前的授权信息。
sudo scripts/mysql_install_db --user=mysql
6. 发现mysql_install_db执行有错误。看错误提示,原来是因为缺少共享库libaio1。
7. 安装共享库libaio1。

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.

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

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

MySQL is suitable for small and large enterprises. 1) Small businesses can use MySQL for basic data management, such as storing customer information. 2) Large enterprises can use MySQL to process massive data and complex business logic to optimize query performance and transaction processing.

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA

MySQL is suitable for web applications and content management systems and is popular for its open source, high performance and ease of use. 1) Compared with PostgreSQL, MySQL performs better in simple queries and high concurrent read operations. 2) Compared with Oracle, MySQL is more popular among small and medium-sized enterprises because of its open source and low cost. 3) Compared with Microsoft SQL Server, MySQL is more suitable for cross-platform applications. 4) Unlike MongoDB, MySQL is more suitable for structured data and transaction processing.
