以下的文章主要讲述的是MySQL 5 on Linux手动安装操作的具体方法,我们一共对其分成11部分,望你在浏览之后会对MySQL 5 on Linux手动安装操作有所收获,以下就是文章的具体操作内容。
1. MySQL 5 on Linux手动安装方法之一,
下载"MySQL(和PHP搭配之最佳组合)-standard-5.0.27-linux-i686-icc-glibc23.tar.gz",推荐ICC版本,据称比GCC性能提高10-20%
2. 复制到/usr/local/,解压:
tar zxvf MySQL(和PHP搭配之最佳组合)-standard-5.x....tar.gz
3. 添加用户和组MySQL(和PHP搭配之最佳组合):
groupadd MySQL(和PHP搭配之最佳组合)
useradd -g MySQL(和PHP搭配之最佳组合) MySQL(和PHP搭配之最佳组合)
4. 创建符号连接:
/usr/local # ln -s MySQL(和PHP搭配之最佳组合)-standard-5.x... MySQL(和PHP搭配之最佳组合)
5. cd MySQL(和PHP搭配之最佳组合),当前目录改为/usr/local/MySQL(和PHP搭配之最佳组合)/
6. 运行脚步初始化数据库:
./scripts/MySQL(和PHP搭配之最佳组合)_install_db --user=MySQL(和PHP搭配之最佳组合)
7. 设置权限:
/usr/local/MySQL(和PHP搭配之最佳组合) # chown -R root .
/usr/local/MySQL(和PHP搭配之最佳组合) # chown -R MySQL(和PHP搭配之最佳组合) data
/usr/local/MySQL(和PHP搭配之最佳组合) # chgrp -R MySQL(和PHP搭配之最佳组合)
8. MySQL 5 on Linux手动安装过程中根据需要创建并修改/etc/my.cnf,参考配置:
[MySQL(和PHP搭配之最佳组合)d]
# 设置默认为INNODB表,支持事务:
default-storage-engine=INNODB
# 设置默认的字符集:
default-character-set=utf8
# 禁用bdb:
http://www.knowsky.com
skip-bdb
9. 启动MySQL(和PHP搭配之最佳组合):
/usr/local/MySQL(和PHP搭配之最佳组合)/bin # ./MySQL(和PHP搭配之最佳组合)d_safe --user=MySQL(和PHP搭配之最佳组合) &
10. 初始化root口令:
/usr/local/MySQL(和PHP搭配之最佳组合)/bin # ./MySQL(和PHP搭配之最佳组合)admin -u root -p password "password-of-root"
Enter password:
11. 以root登录创建数据库:
/usr/local/MySQL(和PHP搭配之最佳组合) # ./MySQL(和PHP搭配之最佳组合) -u root -p
Enter password: password-of-root
创建一个新用户:
MySQL(和PHP搭配之最佳组合)> create user test identified by 'test-password';
创建一个新数据库:
MySQL(和PHP搭配之最佳组合)> create database testdb;
赋予test用户从localhost访问testdb的权限:
MySQL(和PHP搭配之最佳组合)> grant all on testdb.* to test@localhost;
停止MySQL(和PHP搭配之最佳组合)服务器:
/usr/local/MySQL(和PHP搭配之最佳组合)/bin # ./MySQL(和PHP搭配之最佳组合)admin -u root -p shutdown
Enter password: password-of-root
STOPPING server from pid file /usr/local/MySQL(和PHP搭配之最佳组合)/data/debian.pid
xxx MySQL(和PHP搭配之最佳组合)d ended

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

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 worth learning because it is a powerful open source database management system suitable for data storage, management and analysis. 1) MySQL is a relational database that uses SQL to operate data and is suitable for structured data management. 2) The SQL language is the key to interacting with MySQL and supports CRUD operations. 3) The working principle of MySQL includes client/server architecture, storage engine and query optimizer. 4) Basic usage includes creating databases and tables, and advanced usage involves joining tables using JOIN. 5) Common errors include syntax errors and permission issues, and debugging skills include checking syntax and using EXPLAIN commands. 6) Performance optimization involves the use of indexes, optimization of SQL statements and regular maintenance of databases.

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

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
