mysql卸载
bitsCN.com 下面的文章主要描述的是如何正确通过rpm包安装、对MySQL进行配置与卸载,以下就有详细内容对配置MySQL与卸载MySQL(和PHP搭配之最佳组合)的详细操作过程,希望会给你带来一些帮助在此方面。以MySQL(和PHP搭配之最佳组合)-server-4.0.14-0.i386.rpm为例,
放在/data目录下
cd /data
rpm -ivh MySQL(和PHP搭配之最佳组合)-server-4.0.14-0.i386.rpm
安装完成后在/usr/share/MySQL(和PHP搭配之最佳组合)目录中会有一个MySQL(和PHP搭配之最佳组合)的启动脚本MySQL(和PHP搭配之最佳组合).server及示例配置文件等(如my-huge.cnf、my-large.cnf、my-medium.cnf)
拷贝一个示例配置MySQL文件作为MySQL(和PHP搭配之最佳组合)的配置文件:
cp /usr/share/MySQL(和PHP搭配之最佳组合)/my-medium.cnf /etc/my.cnf
rpm包安装完后自动将MySQL(和PHP搭配之最佳组合)安装成系统服务,所以可以使用下面命令启动、停止MySQL(和PHP搭配之最佳组合)
启动MySQL(和PHP搭配之最佳组合)
/etc/init.d/MySQL(和PHP搭配之最佳组合) start 或 service MySQL(和PHP搭配之最佳组合) start
停止MySQL(和PHP搭配之最佳组合)
/etc/init.d/MySQL(和PHP搭配之最佳组合) stop 或 service MySQL(和PHP搭配之最佳组合) stop
到此,MySQL(和PHP搭配之最佳组合)服务就安装配置MySQL完成。
安装MySQL(和PHP搭配之最佳组合)客户端
rpm -ivh MySQL(和PHP搭配之最佳组合)-client-4.0.14-0.i386.rpm
MySQL(和PHP搭配之最佳组合)安装好后目录结构如下:
工具程序在/usr/bin目录中---ls /usr/bin/MySQL(和PHP搭配之最佳组合)*
服务器程序/usr/sbin/MySQL(和PHP搭配之最佳组合)d
数据目录/var/lib/MySQL(和PHP搭配之最佳组合)
默认情况下MySQL(和PHP搭配之最佳组合)将错误日志文件、二进制日志文件及进程文件写在/var/lib/MySQL(和PHP搭配之最佳组合)目录中,如localhost.err、localhost.pid、localhost-bin.001等
要改变这些情况可以修改/etc/my.cnf文件
如将日志文件写在/var/log目录中,可以在my.cnf文件中加入下面两行:
[MySQL(和PHP搭配之最佳组合)d_safe]
err-log = /var/log/MySQL(和PHP搭配之最佳组合)d.log
有个实用程序/usr/bin/MySQL(和PHP搭配之最佳组合)_install_db,该程序可以用来初始化MySQL(和PHP搭配之最佳组合)数据库,即创建/var/log/MySQL(和PHP搭配之最佳组合)目录,及创建MySQL(和PHP搭配之最佳组合)数据库(MySQL(和PHP搭配之最佳组合)授权表等信息)及test数据库(空库),如果不小心删除了/var/log/MySQL(和PHP搭配之最佳组合)目录可以通过该程序来初始化.
卸载MySQL(和PHP搭配之最佳组合)
rpm -qa|grep -i MySQL(和PHP搭配之最佳组合)
rpm -ev MySQL(和PHP搭配之最佳组合)-server-4.0.14-0 MySQL(和PHP搭配之最佳组合)-client-4.0.14-0
卸载后/var/lib/MySQL(和PHP搭配之最佳组合)中的数据及/etc/my.cnf不会删除,如果确定没用后就手工删除
rm -f /etc/my.cnf
rm -rf /var/lib/MySQL(和PHP搭配之最佳组合)
以上的相关内容就是对配置及卸载MySQL的介绍,望你能有所收获。bitsCN.com

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
