通过rpm包安装、配置及卸载mysql的详细过程.
以MySQL-server-4.0.14-0.i386.rpm为例,放在/data目录下
cd /data
rpm -ivh MySQL-server-4.0.14-0.i386.rpm
安装完成后在/usr/share/mysql目录中会有一个mysql的启动脚本mysql.server及示例配置文件等(如my-huge.cnf、my-large.cnf、my-medium.cnf)
拷贝一个示例配置文件作为mysql的配置文件:
cp /usr/share/mysql/my-medium.cnf /etc/my.cnf
rpm包安装完后自动将mysql安装成系统服务,所以可以使用下面命令启动、停止mysql
启动mysql
/etc/init.d/mysql start 或 service mysql start
停止mysql
/etc/init.d/mysql stop 或 service mysql stop
到此,mysql服务就安装配置完成。
安装mysql客户端
rpm -ivh MySQL-client-4.0.14-0.i386.rpm
mysql安装好后目录结构如下:
工具程序在/usr/bin目录中---ls /usr/bin/mysql*
服务器程序/usr/sbin/mysqld
数据目录/var/lib/mysql
默认情况下mysql将错误日志文件、二进制日志文件及进程文件写在/var/lib/mysql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:
[mysqld_safe]
err-log = /var/log/mysqld.log
有个实用程序/usr/bin/mysql_install_db,该程序可以用来初始化mysql数据库教程,即创建/var/log/mysql目录,及创建mysql数据库(mysql授权表等信息)及test数据库(空库),如果不小心删除了/var/log/mysql目录可以通过该程序来初始化.
卸载mysql
rpm -qa|grep -i mysql
rpm -ev MySQL-server-4.0.14-0 MySQL-client-4.0.14-0
卸载后/var/lib/mysql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

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.

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

Apache connects to a database requires the following steps: Install the database driver. Configure the web.xml file to create a connection pool. Create a JDBC data source and specify the connection settings. Use the JDBC API to access the database from Java code, including getting connections, creating statements, binding parameters, executing queries or updates, and processing results.

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.

The process of starting MySQL in Docker consists of the following steps: Pull the MySQL image to create and start the container, set the root user password, and map the port verification connection Create the database and the user grants all permissions to the database

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.

Laravel is a PHP framework for easy building of web applications. It provides a range of powerful features including: Installation: Install the Laravel CLI globally with Composer and create applications in the project directory. Routing: Define the relationship between the URL and the handler in routes/web.php. View: Create a view in resources/views to render the application's interface. Database Integration: Provides out-of-the-box integration with databases such as MySQL and uses migration to create and modify tables. Model and Controller: The model represents the database entity and the controller processes HTTP requests.

The key to installing MySQL elegantly is to add the official MySQL repository. The specific steps are as follows: Download the MySQL official GPG key to prevent phishing attacks. Add MySQL repository file: rpm -Uvh https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm Update yum repository cache: yum update installation MySQL: yum install mysql-server startup MySQL service: systemctl start mysqld set up booting
