bitsCN.com fedora 16下mysql(rpm)安装使用手册lychee 安装Mysql 1、下载MySQL的安装文件 安装MySQL需要下面两个文件:MySQL-client-5.1.55-1.glibc23.i386.rpmMySQL-server-5.1.55-1.glibc23.i386.rpm下载地址为:http://mirrors.sohu.com/mysql/MySQL-5.1/可以使用: yum install mysql-server 进行安装 2、安装MySQLrpm文件是Red Hat公司开发的软件安装包,rpm可让Linux在安装软件包时免除许多复杂的手续。该命令在安装时常用的参数是 –ivh ,其中i表示将安装指定的rmp软件包,V表示安装时的详细信息,h表示在安装期间出现“#”符号来显示目前的安装过程。这个符号将持续到安装完成后才停 止。1)安装服务器端 在有两个rmp文件的目录下运行如下命令: [root@test1 local]# rpm -ivh MySQL-server-5.1.55-1.glibc23.i386.rpm提醒:如果出现如下error: Failed dependencies: perl(DBI) is needed by MySQL-server-5.1.16-0.glibc23.i386请使用yum install perl-DBI安装一下即可,当然这要试不同的发行版而言的。显示如下信息。 warning: MySQL-server-5.1.55-1.glibc23.i386.rpmsignature: NOKEY, key ID 5072e1f5 Preparing... ########################################### [100%]1:MySQL-server ########################################### [100%] 。。。。。。(省略显示) /usr/bin/mysqladmin -u root password 'new-password' /usr/bin/mysqladmin -u root -h test1 password 'new-password' 。。。。。。(省略显示) Starting mysqld daemon with databases from /var/lib/mysql 如出现如上信息,服务端安装完毕。测试是否成功可运行netstat看Mysql端口是否打开,如打开表示服务已经启动,安装成功。Mysql默认的端口是3306。 [root@test1 local]# netstat -nat Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 上面显示可以看出MySQL服务已经启动。 2)安装客户端 运行如下命令: [root@test1 local]# rpm -ivh MySQL-client-5.1.55-1.glibc23.i386.rpm warning: MySQL-client-5.1.55-1.glibc23.i386.rpm: V3 DSA signature: NOKEY, key ID 5072e1f5 Preparing... ########################################### [100%]1:MySQL-client ########################################### [100%] 显示安装完毕。 用下面的命令连接mysql,测试是否成功。三、登录MySQL 登录MySQL的命令是mysql, mysql 的使用语法如下: mysql [-u username] [-h host] [-p[password]] [dbname] username 与 password 分别是 MySQL 的用户名与密码,mysql的初始管理帐号是root,没有密码,注意:这个root用户不是Linux的系统用户。MySQL默认用户是root,由于 初始没有密码,第一次进时只需键入mysql即可。[root@test1 local]# mysql Welcome to the MySQL monitor. Commands end with ; or /g. Your MySQL connection id is 1 to server version: 4.0.16-standard Type 'help;' or '/h' for help. Type '/c' to clear the buffer. mysql> 出现了“mysql>”提示符,恭喜你,安装成功! 增加了密码后的登录格式如下: mysql -u root -p Enter password: (输入密码) 其中-u后跟的是用户名,-p要求输入密码,回车后在输入密码处输入密码。 注意:这个mysql文件在/usr/bin目录下,与后面讲的启动文件/etc/init.d/mysql不是一个文件。 Linux下MYSQL设置密码和访问数据库:设置mysql数据库密码 [root@localhost ~]#mysqladmin -u root password "密码"访问mysql数据库命令: [root@localhost ~]#mysql -u root -p → 敲回车 输入密码 mysql使用rpm安装使用默认信息如下:1)数据库目录 /var/lib/mysql/2)配置文件 /usr/share/mysql (mysql.server命令及配置文件 )3)相关命令 /usr/bin/ (mysqladmin mysqldump)4)启动脚本 /etc/rc.d/init.d/5)默认端口是3306 作者 jiangliqing1234 bitsCN.com

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.

MySQL and phpMyAdmin are powerful database management tools. 1) MySQL is used to create databases and tables, and to execute DML and SQL queries. 2) phpMyAdmin provides an intuitive interface for database management, table structure management, data operations and user permission management.

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.

I encountered a tricky problem when developing a small application: the need to quickly integrate a lightweight database operation library. After trying multiple libraries, I found that they either have too much functionality or are not very compatible. Eventually, I found minii/db, a simplified version based on Yii2 that solved my problem perfectly.

Article summary: This article provides detailed step-by-step instructions to guide readers on how to easily install the Laravel framework. Laravel is a powerful PHP framework that speeds up the development process of web applications. This tutorial covers the installation process from system requirements to configuring databases and setting up routing. By following these steps, readers can quickly and efficiently lay a solid foundation for their Laravel project.

When developing an e-commerce website using Thelia, I encountered a tricky problem: MySQL mode is not set properly, causing some features to not function properly. After some exploration, I found a module called TheliaMySQLModesChecker, which is able to automatically fix the MySQL pattern required by Thelia, completely solving my troubles.

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.
