HomeDatabaseMysql TutorialMySQL的安装过程_MySQL



最近对MySQL做了一些研究。以前主要接触的是SQL SERVER。所以,今天对该安装过程做了一些总结以及使用过程中的一些心得,并分享给大家。记得前面,分享过一篇关于数据库的几种连接方式。而本系列文章,将以对数据库的具体操作为主。

MySQL是最流行的开源SQL数据库管理系统,其由Oracle开发,部署和提供支持。MySQL官网http://www.mysql.com/提供了该软件的最新信息。MySQL是关系型数据库的管理系统,MySQLSERVER可以工作在Client/server 或嵌入式系统中。Oracle提供了一系列的MySQL的二进制部署文件,并压缩为tar格式,我们可以找到具体的对应版本。

具体步骤:

1 在下面的连接处下载文件。

http://dev.mysql.com/downloads/

2 我下载的是MySQL 5.7版本

选择安装方式。点击安装,根据提示,一步一步往下,会出现下面的安装界面:(选择自己需要的)

\

3 安装之后会要求配置,请一定选择好端口,避免端口冲突。默认端口是3306,我使用的是默认端口。

【在dos环境下,可以使用netstat命令来查看哪些端口正在使用】

\

4 账户和角色(很重要 ,一定要根据自己设置的来,最好备份下来)

填写 root账户对应的密码(请记住,后面要用,你登录也要用)

 

5 其余的按需要配置吧!

 

6找到mysqld服务器的位置(默认的在c盘下去找),输入如下命令,首次测试服务器:

(请将目录切换到安装目录,再输入)

mysqld.exe –console

会看到一些关于启动的消息。

7 mysql 安装验证

成功安装完 MySQL 后,就会初始化基表,启动服务器。可以通过一些简单的测试来验证安装是否一切正常。

使用 mysqladmin工具来获取服务器状态

输入命令:

mysqladmin --version

(我的测试输出如下:

mysqladmin Ver 8.42 Distrib 5.7.7-rc, for Win32 on AMD64)

使用mysql客户端来执行简单的SQL命令

你可以通过在MySQL客户端上使用 mysql 命令去连接 MySQL 服务器。这时,不需要输入任何密码,因为默认情况下会设置为空白。

【只限在初始状况下】

输入如下命令:

Mysql

 

8在控制台,输入命令:

mysql -u root –p

 

出现:Enter password: ***** 输入密码【rootpassword,前面叫记住的】

 

我的输出结果:(提示命令必须以;或\g结束)

Welcome to the MySQL monitor. Commands end with ; or \g.

Your MySQL connection id is 5

Type 'help;' or '\h' for help. Type '\c' toclear the current input statement.

 

9启动时运行mysql

如果想让 MySQL 在系统启动时自动运行,则可以 /etc/rc.local 文件中加入下列项:

/etc/init.d/mysqldstart

另外,在 etc/init.d/ 目录中必须存在mysqld 工具。

Explain the InnoDB Buffer Pool and its importance for performance.Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

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.
