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

Server version: 5.7.7-rc-log MySQLCommunity Server (GPL)

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。

When might a full table scan be faster than using an index in MySQL? When might a full table scan be faster than using an index in MySQL? Apr 09, 2025 am 12:05 AM

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

Explain InnoDB Full-Text Search capabilities. Explain InnoDB Full-Text Search capabilities. Apr 02, 2025 pm 06:09 PM

InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.

Can I install mysql on Windows 7 Can I install mysql on Windows 7 Apr 08, 2025 pm 03:21 PM

Note the compatibility and security issues on Windows 7, and it is recommended to upgrade to a supported operating system.

Difference between clustered index and non-clustered index (secondary index) in InnoDB. Difference between clustered index and non-clustered index (secondary index) in InnoDB. Apr 02, 2025 pm 06:25 PM

The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values ​​and pointers to data rows, and is suitable for non-primary key column queries.

MySQL: Simple Concepts for Easy Learning MySQL: Simple Concepts for Easy Learning Apr 10, 2025 am 09:29 AM

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

The relationship between mysql user and database The relationship between mysql user and database Apr 08, 2025 pm 07:15 PM

In MySQL database, the relationship between the user and the database is defined by permissions and tables. The user has a username and password to access the database. Permissions are granted through the GRANT command, while the table is created by the CREATE TABLE command. To establish a relationship between a user and a database, you need to create a database, create a user, and then grant permissions.

Can mysql and mariadb coexist Can mysql and mariadb coexist Apr 08, 2025 pm 02:27 PM

MySQL and MariaDB can coexist, but need to be configured with caution. The key is to allocate different port numbers and data directories to each database, and adjust parameters such as memory allocation and cache size. Connection pooling, application configuration, and version differences also need to be considered and need to be carefully tested and planned to avoid pitfalls. Running two databases simultaneously can cause performance problems in situations where resources are limited.

Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial). Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial). Apr 02, 2025 pm 07:05 PM

MySQL supports four index types: B-Tree, Hash, Full-text, and Spatial. 1.B-Tree index is suitable for equal value search, range query and sorting. 2. Hash index is suitable for equal value searches, but does not support range query and sorting. 3. Full-text index is used for full-text search and is suitable for processing large amounts of text data. 4. Spatial index is used for geospatial data query and is suitable for GIS applications.
