不记得 linux/windows中mysql root密码万能修改方法
本文章来介绍一下在linux和windows不记得root密码的修改方法,有碰到此类问题的同学可以参考一下本文章来修改你的密码。
如果本地忘记了root密码 ,可以试试以下方法:
打开CMD首先停止服务
net stop mysql
进入mysql安装目录下的bin文件夹,然后输入
mysqld-nt --skip-grant-tables
跳过密码检测
然后另外新打开一个cmd窗口
输入mysql 直接回车可以以root权限进入mysql
use mysql
update user set password=password("新密码") where user="root";
flush privileges;
如果无错误提示,密码 即可更改成功。
linux的处理办法
介绍一个在所有版本linux的grub上均可以使用的方法:
1、在Grub的引导装载程序菜单上,选择你要进入的条目,键入 “e” 来进入编辑模式;
2、在第二行(类似于kernel /vmlinuz-2.6.15 ro root=/dev/hda2 ),键入”e”进入编辑模式;
3、在句末加上”init=/bin/bash”,回车;
4、按“b”启动系统。
这样我们即可获得一个bash的shell,进入shell后,根分区的挂载模式默认是只读,我们要将其改为可写,否则不能更改root密码:
mount -no remount,rw /
passwd root
sync
mount -no remount,ro /
reboot
这样即可成功更改debian的root用户的密码

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.

InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.

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

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 suitable for small and large enterprises. 1) Small businesses can use MySQL for basic data management, such as storing customer information. 2) Large enterprises can use MySQL to process massive data and complex business logic to optimize query performance and transaction processing.

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.

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

MySQL is suitable for web applications and content management systems and is popular for its open source, high performance and ease of use. 1) Compared with PostgreSQL, MySQL performs better in simple queries and high concurrent read operations. 2) Compared with Oracle, MySQL is more popular among small and medium-sized enterprises because of its open source and low cost. 3) Compared with Microsoft SQL Server, MySQL is more suitable for cross-platform applications. 4) Unlike MongoDB, MySQL is more suitable for structured data and transaction processing.
