In the process of using the Linux operating system, we often encounter the situation of forgetting the MySQL password. What should we do at this time? This article will introduce several methods to solve this problem.
Method 1: Use mysqld_safe to start MySQL
- Stop the MySQL service: Use the following command to stop the MySQL service.
sudo /etc/init.d/mysql stop
- Start the MySQL service: Use the following command to start the MySQL service and add the --skip-grant-tables parameter after the command.
sudo mysqld_safe --skip-grant-tables &
- Access MySQL: Use the following command to access MySQL.
sudo mysql
- Change password: After entering MySQL, use the following command to change the password.
use mysql; update user set password=PASSWORD("new_password") where User='root'; flush privileges;
The "new_password" is the new password you want to set. After the setting is successful, you can use the quit command to exit MySQL, and then use the following command to restart the MySQL service.
sudo /etc/init.d/mysql restart
Method 2: Use the dpkg-reconfigure command
- Stop the MySQL service: Use the following command to stop the MySQL service.
sudo /etc/init.d/mysql stop
- Use the dpkg-reconfigure command: Use the following command to reset the MySQL password.
sudo dpkg-reconfigure mysql-server-5.5
The option to reset the MySQL password will appear.
- Restart the MySQL service: Use the following command to restart the MySQL service.
sudo /etc/init.d/mysql restart
It should be noted that the dpkg-reconfigure command is only valid on Debian systems.
Method 3: Use the MySQL management tool
In addition to the above two methods, you can also use the MySQL management tool to reset the MySQL password. Here are two commonly used MySQL management tools.
- phpMyAdmin: phpMyAdmin is a Web-based MySQL management tool. You can use a Web browser to manage MySQL databases through phpMyAdmin. First you need to install phpMyAdmin, use the following command to install it.
sudo apt-get install phpmyadmin
- MySQL Workbench: MySQL Workbench is a cross-platform MySQL database management tool. MySQL Workbench can be installed using the following command.
sudo apt-get install mysql-workbench
To use the MySQL management tool to reset the password, you need to provide the user name and password of the MySQL administrator. Before resetting your password, make sure you have backed up your MySQL database.
To sum up, forgetting MySQL password is not a troublesome problem and can be solved by the above methods. Before operating, be sure to back up the database to avoid losing important data.

How to effectively monitor MySQL performance? Use tools such as mysqladmin, SHOWGLOBALSTATUS, PerconaMonitoring and Management (PMM), and MySQL EnterpriseMonitor. 1. Use mysqladmin to view the number of connections. 2. Use SHOWGLOBALSTATUS to view the query number. 3.PMM provides detailed performance data and graphical interface. 4.MySQLEnterpriseMonitor provides rich monitoring functions and alarm mechanisms.

The difference between MySQL and SQLServer is: 1) MySQL is open source and suitable for web and embedded systems, 2) SQLServer is a commercial product of Microsoft and is suitable for enterprise-level applications. There are significant differences between the two in storage engine, performance optimization and application scenarios. When choosing, you need to consider project size and future scalability.

In enterprise-level application scenarios that require high availability, advanced security and good integration, SQLServer should be chosen instead of MySQL. 1) SQLServer provides enterprise-level features such as high availability and advanced security. 2) It is closely integrated with Microsoft ecosystems such as VisualStudio and PowerBI. 3) SQLServer performs excellent in performance optimization and supports memory-optimized tables and column storage indexes.

A MySQL trigger is an automatically executed stored procedure associated with a table that is used to perform a series of operations when a specific data operation is performed. 1) Trigger definition and function: used for data verification, logging, etc. 2) Working principle: It is divided into BEFORE and AFTER, and supports row-level triggering. 3) Example of use: Can be used to record salary changes or update inventory. 4) Debugging skills: Use SHOWTRIGGERS and SHOWCREATETRIGGER commands. 5) Performance optimization: Avoid complex operations, use indexes, and manage transactions.

The steps to create and manage user accounts in MySQL are as follows: 1. Create a user: Use CREATEUSER'newuser'@'localhost'IDENTIFIEDBY'password'; 2. Assign permissions: Use GRANTSELECT, INSERT, UPDATEONmydatabase.TO'newuser'@'localhost'; 3. Fix permission error: Use REVOKEALLPRIVILEGESONmydatabase.FROM'newuser'@'localhost'; then reassign permissions; 4. Optimization permissions: Use SHOWGRA

MySQL is suitable for rapid development and small and medium-sized applications, while Oracle is suitable for large enterprises and high availability needs. 1) MySQL is open source and easy to use, suitable for web applications and small and medium-sized enterprises. 2) Oracle is powerful and suitable for large enterprises and government agencies. 3) MySQL supports a variety of storage engines, and Oracle provides rich enterprise-level functions.

The disadvantages of MySQL compared to other relational databases include: 1. Performance issues: You may encounter bottlenecks when processing large-scale data, and PostgreSQL performs better in complex queries and big data processing. 2. Scalability: The horizontal scaling ability is not as good as Google Spanner and Amazon Aurora. 3. Functional limitations: Not as good as PostgreSQL and Oracle in advanced functions, some functions require more custom code and maintenance.
