mysql设置密码的方法总结(linux/windows)
本文章总结了在linux与windows服务器中别分怎么设置mysql密码的方法,有需要的同学可参考一下。
windows下mysql
(适用于管理员或者有全局权限的用户重设其它用户的密码)
进入命令行模式
代码如下 | 复制代码 |
mysql -u root mysql mysql> UPDATE user SET password=PASSWORD("new password") WHERE user='name'; mysql> FLUSH PRIVILEGES; mysql> QUIT |
方法二:
(应用同上,只是方法不同)
代码如下 | 复制代码 |
mysql -u root mysql mysql> SET PASSWORD FOR name=PASSWORD('new password'); mysql> QUIT |
(以上两种方法我不常用,如果是管理员,我会用其它如phpmyadmin或者MYSQL-front 等工具来管理用户权限,比较直观又方便)
快速总结
代码如下 | 复制代码 |
a. ./mysqladmin -u root -p oldpassword newpasswd(记住这个命令是在/usr/local/mysql/bin中外部命令) b. SET PASSWORD FOR root=PASSWORD(’new password’);(对登录数据库后这种方式) c. UPDATE user SET password=PASSWORD(”new password”) WHERE user=’root’; (对登录数据库后这种方式) |
linux中mysql
MySQL如何设置root密码方法一:
最简单的方法,也是安装完mysql后,系统提示的方法。使用mysqladmin来完成。
代码如下 | 复制代码 |
shell> mysqladmin -u root password "newpwd" shell> mysqladmin -u root -h host_name password "newpwd"password |
后面的双引号不是必须的,不过如果密码包含空格或者一些特殊的符号,需要用引号。方法MySQL如何设置root密码二:利用mysql里面的SET PASSWORD命令来完成,注意必须使用PASSWORD()函数来加密设置的这个newpwd,否则直接='newpwd'不会生效。不过如果使用方法一用mysqladmin password设置密码或者用GRANT来设置,就不用使用PASSWORD()函数,因为它们已经自动调用了该函数。
代码如下 | 复制代码 |
shell> mysql -u root
mysql> SET PASSWORD FOR 'root'@'host_name' = PASSWORD('newpwd'); |
MySQL如何设置root密码方法三:
直接通过UPDATE user表来设置密码
代码如下 | 复制代码 |
shell> mysql -u root mysql> UPDATE mysql.user SET Password = PASSWORD('newpwd') -> WHERE User = 'root'; mysql> FLUSH PRIVILEGES; |
如果忘记mysql的root密码可以采取下面的步骤重新设置
1。kill掉所有mysql的进程
2。使用--skip-grant-tables的参数启动mysql
代码如下 | 复制代码 |
shell> mysqld_safe --skip-grant-tables & |
最后必杀技:
代码如下 | 复制代码 |
mysqladmin -u root "old password" "new password" |
解:以上有name的,请用你的用户名来替代.有new password请输入你想要设置的密码.

You can open phpMyAdmin through the following steps: 1. Log in to the website control panel; 2. Find and click the phpMyAdmin icon; 3. Enter MySQL credentials; 4. Click "Login".

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

Redis uses a single threaded architecture to provide high performance, simplicity, and consistency. It utilizes I/O multiplexing, event loops, non-blocking I/O, and shared memory to improve concurrency, but with limitations of concurrency limitations, single point of failure, and unsuitable for write-intensive workloads.

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

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

Effective monitoring of Redis databases is critical to maintaining optimal performance, identifying potential bottlenecks, and ensuring overall system reliability. Redis Exporter Service is a powerful utility designed to monitor Redis databases using Prometheus. This tutorial will guide you through the complete setup and configuration of Redis Exporter Service, ensuring you seamlessly build monitoring solutions. By studying this tutorial, you will achieve fully operational monitoring settings

The methods for viewing SQL database errors are: 1. View error messages directly; 2. Use SHOW ERRORS and SHOW WARNINGS commands; 3. Access the error log; 4. Use error codes to find the cause of the error; 5. Check the database connection and query syntax; 6. Use debugging tools.

Apache connects to a database requires the following steps: Install the database driver. Configure the web.xml file to create a connection pool. Create a JDBC data source and specify the connection settings. Use the JDBC API to access the database from Java code, including getting connections, creating statements, binding parameters, executing queries or updates, and processing results.
