文章要介绍关于忘记mysql的root密码重置方法,同时介绍了在不同的操作系统,下面介绍了在linux和windows中的解决办法,有需要了朋友可以了解一下。
如果忘记了 MySQL 的 root 密码,可以用以下方法重新设置:
linux操作方法
在my.cnf的[d]字段加入:
代码如下 | 复制代码 |
skip-grant-tables |
然后重启你的mysqld,这样久没有密码了.
然后进入mysql。
代码如下 | 复制代码 |
UPDATE mysql.user SET Password=PASSWORD |
成功后
代码如下 | 复制代码 |
FLUSH PRIVILEGES; |
最后去掉my.cnf中的skip-grant-tables
重启mysqld。
windows操作方法
1. KILL掉系统里的MySQL进程;
2. 用以下命令启动MySQL,以不检查权限的方式启动;
代码如下 | 复制代码 |
mysqld_safe -skip-grant-tables & |
3. 然后用空密码方式使用root用户登录 MySQL;
代码如下 | 复制代码 |
mysql -u root |
4. 修改root用户的密码;
代码如下 | 复制代码 |
mysql> update mysql.user set password=PASSWORD(’新密码’) where User=’root’; mysql> flush privileges; mysql> quit |
5. 重新启动MySQL,就可以使用新密码登录了。

MySQL processes data replication through three modes: asynchronous, semi-synchronous and group replication. 1) Asynchronous replication performance is high but data may be lost. 2) Semi-synchronous replication improves data security but increases latency. 3) Group replication supports multi-master replication and failover, suitable for high availability requirements.

The EXPLAIN statement can be used to analyze and improve SQL query performance. 1. Execute the EXPLAIN statement to view the query plan. 2. Analyze the output results, pay attention to access type, index usage and JOIN order. 3. Create or adjust indexes based on the analysis results, optimize JOIN operations, and avoid full table scanning to improve query efficiency.

Using mysqldump for logical backup and MySQLEnterpriseBackup for hot backup are effective ways to back up MySQL databases. 1. Use mysqldump to back up the database: mysqldump-uroot-pmydatabase>mydatabase_backup.sql. 2. Use MySQLEnterpriseBackup for hot backup: mysqlbackup--user=root-password=password--backup-dir=/path/to/backupbackup. When recovering, use the corresponding life

The main reasons for slow MySQL query include missing or improper use of indexes, query complexity, excessive data volume and insufficient hardware resources. Optimization suggestions include: 1. Create appropriate indexes; 2. Optimize query statements; 3. Use table partitioning technology; 4. Appropriately upgrade hardware.

MySQL view is a virtual table based on SQL query results and does not store data. 1) Views simplify complex queries, 2) Enhance data security, and 3) Maintain data consistency. Views are stored queries in databases that can be used like tables, but data is generated dynamically.

MySQL partitioning improves performance and simplifies maintenance. 1) Divide large tables into small pieces by specific criteria (such as date ranges), 2) physically divide data into independent files, 3) MySQL can focus on related partitions when querying, 4) Query optimizer can skip unrelated partitions, 5) Choosing the right partition strategy and maintaining it regularly is key.

How to grant and revoke permissions in MySQL? 1. Use the GRANT statement to grant permissions, such as GRANTALLPRIVILEGESONdatabase_name.TO'username'@'host'; 2. Use the REVOKE statement to revoke permissions, such as REVOKEALLPRIVILEGESONdatabase_name.FROM'username'@'host' to ensure timely communication of permission changes.
