MYSQL 修改root密码命令小结,需要的朋友可以参考下。
一、请问在win2K命令提示符下怎样更改mysql的root管理员密码?>mysql -u root -p
Enter password: ******
mysql> use mysql;
mysql> update user set password=password('new_password') where user='root';
通过这种方法就可以直接修改密码了。至于在CMD下能否登陆MySQL,就要在Windows环境变量PATH中添加“C:\Program Files\MySQL\MySQL Server 5.0\bin;”(请改为你自己的安装路径)了。
二、MYSQL 修改root密码命令
cmd下切换到 mysql 安装目录
例
d:/mysql/bin
前提:mysql用户root密码为空.
输入 mysql -u root mysql
mysql> 状态下输入 update user set password=password('新密码') where user='root';
回显
Query OK, 0 rows affected (0.00 sec)
Rows matched: 2 Changed: 0 Warnings: 0
mysql> 状态下输入 FLUSH PRIVILEGES;
回显
Query OK, 0 rows affected (0.00 sec)
mysql> 状态下输入 quit
退出 sql
注意每个命令后都要加上一个分号 ";"
mysql 才开始执行该行命令
而第二个指令会让已载入记忆体的 mysql 系统资料库更新
重起 mysql .
停止MYSQL
net stop mysql
开始MYSQL
net start mysql

Mastering the method of adding MySQL users is crucial for database administrators and developers because it ensures the security and access control of the database. 1) Create a new user using the CREATEUSER command, 2) Assign permissions through the GRANT command, 3) Use FLUSHPRIVILEGES to ensure permissions take effect, 4) Regularly audit and clean user accounts to maintain performance and security.

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.

When selecting MySQL's BLOB and TEXT data types, BLOB is suitable for storing binary data, and TEXT is suitable for storing text data. 1) BLOB is suitable for binary data such as pictures and audio, 2) TEXT is suitable for text data such as articles and comments. When choosing, data properties and performance optimization must be considered.
