CMD下运行以下命令: net stop 服务名 net start 服务名 备注:服务名 通常默认为:mysql 即: net stop mysql net start mysql 备注: 查看服务名的方式: 在桌面-右键计算机-选择管理-选择服务和应用程序-服务: 在服务到找到名称与Mysql相应的,一般情况
CMD下运行以下命令:
net stop
net start
备注: 通常默认为:mysql
即:
net stop mysql
net start mysql
备注:
查看服务名的方式:
在桌面->右键“计算机“->选择"管理”->选择”服务和应用程序“->”服务": 在服务到找到名称与Mysql相应的,一般情况下应该就是Mysql Server的服务名了。如Mysql56等。
想要关闭与打开服务,一般情况下要求cmd是“以管理员的形式打开的”
在Windows系统下,,对mysql的my.ini的log-bin等进行配置目录位置时,假设要将log-bin的日志配置到D盘的mysqllog的文件为binlog。则可以如下配置 :
[mysqld]
log-bin="D:mysqllog/binlog" 注意:在这里的最后一个路径采用的是"/"而不是Windows文件系统的“"

Optimizing MySQLBLOB requests can be done through the following strategies: 1. Reduce the frequency of BLOB query, use independent requests or delay loading; 2. Select the appropriate BLOB type (such as TINYBLOB); 3. Separate the BLOB data into separate tables; 4. Compress the BLOB data at the application layer; 5. Index the BLOB metadata. These methods can effectively improve performance by combining monitoring, caching and data sharding in actual applications.

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.
