mysql的默认编码是拉丁,每次JSP制作网页用insert语句插入数据库时汉字都会显示成问号,安装mysql后,启动服务并登陆,使用show variables命令可查看mysql数据库的默认编码:
由上图可见database和server的字符集使用了latin1编码方式,不支持中文,即存储中文时会出现乱码。以下是命令行修改为utf-8编码的过程,以支持中文。
(1)关闭mysql服务
[plain] view plaincopy
service mysql stop
(2)修改 /etc/mysql/my.cnf (默认的安装路径)
[plain] view plaincopy
vim /etc/mysql/my.cnf
打开my.cnf后,在文件内的[mysqld]下增加如下两行设置:
[plain] view plaincopy
character_set_server=utf8
init_connect='SET NAMES utf8'
(具体如截图所示):
保存退出。
(3) 重新启动mysql服务
[plain] view plaincopy
service mysql start
至此,完成修改默认编码,登陆mysql后重新使用show variable like '%character%'获得的输出效果如下:
注
具体操作和输出情况如下:
解决方法:打开mysql安装目录:C:Program FilesMySQLMysql server5.5
打开文件my.ini配置文件,找到 default-character-set=latin1 并改为:
default-character-set=gbk,找到 character-set-server=latin1 并改为:
character-set-server=gbk,修改完之后保存。
最后:我的电脑右击 “管理”进入之后选择“服务和应用程序”下的“服务”
找到“mysql”之后右击选择“重新启动”。
把jsp页面中的odin g="ISO-8859-1"%>改为

Common security vulnerabilities in MySQL include SQL injection, weak passwords, improper permission configuration, and unupdated software. 1. SQL injection can be prevented by using preprocessing statements. 2. Weak passwords can be avoided by forcibly using strong password strategies. 3. Improper permission configuration can be resolved through regular review and adjustment of user permissions. 4. Unupdated software can be patched by regularly checking and updating the MySQL version.

Identifying slow queries in MySQL can be achieved by enabling slow query logs and setting thresholds. 1. Enable slow query logs and set thresholds. 2. View and analyze slow query log files, and use tools such as mysqldumpslow or pt-query-digest for in-depth analysis. 3. Optimizing slow queries can be achieved through index optimization, query rewriting and avoiding the use of SELECT*.

To monitor the health and performance of MySQL servers, you should pay attention to system health, performance metrics and query execution. 1) Monitor system health: Use top, htop or SHOWGLOBALSTATUS commands to view CPU, memory, disk I/O and network activities. 2) Track performance indicators: monitor key indicators such as query number per second, average query time and cache hit rate. 3) Ensure query execution optimization: Enable slow query logs, record and optimize queries whose execution time exceeds the set threshold.

The main difference between MySQL and MariaDB is performance, functionality and license: 1. MySQL is developed by Oracle, and MariaDB is its fork. 2. MariaDB may perform better in high load environments. 3.MariaDB provides more storage engines and functions. 4.MySQL adopts a dual license, and MariaDB is completely open source. The existing infrastructure, performance requirements, functional requirements and license costs should be taken into account when choosing.

MySQL uses a GPL license. 1) The GPL license allows the free use, modification and distribution of MySQL, but the modified distribution must comply with GPL. 2) Commercial licenses can avoid public modifications and are suitable for commercial applications that require confidentiality.

The situations when choosing InnoDB instead of MyISAM include: 1) transaction support, 2) high concurrency environment, 3) high data consistency; conversely, the situation when choosing MyISAM includes: 1) mainly read operations, 2) no transaction support is required. InnoDB is suitable for applications that require high data consistency and transaction processing, such as e-commerce platforms, while MyISAM is suitable for read-intensive and transaction-free applications such as blog systems.

In MySQL, the function of foreign keys is to establish the relationship between tables and ensure the consistency and integrity of the data. Foreign keys maintain the effectiveness of data through reference integrity checks and cascading operations. Pay attention to performance optimization and avoid common errors when using them.
