在MySQL日常开发或者是维护中,有一些问题或是故障往往是难以避免的,如丢失密码、表损坏。在此总结一下常忘记MySQL的root密码解决办法:
1.登录数据库所在服务器,手动kill掉Mysql进程
关闭进程的命令为:kill 进程号
(linux下)
关闭进程的命令为:taskkill 进程号
(win下)
怎么查看进程号呢?
我们都知道MySQL的进程号一般都会保存在Mysql数据目录下的,它记录了Mysql的服务进程号。文件名为hostname.pid,如下,其中YEGZT8JOIIU2LKY为主机名。
linux下查看进程通过使用ps命令;在win下,我们也可以通过tasklist查看进程号,
打开该文件,可以看到,里面仅仅记录着进程号
现在为了方便,我主要演示win下操作,不准备打开虚拟机在测试了。如果我们不熟悉taskkill命令,可以通过taskkill /?来查看命令。
2.使用–skip-grant-tables选项重启MySQL服务
linux下
语法:./bin/mysqld_safe –skip-grant-tables
其中–skip-grant-tables选项代表启动mysql
(注意win下安装的Mysql,我使用mysqld –skip-grant-tables )
3.使用空密码的root用户连接MySQL,并修改root口令
修改如下
因为使用–skip-grant-tables启动,故使用set password命令失败。
使用update语句,直接更新mysql数据库中user表。
4.更新权限
5.重新登录
退出后,发现在此使用mysql -uroot登录,会登陆不成功,只能使用密码登陆。

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.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
