phpmyadmin用root无法登录(用户名和密码都正确)
解决:
看mysql客户端是否可以登录(我遇到的是不能登录),若无法登录就更改root密码,改好后就可以登录了。phpmyadmin刷新页面后登录。
phpmyadmin进入页面后无法浏览数据库里面的内容,左边会出现错误 #1146 - Table 'phpmyadmin.pma_recent' doesn't exist
解决:
find / -name create_tables.sql '查找这张表的位置,该表为开启phpmyadmin高级功能所需要的表在phpmyadmin中导入这张表,就不会报此错误了。
在phpmyadmin登录页面的下方显示 ‘使用配置文件中定义的控制用户连接失败’,进入页面也会显示
解决:
find / -name config.inc.php '找到该文件的位置 cp /etc/phpmyadmin/config.inc.php ./config.inc.php.bak '我的文件在该位置,先把它一下, vim config.in.php '编辑该文件 找到 $cfg['Servers'][$i]['controluser']和$cfg['Servers'][$i]['controluser'] 这两个设置 前面的一个的值改成mysql用户名,后面一个改成对应密码,像下面的一样: $cfg['Servers'][$i]['controluser'] = 'root'; $cfg['Servers'][$i]['controlpass'] = '123456789';刷新phpmyadmin就不会显示了。

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.
