在Ubuntu 7.10下安装好mysql后,root帐户的密码为空,用如下方式登录:
mysql -u root
这里就要设置mysql的安全性了。
设置mysql root用户的密码。
用mysqladmin来设置密码
mysqlmyadmin -u root password 123456
如果有旧密码:
mysqladmin -u root -p password newpass
这时shell会提醒你输入旧密码。更改成功。
另一种方法是进入mysql后更改密码。
set password for 'root'@'localhost'=password('newpass');
或用update 进行更改。
update mysql.user set password=password('newpass') where user='root';
flush privileges;
增加用户
有两种方式
1. grant语句。
grant all privileges on *.* to 'someuser'@'localhost' identified by 'pass' with grant option;
2. 使用update语句,可是有点复杂,,主要是要搞清楚user表的相关内容。

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.

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),
