Step 1: First log in to MySQL
Enter the following command in the terminal to enter the MySQL console:
sudo mysql
If you enter this You will be prompted for a password after the command. Please enter the password of your root user.
Step 2: Change the password
After we enter the MySQL console, we can start to change the password of the root user. Follow the command below to set the password:
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'new_password';
'new_password' is the new password you want to set.
Step 3: Refresh permissions
After running the above command, you need to refresh the permissions so that MySQL can use the new password to authenticate the root account. Enter the following command in the MySQL console:
FLUSH PRIVILEGES;
Step 4: Exit MySQL
After completing the password change, you can exit MySQL through the following command:
exit
Now you have successfully changed the password of the root account.
How to set a secure MySQL root password
For a network-based service, password security is very important. If a hacker cracks the root account, they can easily access the database, which will have serious consequences for the user and the company. Therefore, when setting the MySQL root password, you must abide by the following rules:
The password must be no less than 10 characters long
The password consists of letters , numbers and symbols
Avoid using easy-to-guess passwords, such as birthday, 123456, etc.
Avoid using public information, such as company name or Your name
Change your password regularly
If you are not sure how to set a strong password, you can use some password generator tools, such as 1Password or LastPass.

The steps for upgrading MySQL database include: 1. Backup the database, 2. Stop the current MySQL service, 3. Install the new version of MySQL, 4. Start the new version of MySQL service, 5. Recover the database. Compatibility issues are required during the upgrade process, and advanced tools such as PerconaToolkit can be used for testing and optimization.

MySQL backup policies include logical backup, physical backup, incremental backup, replication-based backup, and cloud backup. 1. Logical backup uses mysqldump to export database structure and data, which is suitable for small databases and version migrations. 2. Physical backups are fast and comprehensive by copying data files, but require database consistency. 3. Incremental backup uses binary logging to record changes, which is suitable for large databases. 4. Replication-based backup reduces the impact on the production system by backing up from the server. 5. Cloud backups such as AmazonRDS provide automation solutions, but costs and control need to be considered. When selecting a policy, database size, downtime tolerance, recovery time, and recovery point goals should be considered.

Optimizing database schema design in MySQL can improve performance through the following steps: 1. Index optimization: Create indexes on common query columns, balancing the overhead of query and inserting updates. 2. Table structure optimization: Reduce data redundancy through normalization or anti-normalization and improve access efficiency. 3. Data type selection: Use appropriate data types, such as INT instead of VARCHAR, to reduce storage space. 4. Partitioning and sub-table: For large data volumes, use partitioning and sub-table to disperse data to improve query and maintenance efficiency.

MySQL functions can be used for data processing and calculation. 1. Basic usage includes string processing, date calculation and mathematical operations. 2. Advanced usage involves combining multiple functions to implement complex operations. 3. Performance optimization requires avoiding the use of functions in the WHERE clause and using GROUPBY and temporary tables.

Efficient methods for batch inserting data in MySQL include: 1. Using INSERTINTO...VALUES syntax, 2. Using LOADDATAINFILE command, 3. Using transaction processing, 4. Adjust batch size, 5. Disable indexing, 6. Using INSERTIGNORE or INSERT...ONDUPLICATEKEYUPDATE, these methods can significantly improve database operation efficiency.

In MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.

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),
