How to remotely debug Pycharm and MySQL database authorization issues
1. Pycharm configuration
1. Deployment configuration
Tool==》Deployment==》Configuration
2. python interpreter
File==》Settings==》Project:xx==》python interpreter
3 , Run/Debug Configuration
Run==》Edit Configuration==》New python configuration
Note: is special here It should be noted that if you want to debug Django in pycharm, you need to set the formal parameters to: runserver 0:8000
This sentence can be rewritten as: In order to debug remote code locally, the Django project needs Start at 0.0.0.0:8000.
2. Mysql database authorization issues
1. settings.py
DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'computers', 'USER': 'root', 'PASSWORD': '123', 'HOST': '192.168.28.128', 'PORT': '3306' } }
Note: Here HOST can be used when running directly on the remote end. localhost", but you need to change it to the ip of the remote server when debugging the remote end with pycharm. Otherwise, the following error will occur:
django.db.utils.OperationalError: ( 1698, "Access denied for user 'root'@'localhost'")
2. mysql remote database authorization
(1) Modify the my.cnf file (ubuntu The following address is:/etc/mysql/mysql.conf.d/mysqld.cnf)
Modify if necessary and add if not:
bind-address=0.0.0.0
(2) Restart the mysqld service:
systemctl restart mysqld
(3) Link mysql
mysql -u root -p
(4) Use database mysql
use mysql;
(5) Configuration permissions
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;1
Parameter explanation:
"." -- --All resources and all permissions
"‘root’@%" — root represents the user name % represents all access addresses (you can also use a unique address to replace it, only an address can be accessed).
IDENTIFIED BY ‘root’, this root refers to the access password.
WITH GRANT OPTION allows cascading authorization
(6) It is important to refresh the system permission related table data
flush privileges;
(7) Check whether the addition is successful
select Host, User from user;
##(8) Verify remote access
Remote host address:
mysql -u root -p -h

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.

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),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.

DVWA
Damn Vulnerable Web App (DVWA) is a PHP/MySQL web application that is very vulnerable. Its main goals are to be an aid for security professionals to test their skills and tools in a legal environment, to help web developers better understand the process of securing web applications, and to help teachers/students teach/learn in a classroom environment Web application security. The goal of DVWA is to practice some of the most common web vulnerabilities through a simple and straightforward interface, with varying degrees of difficulty. Please note that this software
