How to remotely debug Pycharm and MySQL database authorization issues
1. Pycharm configuration
1. 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

Big data structure processing skills: Chunking: Break down the data set and process it in chunks to reduce memory consumption. Generator: Generate data items one by one without loading the entire data set, suitable for unlimited data sets. Streaming: Read files or query results line by line, suitable for large files or remote data. External storage: For very large data sets, store the data in a database or NoSQL.

MySQL query performance can be optimized by building indexes that reduce lookup time from linear complexity to logarithmic complexity. Use PreparedStatements to prevent SQL injection and improve query performance. Limit query results and reduce the amount of data processed by the server. Optimize join queries, including using appropriate join types, creating indexes, and considering using subqueries. Analyze queries to identify bottlenecks; use caching to reduce database load; optimize PHP code to minimize overhead.
