在代码中添加重连机制，以确保在连接失败时能够重新连接。以下是一个示例代码片段，可以使用这种方法来处理连接失败的情况：

import mysql.connector from mysql.connector import errorcode import time

config = { 'user': 'username', 'password': 'password', 'host': 'database.server.com', 'database': 'database_name', 'raise_on_warnings': True }

Define a function to handle connection failures

def handle_connection_failures(retries=5, wait=5): attempts = 0 conn = None

while attempts < retries:
    try:
        conn = mysql.connector.connect(**config)
        return conn
    except mysql.connector.Error as err:
        print(f"Error connecting to MYSQL: {err}")
        attempts += 1
        time.sleep(wait)

# If all retries are exhausted, raise an error
raise Exception("Failed to connect to MYSQL database after multiple attempts")

Use the handle_connection_failures function to establish a connection

conn = handle_connection_failures()

Perform database queries using the connection object

cursor = conn.cursor() cursor.execute("SELECT * FROM mytable") results = cursor.fetchall() print(results)

Close the connection when finished

cursor.close() conn.close()
