Python 3 pymysql 데이터베이스 액세스 - 다음 오류가 발생하는 데이터베이스에 연결

Question

파이썬 3.5를 통해 DB를 연결하는 동안이 문제에 대해 도움을받을 수있는 사람이 누구입니까? 오류 수신 후.

import pymysql 

# Open database connection 
db = pymysql.connect("localhost","testuser","test123","TESTDB",) 

# prepare a cursor object using cursor() method 
cursor = db.cursor() 

# execute SQL query using execute() method. 
cursor.execute("SELECT VERSION()") 

# Fetch a single row using fetchone() method. 
data = cursor.fetchone() 

print ("Database version : %s " % data) 

# disconnect from server 
db.close() 

오류 :

Answer 1

당신이 MySQL이 가지고있는 help

The error (2003) Can't connect to MySQL server on 'server' (10061) indicates that the network connection has been refused. You should check that there is a MySQL server running, that it has network connections enabled, and that the network port you specified is the one configured on the server.
