Python2使用mysqldb讲义

本文主要给大家介绍，希望可以给大家补充和更新些知识，如有其它问题需要了解的可以持续在行业资讯里面关注我的更新文章的。

PyMySQL 是在 Python3.x 版本中用于连接 MySQL 云服务器的一个库，Python2中则使用mysqldb
话不多说，直接上代码来说明用途

#!/user/bin/env python
#coding=utf-8

from pymysql import connect,cursors
from pymysql.err import OperationalError
import os
import configparser as cparser
from builtins import int
from framework.logger import Logger
import time

'''
========读取config.ini文件中mysql配置========
'''
base_dir = str(os.path.dirname(os.path.dirname(file)))
file_path = base_dir + "\config\config.ini"

cf = configUtil(file_path)
host = cf.get("sitmysqlconf", "host")
port = cf.get("sitmysqlconf", 'port')
db = cf.get("sitmysqlconf", 'db_name')
user = cf.get("sitmysqlconf", 'user')
password = cf.get("sitmysqlconf", 'password')

logger = Logger(logger="mysqlUtils").getlog()
