python 连接mysql数据库

1、安装依赖包
yum install gcc python-devel mysql-devel zlib-devel openssl-devel
如果是pyhon3
yum install gcc python3 python3-devel mysql-devel zlib-devel openssl-devel ncurses-devel -y
cd /usr/lib64/python3.6/
cp configparser.py ConfigParser.py
2、下载安装
https://pypi.org/project/MySQL-python/#files
gunzip MySQL-python-1.2.5.tar.gz
$ tar -xvf MySQL-python-1.2.5.tar
$ cd MySQL-python-1.2.5
$ python setup.py build
$ python setup.py install

或 pip install mysql-python

python3 使用

pip3 install pymysql
3、连接数据库
#!/usr/bin/python
# -*- coding: UTF-8 -*-

import MySQLdb

#import pymysql

# 打开数据库连接
db = MySQLdb.connect("localhost", "root", "123456", "python", charset='utf8' )

#db = pymysql.connect("localhost", "root", "123456", "python", charset='utf8')

# 使用cursor()方法获取操作游标
cursor = db.cursor()

# 使用execute方法执行SQL语句
cursor.execute("select * from userinfo")

# 使用 fetchone() 方法获取一条数据
data = cursor.fetchall()

print data

# 关闭数据库连接
cursor.close()
db.close()
