这篇文章给大家介绍 python MySQLdb 如何配置 python 链接 MYSQL，内容非常详细，感兴趣的小伙伴们可以参考借鉴，希望对大家能有所帮助。

1、下载 MySQL for Python
wget http://sourceforge.net/projects/mysql-python/files/mysql-python/1.2.3/MySQL-python-1.2.3.tar.gz

2、安装
yum install python-devel-2.7.5-48.el7.x86_64
tar zxvf MySQL-python-1.2.3.tar.gz
$ cd MySQL-python-1.2.3

修改 setup_posix.py 中 mysql_config.path =“mysql_config”修改为你 mysql 软件下对应路径  
mysql_config.path = /home/mysql/soft/mysql5717/bin/mysql_config
 
$ python setup.py build
$ python setup.py install

[root@node1 lib]# python testconn.py 
Traceback (most recent call last):
  File testconn.py , line 3, in module
    import MySQLdb    
  File build/bdist.linux-x86_64/egg/MySQLdb/__init__.py , line 19, in module
  File build/bdist.linux-x86_64/egg/_mysql.py , line 7, in module
  File build/bdist.linux-x86_64/egg/_mysql.py , line 6, in __bootstrap__
ImportError: libmysqlclient.so.20: cannot open shared object file: No such file or directory
[root@node1 lib]# find / -name libmysqlclient
[root@node1 lib]# find / -name libmysqlclient.so.20
/home/mysql/soft/mysql5717/lib/libmysqlclient.so.20

做一个软连接到 /usr/lib64 目录（64 为系统）
 ln -s /home/mysql/soft/mysql5717/lib/libmysqlclient.so.20  /usr/lib64/libmysqlclient.so.20

还是有报错找不到 socket

[root@node1 duanfj]# python testconn.py 
Traceback (most recent call last):
  File testconn.py , line 6, in module
    conn=MySQLdb.connect(host= localhost ,user= root ,passwd= root ,db= test ,port=3306,charset= utf8)  
  File build/bdist.linux-x86_64/egg/MySQLdb/__init__.py , line 81, in Connect
  File build/bdist.linux-x86_64/egg/MySQLdb/connections.py , line 187, in __init__
_mysql_exceptions.OperationalError: (2002, Can t connect to local MySQL server through socket /tmp/mysql.sock (2) )

这个简单   做个软链接   大功告成
ln -s /tmp/my3306.sock /tmp/mysql.sock

[root@node1 MySQL-python-1.2.3]# python testconn.py 
1
1
row1
2
row2
3
row
4
row4
[root@node1 MySQL-python-1.2.3]# 
##############
[root@node1 MySQL-python-1.2.3]# cat testconn.py 
# -*- coding: utf-8 -*-    
#mysqldb    
import MySQLdb    
   
# 连接    
conn=MySQLdb.connect(host= localhost ,user= root ,passwd= root ,db= test ,port=3306,charset= utf8)  
cursor = conn.cursor()    
   
# 写入    
sql = insert into test(a,b) values(%s,%s)  
param = (4, row4)    
n = cursor.execute(sql,param)    
print n    

# 查询    
n = cursor.execute(select * from test)    
for row in cursor.fetchall():    
    for r in row:    
        print r    
   
# 删除    

# 关闭    
conn.close()
