CentOS下安装python-mysqldb

1、#    yum install python-devel mysql-devel zlib-devel openssl-devel

2、http://pypi.python.org/pypi/MySQL-python/#downloads 下载安装包

      #    wget   http://pypi.python.org/packages/source/M/MySQL-python/MySQL-python-1.2.3.tar.gz

3、http://pypi.python.org/pypi/setuptools#downloads  下载工具

     #    wget   http://pypi.python.org/packages/2.4/s/setuptools/setuptools-0.6c11-py2.4.egg

4、先安装工具

    #  sh setuptools-0.6c11-py2.4.egg

    #  python

    >>>   import  setuptools

   不提示错误表示成功

5、安装  MySQL-python-1.2.3.tar.gz

    #    tar -zxvf MySQL-python-1.2.3.tar.gz

    #    cd   MySQL-python-1.2.3

    #    vi setup_posix.py

   找到mysql_config.path 一行，改为mysql_config.path = "/usr/bin/mysql_config"

   #   python setup.py build

   #   python setup.py install

   #    python

    >>>   import  MySQLdb

不提示错误表示成功

Python 操作数据库 连接创建库：

#! /usr/bin/env python
import MySQLdb
conn = MySQLdb.connect(host='localhost',user='root',passwd='root',charset='utf8')
cursor = conn.cursor()

#Crete Database
#cursor.execute("""create database python """) 

#Select Database
conn.select_db('python');

#Create Table
#cursor.execute("""create table gaiqi(id int(4),info varchar(100)) """)

#Insert data
#value = [1,"inserted"];
#cursor.execute("insert into test values(%s,%s)",value);

#Insert more
values=[]
for i in range(20):
   values.append((i,'Hello Mysqldb'+str(i)))
cursor.executemany("""insert into test values(%s,%s)""",values);

cursor.close();

查询记录

#! /usr/bin/env python
import MySQLdb
conn = MySQLdb.connect(host='localhost',user='root',passwd='root',db='python',charset='utf8')
cursor = conn.cursor()
count = cursor.execute('select * from test')
print 'All Total %s',count

#Get 1 Result
result = cursor.fetchone();
print result
print 'ID:%s  inof:%s'% result

#Get 5 Result
results = cursor.fetchmany(5)
for r in results:
  print r

#Get All Result
res = cursor.fetchall()
for r in res:
  print r
  
  
cursor.close();

插入时间：

import time
print time.strftime('%Y-%m-%d %H:%M:%S',time.localtime(time.time()))

备份文件：

#! /usr/bin/env python

import os
import time

source = ['/var/www/html','/var/test']
target_dir = '/mnt/backup/'
target = target_dir+time.strftime('%Y%m%d%H%M%S')+'.zip'
today = target_dir+ time.strftime('%Y%m%d')
now = time.strftime('%H%M%S')
if not os.path.exists(today):
  os.mkdir(today)
  print 'Dir OK',today

target = today+os.sep+now+'.zip'
zip_command = "zip -qr '%s' %s" % (target,' '.join(source))
if os.system(zip_command) == 0:
  print 'Success Backup to',target
else:
  print 'Failed Backup'
