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'
