一、前言
刚刚开始学python,还在看一套简单的python教学视频,但还未看完,简单的写了个mysql备份脚本,也算是第一个python脚本的×××座哈~~,因为才刚刚才开始,对python 的class 、function、build-in function 、模块 等等,怎么使用,什么时候使用都没什么概念 ,由于第一个,所以仅此记录一下吧,也欢迎路过的pythoner赐教。
二、脚本
环境:Centos 6.3
Python 2.6.6
脚本如下:
#!/usr/bin/env python # author: kuangl # -*- coding: utf-8 -*- # filename: mysql_back_zhubao.py import os import time import string ''' defined variable ''' databases=['kaixin'] sql_user='root' sql_pwd=['kwqsk123p;/$'] ''' Defining the remote backup variables ''' jv_test01_ip="192.168.1.16" jv_test01_user="kuangl" jv_test01_port='61239' jv_test01_dir="/home/kuangl/zhubao_mysql/" ''' Create the backup file directory ''' mkdir_dir="/home/kuangl/backup/jewelvary/"+time.strftime('%Y%m')+"/" if not os.path.exists(mkdir_dir): os.mkdir(mkdir_dir) print 'Successfully created directory', mkdir_dir ''' Start backup of database to the specified directory ''' for database_name in databases: os.chdir(mkdir_dir) today_sql=mkdir_dir+database_name+'_'+time.strftime('%Y%m%d')+'.sql' sql_comm="mysqldump -u %s -p'%s' %s > %s"%(sql_user,sql_pwd[0],database_name,today_sql) if os.system(sql_comm) == 0: print database_name,'is backup successfully!' else: print database_name,'is backup Failed!!' time.sleep(3) scp_comm="scp -P%s %s %s@%s:%s "% (jw_admin_port,today_sql,jw_admin_user,jw_admin_ip,jw_admin_dir) if os.system(scp_comm) == 0: print today_sql,'This file backup to jv_test01 success!' else: print today_sql,'This file backup to jv_test01 Failed!!'
三、测试
[kuangl@jv-test01 ~]$ ./mysql_back_zhubao.py kaixin is backup successfully! kaixin_20130806.sql 100% 1997KB 2.0MB/s 00:00 /home/kuangl/backup/jewelvary/201308/kaixin_20130806.sql This file backup to jv-test01 success!
