'''
功能:mysql备份。用mysqldump对mysql中各库进行备份
1.user,pass,host,path,del参数为变量
2.默认备份删除周期为5天，备份以天为单位
3.默认备份路径为/mysql_backup，如果不存在会建立此目录
4.用法为加执行权限，定时任务运行
'''
import os,subprocess,datetime

'''设置变量'''
MYSQL_USER = 'root'
MYSQL_PASS = 'pass'
MYSQL_HOST = 'localhost'
DEL_DAYS   = 5
BACK_PATH  = '/mysql_backup'

'''''时间设置'''
CUR_TIME = datetime.date.today()
AGO_TIME = datetime.timedelta(days=DEL_DAYS)
DEL_TIME = CUR_TIME - AGO_TIME
DATABASE = ''
