1、先写一个python脚本
vim /opt/mysql_dump.py
#!/usr/bin/env python
# -*- coding:utf-8 -*-
import os
import time
databases = '--all-database'
Mysql_username = 'root'
Mysql_password = '123456'
Mysql_dir = '/opt/mysql'
databases_name = 'database'
def Mysql_dump_file():
mkdir_dir = '/opt/'+time.strftime('%Y%M')+'/'
if not os.path.exists(mkdir_dir):
os.mkdir(mkdir_dir)
os.chdir(mkdir_dir)
today_sql=mkdir_dir+databases_name+'_'+time.strftime('%Y%m%d')+'.sql'
sql_comm = "mysqldump -u %s -p'%s' -R --events --quick --single-transaction %s > %s"%(Mysql_username,Mysql_password,databases,today_sql)
os.system(sql_comm)
if __name__ == '__main__':
Mysql_dump_file()
2、写一个计划任务
crontab -e进入计划任务编写模式(这里是每天凌晨3点自动备份数据库)
