mysql 表结构变动监控_自动监控MySQL表结构变更脚本-阿里云开发者社区

如何监控MySQL数据库表结构和表变更，并通知到相关的联系人、实现报警或通知？

由于平台采用django系统实现，因此通过如下代码实现(代码low，也可以写成python文件，传参数执行)：

简单思路：

对用户指定库的所有列值进行md5，并存储到本地数据库，每次定时执行，校对md5，并找出不匹配的进行判断

会自动找出新增、删除、变更表结构的表

# models.py

class MonitorSchema(models.Model):

table_schema = models.CharField(null=False, max_length=512)

table_name = models.CharField(null=False, max_length=512)

table_stru = models.TextField(null=False, default='')

md5_sum = models.CharField(null=False, max_length=256)

class Meta:

verbose_name = u'监控表结构变更表'

verbose_name_plural = verbose_name

permissions = ()

db_table = "dbaudit_monitor_schema"
