这篇文章将为大家详细讲解有关怎样利用python 发送MySQL慢日志邮件，文章内容质量较高，因此小编分享给大家做个参考，希望大家阅读完这篇文章后对相关知识有一定的了解。
一 需求
因为开发针对某系统做稳定性建设，需要对数据库系统的慢日志进行审计，检查优化。和开发沟通选择定期发送慢查询到开发的邮箱的方式,每日汇总，然后一起评估 优化slow query 。
二 工具实现
mail.py 脚本
#!/usr/bin/env python
# -*- coding: utf-8 -*-
# mail.py
import os.path
import time
import sys
import os
import json
import string
import random
import smtplib
import time
from datetime import date
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.image import MIMEImage
from email.Header import Header
from email.MIMEText import MIMEText
from email.MIMEMultipart import MIMEMultipart
mail_user="xxx@xxxx.com";
mail_pass="xxxxx";
mail_smtp_server="smtp.xxxxx.com";
mail_smtp_port= 25
def sendMail(contents,subject,attach,mail_to):
lTime=str(time.strftime('%Y%m%d_%H',time.localtime(time.time())))
msg = MIMEMultipart('related');
if subject=="":
subject='test';
msg['Subject'] = subject+" Time:"+ lTime;
msg['From'] = mail_user;
msg['To'] = ";".join(mail_to) ;
html="";
for cont in contents:
html = html+cont[0];
msgHtml = MIMEMultipart('alternative');
msgHtml.set_charset('UTF-8');
msgAtt = MIMEText(open(attach,'rb').read(),'base','gbk');
msgAtt["Content-Type"] = 'application/octet-stream'
msgAtt["Content-Disposition"] = 'attachment; filename="'+subject+'"'
msg.attach(msgAtt);
try:
smtp = smtplib.SMTP();
smtp.connect(mail_smtp_server,mail_smtp_port)
smtp.login(mail_user,mail_pass);
smtp.sendmail(mail_user,mail_to,msg.as_string());
smtp.close();
except Exception,e:
print str(e)
sendSlowlog.py
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import mail ##使用了上述脚本
import sys
import time
import os
import datetime
from datetime import date
from os.path import join, getsize
def sendSlowlog(subject_info,attach,mail_to):
size = os.path.getsize(attach)
if(size > 1):
mail.sendMail("",subject_info,attach,mail_to)
if __name__ == '__main__':
mail_to=["qilong.yangql@xxxx.com"]
lDate=str(time.strftime('%Y%m%d',time.localtime(time.time())))
lTime=str(time.strftime('%Y%m%d_%H',time.localtime(time.time())))
subject_info="Slowlog of DBname" + lTime
attach="/u01/my3306/log/slow_"+ lDate +"/slow.log."+lTime
sendSlowlog(subject_info,attach,mail_to)
注
本系统已经每小时将slow log 进行分割，关于如何切割，各位可以思考一下。
