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。
