mysql备份脚本-白红宇

在网上看了几个脚本根据网上的稍微修改了下，稍微更准确了点，就是缺少记录日志的功能，还没想好怎么写，后续添加

#!/bin/bash

#做大备份数量

Backup_Max_Files=20

#数据库备份目录

WORKING_DIR=$(dirname "$0")

export WORKING_DIR=$(cd -P "$WORKING_DIR"/ > /dev/null; pwd)

#数据库IP地址、帐号、密码

DB_Host="XXXXXXX"

DB_User="XXXXXX"

DB_Password="XXXXXXX"

#需要备份的数据库

Databases=(

"mysql"

"zabbix"

)

#==========

echo "###########Bash Shell MySql Databases Backup Tools!"

#定义变量=当前日期

Date_Time=$(date +%F)

#定义备份文件前缀

BackDataFile=zhang"${Date_Time}"

cd $WORKING_DIR

mkdir $BackData_File

#统计需要备份数据库的个数

count=0

while [ "x${Databases[count]}" != "x" ]

count=$((count + 1))

echo "Databases=$count"

done

echo "[+] ${count} The database is about to be backed up"

for Databases in ${Databases[@]}

echo "[+] MySql-backing up: ${Databases}"

echo -n " MySql Backup Start: "

echo $(date +"%Y-%m-%d %H:%M:%S")

#使用Mysqdump工具进行逻辑备份（全备）并使用邮件脚本发送成功失败提醒

if $(mysqldump -h${DB_Host} -u${DB_User} -p${DB_Password} --single-transaction --flush-logs mysql > ${BackData_File}/${Databases}.sql )

then

echo " Success OK!: Mysql database backup success!"

python /root/jiaoben/mail.py "y@163.com" "${Databases}数据库备份成功" "${Databases}>数据库备份成功"

else

echo " Error NO!: Failure of MySQL database backup!"

#python /root/jiaoben/mail.py "y@163.com" "${Databases}数据库备份失败" "${Databases}>数据库备份失败请查看"

echo -n "Backup success: "

echo $(date +"%Y-%m-%d %H:%M:%S")

done

echo

echo "[+] Packaging and compressing folders with Tar ...."

#使用tar命令打包并压缩生成的数据库文件

cd $WORKING_DIR

tar -cv ${BackData_File} | bzip2 > ${BackData_File}.tar.bz2 && rm -rf ${BackData_File}

#删除n天以前备份的数据文件

echo "[+] Delete over time database backup files ...."

find $WORKINGDIR -name "zhang*.tar.bz2" -mtime +${Backup_Max_Files} -exec rm -rf {} \;

#find $WORKINGDIR -name "zhang*.tar.bz2" -mtime +${Backup_Max_Files} -exec ls {} \;

后补：邮件报警脚本（网络版，已测试可以使用没有问题）

#!/usr/bin/python

coding=utf-8

#测试方法：python 5.py XXXXX@163.com test test

#能正常发送邮件说明成功

import smtplib

import sys

from email.mime.text import MIMEText

class send_mail():
