实现自动备份MySQL数据库

#!/bin/bash

base="/zsjdata/mysql/data"
date=$(date +%Y%m%d)
hour=$(date +%H)
time=$(date +%H%M%S)

charset="UTF8"
username="root"
password="sinykk123"
database="online_diarydbnew"
filename="$database.$date$time.sql"

cd $base

if [ ! -d $date ]
then
  mkdir ./$date
fi

dir="./$date/$date$hour"
if [ ! -d $dir ]
then
  mkdir $dir
fi

path="$base/$dir"

/usr/local/mysql/bin/mysqldump -u$username -p$password --opt --default-character-set=$charset -q $database > $path/$filename

cd $path
tar zcf ./$filename.tar.gz ./$filename
rm -r ./$filename

经过亲自测试应用，目前没有发现问题，

/usr/local/mysql/bin/mysqldump 这里请填写您的服务器 mysql 安装的实际路径
