定时自动备份mysql

首先，利用定时shell脚本来实现

#!/bin/sh
DATE=`date +%Y-%m-%d_%H:%M:%S`
Pass='VHlrakBNeVNRTDNlZGMkUkZW'
#加密解密密码，避免报错insecure
function decrypt_passwd
{
tmp_pass=$1
dec_pass=`echo $tmp_pass|base64 -d`
}

decrypt_passwd $Pass

echo $DATE
echo '备份数据库'
/usr/bin/mysqldump -uroot -p$dec_pass --opt kidcloud > /usr/local/kidcloud/mysqlBackup/kidcloud_$DATE.sql

#!/bin/sh
DATE=`date +%Y-%m-%d_%H:%M:%S`
mysql_config_editor set --login-path=local --host=localhost --user=db_user --password
echo $DATE
echo '备份数据库'
/usr/bin/mysqldump --login-path=local --opt kidcloud > /usr/local/kidcloud/mysqlBackup/kidcloud_$DATE.sql
