使用xtrabackup进行MySQL物理备份脚本

只想修改密码、用户、邮箱

#!/bin/bash
< /dev/null
    if [ ! -d $backup_dir/full ];then
        mkdir -p $backup_dir/full
    fi
    $cmd $backup_dir/full &> /dev/null && \
    (
        echo "[$(date +"%F %T")] full备份 成功" >> $mysql_backup
        echo "[full] $backup_dir/full/`ls $backup_dir/full/ | tail -1` "   >> $mysql_status
    ) || \
    (   
        send_email "full 备份失败"
        echo "[$(date +"%F %T")] full备份 失败" >> $mysql_backup
    )
}
other(){
