创建单独用于备份的用户，并授予相应的权限

create user db_backup@'localhost' identified by 'backup123';
grant select,lock tables,show view,trigger,event on backup_database.* to db_backup@'localhost';
grant reload,Replication client on *.* to db_backup@'localhost';

方案 1：全量逻辑备份(使用 mysqldump,方案 1)

备份

#!/bin/bash
backup_file_name=db_backup_`date '+%Y-%m-%d'`.sql.gz
mysqldump -udb_backup -pbackup123 --single-transaction --flush-logs --master-data=2 backup_database | gzip > $backup_file_name

if [ -e $backup_file_name ] ;then
   echo "Start to copy files"
#   scp $backup_file_name  lihu@ubuntu-vm-02:/home/lihu
else
   echo "No file to copy"
fi

额外的参数 --skip-add-drop-table：生成的备份文件中不要有 drop table 的语句，默认是有的。 --no-data：不导出数据，仅导出表结构 --no-create-info：不导出建表语句，仅导出数据
