将指定数据库实例MYSQL_HOST、MYSQL_PORT、MYSQL_USER、MYSQL_PASSWORD中的所有数据库表结构、数据导出到指定目录BACKUP_DIR下的多个单独的SQL脚本每个SQL脚本名称即为数据库名如my_db.sql脚本的数据库名为my_db且排除内置的mysql、sys、information_schema、performance_schema数据库具体导出脚本backup.sh内容如下
#!/bin/bash# MySQL credentials
MYSQL_USERroot
MYSQL_PASSWORDmyPassw
MYSQL_HOST127.0.0.1
MYSQL_PORT3306# Directory for backups
BACKUP_DIRbackup-dir# Create backup directory if it doesnt exist

done导入数据库
将备份目录SQL_DIR下的多个sql脚本恢复到指定数据库实例MYSQL_HOST、MYSQL_PORT、MYSQL_USER、MYSQL_PASSWORD中每个sql脚本名称即为数据库名如my_db.sql脚本的数据库名为my_db批量建库、导入SQL脚本的restore.sh内容如下
