一、需求背景
需要迁移Mysql数据库，图形化界面备份还原速度太慢。数据量较大，通过命令行执行备份还原。
A服务器：需要迁移的数据库（公网）；
B服务器：迁移目标库（内网）
二、Mysql数据库备份（内网操作）
将远程服务器的库备份到本地：
mysqldump -h 124.x.x.x -P 33606 -u root -pxxx store > store.sql
三、Mysql数据库还原
1、创建名称为store的数据库，编码格式UTF8
CREATE DATABASE store CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;2、进入数据库：
mysql: [Warning] Using a password on the command line interface can be insecure.Welcome to the MySQL monitor. Commands end with ; or g.Your MySQL connection id is 130Server version: 5.7.34-log MySQL Community Server (GPL)Copyright (c) 2000, 2021, Oracle and/or its affiliates.Oracle is a registered trademark of Oracle Corporation and/or itsaffiliates. Other names may be trademarks of their respectiveowners.Type 'help;' or 'h' for help. Type 'c' to clear the current input statement.mysql> CREATE DATABASE store CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;Query OK, 1 row affected (0.02 sec)mysql> use store;Database changedmysql> show tables;Empty set (0.00 sec)
3、导入数据库sql文件：
source /home2/demo_envs/store/store.sql
