MySQL数据库备份与恢复

1、备份

1.1、导出数据库

指令 mysqldump --host 主机 --user 用户名 --password --databases 数据库名 > 导出的文件名

[root@oracle ~]# mysqldump --host 127.0.0.1 --user root --password --databases movies > /Users/oracle/Desktop/movies.sql

此时,在桌面就是看到movies.sql文件。

2、恢复

2.1、进入MySQL

指令 mysql -u 用户名 -p

[root@oracle ~]# mysql -u root -p
Enter password:
