1. Backup
The database exports SQL scripts and backs up the contents of the database, not the database!
- mysqldump -u username -p password database name> path to the generated script file. For example: mysqldump -uroot -p123 mydb3>d:\mydb3.sql (same as mysql.exe and mysqld.exe, both in the bin directory)
- Note, don’t put a semicolon, don’t log in to mysql, run directly under cmd
- Note that the generated script file does not contain the create database statement
You can see the backed up data under the D drive!
2. Recovery
2.1 The first way
mysql -u用户名 -p密码 数据库<脚本文件路径The operation steps are as follows:
- Delete the mydb3 database first, and then recreate the mydb3 database
- mysql -uroot -p123 mydb3<d:\mydb3.sql
- Note, don’t put a semicolon, don’t log in to mysql, run directly under cmd
2.2 The second way
登录mysql
source SQL脚本路径The operation steps are as follows:
- Delete the mydb3 database first, and then recreate the mydb3 database
- Switch to mydb3 library
- source d:\mydb3.sql
