mysql command to backup database
|
1. mysql database backup command MySQL database backup using command line For example: Database address: 127.0.0.1 Database username: root Database password: pass Database name: myweb Back up the database to D drive and directory mysqldump -h127.0.0.1 -uroot -ppass myweb > d:/backupfile.sql Back up to the current directory. Back up the MySQL database in a format with a delete table, which allows the backup to overwrite the existing database without manually deleting the original database mysqldump --add-drop-table -h127.0.0.1 -uroot -ppass myweb > backupfile.sql Directly compress and back up the MySQL database to the D drive and directory mysqldump -h127.0.0.1 -uroot -ppass myweb | gzip > d:/backupfile.sql.gz Back up a certain table(s) of the MySQL database. This example backs up the table1 table and table2 table. Back up to /home of the Linux host mysqldump -h127.0.0.1 -uroot -ppass myweb table1 table2 > /home/backupfile.sql Back up multiple MySQL databases at the same time mysqldump -h127.0.0.1 -uroot -ppass --databases myweb myweb2 > multibackupfile.sql Only the database structure is backed up. Back up the database named myweb and the database named myweb2 at the same time mysqldump --no-data -h127.0.0.1 -uroot -ppass --databases myweb myweb2 > structurebackupfile.sql Back up all databases on the server mysqldump --all-databases -h127.0.0.1 -uroot -ppass > allbackupfile.sql Command to restore MySQL database. Restore the current backup database named backupfile.sql mysql -h127.0.0.1 -uroot -ppass myweb < backupfile.sql Restore compressed MySQL database gunzip < backupfile.sql.gz | mysql -h127.0.0.1 -uroot -ppass myweb Move the database to the new server. This example is to copy the local database myweb to the remote database named serweb, where the remote database must have a database named serweb mysqldump -h127.0.0.1 -uroot -ppass myweb | mysql --host=***.***.***.*** -u database username -p database password -C serweb 2. Use multiple backup software (1) Open the MySQL database backup and fill in the database related parameters. IP: Default 127.0.0.1; Domain name: localhost Username: the account name used to log in to the database Password: Password to log in to the database Port number: Default 3306, or find mysql.ext and open it, enter the password and press Enter, enter "show global variables like 'port';" after mysql> and press Enter 
(2) After filling in the parameters, click "Next", check the database that needs to be backed up, and click "Finish". The task will be created (the files will start to be automatically backed up)
(3) Click "Set Frequency" under "Operation" to set the task backup frequency; "Edit Parameters" to set the user name, password, and port number for connecting to the database; "Backup Content" reselects the database that needs to be backed up.
Tip: If you need to create another database backup task, click "Backup Content" under "Operation", click "Add Database", and then follow the same steps as when creating the first database task. (If you are prompted that the number of tasks is not enough, please go to the official website to redeem the number of tasks; only one of the same database can be created)
3.3. SQL Server database backup (1) Open the MSSQL database and fill in the relevant parameters; Instance name: Under normal circumstances, all instance names will be displayed for you to choose. Click "Edit" to fill in manually Username: the account name used to log in to the database Password: Password to log in to the database
(2) Other steps are the same as backing up the MySQL database, as above. Summary: Comparing the above two methods, it is obviously easier to use multiple backup software. Not having to manually back up saves a lot of time and energy; and using multiple backups allows you to monitor the backup status in real time and solve problems immediately if you encounter them. The final result of the backup will also be notified to the user by email, so you don’t have to worry about whether the backup was successful when restoring. If you are interested, just use it quickly! |

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
How does session hijacking work and how can you mitigate it in PHP?
Apr 06, 2025 am 12:02 AM
Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.
Describe the SOLID principles and how they apply to PHP development.
Apr 03, 2025 am 12:04 AM
The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Apr 03, 2025 am 12:04 AM
Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
