Backing Up and Restoring MySQL Dumps!
Hi Guys who are a novice to the DevOps Industry or Experts come across instances where they need to take a backup of the database, so today my article is about how to take a MySQL Backup and to restore it. These commands are all done through the terminal where MySQL resides.
- Taking a Backup
mysqldump -u {username} –p {password} {database_name} > {dump_file.sql}
When taking this command more closely, the values within curly brackets should be replaced with appropriate values.
- mysqldump → the command it will execute
- -u → this should be followed with the username for the
- -p → this should be followed by the password you can either fill it or leave it as it is with a blank, if you don't specify the password here you will be prompted to enter the password when you execute the command.
- database name → After leaving a space for the password, the database
- dump_file.sql → the name for the output of the file
ps — It's a best practice that you name the dump file as follows, the database name followed by the date and time it was taken and storing it inside a folder dedicated for database backups.
- example → DatabaseName-DDMMYYYY:HHMM
2. Restoring the Backup
Initially locate where you have stored the backup, and enter the following command the values of the curly brackets should be,
MySQL -u {username} –p{password} {database_name} < {dump_file.sql}
As in the previous command,
- MySQL → the command type to execute
- -u → the username used for MySQL
- -p → the valid password for the mentioned username
- database_name → the desired database it should be restored
- dump_file.sql → the exact file it should restore.
I hope this will be helpful to make your work efficient and easy! Stay Safe and Keep Going! Never Give Up!
