If you are looking to create a backup of your MySQL database, then the mysqldump command is an excellent tool to use. In this tutorial, you will learn how to use the mysqldump command to create backups of your MySQL databases.
Step 1 – Connect to MySQL
To use the mysqldump command, you first need to connect to your MySQL server using the following command:
mysql -u USERNAME -p
Replace ‘USERNAME’ with your MySQL username. You will be prompted to enter your password before connecting to the MySQL server.
Step 2 – Choose Database
Once you have successfully connected to the MySQL server, you can choose the database you want to backup using the following command:
Replace ‘DATABASE_NAME’ with the name of the database you wish to backup.
Step 3 – Use mysqldump Command
Now that you have chosen the database you want to backup, you can use the mysqldump command to create a backup. The basic syntax for the mysqldump command is as follows:
mysqldump -u USERNAME -p DATABASE_NAME > backup.sql
This command will create a backup of the chosen database and save it to the file ‘backup.sql’. Replace ‘USERNAME’ with your MySQL username and ‘DATABASE_NAME’ with the name of the database you wish to backup.
If you run the mysqldump command, you should see output similar to the following:
-- MySQL dump 10.13 Distrib 5.7.20, for macos10.13 (x86_64) -- -- Host: localhost Database: DATABASE_NAME -- ------------------------------------------------------ -- Server version 5.7.20 ... ... ... -- Dump completed on 2022-08-05 15:30:45
This output confirms that the backup process completed successfully.
