How to Download and Create Sample Database in MySql


In this article, we are going to demonstrate How to Download & Create Sample Database in MySql. You can download a sample database for MySql directly inside mysql server or download it first from GitHub and then transfer it to mysql server.


Click here to download the sample database from GitHub, Click on the green button CODE and then Click on Download Zip, refer to below image.


Alternatively, you can also download a sample database directly inside Server using wget command (require internet access). I will create a new directory as a backup and will download it inside the backup dirrectory. Once master.zip file downloaded unzip it. Follow the below steps:

[root@test-machine01 u01]# mkdir backup
[root@test-machine01 u01]# chown -R mysql:mysql backup
[root@test-machine01 u01]# ls -ld backup
drwxr-xr-x. 2 mysql mysql 6 Jan 18 10:43 backup

[root@test-machine01 u01]# cd backup
[root@test-machine01 backup]# wget 'https://codeload.github.com/datacharmer/test_db/zip/master' -O master.zip
