Bash Script: Create MySQL Database & User with Optional Password

January 3, 2017  |  No Comments  |  by Raj (MagePsycho)  |  Linux, Mysql

I have been using DigitalOcean for my personal projects. And one repeated things that I had to do is the creation of MySQL database & user. I know I could have used some CPanel like GUIs and even some of them came to my mind like VestaCP, Ajenti, ServerPilot etc. But all comes with sort of things and not so developer friendly.

So I decided to create a simple bash script that can simply the database & user.

Bash Script Code

You can find the script at Gist:

How to use?

1# Download
Download the script from Gist – Bash Script: Create MySQL Database & User

2# Set Permission
You need to set the executable permission in order to execute the shell script:

chmod +x mysql-create-db-user.sh

3# Usage
Use the script as:

./mysql-create-db-user.sh [--host="<host-name>"] --database="<db-name>" [--user="<db-user>"] [--pass="<user-password>"]

So the only required parameter is database name. In the case of empty values for other parameters:

  • ‘host’ becomes localhost
  • ‘user’ takes value from database name
  • ‘password’ is randomly generated

For the following command:

./mysql-create-db-user.sh --database=bash_db2

The output looks like:

Bash Script: Create MySQL Database & User with Optional Password

Bash Script Console: Create MySQL Database & User with Optional Password

Hope you find this script useful.
