|
||
Automated Bash installer script for deploying MariaDB on Ubuntu 24.04 Server using **socket authentication** for the root account and creating a dedicated **local-only admin user** supplied at runtime.
|
||
|
||
This is a **production-focused installer**, not a demo.
|
||
|
||

|
||
|
||
### Preparing
|
||
Update your package index before running the installer:
|
||
|
||
```
|
||
sudo apt update -y
|
||
```
|
||
|
||
### Download the Script
|
||
Clone the repository from your Git server:
|
||
```
|
||
git clone https://git.x-files.dk/database/mariadb-ubuntu.git
|
||
```
|
||
|
||
```
|
||
cd mariadb-ubuntu
|
||
```
|
||
|
||
### Usage
|
||
Run the script with your chosen admin username and password:
|
||
```
|
||
sudo ./mariadbinstall -u <adminuser> -p <password>
|
||
```
|
||
|
||
### Example
|
||
```
|
||
sudo ./mariadbinstall -u mydbuser -p "StrongPassword123"
|
||
```
|
||
|
||
> **IMPORTANT**
|
||
> Always enclose the password in quotes if it contains special characters such as `$`, `!`, or `&`.
|
||

|
||
|
||
### Notes
|
||
- No `mysql_secure_installation` needed — this scipt is performing the equivalent hardening.
|
||
- The created admin user is **restricted to localhost only** for security.
|
||
- Root remains socket-authenticated by default.
|
||
|
||
> **On a side note**
|
||
> I know that on modern Ubuntu systems `mysql_secure_installation` isn’t strictly necessary anymore — but a bit of paranoia helps me sleep at night. That’s why the script still runs through the whole `mysql_secure_installation` ritual. It’s not that it’s required — I just don’t want anyone blaming me because it *wasn’t* done.
|
||
|
||
### Optional
|
||
Switching to Password Authentication. If you prefer **traditional password authentication** for the `root` user instead of socket authentication, you can switch manually:
|
||
|
||
```
|
||
sudo mariadb
|
||
```
|
||
|
||
Then run the following commands:
|
||
|
||
```
|
||
ALTER USER 'root'@'localhost' IDENTIFIED BY 'YourStrongPasswordHere';
|
||
FLUSH PRIVILEGES;
|
||
```
|
||
|
||
From now on, `root` will require a password when connecting, and socket authentication will no longer be used.
|
||
|
||
> **Note:** This change is *optional*.
|
||
> Socket authentication is faster, safer, and the modern Ubuntu default.
|
||
> But if you prefer the old-school behavior, this is all it takes.
