Gitea Multi-Instance for Ubuntu 24.04 Server

OS Shell WebServer DB Server License

Automated Bash installer script for deploying multiple isolated Gitea instances on Ubuntu 24.04 Server.

This is a production-focused installer, not a demo.

It assumes Nginx and MariaDB are already installed and running.


If you dont have the required components, you can use these compatible installers:


Important

Always complete one installation fully (including the /etc/gitea*/gitea-postinstall step) before running another.


Download the Script

Clone this repository to your server:

git clone https://git.x-files.dk/web-application/gitea-ubuntu-multi.git
cd gitea-ubuntu-multi

Usage

Run the script using:

sudo ./giteainstall -n <domain name> -p <gitea database password> [options]

Examples

The installer automatically detects if socket authentication is active.
Only include -a and -m if your MariaDB setup does not use socket authentication.

sudo ./giteainstall -n git.example.com -p giteadbpass
sudo ./giteainstall -n git.example.com -p giteadbpass -m rootpwd
sudo ./giteainstall -n git.example.com -p giteadbpass -a admin -m adminpwd

Options

Flag Description
-p <password> Gitea database user password
-a <username> Optional MariaDB admin username (defaults to root if not specified)
-m <password> MariaDB root or admin password — required only if socket authentication is disabled
-h, --help Show the help screen (reflects detected socket status)

Logic

When you run this script:

  • Each Gitea instance created by this script is fully self-contained.
  • Every instance has:
    • Its own Linux system user (e.g., gitea1, gitea2, gitea3, …)
    • Its own database (e.g., gitea1db, gitea2db, gitea3db, …)
    • Its own service (e.g., gitea1.service, gitea2.service, …)
    • Its own home directory (e.g., /home/gitea1/, /home/gitea2/, …)
    • Its own configuration directory (e.g., /etc/gitea1/, /etc/gitea2/, …)
    • Its own data path (e.g., /var/lib/gitea1/, /var/lib/gitea2/, …)
    • A unique HTTP port automatically assigned during post-install

All instances share the same Gitea binary (/usr/local/bin/gitea),
so upgrading Gitea is simply replacing that binary once.

Instance System User Database Config Dir Service Port
1st gitea1 gitea1db /etc/gitea1/ gitea1.service 3001
2nd gitea2 gitea2db /etc/gitea2/ gitea2.service 3002
3rd gitea3 gitea3db /etc/gitea3/ gitea3.service 3003

Each instance is assigned the next available ID automatically.


Customization

Each instance has its own configuration and customization paths:

Type Path
Configuration /etc/giteaX/app.ini
Custom assets (favicon, logo, etc.) /etc/giteaX/custom/public/assets/img/
Custom templates /etc/giteaX/custom/templates/
Data & repositories /var/lib/giteaX/

Configuration

Once the script finishes, open your browser and visit:

http://<domain>

and complete the Gitea setup through the web installer form.


Post-install

After the web installer is done run:

sudo /etc/gitea*/gitea-postinstall

This adjusts ports, log levels, upload limits, disables SSH access and other tweaks.

Note

The web installer always uses temporary port 3000.
The postinstall script automatically reconfigures each instance to its permanent port.

SSH is disabled by default after post-install (modify /etc/gitea*/app.ini if needed).


Nginx Integration

The generated Gitea configuration file listens on port 80.
To enable HTTPS (port 443), use the example provided here.

Important

If you enable HTTPS, update /etc/giteaX/app.ini (ROOT_URL setting)
from http to https, then restart both Nginx and Gitea.

Note

The file also includes optional caching directives (commented out by default). You can enable them to improve load times and performance if needed. The lines you are looking for are at the bottom of the generated config file and look like this:

##### Cache js css static content and open files start #####################
# include /etc/nginx/nginxsnippets/cache-open-files.conf;
# include /etc/nginx/nginxsnippets/cache-statics.conf;
# include /etc/nginx/nginxsnippets/cache-js-css.conf;
##### Cache js css static content and open files stop ######################

Version Handling

This installer automatically checks the latest Gitea version from https://dl.gitea.com/gitea/version.json

If it fails, it falls back to the version number stored in the fallback file. That file contains one line, for example:

1.24.6

Why a separate file?
Keeping the fallback version outside the script avoids polluting the code with constants.
This keeps updates clean and ensures the installer logic never changes just because a version bump is needed.


Troubleshooting

Nginx fails to restart
Run nginx -t and review any syntax errors reported in /etc/nginx/conf.d/<domain>.conf.

Gitea front-end not loading
Run systemctl status gitea nginx and ensure both Gitea and Nginx services are active.

Access denied during database creation
Your MariaDB setup likely does not use socket authentication.
Re-run the installer with the -m flag (and optionally -a) to provide credentials.


FAQ

Q: Why doesnt the script ask for a MariaDB password by default?
A: Ubuntu 24.04s MariaDB installation defaults to socket authentication,
allowing the local root user to connect without a password.
The installer detects this automatically and skips password prompts when applicable.

Q: Can I run the installer multiple times?
A: Yes. Database and user creation use IF NOT EXISTS, making them safe to re-run.
Existing configuration files are replaced, but no data is deleted.

Q: Does this modify existing Nginx settings?
A: No. It adds a standalone host file in /etc/nginx/conf.d/
and validates configuration changes before applying them.
