How to Install TYPO3 on NixOS

TYPO3 is a free and open-source content management system that allows users to create and manage websites. NixOS is a Linux distribution that is designed to be highly secure and customizable. This tutorial will guide you through the steps to install TYPO3 on NixOS.

Prerequisites

Before we begin, make sure you have the following requirements:

A running NixOS system
A web server and database server installed (see our tutorials on how to install both Apache2 and MySQL on NixOS)
Basic knowledge of the command line

Step 1: Install TYPO3 on NixOS

Open a terminal and log in as the root user:

sudo su
Update the package list and install the TYPO3 package:
```
nix-channel --update
nix-env -iA nixos.typo3
```
Create a new database for TYPO3:
```
sudo mysql -u root -p
CREATE DATABASE typo3;
GRANT ALL PRIVILEGES ON typo3.* TO 'typo3user'@'localhost' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;
exit
```
This will create a new database named typo3 and a new user named typo3user with the password password. You can change these values to whatever you prefer.

Configure Apache to serve TYPO3

Create a new Apache configuration file for TYPO3 in the /etc/httpd/conf.d/ directory:

sudo nano /etc/httpd/conf.d/typo3.conf

Add the following content to the file:

Alias /typo3/ "/nix/store/<TYPO3_VERSION>/share/typo3/"
<Directory "/nix/store/<TYPO3_VERSION>/share/typo3/">
   Options Indexes FollowSymLinks MultiViews
   AllowOverride All
   Require all granted
</Directory>

DocumentRoot /nix/store/<TYPO3_VERSION>/share/typo3_src/
<Directory "/nix/store/<TYPO3_VERSION>/share/typo3_src/">
   Options Indexes FollowSymLinks MultiViews
   Require all granted
</Directory>

Replace <TYPO3_VERSION> with the version of TYPO3 you installed in Step 2 (tip: you can find the version in the /nix/store/ directory).

Save and close the file.

Restart Apache to apply the changes:
```
sudo systemctl restart httpd
```
Open a web browser and navigate to http://localhost/typo3/. You will be redirected to the TYPO3 install wizard.
Follow the on-screen instructions to complete the installation. Use the database credentials you created in Step 3 when prompted.

That's it! You have successfully installed TYPO3 on NixOS. You can now log in and start creating your website.
