A Comprehensive Guide For TYPO3 CMS Setup on Debian 12

You need some requirements to complete the TYPO3 CMS installation on Debian 12. Let’s see what we need.


You must have access to your server as a non-root user with sudo privileges and set up a basic firewall. For this purpose, you can visit the Debian 12 Initial Setup Guide.

Because we want to install TYPO3 with LAMP stack, you must install it on your server. To do this, you can visit the LAMP Stack Setup on Debian 12.

Also, you need a domain name that is pointed to your server’s IP address.

When you are done, follow the steps below to complete the TYPO3 CMS Setup on Debian 12.

Step 1 – PHP Configuration For TYPO3 CMS

At this point, we assumed that you have installed Apache, MariaDB, and PHP from the requirements. Now you must install some PHP extensions on Debian 12:

sudo apt install libapache2-mod-php php-cli php-common php-gmp php-curl php-mysql php-json php-intl php-mbstring php-xmlrpc php-gd php-xml php-zip php-imap -y

Then, you must use your favorite text editor to open the php.ini file like Vi Editor or Nano Editor:

sudo vi /etc/php/8.2/apache2/php.ini

In the file look for the following directives and change their value as shown below:

max_execution_time = 240

memory_limit = 256M

upload_max_filesize = 100M

post_max_size = 100M

max_input_vars = 1500

date.timezone = Etc/UTC

When you are done, save and close the file.

Next, restart Apache to apply the changes:

sudo systemctl restart apache2

Step 2 – Configure Database User For TYPO3 CMS

At this point, you must create a TYPO3 database and user. To do this, log in to your MariaDB shell with the command below:

sudo mysql -u root -p

Then, from your MariaDB shell run the commands below to create the TYPO3 database, and user database, grant privileges, and exit from your shell:

MariaDB [(none)]> CREATE DATABASE typo3db; 
MariaDB [(none)]> CREATE USER 'typo3user'@'localhost' IDENTIFIED BY 'strongpassword'; 
MariaDB [(none)]> GRANT ALL PRIVILEGES ON typo3db.* TO 'typo3user'@'localhost'; 
MariaDB [(none)]> FLUSH PRIVILEGES; 
MariaDB [(none)]> EXIT;

Step 3 – Download the Latest TYPO3 CMS From Source on Debian 12

At this point, you need to visit the TYPO3 downloads page and get the latest version by using the following wget command under the /tmp directory:

# cd /tmp
# sudo wget --content-disposition

Then, extract your downloaded file in the /var/www/html directory by using the command below:

sudo tar -xvzf typo3_src-12.4.11.tar.gz -C /var/www/html

Next, switch to your web root directory and rename your TYPO3 file with the command below:

# cd /var/www/html 
# sudo mv typo3_src-12.4.11 /var/www/html/typo3

Now you can create a file on your web root directory for a fresh installation of TYPO3:

sudo touch /var/www/html/typo3/FIRST_INSTALL

Set the correct ownership for your TYPO3 and set the correct permissions on Debian 12 with the commands below:

# sudo chown -R www-data:www-data /var/www/html/typo3
# sudo chmod -R 755 /var/www/html/typo3

Step 4 – Apache Configuration for TYPO3 CMS

At this point, you need to create an Apache virtual host for TYPO3 by using the command below:

sudo vi /etc/apache2/sites-available/typo3.conf

Add the below content to the file with your valid domain name:

<VirtualHost *:80>
     ServerAdmin [email protected]
     DocumentRoot /var/www/html/typo3

     <Directory /var/www/html/typo3/>
          Options FollowSymlinks
          AllowOverride All
          Require all granted

     ErrorLog ${APACHE_LOG_DIR}/typo3_error.log
     CustomLog ${APACHE_LOG_DIR}/typo3_access.log combined

When you are done, save and close the file.

Then, disable the default Apache configuration file with the following command:

sudo a2dissite 000-default.conf

Activate your TYPO3 CMS virtual host file on Debian 12 by using the command below:

sudo a2ensite typo3.conf

Finally, enable the Apache rewrite module and restart the Apache service to apply the changes:

# sudo a2enmod rewrite
# sudo systemctl restart apache2

Note: Remember to allow HTTP traffic through your UFW firewall:

# sudo ufw allow http
# sudo ufw reload
