How to Setup Mantis Bug Tracker on Debian 10

Mantis is one of the most popular web-based bug tracking systems used to track software defects. It also supports release and issues tracking for managing various releases of a project. Mantis is written in PHP and supports several databases including MySQL, PostgreSQL, and MS SQL. It comes with a lot of built-in tools that help you to collaborate with teams to resolve bugs easily from a web-based interface.

If you are looking for a self-hosted bug tracking system, then MantisBT is the best choice for you.

In this tutorial, we will show you how to install and configure the Mantis bug tracking system on Debian 10.

Step 1 – Install Nginx, MariaDB and PHP

First, you will need to install the Nginx web server, MariaDB, PHP and other PHP extensions to your server. You can install all required packages with the following command:

apt-get update -y
apt-get install nginx mariadb-server php php-fpm php-mysql php-cli php-ldap php-zip php-curl php 
php-cli php-mbstring php-xmlrpc php-soap php-gd php-xml php-intl php-pear php-bcmath unzip -y

After installing all the packages, tweak the PHP settings by editing the file php.ini:

nano /etc/php/7.3/fpm/php.ini

Change the following settings:

file_uploads = On
allow_url_fopen = On
short_open_tag = On
cgi.fix_pathinfo = 0
memory_limit = 512M
upload_max_filesize = 100M
max_execution_time = 300
max_input_vars = 1600
date.timezone = America/Chicago

Save and close the file when you are finished.

Step 2 – Configure MariaDB Database

Mantis uses MariaDB as a database backend, so you will need to create a database and user for Mantis.

First, log in to MariaDB with the following command:


Once logged in, create a database and user with the following command:

GRANT ALL PRIVILEGES ON mantis.* TO 'mantisuser'@'localhost' IDENTIFIED BY 'secure-

Next, flush the privileges and exit from the MariaDB shell with the following command:


Step 3 – Download MantisBT

First, visit the Sourceforge website and download the latest version of MantisBT with the following command:


Once the download is completed, unzip the downloaded file with the following command:


Next, move the extracted directory to the Nginx root directory with the following command:

mv mantisbt-2.24.1 /var/www/html/mantisbt

Next, set proper permissions and ownership to the mantisbt directory:

chown -R www-data:www-data /var/www/html/mantisbt
chmod -R 755 /var/www/html/mantisbt

Step 4 – Configure Nginx for MantisBT

Next, you will need to create an Nginx virtual host configuration file to host Mantis. You can create it with the following command:

nano /etc/nginx/sites-available/mantisbt

Add the following lines:

server {
listen 80;
root /var/www/html/mantisbt;
index index.php;

access_log /var/log/nginx/;
error_log /var/log/nginx/;

client_max_body_size 100M;

autoindex off;

location / {
index index.html index.php;
try_files $uri /index.php$is_args$args;

location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/var/run/php/php7.3-fpm.sock;
include fastcgi_params;
fastcgi_intercept_errors on;

Save and close the file, then enable the Mantis virtual host with the following command:

ln -s /etc/nginx/sites-available/mantisbt /etc/nginx/sites-enabled/

Next, verify Nginx for any syntax errors using the following command:

nginx -t

You should get the following output:

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

Finally, restart the Nginx service to apply the changes:

systemctl restart nginx
