To get started with installing Mantis, follow the steps below:

Step 1: Install Apache2 HTTP Server on Ubuntu

Apache2 HTTP Server is the most popular web server in use. so install it since Mantis needs it.

To install Apache2 HTTP on Ubuntu server, run the commands below.

sudo apt update
sudo apt install apache2

After installing Apache2, the commands below can be used to stop, start and enable Apache2 service to always start up with the server boots.

sudo systemctl stop apache2.service
sudo systemctl start apache2.service
sudo systemctl enable apache2.service

To test Apache2 setup, open your browser and browse to the server hostname or IP address and you should see Apache2 default test page as shown below. When you see that, then Apache2 is working as expected.

apache2 ubuntu install

Step 2: Install MariaDB Database Server

Mantis also needs a database server to store its content. and MariaDB database server is a great place to start when looking at open source database servers to use with Mantis.

To install MariaDB run the commands below.

sudo apt-get install mariadb-server mariadb-client

After installing MariaDB, the commands below can be used to stop, start and enable MariaDB service to always start up when the server boots.

Run these on Ubuntu

sudo systemctl stop mariadb.service
sudo systemctl start mariadb.service
sudo systemctl enable mariadb.service

After that, run the commands below to secure MariaDB server by creating a root password and disallowing remote root access.

sudo mysql_secure_installation

When prompted, answer the questions below by following the guide.

  • Enter current password for root (enter for none): Just press the Enter
  • Set root password? [Y/n]: Y
  • New password: Enter password
  • Re-enter new password: Repeat password
  • Remove anonymous users? [Y/n]: Y
  • Disallow root login remotely? [Y/n]: Y
  • Remove test database and access to it? [Y/n]:  Y
  • Reload privilege tables now? [Y/n]:  Y

Restart MariaDB server

To test if MariaDB is installed, type the commands below to logon to MariaDB server

sudo mysql -u root -p

Then type the password you created above to sign on. if successful, you should see MariaDB welcome message

Step 3: Install PHP 7.2 and Related Modules

PHP 7.2 may not be available in Ubuntu default repositories. in order to install it, you will have to get it from third-party repositories.

Run the commands below to add the below third party repository to upgrade to PHP 7.2

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:ondrej/php

Then update and upgrade to PHP 7.2

sudo apt update

Next, run the commands below to install PHP 7.2 and related modules.

sudo apt install php7.2 libapache2-mod-php7.2 php7.2-common php7.2-gmp php7.2-curl php7.2-intl php7.2-mbstring php7.2-xmlrpc php7.2-mysql php7.2-gd php7.2-xml php7.2-cli php7.2-zip

After installing PHP 7.2, run the commands below to open PHP default config file for Apache2.

sudo nano /etc/php/7.2/apache2/php.ini

Then make the changes on the following lines below in the file and save. The value below are great settings to apply in your environments.

file_uploads = On
allow_url_fopen = On
short_open_tag = On
memory_limit = 256M
upload_max_filesize = 100M
max_execution_time = 360
max_input_vars = 1500
date.timezone = America/Chicago

After making the change above, save the file and close out.

Step 4: Create Mantis Database

Now that you’ve install all the packages that are required, continue below to start configuring the servers. First create a Mantis database.

Run the commands below to logon to MariaDB. When prompted for a password, type the root password you created above.

sudo mysql -u root -p

Then create a database called mantis


Create a database user called mantisuser with new password

CREATE USER 'mantisuser'@'localhost' IDENTIFIED BY 'new_password_here';

Then grant the user full access to the mantis database.

GRANT ALL ON mantis.* TO 'mantisuser'@'localhost' WITH GRANT OPTION;

While still connected to MariaDB database server, use the steps below to allow MariaDB root user to connect from the app to the databases.

You’ll need the root account and password to setup Mantis. the steps below will disable plugin authentication for the root user.

use mysql;
update user set plugin='' where User='root';
flush privileges;

Restart and run the commands below to set a new password.

sudo systemctl restart mariadb.service

Step 5: Restart Apache2

After installing PHP and related modules, all you have to do is restart Apache2 to reload PHP configurations.

To restart Apache2, run the commands below

sudo systemctl restart apache2.service

To test PHP 7.2 settings with Apache2, create a phpinfo.php file in Apache2 root directory by running the commands below

sudo nano /var/www/html/phpinfo.php

sudo nano /etc/apache2/sites-available/mantis.conf

Then copy and paste the content below into the file and save it. Replace the highlighted line with your own domain name and directory root location.

<VirtualHost *:80>

     <Directory /var/www/mantis/>
        Options +FollowSymlinks
        AllowOverride All
        Require all granted

     ErrorLog ${APACHE_LOG_DIR}/error.log
     CustomLog ${APACHE_LOG_DIR}/access.log combined


Save the file and exit.
