Short Description

The MintHCM Installing Guide is a technical document that provides detailed instructions on how to install and configure the software.

The guide covers everything from system requirements to database configuration and user setup. It is a comprehensive technical resource that provides you with the information you need to set up and configure the software effectively.


To run MintHCM, your system must have PHP 7.1 and MySQL 5.6-5.7 or MariaDB 10 installed. Other versions are not supported!

MintHCM is compatible with Chromium, Firefox, and Edge web browsers. Unfortunately, we do not support IE, but you can still test and use it by yourself.

  1. Download MintHCM zip file from
  2. Copy the zip file to your server
  3. Unzip it in the directory of your choice
  4. Change files permissions in that directory accordingly with your platform demands

For Ubuntu Linux/Apache it will be:

cd ../<yourMintHCMdirectory>
sudo chown -R www-data:www-data *
sudo chmod -R 755 *

where www-data are default user and group for Ubuntu Linux/Apache. However, it might have been changed on your server. Use the actual system user and group.

It's important to set up a Crontab to allow MintHCM to run background tasks on your server. Edit your web server user's crontab file after the installation is completed.

To do so, you have to edit your web server user's crontab file. You can open it with a command:

sudo crontab -e -u www-data (or another actual user)

Now you have to add the following line to the crontab file:

*    *    *    *    *     cd /var/www/MintHCM/MintHCM; php -f cron.php > /dev/null 2>&1

Information about Crontab edition may be also found in Schedulers in Administration panel of MintHCM after installation.

Note that Windows or other systems have different background processes mechanisms.

4. Enter basic database configuration and administrator user data on the next screen.

If the database and MintHCM are on the same server, enter 'localhost' in the Host Name field. If the database is on a different server, enter the hostname or IP address of the database server in the Host Name field.

There is a known bug with MySQL related to MyISAM, the UTF8 character set and indexes that you can check here.


  • Make sure MySQL is configured with the InnoDB storage engine.
  • Change the storage engine used by default so that new tables will always be created appropriately:
set GLOBAL storage_engine='InnoDb';
  • For MySQL 5.6 and later, use the following:
SET GLOBAL default_storage_engine = 'InnoDB';
