Install Apache2 HTTP Server

Sentrifugo HRM requires a web server, and the most popular web server in use today is Apache2. So, go and install Apache2 on Ubuntu by running the commands below:

sudo apt update
sudo apt install apache2

Next, run the commands below to stop, start and enable the Apache2 service to always start up with the server boots.

sudo systemctl stop apache2.service

sudo systemctl enable apache2.service

Install MariaDB

Sentrifugo HRM also requires a database server. And MariaDB database server is a great place to start. To install it, run the commands below.

sudo apt-get install mariadb-server mariadb-client

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

Run these on Ubuntu 16.04 LTS

sudo systemctl stop mysql.service
sudo systemctl start mysql.service
sudo systemctl enable mysql.service

Run these on Ubuntu 17.10 and 18.04 LTS

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

After that, run the commands below to secure the 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

sudo systemctl restart mysql.service

Install PHP 7.2 FPM and Related Modules

PHP 7.1 isn’t available on Ubuntu default repositories… 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

sudo apt install php7.2 php7.2-common php7.2-mbstring php7.2-xmlrpc php7.2-soap php7.2-gd php7.2-xml php7.2-intl php7.2-mysql php7.2-cli php7.2 php7.2-ldap php7.2-zip php7.2-curl

After installing PHP, run the commands below to open the FPM PHP default file.

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

Then change to the following lines below in the file and save.

file_uploads = On

Then create a database called sentrifuso


Create a database user called sentrigufouser with a new password

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

Then grant the user full access to the database.

GRANT ALL ON sentrifugo.* TO 'sentrifugouser'@'localhost' IDENTIFIED BY 'user_password_here' WITH GRANT OPTION;

Finally, save your changes and exit.


Download Sentrifugo HRM Latest Release

Next, visit the SentrifugoHRM site and download the latest version.

After downloading, run the commands below to extract the download file into the Apache2 root directory.

cd /tmp && wget -O
sudo mv Sentrifugo_3.2 /var/www/html/sentrifugo

Then run the commands below to set the correct permissions for Concrete5 to function.

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

Configure Apache2

Finally, configure the Apahce2 site configuration file for Sentrifugo HRM. This file will control how users access Sentrifugo HRM content.

Run the commands below to create a new configuration file called centrifugal.conf.

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

        AllowOverride All
        Require all granted

     ErrorLog ${APACHE_LOG_DIR}/error.log

I love computers; maybe way too much. What I learned I try to share at


  1. Hi Richard,

    I am hoping you may be able to answer my question or maybe know someone that can, I work for a small charity in London and we have looked into a HRMS, and came across Sentrifugo which suits us perfectly, sadly it no longer is supported but can download for free, I have had our external It, install it and have come up with the configuration screens and the database settings, i am unsure of what to do and may need some hand holding, i saw how you suggest we create a database but have never done this and our IT company are reticent to do this, wondering if you or you know someone that might be able to walk us through this step and hopefully get us up and running.

    With best regards

  2. Hi Richard,

    This STOP WORK with php 8.0, anyone know how to deal with?
