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 service to start 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

Disallow root login remotely? [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

Run the commands below to install PHP 7.1 and related modules.

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 lines below in the file and save.

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.

FLUSH PRIVILEGES;
EXIT;

Download Sentrifugo HRM Latest Release

cd /tmp && wget http://www.sentrifugo.com/home/downloadfile?file_name=Sentrifugo.zip -O Sentrifugo.zip
unzip Sentrifugo.zip
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/

     </Directory>

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

</VirtualHost>

Save the file and exit.

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
Jason
