Installing Sentrifugo HRMS on Ubuntu 20.04

Regarding PHP, ensure that the MySQL PDO as well as the GD libraries are installed. You can verify if these modules are already loaded by running the command  below;

php -m | egrep 'pdo_|gd'

If the modules listed above are not available, install them as shown below;

sudo apt install php-{mysql,gd}

Create a Database for Sentrifugo HRMS

Create a database that can be used to store Sentrifugo application data.

sudo mysql -u root -p
create database sentrifugo;

After that, you need to create a database user account for exclusive management of Sentrifugo. Be sure to grant this user all privileges on the Sentrifugo database;

grant all privileges on sentrifugo.* to hradmin@localhost identified by "PASSWORD";

Flush the database privileges to reload the database grant tables and exit the database;

flush privileges;

Download Sentrifugo application

Once your server has met the above per-requisites, go ahead and download the Sentrifugo application from Sentrifugo download page to your web root directory.

sudo wget -O /tmp/

Once the download completes, unzip it to your web root directory as shown below.

apt install zip -y

unzip /tmp/ -d /var/www/html/

This will extract Sentrifugo application to Sentrifugo_3.2 directory.

Rename this directory to sentrifugo and set the proper ownership and permissions for the application.

sudo mv /var/www/html/{Sentrifugo_3.2,sentrifugo}
sudo chown -R www-data.www-data /var/www/html/sentrifugo
sudo chmod -R 755 /var/www/html/sentrifugo

Create Sentrifugo Site Configuration

After you have installed Sentrifugo and set the proper permissions, create Apache site configuration for Sentrifugo application as shown below;

cat > /etc/apache2/sites-available/sentrifugo.conf << 'EOL'
<VirtualHost *:80>
     DocumentRoot /var/www/html/sentrifugo

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

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


Enable Sentrifugo site

a2ensite sentrifugo.conf

Enable rewrite module;

a2enmod rewrite

Set the correct timezone. Edit the file /etc/php/7.4/fpm/php.ini such that your configuration looks like;

sed -i 's/;date.timezone =/date.timezone = Asia\/Kolkata/' /etc/php/7.4/fpm/php.ini

Before you can restart Apache, verify that the configuration has no syntax errors;

apachectl -t
Syntax OK

If all is well, restart Apache

systemctl restart apache2

Configure Sentrifugo HRMS from Browser

Once you are done with the configuration above, it is time to configure Sentrifugo.

Most of the next configurations  will be done from the web interface. Therefore, navigate to the browser and enter the IP/hostname address of your server in order to access Sentrifugo.

While loading Sentrifugo on browser, you may get such an error;

Deprecated: __autoload() is deprecated, use spl_autoload_register() instead in /var/www/html/sentrifugo/install/PHPMailer/PHPMailerAutoload.php on line 45

Apply the suggested solution and restart Apache;

sed -i.bak '45s/__autoload/spl_autoload_register/' /var/www/html/sentrifugo/install/PHPMailer/PHPMailerAutoload.php
systemctl restart apache2
