Introduction

Sentrifugo is a FREE and powerful Human Resource Management System that can be easily configured to meet your organizational needs. Also It is a feature-rich and easily configurable application. It is written in PHP and uses MySQL/MariaDB to store its database. You can use Sentrifugo to track the employee’s performance, vacation dates, roles and privileges.

How Sentrifugo Works

Sentrifugo offers HR resource modules with exceptional features and an intuitive interface. It’s easy to set up, configure and use.

Installation

Just follow the steps below

Install Apache, start and enable it

dnf -y install httpd && systemctl start httpd && systemctl enable httpd

Install PHP with the following command

dnf install epel-release -y && rpm -Uvh http://rpms.remirepo.net/enterprise/remi-release-8.rpm && dnf install -y php-curl php-cli php-openssl php php-mbstring php-pear php-devel php-gd php-mysqli

Verify that php has been installed.

php -v

Edit the loaded PHP configuration file.

vim /etc/php.ini

Set an appropriate timezone.

date.timezone = Africa/Cairo
         #Replace "Africa/Cairo" with your appropriate timezone

Install MariaDB which is a fork of MySQL and start MariaDB then enable it to automatically start at boot time.

dnf install -y mariadb-server.x86_64 mariadb.x86_64 && systemctl start mariadb && systemctl enable mariadb

Secure MariaDB

mysql_secure_installation

Note

By default, there is no root password in MariaDB installation. Press the “Enter” key to proceed.Then set a strong password for the root user of your MariaDB server and answer “Y” to all of the other questions that are asked.

Log into mysql as a root with password you created.

mysql -u root -p

Provide the password for the MariaDB root then run the following queries.

CREATE DATABASE sentrifugo_db CHARACTER SET utf8 COLLATE utf8_general_ci;
CREATE USER 'sentrifugo_user'@'localhost' IDENTIFIED BY 'unixcopPassword';
GRANT ALL PRIVILEGES ON sentrifugo_db.* TO 'sentrifugo_user'@'localhost';
FLUSH PRIVILEGES;
\q;

So Install Sentrifugo HRM by downloading sentrifugo zip file.

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

Extract the archive then change the extracted file with sentrifugo then provide the appropriate ownership for it by running command below.

unzip Sentrifugo.zip -d /var/www/html/ && mv /var/www/html/Sentrifugo_* /var/www/html/sentrifugo && chown -R apache:apache /var/www/html/sentrifugo

Also allow HTTP traffic on port 80 on the firewall.

firewall-cmd --zone=public --permanent --add-service=http && firewall-cmd --zone=public --permanent --add-service=https && firewall-cmd --reload

Create a virtual host for your Sentrifugo HRM site.

vim /etc/httpd/conf.d/sentrifugo.unixcop.com.conf

Then add the following:

<VirtualHost *:80>
    ServerName sentrifugo.unixcop.com
    DocumentRoot /var/www/html/sentrifugo
    <Directory /var/www/html/sentrifugo>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Order allow,deny
        allow from all
    </Directory>
</VirtualHost>

Restart Apache.

systemctl restart httpd

You will need to finish the installation through the web interface. You can access the web installer by opening your browser then http://sentrifugo.unixcop.com

Note

As shown in above screenshot, there is an warning in the line 45 of PHPMailerAutoload.php file where the directive __autoload() is deprecated, So we will solve that with the recommended solution of Sentrifugo.

Edit the file with vim

vim /var/www/html/sentrifugo/install/PHPMailer/PHPMailerAutoload.php +45

Then add spl_autoload_register instead of __autoload() as shown in below screenshot.

Try to reload your Sentrifugo installer web page again, you will get the warning again then make sure that all prerequisites are marked green then click Next as shown below.
