  • A Vultr CentOS 7 server instance with at least 2GB RAM.
  • A sudo user.

For this tutorial, we will use as the domain name pointed towards the Vultr instance. Please make sure to replace all occurrences of the example domain name with the actual one.

Update your base system using the guide How to Update CentOS 7. Once your system has been updated, proceed to install the dependencies.

Install Apache

Install Apache.

sudo yum -y install httpd

Start Apache and enable it to automatically run at boot time.

sudo systemctl start httpd
sudo systemctl enable httpd

Install PHP 5.6

Add and enable the Remi repository as PHP version 5.6 is not available by default in the yum repository.

sudo rpm -Uvh
sudo yum -y install yum-utils
sudo yum-config-manager --enable remi-php56

Install PHP version 5.6 along with the modules required by Sentrifugo HRM.

sudo yum -y install php php-gd php-mysqli php-mbstring php-curl php-cli php-pear php-devel php-openssl

Edit the loaded PHP configuration file.

sudo nano /etc/php.ini

Find the following line. Uncomment and set appropriate timezone.

date.timezone = Asia/Kolkata
;Replace "Asia/Kolkata" with your appropriate timezone

memory_limit = -1

Install MariaDB

MariaDB is a fork of MySQL. Add the MariaDB repository into your system. The default yum repository contains an older version of MariaDB.

echo "[mariadb]
name = MariaDB
baseurl =
gpgcheck=1" | sudo tee /etc/yum.repos.d/mariadb.repo

Install MariaDB.

sudo yum -y install mariadb mariadb-server

Start MariaDB and enable it to automatically start at boot time.

sudo systemctl start mariadb
sudo systemctl enable mariadb

Before configuring the database, you will need to secure MariaDB first.

sudo mysql_secure_installation

You will be asked for the current MariaDB root password. By default, there is no root password in a fresh MariaDB installation. Press the "Enter" key to proceed. Set a strong password for the root user of your MariaDB server and answer "Y" to all of the other questions that are asked. The questions asked are self-explanatory.

Log into the MySQL shell as root.

mysql -u root -p

Provide the password for the MariaDB root user to log in.

Run the following queries to create a database and a database user for the Sentrifugo installation.

CREATE DATABASE hrm_data CHARACTER SET utf8 COLLATE utf8_general_ci;
CREATE USER 'hrm_user'@'localhost' IDENTIFIED BY 'StrongPassword';
GRANT ALL PRIVILEGES ON hrm_data.* TO 'hrm_user'@'localhost';

You can replace the database name hrm_data and username hrm_user according to your choice. Please make sure to change StrongPassword to a very strong password.

Install Sentrifugo HRM

Download the Sentrifugo HRM zip archive.

wget -O

Install unzip.

sudo yum -y install unzip

sudo unzip -d /var/www

Change the name of the directory and provide the appropriate ownership.

cd /var/www
sudo mv Sentrifugo_*/ sentrifugo/
sudo chown -R apache:apache /var/www/sentrifugo

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