It comes with a performance appraisal module which helps the HR managers track the performance of the employee over time. It contains numerous features which are required for day to day employee management, such as employee self-service, powerful analytics, easy background checks, leave management, expenses, and asset management.
- A AKLWEB Host Dedicated Server Or VPS Server with at least 2GB RAM.
- A sudo user.
For this tutorial, we will use
hrm.example.com as the domain name pointed towards the Dedicated Server. 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.
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
sudo rpm -Uvh http://rpms.remirepo.net/enterprise/remi-release-7.rpm 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
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 = http://yum.mariadb.org/10.2/centos7-amd64 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck=1" | sudo tee /etc/yum.repos.d/mariadb.repo
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.
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'; FLUSH PRIVILEGES; EXIT;
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.
