To install OrangeHRM you’ll only need a CentOS 7 server and root privileges over it if you are logged in as non root user then run sudo -i command to switch to root user. Follow this guide to install OrangeHRM on your CentOS 7 server.
Updating System
It is highly recommended to update your system and upgrade the available packages so please run the below shown command it’ll do the job for you.yum -y update
Installing Apache Web Server
Once the system is updated, you can install the dependencies required. To install OrangeHRM you will need to install the Apache web server along with MaraiDB and PHP with a few extensions.
Run the following command to install the Apache web server.
yum -y install httpd
Now you can start Apache and enable it to start at boot time, using the following commands.
systemctl start httpd.service systemctl enable httpd.service
You can check the status of Apache web server using the following command.

We will need to install MariaDB for database purposes for OrangeHRM. MariaDB 5.5 is shipped in the default CentOS 7 repository, so just run this command to install MariaDB.
yum -y install mariadb-server
Now you’ll have to start the MariaDB service and enable it to start at the boot time like we have done before for apache server, to do so please run following command.
systemctl start mariadb.service systemctl enable mariadb.service
You can check status of mariaDB using this command and you should see following output.
systemctl status mariadb.service
[root@ip-172-31-21-184 ~]# systemctl status mariadb.service

We will have to make sure that this installation is secure and to do so run following command.
mysql_secure_installation
You’ll be asked to provide root password so enter appropriate password and answer yes to all questions by pressing Y.
Now you’ll have to create a database for OrangeHRM please follow the instructions.
mysql -u root -p
You’ll be asked to enter password so simply enter a password and now execute the following queries to create a new database.
CREATE DATABASE orangehrm;
The above query will create a database named orangrhrm. For the database you can use any name you prefer in the place of orangehrm. Make sure that you use semicolon at the end of each query as a query always ends with a semicolon. Once the database is created you can create a new user and grant the required permissions to the user for the database.
CREATE USER 'orangehrm_user'@'localhost' IDENTIFIED BY 'StrongPassword';
The above query will create a user with username orangehrm_user. You can use any preferred username instead of orangehrm_user. Replace StrongPassword with a strong password.
Now provide the appropriate privileges to your database user over the database you have created. Run the following query to do so.
GRANT ALL PRIVILEGES ON orangehrm.* TO 'orangehrm_user'@'localhost';
Now run the following query to immediately apply the changes on the database privileges.
FLUSH PRIVILEGES;
Now you can exit from MariaDB prompt using following command.\q.
We will have to install PHP. To do so run following commands as shown below.
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpmrpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
Now use this command to install PHP 5.6 and required extensions.
yum install php56w php56w-opcache
Next you’ll have to restart your apache web server to load new components that we just configured and use following command to restart apache web server.
systemctl restart httpd.service
Installing OrangeHRM
Once we have installed all the dependencies required to install orangeHRM now let’s download and install latest version of orangeHRM available. First go to the web root directory /var/www/html then download the orangeHRM as shown below commands.
cd /var/www/html
If in case you don’t have wget package and unzip package installed on your system then you can install them using yum -y install wget unzip.
wget http://nchc.dl.sourceforge.net/project/orangehrm/stable/3.3.2/orangehrm-3.3.2.zip
unzip orangehrm-3.3.2.zip
Move all the files from orangehrm directory to your current working directory using below given command.
mv orangehrm-3.3.2/* . && mv orangehrm-3.3.2/.htaccess .
Next you’ll have to set proper ownership permissions and you can do so using this underneath command.
chown -R apache:apache /var/www/html
Next we will have to edit MariaDB configuration file. You can use any text editor to edit configuration file here we are using nano text editor. If in you don’t have nano editor you can install it using yum -y install nano.
Now run below shown command to edit the MariaDB configuration file.
nano /etc/my.cnf
Under the [mysqld] block please place the following line: event_scheduler = ON and then restart the MariaDB to apply the changes.
systemctl restart mariadb
Next we will have to edit the apache web server configuration file using any text editor so open the apache configuration file and to do so underneath command will do the job.
nano /etc/httpd/conf/httpd.conf
Please find the line ‘AllowOverride None‘ and change it to ‘AllowOverride All‘, save the file and exit from text editor. This will enable .htaccess files to be used by your web browser. Now restart the apache web server to apply changes that we have just made.
systemctl restart httpd
Next you’ll have to modify firewall rules and if in case you don’t have firewalld services installed on your server then you can install it using yum -y install firewalld and you can start it using systemctl start firewalld
Next run these below given command to modify the firewalld rules.
firewall-cmd --zone=public --permanent --add-service=httpfirewall-cmd --reload
Now disable SELinux temporarily using this below given command.
setenforce 0
