iTOP is a simple, Open source web based IT Service Management tool. It has all of ITIL functionality that includes with Service desk, Configuration Management, Incident Management, Problem Management, Change Management and Service Management. iTop relays on Apache/IIS, MySQL and PHP, so it can run on any operating system supporting these applications. Since iTop is a web based application you don’t need to deploy any client software on each user’s PC. A simple web browser is enough to perform day to day operations of an IT environment with iTOP.To install and configure iTOP we will be using CentOS 7 as base operating with basic LAMP Stack environment installed on it that will cover its almost all prerequisites.
iTop download package is present on SourceForge, we can get its link from their official website link.
We will the download link from here and get this zipped file on server with wget command as below.
[root@centos-007 ~]# wget http://downloads.sourceforge.net/project/itop/itop/2.1.0/iTop-2.1.0-2127.zip
By using unzip command we will extract the downloaded packages in the document root directory of our apache web server in a new directory with name itop.
[root@centos-7 ~]# ls
iTop-2.1.0-2127.zip
[root@centos-7 ~]# unzip iTop-2.1.0-2127.zip -d /var/www/html/itop/
List the folder to view installation packages in it.
[root@centos-7 ~]# ls -lh /var/www/html/itop/

Here is all the extensions that we can install.
[root@centos-7 2.x]# ls
authent-external itop-backup itop-config-mgmt itop-problem-mgmt itop-service-mgmt-provider itop-welcome-itil
authent-ldap itop-bridge-virtualization-storage itop-datacenter-mgmt itop-profiles-itil itop-sla-computation version.xml

itop-attachments itop-config itop-knownerror-mgmt itop-service-mgmt itop-virtualization-mgmt
Now from the extracted web directory, moving through different data models we will migrate the required extensions from the datamodels into the web extensions directory of web document root directory with copy command.
[root@centos-7 2.x]# pwd
/var/www/html/itop/web/datamodels/2.x
[root@centos-7 2.x]# cp -r itop-request-mgmt itop-service-mgmt itop-service-mgmt itop-config itop-change-mgmt /var/www/html/itop/web/extensions/
Most of our server side settings and configurations are done.Finally we need to complete its web interface installation process to finalize the setup.
