It is recommended to install OpManager in the opt folder. By default, OpManager is installed in the /opt/ManageEngine/OpManager directory.
Troubleshooting steps:
Check if the DNS resolves properly to the IP Address on the system in which OpManager is installed. Add an entry to /etc/host file with ipaddress and host name if there is trouble starting OpManager.
This is a quick walk-through of the console mode installation of OpManager on a Linux box - an easy thing to do if you are working on a Windows box and want to install on a remote Linux system without a user interface.
Prerequisites:
To begin with, make sure you have downloaded the binary for Linux.

Before installing the product, please check for the 'execute' permission in the /tmp directory with the 'mount' command. If the command returns the line containing /tmp as 'noexec' as highlighted below, it depicts that we aren't allowed to execute any file under the /tmp directory [even if the /tmp directory has 777 permission(i.e. rwxrwxrw)] due to which our installation might throw errors.
[root@ip-172-31-44-74 /]# mount | grep /tmp
tmpfs on /tmp type tmpfs (rw,nosuid,nodev,noexec,seclabel)
In such a case, we can go ahead with one of the below approaches:
a) Modify the 'noexec' permission in the /tmp directory to 'exec'.
To modify the permission in the /tmp directory, we would have to remount the directory with 'exec' permission with the below command:
mount -o remount,exec /tmp
b) Use another directory as temp directory for installation:
To use another directory as temp directory for the installation, we would have to create a tmp directory under any directory (preferrably /opt since it would have full access) and then mark it as temp before installing the product with the below commands:
mkdir /opt/tmp
export IATEMPDIR=/opt/tmp
[Note: If the 1st approach is being followed, it is best that we remount the tmp directory with noexec permission once the installation completes successfully and verifying that the product is functional. Changing the tmp directory to executable might be vulnerable since the directory has world wide access (777 - rwxrwxrw) by default. The permission can be revoked with the below command:
mount -o remount,noexec /tmp
As for the 2nd approach, the IATEMPDIR is just an environmental variable and the change will be reverted once that particular terminal is closed.]
Post performing the above, please proceed with the installation of OpManager.
Note: The above mentioned steps have been carried out in Red Hat Enterprise Linux 7 OS with hardening level of CIS Benchmark - Level 1 machine.
Steps for starting the setup as a service:
1. Install the product
2. Go to > <OpManager Home>/bin/
3. run the linkAsService.sh file by (sh linkAsService.sh)
4. Then start the product
systemctl start OpManager.service (or) /etc/init.d/OpManager.service
