What you need
I will show the installation on Ubuntu Server 20.04, but the tool can be installed on almost any Linux or Windows Server distribution. Outside of a running example of Linux, you also need a user with sudo privileges.
How to Download and Install OpManager
Installing OpManager is very easy. To do so, you need to first download the binary installer file. Log in to your Linux server and issue the command:
Once the file is downloaded, you need to grant it permissions with the command:
chmod u+x ManageEngine_OpManager_64bit.bin
With the permissions set, the installer will run with the command:
Because we work with a GUI-less server, you will receive a welcome from the text-based installer. It is very easy to use. Of course, after going through the EULA, accept the shortcomings for each question (Figure A.).
The only basic option that you might want to opt out of the default port is 8060. If that port is already in use, you will need to change it - otherwise, leave it as it is.
Once you have accepted all the errors, the installation will start and take about two to five minutes, depending on the speed of your network connection. When the installation is complete, you will get the completion tool back.
How to start OpManager
This is where most of your time is spent. The first time you start OpManager, it will take a while to complete.
Back at your destination window, switch to the OpManager bin directory with the command:
In that directory, issue the command:
This activity can take up to five minutes. When the startup is complete, it will give you the address and port used to connect to OpManager, which should be in the form http: // SERVER_IP: 8060 (where SERVER_IP is the IP address of the host server). Specify a web browser to that address and log in to OpManager with admin username and password admin (Figure B.).
You should find yourself on the main OpManager window, where you can start working with the tool (Figure C.).
How to start OpManager as a service
Once you have OpManager running, you will want to shut down and set the runtime setting to run as a service. Back at the terminal window, exit the running process with the keyboard shortcut Ctrl + c and then issue the command:
This will create a systemd startup file, so you can control OpManager with the commands:
sudo systemctl start OpManager sudo systemctl stop OpManager sudo systemctl enable OpManager
Once the service has started, you can log back in to the OpManager dashboard and you're good to go.
