Installation

Prerequisites

  • The individual performing this installation has a small bit of Linux experience.
  • Root access is available.
  • Internet access is required for installing any missing but required software packages.
  • NMIS must be installed on the same server that opConfig is being installed on.
  • opConfig requires a working MongoDB installation (but not necessarily on the same server)
  • You will need a license for opConfig (evaluation licenses are available here).

Preparation

  • If you do not have a MongoDB installation yet, please follow the instructions in the MongoDB Installation Guide.
    opConfig does not require any specific MongoDB setup, but you will have to provide opEvents with the correct MongoDB server information, database name and user name/password (if you use authentication). opConfig works best with the default database name "nmis", and with MongoDB authentication enabled.

  • If you do not yet have a working installation of NMIS in your server, please follow the procedure in the NMIS 8 Installation Guide.
  • Download opConfig from the Opmantek website.

Installation Steps

Transfer the opConfig tarball onto the server in question, either by direct download from the Opmantek website, or from your desktop with scp or sftp or a similar file transfer tool.

Make a record of where you put the tarball (root's home directory or /tmp are good locations).

  • Become root and unpack the tarball:

    # become root
sudo sh
# if the tarball was saved in a different location, adjust the following command 
cd
tar xzf opConfig-Linux-x86_64-2.0.0.tgz

  • Start the interactive installer and follow its instructions:

    sudo sh
cd opConfig-2.0.0/
./installer

This installer will install opConfig into /usr/local/omk.
To select a different installation location please rerun the 
installer with the -t option.

  • The installer will interactively guide you through the steps of installing opConfig. Please make sure to read the on-screen prompts carefully.
  • When the installer finishes, opConfig is installed into /usr/local/omk, and the default configuration files are in /usr/local/omk/conf, ready for your initial config adjustments.
  • A detailed log of the installation process is saved as /usr/local/omk/install.log, and subsequent upgrades or installations of other Opmantek products will add to that logfile.
  • For detailed information about the interactive installer please check the Opmantek Installer page.

Initial Configuration

  • You may need to adjust the MongoDB-related settings:
    open conf/opCommon.nmis in an editor, go to the database section and change the server, username and password to reflect your MongoDB installation.
    The result should look similar to the following (but there might be extra settings related to other products):
'database' => {
  'db_server' => 'localhost',
  'db_port' => '27017',
  'db_name' => 'nmis',
  'db_username' => 'opUserRW',
  'db_password' => 'op42flow42',
},
  • Access the opConfig GUI and enter your license.
    The opConfig GUI is accessible at http://<yourservername or ip address>/omk/opConfig/, and until you have entered a valid license neither the opConfig GUI nor the CLI tools will operate.

  • Setup Cron to perform the desired opConfig data collection periodically
    opConfig's CLI tool opconfig-cli.pl is responsible for performing such operations, and you should familiarize yourself with its capabilities: simply start it without any arguments, like this:

    # you should generally run opconfig-cli.pl as root
sudo /usr/local/omk/bin/opconfig-cli.pl

opconfig-cli.pl Version 1.2.4
...
usage: 
        opconfig-cli.pl act={discover|test_connect} node=nodeX
        opconfig-cli.pl act=import_from_nmis [nodes=nodeA,nodeB...
        opconfig-cli.pl act=run_command_sets [nodes=nodeA,nodeB...] [tags=tagA,tagB...]
...

    To perform periodic config collections, you should run opconfig-cli.pl act=run_command_sets from cron. You can set this up either using crontab -e (as root), or by creating a cron 'snippet file' in /etc/cron.d/ - Check your cron documentation for details about system-wide cron files.

    Here is an example cron snippet called /etc/cron.d/opConfig:

    # opConfig: hourly command set running 
1 * * * * 	root 	/usr/local/omk/bin/opconfig-cli.pl quiet=1 act=run_command_sets tags=HOURLY >/dev/null
# and the daily ones
7 7 * * * * root 	/usr/local/omk/bin/opconfig-cli.pl quiet=1 act=run_command_sets tags=DAILY >/dev/null
# and a daily import from open-audit enterprise 
21 4 * * * root 	/usr/local/opmojo/bin/opconfig-cli.pl quiet=1 act=import_audit
