Installation Guide - Debian Linux

Before you start

  • This page details manually installing Opsview on a Debian platform. Note that we recommend using our automated installation method instead.
  • For supported Debian releases please refer to platforms.
  • When planning your system please see our design notes for further information on planning for separate database servers, disk partitioning and security.

Preparation

Prerequisites

See the installation prerequisites information to set up users, groups and MySQL.

Importing repository signatures

For security, this repository is PGP signed. Follow our instructions to add the key to your server.

If you do not import our PGP keys, you could see errors such as:

W: GPG error: https://downloads.opsview.com squeeze Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY FB4C675977CB2CF6

The “NO_PUBKEY” portion of this message indicates that your system does not have the public key for this repository and so cannot verify its contents. You can ignore these warnings and import the keys later.

You could also see:

WARNING: The following packages cannot be authenticated!
  opsview-perl opsview-base libapache2-mod-auth-tkt-prefork-opsview opsview-core opsview-web opsview
Install these packages without verification [y/N]?

You can continue, though we recommend you verify the packages.

Opsview repositories

To install Opsview, create a new file - /etc/apt/sources.list.d/opsview.list. See our repositories page for more information.

Updating the package lists

When configuration is complete, update the repository information: sudo apt-get update

Troubleshooting

Note: If you get the error:

E: The method driver /usr/lib/apt/methods/https could not be found.

This means that you do not have the required transport methods installed. You will need to install apt-transport-https: sudo apt-get install apt-transport-https

Installation

Once the sources list has been updated to include the Opsview apt repository, the latest release of Opsview can be installed by running the following command as root.

sudo apt-get install opsview

You may get prompted for the MySQL root user password. This is required to set up the databases used by Opsview.

You may get prompted to make mrtg.cfg root only. Reply yes.

Next, run the following command, as root, to complete the installation

/usr/local/nagios/installer/postinstall_root -p <MYSQL_ROOT_PASSWORD> -h <MYSQL_HOST> -P <MYSQL_PORT>

The Opsview server is now listening on port 3000, eg. http://opsview.example.com:3000/. Confirm that this works correctly before configuring Apache.

Using Apache as a proxy server

The performance of Opsview will be significantly improved by using Apache at the front end. All the following commands should be run as root.

sudo cp /usr/local/nagios/installer/apache_proxy.conf /etc/apache2/sites-available/opsview
sudo a2ensite opsview
sudo a2dissite default

You will also need to install the Apache proxy_html module in order to use this configuration:

sudo apt-get install libapache2-mod-proxy-html
sudo a2enmod proxy_http

Now Apache can be restarted: sudo /etc/init.d/apache2 force-reload

You can now access Opsview at http://opsview.example.com/ (for example).

You will need to activate your copy of Opsview. See our activation documentation.

Logging in

Once Opsview has been installed, a single administrative user will have been created. The credentials for this user are:

Username Password
admin initial

You should change this password to prevent unauthorised access to Opsview. This can be done from the Administrator link at the top right of the page.

Check out our quick start guide to help you get familiar with Opsview.

Troubleshooting

MRTG emails due to permissions

NOTE: There might be a bug in the MRTG package which may cause a warning email to be sent to the system administrator every 5 minutes. This can be fixed by running sudo mkdir /var/www/mrtg

See this and this bug report for more information.

SNMP MIBs missing

On Debian Squeeze, SNMP MIBs are not installed by default.

You will need to install the SNMP MIBs manually with: apt-get install snmp-mibs-downloader

See Debian's SNMP page for more information (the package is in the non-free repository).

Note, you may still get some MIB reading errors. For example:

$ snmpwalk -mALL -v2c -cpublic host | head
