# Install Icinga2 and Icingaweb2

{{>toc}}

### Installation (Master Node)

I followed this guide:

<http://linoxide.com/ubuntu-how-to/install-icinga2-ubuntu-16-04/>.

Here's where I deviated from the guide:

-   I installed nagios-plugins - but in Ubuntu 16.04 this has Samba as a

    dependency.  So then I also ran

    `apt remove samba-common samba-libs`.

-   I didn't install PHP 5.6 - Icingaweb2 is now PHP7-compatible.

-   I uncommented the second line in

    /etc/php/7.0/mods-available/zend-framework.ini, ran

    `phpenmod zend-framework` and restarted Apache (to work around this

    bug:

    <https://bugs.launchpad.net/ubuntu/+source/icingaweb2/+bug/1574250>

### Configuration

-   Run `icinga2 node wizard. `Select "N" to create a master node.

-   Enable the command module to allow issuing commands from Icingaweb2:

    `icinga2 feature enable command`; service icinga2 restart

-   Add an API user for remote checks.  For instance, a user that can

    receive backupninja checks:

    <div class="code panel pdl" style="border-width: 1px;">

    <div class="codeContent panelContent pdl">

    ``` 

    object ApiUser "backupninja" {

      password = "<redacted>"

      permissions = [

        {

          permission = "actions/process-check-result"

          filter = {{ match("backupninja", service.display_name) }}

        }

      ]

    }

    ```

### Install additional checks

#### Install Plugins

Place the following two scripts in your plugins directory

(`/usr/lib/nagios/plugins`) and ensure they're executable:

-   **check\_drupal** - installs with the Drupal "nagios" plugin, also

    available

    [here](http://cgit.drupalcode.org/nagios/plain/nagios-plugin/check_drupal?id=7da732e2d4943ec5368243f4cd2e33eb02769f23).

-   **check\_civicrm** - There are two scripts - one for Civi 4.6 and

    below, another for 4.7 and up.  4.7 version is available

    [here](https://github.com/PalanteJon/check_civicrm){.external-link},

    4.6 version is

    <span>[here](https://raw.githubusercontent.com/aghstrategies/com.aghstrategies.civimonitor/master/check_civicrm.php).</span>

-   <span>**check\_domain** - This does a WHOIS lookup to ensure domain

    names aren't about to expire.  Install from

    [here](https://raw.githubusercontent.com/glensc/monitoring-plugin-check_domain/master/check_domain.sh).</span>

-   <span><span>**check\_rbl** - Check spam blacklists.  File is

    [here](https://raw.githubusercontent.com/matteocorti/check_rbl/master/check_rbl), also install dependencies:

    `apt install libreadonly-xs-perl libnagios-plugin-perl libdata-validate-ip-perl libdata-validate-domain-perl libnet-dns-perl`

#### Define CheckCommand and Service objects for the new plugins

Copy the CheckCommand and Service files from

`icinga.jmaconsulting.biz:/etc/icinga2/zones.d/global-templates/CheckCommands`

and `icinga.jmaconsulting.biz:/etc/icinga2/conf.d/services`. See [[Add New Checks to Icinga2]] for details.

### Set up vim syntax highlighting on the Icinga2 server

```

mkdir -p ~/.vim/{syntax,ftdetect}

cd ~/.vim/syntax

wget https://raw.githubusercontent.com/Icinga/icinga2/master/tools/syntax/vim/syntax/icinga2.vim

cd ~/.vim/ftdetect

wget https://raw.githubusercontent.com/Icinga/icinga2/master/tools/syntax/vim/ftdetect/icinga2.vim

```
