# 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
```
