If you like to have your own piece of paper, we have a more detailed installation manual in English (Translation credit goes to Wolfgang) and German for the latest release:



Note: Upgrades from NagiosQL 1.x and 2.x are not possible, you should better start at "New Installation" and after the installation is done, import Nagios configuration files with NagiosQL.

To upgrade from NagiosQL 3.x, please follow the steps below:

  1. Backup your existing database!
  2. Download and extract NagiosQL 3.2 to a NEW directory within your Apache Document Root (don't replace your old files!).
  3. Move your old config/settings.php file to the newly installed NagiosQL config/ folder
  4. Start the Installation Wizard by opening install/index.php
  5. Switch to your preferred language (see Appendix) and follow the instructions

Important information: If you just moved the new version to the same directory as the old version, please always restart your webserver to make sure sessions are really cleared.

New Installation


The NagiosQL translation depends on gnu-gettext and this framework depends on your locale system settings. Make sure you have the appropriate locale installed on your system (e.g. en-GB.utf-8). Please verify that by executing "locale -a".


Download and extract

Download the latest NagiosQL Version from and extract the nagiosql-*.tar.gz to a directory accessible by your webserver (e.g. /srv/www/htdocs). A subdirectory "nagiosql" will be created:

cd /srv/www/htdocs/
cp nagiosql-*.tar.gz /srv/www/htdocs/
tar zxvf nagiosql-*.tar.gz


Directory Structure

It is recommend to have the following directory structure (you can change the directory names in your NagiosQL Domain Configuration):

/etc/nagiosql/ 			                -> Common configuration files
   	"            /hosts			-> Host configuration files
	"            /services			-> Service configuration files
	"            /backup/			-> Backups of the common configuration files
	"	        "      /hosts		-> Backups of the host configuration files
	"	        "      /services	-> Backups of the service configuration files


In order to find the configuration files generated by NagiosQL your Nagios configuration must be amended, too. You are free to change the directory names, but be sure to do that in both configuration files (Nagios: nagios.cfg, NagiosQL: Domain Administration). The directory structure (e.g. backup directories below main directories) should never be changed!

The Nagios configuration file nagios.cfg should be amended to follow the above recommendation. To get it working, replace all existing cfg_dir and cfg_file definitions in your nagios.cfg by:

## Timeperiods
## Commands
## Contacts
## Hosts
## Services


The following file permissions are required to let NagiosQL read and write the Nagios configuration files. In our example the Apache runs as user "www-data" and the group "www-data" as well as Nagios runs by the user "nagios" and the group "nagios". Instead of the below configuration, you could also add the Apache user to the Nagios group. The configuration files are located at /etc/nagiosql. Please amend if this differs from your installation.

## Nagios Main Configuration Files
chgrp www-data /etc/nagios
chgrp www-data /etc/nagios/nagios.cfg
chgrp www-data /etc/nagios/cgi.cfg
chmod 775 /etc/nagios
chmod 664 /etc/nagios/nagios.cfg
chmod 664 /etc/nagios/cgi.cfg

## NagiosQL Configuration
chmod 6755 /etc/nagiosql chown www-data.nagios /etc/nagiosql chmod 6755 /etc/nagiosql/hosts chown www-data.nagios /etc/nagiosql/hosts chmod 6755 /etc/nagiosql/services chown www-data.nagios /etc/nagiosql/services ## NagiosQL Backup Configuration chmod 6755 /etc/nagiosql/backup chown www-data.nagios /etc/nagiosql/backup chmod 6755 /etc/nagiosql/backup/hosts chown www-data.nagios /etc/nagiosql/backup/hosts chmod 6755 /etc/nagiosql/backup/services chown www-data.nagios /etc/nagiosql/backup/services ## Amend already existing files chmod 644 /etc/nagiosql/*.cfg chown www-data.nagios /etc/nagiosql/*.cfg
chmod 644 /etc/nagiosql/hosts/*.cfg chown www-data.nagios /etc/nagiosql/hosts/*.cfg chmod 644 /etc/nagiosql/services/*.cfg chown www-data.nagios /etc/nagiosql/services/*.cfg

## The Nagios binary must be executable by the Apache user:
chown nagios.www-data /usr/sbin/nagios chmod 750 /usr/sbin/nagios

Be sure the Apache user is able to write the Nagios commandfile. Please check your nagios.cfg for the correct path to the commandfile!

chown /usr/local/nagios/var/rw/nagios.cmd
chmod 660 /usr/local/nagios/var/rw/nagios.cmd

Verify Installation and Configuration

Please execute as the webserver user "nagios -v /etc/nagios/nagios.cfg" and check for additional permissions.

Running NagiosQL

Now you should be able start NagiosQL: http://www.domain.tld/nagiosql/
The Installation Wizard will help you installing NagiosQL.

Configure Nagios Environment within NagiosQL

After the Installation Wizard succeeded, you should configure your Nagios Environment for NagiosQL. Please login to your fresh installation and navigate to "Administration" => "Domains". Setup your Nagios Environment and if you need help, try the integrated help system first.
