Probably another web interface 404 thread :)

[datguy.dev]

Greetings,
I so was looking for a network monitoring platform to run on a Raspberry Pi (Raspbian). A friend of mine recommended Nagios, so I thought I'd try out the core+plugins. The issue is I get "curl: (6) Couldn't resolve host 'http:192.168.1.169,'" 404 unreachable on other machines or browser, when trying to reach the web interface. I've come to a point where I'm trying random solutions. So I thought I'd ask here first instead of digging the hole even deeper; so to speak.

Initially, I read threw and followed the instructions here: https://assets.nagios.com/downloads/nag ... Source.pdf The installation went fine until "make install-webconf." I did not have any web applications installed like apache to save space on 4GB SD card.

I followed these instruction as a remedy:
1-sudo mkdir /etc/httpd
2-sudo mkdir /etc/httpd/conf.d
3-sudo mkdir /etc/httpd/conf.d/nagios.conf
Along with sudo apt-get install build-essential libgd2-xpm-dev apache2-utils

After doing these suggestions, install-webconf passed without error. Everything was smooth sailing from these. I simply completed the install, added the plugins, then manually started the nagios service. Then this is when I the the web interface wall. Experience wise, I'm not that new to linux but I still have a lot to learn. If you would help me figure this out I would greatly appreciate your efforts. <3

Hopefully this information will be of some use?

To clarify - you will need httpd running.

I believe the command you're looking to run is -

Code: Select all

http:://192.168.1.169

Additionally, this should be a file, and not a directory -

3-sudo mkdir /etc/httpd/conf.d/nagios.conf

Here's the contents of my nagios.conf -

Code: Select all

# SAMPLE CONFIG SNIPPETS FOR APACHE WEB SERVER
#
# This file contains examples of entries that need
# to be incorporated into your Apache web server
# configuration file.  Customize the paths, etc. as
# needed to fit your system.

<Directory "/usr/local/nagios/sbin">
#  SSLRequireSSL
   Options ExecCGI
   AllowOverride None
   <IfVersion >= 2.3>
      <RequireAll>
         Require all granted
#        Require host 127.0.0.1

         AuthName "Nagios Access"
         AuthType Basic

      Order allow,deny
      Allow from all
#     Order deny,allow

      AuthName "Nagios Access"
      AuthType Basic
      AuthUserFile /usr/local/nagios/etc/htpasswd.users
      Require valid-user

</Directory>

<Directory "/usr/local/nagios/share">
#  SSLRequireSSL
   Options None

   <IfVersion >= 2.3>
      <RequireAll>
         Require all granted

         AuthName "Nagios Access"
         AuthType Basic
         AuthUserFile /usr/local/nagios/etc/htpasswd.users
         Require valid-user
      </RequireAll>
   </IfVersion>
   <IfVersion < 2.3>
      Order allow,deny
      Allow from all
#     Order deny,allow
#     Deny from all
#     Allow from 127.0.0.1

      AuthName "Nagios Access"
      AuthType Basic
      AuthUserFile /usr/local/nagios/etc/htpasswd.users
      Require valid-user
   </IfVersion>
</Directory>

What is the output of these commands?

Code: Select all

service httpd status
service nagios status

Sorry, please close this thread.

While awaiting moderation I stumbled upon a solution. I had to add the red text here: http://nagios.manubulon.com/traduction/ ... llweb.html to apche2.conf. But after experiencing the process of registering hosts, I decided not to use Nagios in the end.

Sounds good - looks like the apache configuration didn't generate.

Feel free to open a new thread if you need any assistance in the future.
