New Nagios Core user

[Joel]

I installed the free 60 day trial version of Nagiosxi and got that to work on VMware Player. Now I'm trying to install Nagios Core on my Windows 7 laptop. I am trying to test out this monitoring system for my office. I just need some help installing Core on my computer. I'm not sure if I need to install a Linux server on VMware player, and then install Core on the virtual server. Please give me a step by step process of how to get started. Please let me know what versions I need to install as well.

Thanks.

You will need a RHEL/ CENTOS / Ubuntu vm to follow these steps:

I am working through my first install as well and I am setting Nagios up on an Ubuntu 14.04 LTS server with Apache2. If you are doing the same and following the directions that were previously posted you will need to do a mkdir /etc/httpd and mkdir /etc/httpd/conf.d before running the make install-webconf step. That last step puts the nagios.conf file in the conf.d directory. What I did was copy the following from the nagios.conf file and put it in the apache2.conf file:

ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"

<Directory "/usr/local/nagios/sbin">
# SSLRequireSSL
Options ExecCGI
AllowOverride None
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
</Directory>

Alias /nagios "/usr/local/nagios/share"

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

I did a "vi +150 /etc/apache2/apache2.conf" to get to the correct section. Good luck.

I tried to use Ubuntu and I could not get Core to work. Then I used CentOS and it took all the commands, but I still could not access Nagios through my browser.

Just to verify joel, when you installed, you did so from source and based on the documentation that slansing provided? What kind of output were you getting when attempting to access the webserver?

[Joel]

Oops! Google Chrome could not connect to 192.168.198.131

[sreinhardt]

OK, that could be all sorts of things. Let's start from the top.

Code: Select all

service iptables status
iptables -L
service httpd status

here are some screen shots of what you requested.

Wait... Why is this being done on a live CD? Nothing done on a live CD will persist after a reboot. You need to install the operating system first instead of running it off the CD. This also does not look like a typical CentOS terminal, it looks more like Ubuntu.

And just as an aside, is there a reason you wanted to test Core when you have an XI system working? Core can be pretty Linux-heavy, so if you aren't entirely comfortable at a command line you might find XI easier to maintain.

My boss wants to try the Opensource version, so I am trying to set it up.
