I am new to this product and just wanting to get familiarized with it. I have installed "Nagios-4.3.2 core on Centos 7. I have gone through the install document. The issue I am having is in the document after the install is complete and the httpd & nagios service is started its says you should be able to go to the following site http://nagiosip/nagios/. When trying to go there I don't get much. I have verifed that the service are running see below.

[root@nag nagios-4.3.2]# ps -ef |grep httpd
root 32322 1 0 12:07 ? 00:00:00 /usr/sbin/httpd -DFOREGROUND

apache 32740 32322 0 12:12 ? 00:00:00 /usr/sbin/httpd -DFOREGROUND

[root@nag nagios-4.3.2]# ps -ef |grep nagios
nagios 32374 1 0 12:07 ? 00:00:00 /usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg
nagios 32376 32374 0 12:07 ? 00:00:00 /usr/local/nagios/bin/nagios --worker /usr/local/nagios/var/rw/nagios.qh
nagios 32377 32374 0 12:07 ? 00:00:00 /usr/local/nagios/bin/nagios --worker /usr/local/nagios/var/rw/nagios.qh
nagios 32378 32374 0 12:07 ? 00:00:00 /usr/local/nagios/bin/nagios --worker /usr/local/nagios/var/rw/nagios.qh
nagios 32379 32374 0 12:07 ? 00:00:00 /usr/local/nagios/bin/nagios --worker /usr/local/nagios/var/rw/nagios.qh
nagios 32380 32374 0 12:07 ? 00:00:00 /usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg

Please if someone could advise what I may be missing or doing wrong. I suspect when I got to this site http://nagiosip/nagios/ I should see some login prompt.

Thanks

Hi,
how do You install Your Nagios - from source or from repository??

1. Does http://nagiosip/ return apache welcome page ??

2. Please verify /usr/local/nagios/share directory and check for nagios webgui files (php,html,cgi)

3. Verify Your nagios httpd config file

Code: Select all

ScriptAlias /nagios/cgi-bin "/usr/local/nagios/cgi"
<Directory "/usr/local/nagios/cgi">
#       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
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>

Another log file you can view to see why the Nagios GUI is not opening up is the /var/log/httpd/error_log file.

Without knowing which instructions you used and is there were any errors, it will be difficult to help but the first thing to try is to reinstall Nagios using the instructions in this KB article.
