nagios webinterace - site not found

[chr1s]

Hey,

i installed nagios 4.1.1 on a vmserver ubuntu 16 without without any Errors.
i followed this guide http://www.ubuntugeek.com/install-nagio ... erver.html and everything was fine.
but when i try to check out the webinterface http://localhost/nagios i`m able to log on but then i get the site not found error - http 404

i restarted nagios and apache2 Service and both are up and running.
Any Ideas?

thanks,
chris

Please run the following from the command line. While it is running reproduce the 404 error and after you see it, copy the output and post it here.
tail -f /var/log/apache2/error.log

Also, referencing the install guide you used, did you "Run the following command instead of make install-webconf" (see the section "Compile and install Nagios Using the following commands")

sudo /usr/bin/install -c -m 644 sample-config/httpd.conf /etc/apache2/sites-enabled/nagios.conf

- thanks -

I ran the command and uploaded the error.log.

After i got the error message´:
/usr/bin/install -c -m 644 sample-config/httpd.conf /etc/httpd/conf.d/nagios.conf
/usr/bin/install: cannot create regular file ‘/etc/httpd/conf.d/nagios.conf': No such file or directory
Makefile:296: recipe for target ‘install-webconf' failed
make: *** [install-webconf] Error 1

thats why i used : sudo /usr/bin/install -c -m 644 sample-config/httpd.conf /etc/apache2/sites-enabled/nagios.conf without any error Messages.

thanks

Can you refresh the page that is erroring out a few times, and then post your entire error_log? It doesn't look like anything in that screenshot is applicable as to what's going on with apache not being able to load the Core file.

[lmiltchev]

In addition to this, can you run the following commands and show the output?

Code: Select all

apache2 -v
php -v
mysql -V
systemctl is-enabled nagios
cat /etc/init.d/nagios
ps -ef | grep 'nagios\|apache2'

[chr1s]

grep nagios Output:
nagios@nagios:~$ ps -ef | grep `nagios/|apache2`
-bash: nagios/: Datei oder Verzeichnis nicht gefunden

attached the "cat nagios" output

Did everything compile properly? Was selinux enabled during the install?

Can you also run the following 4 commands?

Code: Select all

apache2 -v
php -v
mysql -V
systemctl is-enabled nagios

Your installation does not look proper at all. To be honest, it might make more sense to start fresh. @lmiltchev labbed this out and it is working following the exact guide you mentioned.

[chr1s]

I made the Installation again and now it works so far - but now i have another permission issue

when i try to access the Website and switch to "hosts" or "Services" i receive : You don't have permission to access /nagios/cgi-bin/status.cgi on this server.

permission on /usr/local/nagios/bin -rwxrwxr-x 1 nagios nagcmd

thanks for helping me out

[rkennedy]

Can you post your cgi.cfg file? Also, are you using the user 'nagiosadmin', or have you added a custom one?
