php4nagios doesn't work on fresh install

[davide.bonicelli]

hi, i've just tried to install php4nagios on a new nagios installation on a centos 7 x64.
i followed the official guide
https://support.nagios.com/kb/article/n ... nd_Config)
but i stuck at the check of the page http://nagios_server/pnp4nagios/ that resolv in a not found page (of course i changed nagios_server with the correct ip)
any idea on this?
i don't see nothing in logs...

Go to the /var/log/httpd folder and look at the error_log file or if you enabled SSL the ssl_error_log file while you are trying to access the pnp4nagios link.
If you find any errors, post them here.

Can you get the Apache config file for PNP4Nagios and post it here?

Code: Select all

/etc/httpd/conf.d/pnp4nagios.conf

Thanks

The config file looks stock but thanks for posting it.

Here is a couple of things to look for.
When you access the pnp4nagios URL, it is accessing the following folder.
Check it to see if the permissions are set so the nagios user and and the nagcmd group can read it.

Code: Select all

/usr/local/pnp4nagios/share

When you go to the GUI, does it prompt for a username and password?
If not, check the /usr/local/nagios/etc/htpasswd.users file to see if there is an account created in it.

Also, there are some steps you can do to troubleshoot this on the PNP4Nagios web site.

Thanks Tom, the permissions look good for me..

Code: Select all

ls -la /usr/local/pnp4nagios/share
totale 20
drwxr-xr-x  8 nagios nagios  155 21 dic 11.22 .
drwxr-xr-x  9 root   root     89 21 dic 11.06 ..
drwxr-xr-x 12 nagios nagios  144 21 dic 11.06 application
drwxr-xr-x  6 nagios nagios   60 21 dic 11.06 documents
-rw-r--r--  1 nagios nagios 4785 21 dic 11.22 index.php
-rw-r--r--  1 nagios nagios 7310 21 dic 11.22 install.php
drwxr-xr-x  5 nagios nagios   41 21 dic 11.06 media

drwxr-xr-x  2 nagios nagios  100 21 dic 11.22 templates.special

No user and pw asked when i go to the gui homepage..only 404
in htpasswd i see only nagiosadmin..is it correct?

in the link you send me i didn't found anything useful for my problem..

If you did not add any other users to the htpasswd file, then the nagiosadmin user should be in there.

Lets try and reinstall pnp4nagios but specify the user and group in the configure command.
Go to the folder that you downloaded pnp4nagios and run the following commands as root to reinstall it.

Code: Select all

./configure --with-nagios-user=nagios --with-nagios-group=nagios
make all
make install
make install-webconf
make install-config
make install-init
service httpd restart

Then see if you can login.


If it fails, try stopping the firewall of the system if it is enabled.

Try running the install script to see if that opens in the browser.

Code: Select all

http://nagios_server/pnp4nagios/install.php

Other than that, there has to be more information in the Apache Error logs on why it is not running.

Thanks Tom, as usually you solved my problem : )
the

Code: Select all

configure --with-nagios-user=nagios --with-nagios-group=nagios

did the trick

Your Welcome. Glad it worked.
