Nagios Installation - URL not found

[silverspirit]

Hi,
I recently installed Nagios Core on a SuSe Linux system incl. Apache.

The Apache testpage is visible when connecting from a remote site to /<server_name>/
Accessing Nagios is not possible using /<server_name>/nagios (The requested URL /nagios was not found on this server.)

I assume if the apache test webpage is visible there is no firewall restriction at all, so the nagios page should be visible ? (the server is using not the standard firewall, so I first would need to take a look at the manuals for this specific firewall)

The apache log is saying:
160.50.3.130 - - [12/Oct/2012:15:43:07 +0200] "GET /nagios HTTP/1.1" 404 204

The nagios log shows:
[1350045462] SERVICE ALERT: localhost;HTTP;CRITICAL;SOFT;2;Connection refused
[1350045522] SERVICE ALERT: localhost;HTTP;CRITICAL;SOFT;3;Connection refused

Thanks

Have you cracked open your Apache server's access logs? I believe for suse they are located here:

Code: Select all

/var/log/httpd.access_log

[silverspirit]

No, actually its about a SLES server, the access_log is located here
/usr/local/apache2/logs

[slansing]

Oh sorry I must need more coffee, have you taken a look at the access_log? can you post it here?

[silverspirit]

find attached the complete apache2 access log file.
the connectivity tests were done at around 12/Oct/2012:14:29:08
I am also not sure what the other regular messages mean (error 200 45)

Thanks

Did you add an apache conf that points to the nagios directory?

[silverspirit]

In the meantime I figured out, the 404 error was caused by a missing Alias in httpd.conf
Now I am getting 403 errors I'll try to fix.
I am wondering why this isn't part of the installation procedure...

[silverspirit]

I am getting confused again, still struggeling with 403 (permission denied) error, not sure what to do next, hopefully someone can point me to the right direction.

I have added the following lines to apache config file httpd.conf:

Code: Select all

#document root alias
Alias /nagios /usr/local/nagios/share

<Directory /usr/local/nagios>
  Order allow,deny
  Allow from all
</Directory>

In the directory section I have tried both /usr/local/nagios/share (folder where eg index.php is located) and also /usr/local/nagios

In the logs I can see the following:
error_log

Code: Select all

[Mon Oct 15 16:43:04.981158 2012] [authz_core:error] [pid 14647:tid 140009560459024] [client 160.50.3.130:1459] AH0

Code: Select all

160.50.3.130 - - [15/Oct/2012:16:43:12 +0200] "GET /nagios HTTP/1.1" 403 208

Further for testing I have disabled (uncommented) the restrictions in the main Directory setting:

Code: Select all

<Directory />
#    AllowOverride none
#    Require all denied
</Directory>

and now I was able to get at least the left frame of the page, but it wasn't shown properly. I also used the URL //<server_hostname>/nagios/index.php

Code: Select all

160.50.3.130 - - [15/Oct/2012:16:50:58 +0200] "GET /nagios HTTP/1.1" 301 233

I am also wondering why I didn't got the nagios login popup window yet

Any help is appreaciated.

I hate to ask, but is PHP installed on this system?

Your nagios.conf file should look something like this (this is from a source install):

Code: Select all

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 Core"
   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 Core"
   AuthType Basic
   AuthUserFile /usr/local/nagios/etc/htpasswd.users
   Require valid-user
</Directory>

mh, PHP is not installed currently. I tried to install it before without success, later I was reading the Nagios openSUSE core Quickinstall guide where php was not included as required package. (in difference to the fedore guide) This seems to be wrong. 3 steps back
