Error 404 HTTP not found

Postby devilsguest » Mon Apr 01, 2013 9:29 am

I have installed apache 2.2.24 on my linux box and have both my nagios service, Apache service up and running. But I don't see any communication between them. My page directly kicks back me to error 404 when typed the url http://localhost or ip/nagios. Conf file has no issues.....can some one help me out. Please look into the attached how the url looks like....

Are you browsing to port 77 or do you have a redirect to port 77 from port 80? (i.e. http://nagios_server_ip:77)
If so, then your problem, unfortunately, most likely lies in your apache config.

It seems like port 80 is not open. You should see:

Code: Select all
PORT   STATE SERVICE
80/tcp open  http

I am using port 77 to browse there are no redirect ports. I have changed the port number.Here, I am not using default port. Probably, I don't think changing port number would make a difference while browsing.

Here I have a question.....why is apache trying to extract nagios webconf file from its htdocs file? I think I found the issue but don't really know where to change the path for apache to communicate with nagios to display the home page.

Just curious - is SELinux enabled on this box? If it is, can you try disabling it and see if this is going to help?

Code: Select all
setenforce 0

Post the output of the following:
Where is your config and how was it parsed?
Code: Select all
httpd -S

Where is your "ServerRoot"?
Code: Select all
cat /path/to/httpd.conf | grep ServerRoot

Have you declared:
Code: Select all
Listen 77

in your httpd.conf?
Code: Select all
cat /path/to/httpd.conf | grep Listen

    # access content that does not live under the DocumentRoot.
    # Example:
    # Alias /webpath /full/filesystem/path
    #
    # If you include a trailing / on /webpath then the server will
    # require it to be present in the URL.  You will also likely
    # need to provide a <Directory> section to allow access to
    # the filesystem path.

    #
    # ScriptAlias: This controls which directories contain server scripts.
    # ScriptAliases are essentially the same as Aliases, except that
    # documents in the target directory are treated as applications and
    # run by the server when requested rather than as documents sent to the
    # client.  The same rules about trailing "/" apply to ScriptAlias
    # directives as to Alias.
