Hi There,

I am pretty new to all this hosting stuff but I like a challenge :) So far I managed to install and configure Ubuntu LAMP with name based virtual hosts and host a couple of websites. Very happy with results!

I was playing around with longview but noticed I couldn't get data from Apache, all the other tabs worked:


Quote:
Unable to access local server status for Apache at http://127.0.0.1/server-status?auto: 404 Not Found


Apache status module has been enabled
Then I had to edit status.config: sudo nano /etc/apache2/mods-available/status.conf

Code:
<IfModule mod_status.c>
ExtendedStatus On
<Location /server-status>
    SetHandler server-status
    Order deny,allow
    Deny from all
    Allow from 127.0.01
#  Allow from .example.com
</Location>
</IfModule>

After that I made sure this file had to right code: /etc/linode/longview.d/Apache.conf

Quote:
location <http://127.0.0.1/server-status?auto>


Still same error. Am I doing something wrong here? Probably missing something obvious ;) Hope someone can help me out here.

Thanks

Did you restart Apache after making the configuration changes? The 404 error means that Apache doesn't know what to return when /server-status is requested.

Also, the Allow from line needs to say 127.0.0.1, not 127.0.01 - this would cause a 403 Forbidden error.

Sorry for not responding, I was on a (well deserved holiday). The 127.0.01 was a typo in my post. In status.config it's 127.0.0.1. I did restart apache.

Weirdest thing: I just got home and checked longview. Every single tab gives me a connection error right now. I think the only thing I did change before I went away was change the firewall settings. I used this document and I just double checked but I entered everything as stated (also the longview exception):

https://www.linode.com/docs/security/se ... a-firewall

Wondering why I am getting these connection errors all of a sudden :-/

The errors are gone now it says Waiting... :?

Log gives indication why but I can't figure out where I went wrong.

Code:

I had a similar problem when setting up a new Ubuntu 14.04 LTS Linode recently. I can't remember what I had to add to the status.conf file to get Longview to monitor Apache, but here's my status.conf file in full:

Code:
<IfModule mod_status.c>
   # Allow server status reports generated by mod_status,
   # with the URL of http://servername/server-status
   # Uncomment and change the "192.0.2.0/24" to allow access from other hosts.
   ExtendedStatus On
   Listen 127.0.0.1:8081
   <Location /server-status>
      SetHandler server-status
      Require local
      Require ip 127.0.0.1
   </Location>

   # Determine if mod_status displays the first 63 characters of a request or
   # the last 63, assuming the request itself is greater than 63 chars.
   # Default: Off
   #SeeRequestTail On

   <IfModule mod_proxy.c>
      # Show Proxy LoadBalancer status in mod_status
      ProxyStatus On
   </IfModule>

</IfModule>


It may've been the 'Listen 127.0.0.1:8081' line that needed to be added. Bear in mind that Ubuntu 14.04 LTS comes with Apache 2.4, which uses different syntax for deny/allow etc, although I believe the old syntax from 2.2 will still work.

According to this, you're running nginx, not Apache.
