Apache fcgi deployment: 404 errors

I have an application that I'm trying to deploy on apache with fcgi. Assuming my application is called 'myapp' I'm trying to set it up so I can get to it at a url like http://myapp.mydomain.com/myapp.wt

My apache virtual host is set up as follows:

<VirtualHost *:80>
             ServerName myapp.mydomain.com
             DocumentRoot /var/www/myapp
             <Directory /var/www/myapp>
                        AllowOverride all
                        Allow from all
                        options ExecCGI
             </Directory>
</VirtualHost>

I moved the wt resources directory to /var/www-resources/wt/.

The resource for my application including the css and img directories were moved to /var/www-resources/myapp/

Next I changed/added the following relevant lines in my wt_config.xml.

<server>
    <application-settings location="*">
        .
        .
        .
        <property name="resourcesURL">/var/www-resources/wt/resources/</property>
        .
        .
        .
    </application-settings> 

    <application-settings location="/var/www/myapp/myapp.wt">
        <properties>
            <property name="favicon">/var/www-resources/myapp/img/favicon.ico</property>
            <property name="appRoot">/var/www-resources/myapp/</property>
        </properties>
    </application-settings>
</server>

I thought that this would be everything I needed to do to set this up but when I go to the URL I get a login page but with no styles or images. The following 404 errors are in my apache log:

Hey,

I guess it's because you specified the "file system path" of the wt resources folder for the "resourcesURL" property.

A URL is relative to the DocumentRoot (which you've configured as "/var/www/myapp"

You should thus make sure that you move the resources inside your DocumentRoot, e.g. /var/www/myapp/wt/resources/, and you only need to specify the location relative to "/var/www/myapp", e.g. "/wt/resources/".

Thanks Koen.

I moved everything where it should be and it works. I didn't realize that everything is relative to the document root specified in the apache virtual host.

Now, however, the app works but I'm getting new errors. If I leave the browser for a while, when I come back to the page it tells me there is a 500 error. I refreshed the page and the error log gives me the following:

Any ideas on what causes this would be appreciated.

Hey,

This doesn't look too bad --- I suspect that the refresh worked as expected too ?

The reason for the 500, we should be able to infer from the log files preceding the refresh ?

RE: Apache fcgi deployment: 404 errors - Added by Sean Lynch over 13 years ago

I think it has something to do with how I update the internal path. When I hit refresh it brings me back to the main page, but the url listed is still listed as the page that I was on when I hit refresh. Then I use the functionality on the main page (add an entry and hit submit) and I get the 500 error. The shows the following:

update "user" set "version" = $1, "num_entries" = $2, "last_entry" = $3 where "id" = $4 and "version" = $5

Also, if I then manually type in the url for the main page http://myapp.mydomain.com/myapp.wt/myapp

I get the error in the browser

Error occurred.
