Nginx + Tomcat + Railo: Error to start

[Ivan]

Hello,

Today I run updates in Ubuntu 12.04. I have done a reboot of the server. But tomcat can no longer to boot.

These are the errors:

/opt/railo/railo_ctl restart

Hi Ivan,

From a quick Google search I found this forum post:

https://support.pivotal.io/hc/communities/public/questions/201699193-org-apache-catalina-LifecycleException-Failed-to-start-component

This bit seems relevant:

This is likely a JVM class loader issue. If you have multiple JAR files in the same directory with the same class in them (perhaps version A and version B of a library), there is no defined order in which the JAR files will be searched. On some platforms, A might get searched first, on others B might get searched first. Usually it's consistent for a platform, but it can technically change from run to run. The simple answer to this is don't leave old WAR files in the "lib" directory (or anywhere else on the class path). A way to troubleshoot this when it happens is to run your tc Server with the JVM options "-verbose". This will print the location from which the JVM loads a class file. You can then use that to find the offending libraries.

Hope that is helpful.

Kind regards,

Andrew

Hi Andrew,

OMG... Some days ago, I added a new host in server.xml but forgot to create the directory of the new site on the server ... On the first restart of tomcat froze everything ... I lost the whole day to understand it .... -_-

[Andrew Dixon]

Hi Ivan,

That's not good, but thanks for letting us know what it was as it is good to know Tomcat does that!!! Like Apache HTTPD you would think that would just generate a warning, not stop the whole thing from starting.

Kind regards,

Andrew

You could use mod_cfml with nginx and never have to edit your sever.xml file or restart tomcat again.

All that is needed on the nginx side is:

proxy_set_header    X-Tomcat-DocRoot    $document_root;

[Robert Munn]

I have not seen documentation on the mod_cfml site or on GitHub for using it with Nginx. Are there docs for using mod_cml with Nginx?

Nothing official. Anyone want to contribute to the project and create some docs on the subject? Please email me off list.

It is also very important to note the new security setting in the mod_cfml 1.1 valve, the 'Shared Key':
http://www.modcfml.org/index.cfm/documentation/modcfml-so-apache-module/config-options/

You can create the header manually by adding a header called: "X-ModCFML-SharedKey" to the request, similar to how you are manually creating the X-Tomcat-DocRoot header.

Example config/installer: https://groups.google.com/d/msg/lucee/xGkSHBeS8TA/awGoZqZYY8sJ

[Robert Munn]

So on the Nginx side, you need:

#add header for mod_cfml to do its work

proxy_set_header    X-Tomcat-DocRoot    $document_root;

Is there anything required on the Tomcat side? I see this host entry in server.xml:

      <Host name="lucee" appBase="webapps"

            unpackWARs="true" autoDeploy="true">

        <!-- SingleSignOn valve, share authentication between web applications

             Documentation at: /docs/config/valve.html -->

        <!--

        <Valve className="org.apache.catalina.authenticator.SingleSignOn" />

        -->

        <!-- Access log processes all example.

             Documentation at: /docs/config/valve.html

             Note: The pattern used is equivalent to using pattern="common" -->

        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"

               prefix="localhost_access_log." suffix=".txt"

               pattern="%h %l %u %t &quot;%r&quot; %s %b" />

        <!-- visit modcfml.org for details on mod_cfml configuration options -->

        <Valve className="mod_cfml.core"

                loggingEnabled="false"

                waitForContext="20"

                maxContexts="200"

                timeBetweenContexts="500"

                />

      </Host>

Seems like this valve needs to be added to an initial host in server.xml. Is that the case?

Just trying to clarify so any Nginx users who would like mod_cfml have some basic docs.

[Jonathan van Zuijlekom]

Yes, we just have one <host> in the server.xml with the mod_cfml valve. I just put the modcfml***.jar in the lucee directory.
