    how to connect tomcat to apache - 503 on the website via ajp

    I am getting 503 on my website. I am trying to connect tomcat with apache. I tried several things. I cant seem to make it work.

    I have enabled a2enmod
    a2enmod proxy_ajp
    a2enmod proxy
    a2enmod proxy_http
    a2enmod ssl

    first error I was getting...
    proxy:ajp 'client denied by server configuration'
    I was getting forbidden on the browser, I played with apache settings, and checked...

    grep -r 'Connector port="8009"' *

    Then, I have added address="127.0.0.1" on tomcat6 server.xml
    <Connector port="8009" address="127.0.0.1" protocol="AJP/1.3" redirectPort="8443"/>
    cd /var/log/apache2 cat error.log

    now, I am getting this error...
    [Tue Feb 26 12:46:47 2013] [error] ap_proxy_connect_backend disabling worker for (localhost)
    [Tue Feb 26 12:46:47 2013] [error] proxy: AJP: failed to make connection to backend: localhost

    [Tue Feb 26 12:52:15 2013] [error] proxy: AJP: failed to make connection to backend: localhost
    ps ax | grep httpd | wc -l
    1
    please advise

    Thank you.
