    # Load config files from the /etc/nginx/conf.d directory 
        
    include /etc/nginx/conf.d/*.conf; 

    }  
    This is the configuration.
    But it seems there is some problem on this.

    ip.address/some.html -- always throws 404 error
    ip.address/some.php -- works good. But it seems both server are handling this request and the loading is very slow.

    What have i done wrongly?
    I used http://www.howtoforge.com/reduce-apache-load-with-nginx-rhel5.2
    using centos 6 64 bit.

    Installed in the following way
    yum install nginx || yum install httpd

    Thanks for the reply.
    How do i know the reverse proxy is working correctly?

    This is what i have found after making some changes.

    Apache Access log : Contains request for php only.
    Nginx Access log : Contains request for php and images, css, javascript.

    I think nginx is not configured to run php.
    I did yum install nginx.

    Is reverse proxy working correctly then?

    yum install phpmyadmin.

    *** PHPMYADMIN is working, but unable to upload sql files. Icons in phpmyadmin is not working.

    Thanks for helping me.

    I have disabled php_cli module in apache.
    <?php echo phpinfo(); ?> said, apache is running both php_cli and php_fcgid
    So i disabled php_cli is that correct?

    Thanks
