    Hi all,

    I want to thank everyone for their hard work getting these walk-throughs set up for those of us who aren't linux demigods (yet). However there seems to be a problem with Timme's how-to, The Perfect Server - CentOS 6.4 x86_64 (nginx, Dovecot, ISPConfig 3).

    I've gone through each and every step, carefully, and multiple times (I like to repeat an install a few times using VMs to get the feel for what I'm actually doing and observe the behaviors I am modifying). I finally come to the end checking off every step and get a 502 error trying to connect to ISPConfig on http(s)://192.168.10.10:8080 and http(s)://servername.domain.local:8080 (internal domain, not an internet machine).

    All services appear to running perfectly fine, I've seen no startup errors. I followed the guide to a T, checking and rechecking, and still nothing. IPTables is disabled, SELinux is disabled. This leaves me unable to configure any of the sites (phpmyadmin, mailman, squirrelmail, etc) leaving the server essentially worthless.

    If anyone has any insight into why this is happening I'd really appreciate the help. It doesn't make much sense to me. I have done the same configuration guide using Apache instead of Nginx and that one worked fine, however I'd like to start getting familiar with Nginx.

    As an aside, I really think the site configuration explanations can be done better on this guide. Why put all of the info for configuring each site in ISPConfig under the install process for the application instead of after the installation of ISPConfig? Logically, we're going to be setting that config data after ISPConfig is installed, so hiding it under previous subheaders doesn't create a clear and direct guide and manages to somewhat muddle the instructions by putting invaluable information out of sequence (and subsequently confusing new learners). Just a consideration.

    What are the outputs of
    Code:
    netstat -tap
    and
    Code:
     iptables -L
    ?

    Did you disable SELinux?

    Do you get any errors when you restart nginx?

    Nginx starts up just fine. It seems a little weird to me.

    Have you tried to restart PHP-FPM?
