web page shows me timeout gateway error FastCGI

  • 772

I proceed to explain the problem and scenario a bit complex for my limited knowledge.

initially I thought it was some problem associated with the performance of my scripts and queries, so I created this post on the site in Spanish: LINK

but after researching most of the afternoon; I'm about to attribute it all to a misconfiguration of my dev environments.

I am working with 2 devices server:

  1. Local:

    • Windows 10
    • Laragon Server

  2. Development:

    • Ubuntu 20.04
    • XAMPP

in this case I will focus on local:
I have configured the laragon stack to support virtual hosts and run 2 versions of PHP (7.2 / 7.4) i have follow this 2 guides: Link 1 AND Link 2

my apache configuration:

Define SRVROOT "C:/laragon/bin/apache/httpd-2.4.47-win64-VS16"

ServerRoot "C:/laragon/bin/apache/httpd-2.4.47-win64-VS16"

I definitely accept that the mysql query is relatively large for a local environment on Windows; but the problem is that the same query is executed by apache handler 2.0 and php 7.4 in less than 1 second ... but in CGI / FastCGI it stops when it reaches the timeout (180 seconds / 3 minutes) ... I have had the delicacy of set the same settings for FastCGI and Apache Handler 2.0 but not concive because one fails and the other does not.

Of course, of course, that's why one of my doubts is that they tell me in my setup what configuration I need to improve FastCGI. It is what I mainly ignore. (where, how and what).

it is possible that someone tell me in my setup what configuration I need to improve FastCGI. It is what I mainly ignore. (where, how and what) I really don't understand why I can't make Fast CGI at least not break and work like Apache does ...

I do not know what is wrong, what I need or how to solve these errors ... I know that CGI / FastCGI is taking a long time and consuming a lot of memory but I don't know why it not work and Apache Handler Work correctly

Or exist any way to proxy Apache Handler 2.0 instead of use php-cgi via FastCGI alias?

UPDATE #1

i find this configuration file: Note: I am assuming that this configuration file is important; but I have no idea of its functionality or what things should I add, remove or modify to make FastCGI behave like Apache Handler 2.0.

    The errors tells you its PHP (Version 7.2, EoL now, fix that!) that is trying to exceed its allocated memory limit.

    If the script was terminated while talking to the database (the mysql logs makes me think so), then maybe one of your database queries (not necessarily the last one!) is returning an unexpectedly large result set that does not fit the memory allowed for the php script?

    Check query log, execute the queries manually and see

    • if are appropriate: then you want to allocate more resources OR:
    • if one of them is unnecessarily large: then you want to improve the application querying them or cleanup unnecessary rows to reduce resource usage.

    If it is the former, then keep in mind most systems are setup to have separate php configurations for separate deployment options. This may include different memory limits or available extensions. As you have multiple different deployments, the used php.ini file may be different for each of cgi, cli, fpm, apache2-mod, .. - if in doubt, let your script print phpinfo() to confirm the effective configuration.
