Deploying Advanced Template to AWS Elastic Beanstalk

Yii 2.0 General Discussions
1

I’m trying to launch my Yii2-advanced project on AWS’ Elastic Beanstalk stack running an nginx server. I have been unable figure out a configuration that allows me to access the backend of the site. I have tried extending the nginx configuration via the AWS documentation:

https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/platforms-linux-extend.html

Which does not work. So I modify the configuration manually via vim from the command line.

While using combinations of the following configuration settings:

To no avail. I have tried alias and root for the backend folder and each variation I get either a 404 (file not found) or 502 (bad gateway) error.

At bare minimum, this is what I’ve tried to add to my nginx configuration:

root /var/www/html/frontend/web;

index index.php index.html index.htm;

location /backend/ {
    root ../../backend/web;
}

What am I doing wrong?

Trento insert backend root as Absolute URL

root /var/www/html/backend/web;

3

Just tried this… Getting a 404 (file not found) error. What else do you suggest I look at or try?

Been at this for 2 days now :frowning:

4

But /frontend Is working?

Is there index.php file inside backend/web folder?

5

Yes, and I just tried adding the following line to the configuration under the backend settings and still no avail.

index index.php index.html index.htm;
6

Error 404 should be simple to catch.

I’ll also try to check nginx log and eventually make nginx in debug mode to check what path nginx is processing (because index.php is not found).

You gave me some stuff to look at! Thanks! I’m hoping this information will lead to a solution. Here are the complete lines I’ve added to my configuration.

location ^~ /backend {
    rewrite ^/backend(.*)$ /backend/web$1 last;
}

location ^~ /backend/web {
    root /var/www/html/backend/web;

    try_files $uri $uri/ /backend/web/index.php$is_args$args;
    location ~ /\.(ht|svn|git) {
        deny all;
    }

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_pass 127.0.0.1:9000;
    }
}

location / {
    try_files $uri $uri/ /index.php$is_args$args;
}

But this is what I found in the error log

*1 rewrite or internal redirection cycle while processing “/backend/web/web/web/web/web/web/web/web/web/web/web/”,

*2 rewrite or internal redirection cycle while processing “/backend/web/web/web/web/web/web/web/web/web/web/web/”,

*3 rewrite or internal redirection cycle while processing “/backend/web/web/web/web/web/web/web/web/web/web/web/web/index.php”

So it seems to be that server is a rewrite loop. clearly something is wrong with my configuration. Any advice?

Thanks for getting me this far!

I don’t understand why backend config should be different from frontend.

9

What are you referring to exactly? What should I change?

Made some changes and now getting bad gateway error.

10

I am not having any luck here. I have even opened a question on stack overflow

Has no one successfully launched the advanced template on Nginx recently?

I’m currently using PHP 8 and Nginx 1.20.00.

You can see in the stack overflow questions the different configurations I’ve tried. Someone has to know the fix to this.

@samdark Would you be able to help at all?

11

I have no experience with AWS Beanstalk.

12

@samdark

I understanding but do you have any guidance on how to configure nginx for the advanced template or can tag someone who does? (The yii2 docs recommendation does not work and the links up above do not work)

13

Recommendation in docs is for multiple domains. That’s the whole goal of advanced application. But if you want to serve from a single domain:

14

Thanks but I actually posted this exact same link in my original post up above. As stated, the configuration does not work. I have tried it and many variations of it to no avail.

I have tried other configurations that people have claimed work for the advanced template to no avail.

I have literally copied and pasted these configurations and not changed a single character… Still, they do not work.

I’m beginning to suspect there is a quirk somewhere, perhaps in the latest yii2 release or Nginx that is preventing these configurations from working.

I have been unable to find a recent configuration from the past 12 months.

I am hoping that someone more advanced and capable than I is willing to try these configurations with the latest release of yii2 and see if they can get it to work themselves on Nginx.

I am truly at a loss here.

If I stumble across a solution or figure it out, I will make a new guide, but right now, there doesn’t seem to be a way to do this.

Hi @QuantumPsi,

The wiki shows 2 options:

  • The Easy Way
  • The Hard Way

Which one did you try? It looks to me that the easy way is quite straightforward and very easy to implement. Did you try the hard way?

16

Yes, I’ve tried both and even combined both methods.

I’ve copied and pasted the code and still no luck.

If you give me some time, I’ll post every configuration I’ve tried and their results.

17

Yeah, I want to see it.

First off, how did you configure the nginx and what error did you get when you tried “the easy way”?

18

Alright, I’ll post the other configurations I’ve tried later (traveling at the moment), but here’s what happened when I used the methods outlined here…

Method 1:
Created a link to the backend and restarted the server. The URL is replaced as expected to domain.com/backend/web/site/login, however, what is displayed is a 404 error, page not found. There are no errors in the error log.

And here is the COMPLETE nginx configuration, including the amazon specific files. For the record, I removed the amazon specific files thinking they may have had something to do with the issue, but removing them made no difference.

These are the config lines in the frontend
frontend\config\main.php

        'request' => [
            'baseUrl' => '',
        ],
        'urlManager' => [
            'enablePrettyUrl' => true,
            'showScriptName' => false,
            'enableStrictParsing' => false,
            'scriptUrl' => '/index.php',
            'rules' => [
            ],
        ],

And here is the backend
backend\config\main.php

        'request' => [
            'baseUrl' => '/backend',
        ],
        'urlManager' => [
            'enablePrettyUrl' => true,
            'showScriptName' => false,
            'scriptUrl' => '/backend/index.php',
            'rules' => [
            ],
        ],

Using these configuration settings, when going to the backend, I get a 502 error.

I’m going to submit this, my battery is low, so I want to get it submitted. I’ll add other comments if I think of anything later.

And this is what’s in the error log when trying to access the backend:

2021/09/05 15:54:10 [error] 19892#19892: *1 connect() failed (111: Connection refused) while connecting to upstream, client: 172.58.168.21, server: , request: "GET /backend/ HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "(servername).elasticbeanstalk.com"

“domain.com/backend/web/site/login” ? It’s not the expected URL of the backend login page. It should be “domain.com/backend/site/login”.

This command creates a symbolic link to “backend/web” directory as the name of “backend” in “frontend/web” directory. So, “/var/www/html/frontend/web/backend” is actually “/var/www/html/backend/web”. And because “/var/www/html/frontend/web” is the web root directory, “domain.com/backend” is located in “/var/www/html/frontend/web/backend”, i.e., “/var/www/html/backend/web”.

I guess the chances are that 1st option worked for you in fact but you misunderstood the expected URL of the backend.
