Directory redirection issue with nginx set as reverse proxy

Asked 2022-Mar-26 at 12:05

I have configured the server through Reverse Foloxy as follows:

Nginx reverse proxy(SSL Termination) - Varnish cache - Nginx web server(8080 port)

However, it has the following problems: For example, if you go to https://www.example.com/static (this is an example only, your domain is not my site), you will be redirected to http://www.example.com:8080/static/ . It is the same when accessing not only staic but also other directories. I am wondering how to do something like nginx.conf etc to solve this problem.

You can use varnishlog to debug as described in https://www.varnish-software.com/developers/tutorials/troubleshooting-varnish/#backend-errors.

Just run sudo varnishlog -g request -q "VCL_call eq 'BACKEND_ERROR'" and paste the content here. I'll help you debug.

You are only hitting the log record limit vsl_reclen

Use varnishadm param.set vsl_reclen X to increase it at runtime or the -p vsl_reclen=X command line argument to varnishd.

If you need to go to particularly high values, consider to increase vsl_buffer also. If you do that, also increase workspace_client and workspace_backend by the same amount.

Unable to load compiled assets (CSS) after installation of Varnish & hitch

It's loading fine when i stop Varnish.

Also tried to bypassed site but issue still exists:

...

ANSWER

Answered 2022-Feb-16 at 18:06

One of the reasons why the CSS might not be loading is because of mixed content. Please check whether or not your static assets are loaded over HTTP whereas the page is loaded via HTTPS.

If that is the case, you need to make sure your application is aware of the terminated protocol. Registering the X-Forwarded-Proto header is one way of achieving this.

Use the PROXY protocol

As described in https://www.varnish-software.com/developers/tutorials/terminate-tls-varnish-hitch/#retrieve-tls-information-with-vmod_proxy, if the communication between Hitch and Varnish happens over the PROXY v2 protocol, you can use vmod_proxy to extract TLS information and set the X-Forwarded-Proto header.

This would be the VCL code:

Change cache control directive for stale responses in Varnish

Asked 2022-Feb-14 at 13:46

This is my first time experimenting with Varnish.

We noticed our CDN not doing any request coalescing, so as an experiment I'm allowed to try out Varnish.

However I can't seem to figure out how to modify the response headers when stale content is served.

Image the following vcl and all backend responses have max-age=60, public, s-maxage=600 as the cache-control directive.

Varnish 503 Backend Fetch failed

Asked 2022-Jan-07 at 13:34

I have a server running Ubuntu 20.04, nginx and varnish with letsencrypt SSL.

I have installed PHPMyAdmin to the default server block and have another server block for my actual website running magento 2.4.3. This was all working fine until i installed varnish and now when trying to load either site i get the 503 Backend fetch failed error and when i try and load then on port 8080 from the URL i get a "this page cannot be reach" error.

I have configured nginx to listen on port 8080 for both sites, i have set varnish to listen on port 80. I have edited the vcl generated by magento to set the host and port to 127.0.0.1 and 8080 respectively as shown on https://devdocs.magento.com/guides/v2.4/config-guide/varnish/config-varnish-configure.html.

ANSWER

Answered 2021-Dec-31 at 09:20

From the $_SERVER documentation:

The entries in this array are created by the web server.

When running PHP on the command line, there is no web server involved, that means no $_SERVER['DOCUMENT_ROOT'].

If your scripts must run the same with the CLI SAPI and a web server SAPI, don't rely on such variables. To include other PHP scripts, use the __DIR__ magic constant instead:
