问题
I'm trying to make a docker environment for a Prestashop project. I have it almost working but for some reason, the back office is inaccessible - it gives me a ERR_TOO_MANY_REDIRECTS error.
I changed the urls in shop_url table and changed PS_SHOP_DOMAIN and PS_SHOP_DOMAIN_SSL to no vain. I tried to disable friendly URLs, enable/disable SSL - but the problem persists.
I'm using a custom image for a webserver:
luken-wodby-nginx-prestashop Dockerfile:

ENV WODBY_DIR_FILES /mnt/files
RUN rm /etc/gotpl/default-vhost.conf.tpl && \

COPY prestashop.conf.tpl /etc/gotpl/

}
Website works just fine, only the back office is inaccessible and gives ERR_TOO_MANY_REDIRECTS error.
Any ideas what can be wrong?
回答1:
I found the cause of the problem. The wodby/nginx nginx container is using a custom fastcgi_params file. This file strangely enough doesn't have fastcgi_param QUERY_STRING $query_string; line (in contrast to the original file that comes with nginx). This makes it incompatible by default with some ready nginx templates that you can find on the internet. It manifests itself by query parameters not getting passed to the script (I created an issue for it here: https://github.com/wodby/nginx/issues/3 ).
Now, Prestashop's back office not having an important controller parameter freaks out, because it doesn't know which controller to run. If there is no controller, it does a redirection to the URL with a default controller as a parameter, but because there is never a "controller" parameter available for Prestashop, it ends in redirection loop causing ERR_TOO_MANY_REDIRECTS.
The fix for this is to add fastcgi_param QUERY_STRING $query_string; in your nginx configuration to pass query parameters to the script.

As far as I remember, on installation, Prestashop needs to be with full folder permissions, whereas it causes thoses kind of problems.
So for instance :
chmod 777 -R /var/www/html
should do the job
