Description
I use nginx provided by atomic repos in centos 6.5
First I set up the following variable in the server block.
set $fastcgi_cache_zone one;
BTW I tried to define a global/default one in the http block but I get this error:
[emerg] "set" directive is not allowed here in /etc/nginx/nginx.conf
Then I write this in the php location block which is inside the server block
fastcgi_cache $fastcgi_cache_zone;
And this also fails in the purge location block which is inside the server block. However this is using the module ngx_cache_purge-2.1 which I don't know if it is supported here.
fastcgi_cache_purge $fastcgi_cache_zone "$scheme$request_method$host$1";
The error is this one for both:
nginx: [emerg] "fastcgi_cache" zone "$fastcgi_cache_zone" is unknown in /etc/nginx/nginx.conf:53

The fastcgi_cache directive doesn't support variables. If variables can be used in a certain directive arguments, that's explicitly documented. See, e.g., fastcgi_param documentation - "The value can contain text, variables, and their combination."
The set directive can't be used in http context. Note "context" in the documentation.
The fastcgi_pass directive support variables (though it's implies special processing, and may require resolver to be defined, see http://nginx.org/r/proxy_pass; the fastcgi_pass documentation needs to be updated to include these details). If it doesn't work for you - you are probably doing something wrong, consider writing to the mailing list if you need help.
Also trying to pass a variable as an argument for fastcgi_pass doesn't work. It doesn't give any errors when executing "nginx -t" but from the logs I can tell it can't read the variables as nginx thinks it is empty:
