Nginx Reverse proxy proxy_cache_path directive is not allowed error resolution _nginx

The following error occurred during an attempt to reverse proxy using Nginx:

Copy Code code as follows:

Nginx: [Emerg] "proxy_cache_path" directive is isn't allowed here in/etc/nginx/conf.d/default.conf:29

Hint meaning "Proxy_cache_path instruction is not allowed", found the relevant instructions on the official web site, also did not find the problem, finally see the application range only know, he can only be used for http{} part, put Proxy_cache_path in the HTTP section can solve this problem
