   I edit apisix config file like this: 
   ```
   nginx_config:                     # config for render the template to genarate nginx.conf
     error_log: "logs/error.log"
     error_log_level: "warn"         # warn,error
     worker_rlimit_nofile: 20480     # the number of files a worker process can open, should be larger than worker_connections
     event:
       worker_connections: 10620
     http:
       access_log: "logs/access.log"
       keepalive_timeout: 60s         # timeout during which a keep-alive client connection will stay open on the server side.
       client_header_timeout: 60s     # timeout for reading client request header, then 408 (Request Time-out) error is returned to the client
       client_body_timeout: 60s       # timeout for reading client request body, then 408 (Request Time-out) error is returned to the client
       send_timeout: 10s              # timeout for transmitting a response to the client.then the connection is closed
       underscores_in_headers: "on"   # default enables the use of underscores in client request header fields
       real_ip_header: "X-Real-IP"    # http://nginx.org/en/docs/http/ngx_http_realip_module.html#real_ip_header
       real_ip_from:                  # http://nginx.org/en/docs/http/ngx_http_realip_module.html#set_real_ip_from
         - 127.0.0.1
         - 'unix:'
       proxy_busy_buffers_size:   512k
       proxy_buffers:   4 512k
       proxy_buffer_size:   256k
   
       #lua_shared_dicts:              # add custom shared cache to nginx.conf
       #  ipc_shared_dict: 100m        # custom shared cache, format: `cache-key: cache-size`
   ````
   But dose not work.
