The Nginx configuration used by APISIX is generated via the template file apisix/cli/ngx_tpl.lua and the parameters in apisix/cli/config.lua and conf/config.yaml.
You can take a look at the generated Nginx configuration in conf/nginx.conf after running ./bin/apisix start.
If you want to customize the Nginx configuration, please read through the nginx_config in conf/config.default.example. You can override the default value in the conf/config.yaml. For instance, you can inject some snippets in the conf/nginx.conf via configuring the xxx_snippet entries:
... # put this in config.yaml: nginx_config: main_configuration_snippet: | daemon on; http_configuration_snippet: | server { listen 45651; server_name _; access_log off; location /ysec_status { req_status_show; allow 127.0.0.1; deny all; } } chunked_transfer_encoding on; http_server_configuration_snippet: | set $my "var"; http_admin_configuration_snippet: | log_format admin "$request_time $pipe"; http_end_configuration_snippet: | server_names_hash_bucket_size 128; stream_configuration_snippet: | tcp_nodelay off; ...
Pay attention to the indent of nginx_config and sub indent of the sub entries, the incorrect indent may cause ./bin/apisix start to fail to generate Nginx configuration in conf/nginx.conf.
