Description
This may very well be an incorrect expectation.
When SSL is configured but a file is missing NGINX errors.
If DHParams is configured but the target file is missing NGINX starts without any warnings or errors, including in the log.
Note:
See TracTickets
for help on using tickets.
Correctly reports an error here, with
ssl_dhparam /path/to/nowhere;in the configuration:$ nginx nginx: [emerg] BIO_new_file("/path/to/nowhere") failed (SSL: error:02001002:system library:fopen:No such file or directory:fopen('/path/to/nowhere','r') error:2006D080:BIO routines:BIO_new_file:no such file)Note though that there will no error if
ssl_dhparamconfigured is not used at all - for example, if you'll try to set it in aserver{}block without SSL configured.
