nginx 오류

【1】 nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
[::]:80 is a ipv6 address.
This error can be caused if you have a nginx configuration that is listening on port 80 and also on port [::]:80.
I had the following in my default sites-available file:
listen 80; listen [::]:80 default_server; You can fix this by adding ipv6only=on to the [::]:80 like this:
listen 80; listen [::]:80 ipv6only=on default_server; For more information, see:

4.2. Authorization
The “Authorization” header field allows a user agent to authenticate itself with an origin server – usually, but not necessarily, after receiving a 401 (Unauthorized) response. Its value consists of credentials containing the authentication information of the user agent for the realm of the resource being requested.

 Authorization = credentials

If a request is authenticated and a realm specified, the same credentials are presumed to be valid for all other requests within this realm (assuming that the authentication scheme itself does not require otherwise, such as credentials that vary according to a challenge value or using synchronized clocks).
A proxy forwarding a request MUST NOT modify any Authorization fields in that request. See Section 3.2 of [RFC7234] for details of and requirements pertaining to handling of the Authorization field by HTTP caches.
