I notice that one of my WordPress sites is configured with the below and when upgrading from nginx 1.23.4 to 1.25.3 this line was not changed to the new separated directives:

Code (Text):

listen 443 ssl http2 reuseport;

All of my sites sit behind CloudFlare so I'm not sure why only this one has the reuseport parameter. My server kernel supports SO_REUSEPORT sockets.

Are there other reasons for using reuseport and what is the ideal nginx 1.25.3 listen directive configuration considering I'm using CloudFlare on all my sites?

Many thx in advance.

 

Understood, thanks.

Do you know if there's an equivalent config for nginx 1.25.1+ to avoid the warning?

Code (Text):

nginx: [warn] the "listen ... http2" directive is deprecated, use the "http2" directive instead

I assume it will be quite a while until they actually remove the http2 parameter though.

 

Yeah I read that earlier.

Could I configure the vhost in question as follows rather than leave as is with the warning:

Code (Text):

listen 443 ssl reuseport;
http2 on;

 

That's the point of the thread.

I did upgrade using Centmin Mod 130.00beta01 and the process auto converted all of my nginx vhosts apart from the one which has the reuseport parameter. It left that one as is, I assume because it has the reuseport parameter.

 

Cheers!

Apologies if I wasn't more explicit earlier, I had two queries in one.

Can I ask if reuseport applies to only the vhost it is set or does it apply and improve all vhosts on the server?
