So_reuseport

Hello,
Ihave rebuild nginx 1.9.1 from source to use SO_REUSEPORT on my wheezy
install with kernel 3.16 (from backports).
(packages from http://nginx.org/packages/mainline/debian/has not include
SO_REUSEPORT)

Some errors are still present:

[emerg] 19351#19351: duplicate listen options for 0.0.0.0:80 in …

Is there a way to use “reuseports” for multiple locations?
How can I test if it works for a special location?
Is there a header send or something else? Or is the only way to compare
“stress test” like siege?

Regards,
Basti

Try the latest 1.9.2, in 191 is was added but not working.

You have to declare it once and only once.

Please read:

http part is fully functional in 1.9.1. The author has different
issue and Lukas T. already answered.

This is not true.

Much like all other listening socket options, “reuseport” have to
be specified only once, usually in a default server for a listen
socket in question. That is, if you have many servers listening
on port 80, you should write something like:

server {
    listen 80 reuseport;
    server_name default.example.com;
    ...
}

server {
    listen 80; # no options here
    server_name virtual.example.com;
    ...
}

To check if reuseport actually works just check how many listening
sockets were created - normally there will be just one,
but with reuseport you’ll see multiple listening sockets, one for
each of nginx worker processes. Something like “ss -nlt” should
show listening sockets on Linux.

I stand corrected, mistakenly took
http://hg.nginx.org/nginx/rev/f654addf0eea for a http issue.
