Unknown directive "thread_pool"

Server NGINX
1

Hi
First time trying aio threads on linux, and I am getting this error

[emerg] 19909#0: unknown directive “thread_pool” in
/usr/local/nginx/conf/nginx.conf:7

Line7 reads:
thread_pool testpool threads=64 max_queue=65536;

Everything indicates it was built --with-threads, so I’m not sure where
to go from here

nginx -V:
/usr/local/nginx/sbin/nginx -V
nginx version: nginx/1.9.1 built by gcc 4.8.2 (Ubuntu 4.8.2-19ubuntu1)
configure arguments: --with-debug --with-file-aio --with-threads

from configure output:
Configuration summary

  • using threads

Any help appreciated
Thanks
Richard

Hi Richard,

Do you have an Ubuntu package for Nginx installed also (usually
installed in /usr/sbin)? Depending on how you are starting it the wrong
executable may be being used.

Kind Regards
Andrew

Thanks Andrew
I figured this out but it was not a duplicate binary
It was because I was issuing -HUP to reload nginx rather than proper
start/stop :-[

Cheers
Richard

Ah! That was my next guess. I’m glad you sorted it. If you have this
problem again there is a way to do a rolling upgrade without a
start/stop, see this link for more info:

Kind Regards
Andrew

Добрый день.
Не понятно мне, куда помещать настройку по пулам.

uname -orm

FreeBSD 10.1-RELEASE-p12 amd64
nginx -v
nginx version: nginx/1.8.0
nginx собран с оцией --with-threads
Далее.
nginx.conf в секцию http добавил:
thread_pool one threads=32;
thread_pool cen threads=32;
После делаю проверку.

nginx -t

nginx: [emerg] “thread_pool” directive is not allowed here in
/usr/local/etc/nginx/nginx.conf:46
nginx: configuration file /usr/local/etc/nginx/nginx.conf test failed
Как в инструкиях сказано, что в секцию http добавляется настройка по
пулам,
а после проверки конфига мне говорится, что опции theread_pool тут не
место.
Как быть в этом случае.
Хочу реализовать отдачу картинок на обном из нагруженных проектов.
И есть ли смысл использовать пулы от nginx на системе FreeBSD 10.1 ?

I am not sure you need threads with freebsd because it has native aio
support.

То-есть, на системе FreeBSD смысла нет использовать пул потоков от
nginx?
Про пул от nginx мало информации и примерров.

Just add ‘aio on;’ instead of ‘aio threads;’.
Also you should compile nginx without threads.

У меня aio работает, оно помоему по умолчанию до 1,9 ветки.
Я прописывал в локейшены свои aio threads; но это стандартно, хотелось
для
каждого проекта сделать свой пул.

“unknown directive” != “directive is not allowed here”

nginx.conf:

Hi Francis,

There is a complete and simple configuration in the “Configuring

Also, there is a russian version of this article on habrahabr.ru.

You should use native AIO on FreeBSD instead.

Это я все понимаю.

Пока отложу настройку пулов, пусть используются родные фряхины.

I hope I didn’t end up answering the wrong question.

Thanks for the pointer; I’ve had a read through it. It looks
generally good – but it does show the thread_pool directive
at http level: possibly either that or the documentation at
Core functionality should be
updated to be consistent?

I think the original poster has the answers wanted – thread_pool goes
outside http, and probably isn’t needed on FreeBSD for file reads –
so it all looks good.

Cheers,

Good catch. It should be fixed. Thanks.
