Hello Folks,

is it possible to use NGINX AIO on CentOS5, or is the CentOS5 Kernel too  
old for this?

Greetings

2.6.18-164.el5 but redhat does a lot of backporting. i tried to compile  
it on a centos 5 machine with ./configure --with-file-aio and get this

checking for Linux AIO support … not found

./configure: no supported file AIO was found  
Currently file AIO is supported on FreeBSD 4.3+ and Linux 2.6.22+ only

seems like centos 5 & redhat enterprise 5 are too old

but i have the following packages installed, regarding to aio

libaio-devel-0.3.106-3.2  
libaio-0.3.106-3.2  
libaio-0.3.106-3.2  
libaio-devel-0.3.106-3.2

nginx does not use libaio. nginx requires eventfd() AIO support.  
I tested AIO on CentOS 5.2.

Strange, i tried to compile it with ./configure --with-file-aio but the  
error message is the same. did you use the original centos kernel or a  
self baked one?

if its the original kernel in you case, are you sure that aio was  
active?

Sorry, I was wrong. I had two VirtualBox installations: Debian and  
CentOS 5.2,  
both have 2.6.18 kernel. Specially for AIO I had installed openSUSE 11.1  
with more modern kernel.

Игорь, у меня CentOS 5.6 ядро 2.6.18-274.3.1.el5PAE  
конфигурирую с --with-file-aio  
выходит  
checking for Linux AIO support … found

а вы писали что поддержка AIO идет только  
2,6,22 и выше!?

</div>

и еще 1 вопрос.  
у меня 16Гб оперативки конфиг такой:  
user nginx;  
worker\_processes 8;  
worker\_rlimit\_nofile 819200;  
timer\_resolution 100ms;  
worker\_priority -5;

http {  
#aio  
aio on;  
expires max;  
#directio 1m;  
sendfile off;  
tcp\_nopush on;  
tcp\_nodelay on;  
server\_tokens off;  
gzip off;  
gzip\_static on;  
gzip\_comp\_level 5;  
gzip\_min\_length 1024;  
keepalive\_timeout 65;  
output\_buffers 2 512k;

раздаю с сервера видео ролики и мелкие  
тумбочки. Ролики размером от 5 до 200  
мегабайт.

какой параметр directio и output\_buffers мне  
указать лутше?  
Спасибо.

Игорь мы это уже обсуждали в другой  
теме. у меня ffmpeg конвертирует с h264.  
без nginx\_mod\_h264\_streaming-2.2.7 и с mp4\_module Я не могу  
мотать ролики. ☹

Спасибо за ответ.  
с конфигом что вы дали, видео ролики  
вообще не грузятся, плеер сбрасывает. В  
ошибках вижу это:

2011/10/13 16:55:12 [crit] 23226#0: \*145115 aio read  
“/var/www/html/pub2/video/102011/8/85/634/885634152246.mp4” failed (22:  
Invalid argument) while sending mp4 to client, client: 217.25.22.82,  
server: [server.com](http://server.com), request: “GET  
/pub2/video/102011/8/85/634/885634152246.mp4 HTTP/1.1”, host:  
“[server.com](http://server.com)”

Мне приходится выключать directio, и после  
ролики подгружаются, но без directio в AIO  
толку нет.

Спасибо за патч, после этого AIO  
заработало, но файлы с h264 не  
показываются на swf плеере пока не  
подкачиваются до конца. Пришлось  
вернуться на --add-module=/gus/nginx\_mod\_h264\_streaming-2.2.7  
и за комментировать #directio=1m;

На самом деле проблема с AIO воспроизводится и сегодня, но только при  
использовании некоторых плееров. К большому сожалению при использовании  
плеера Uppod.

У меня указано это в локейшине:

    location / {

        index index.html index.htm index.php;
            location ~ \.mp4$ {

```

при компиляции с --with-http\_mp4\_module видео не  
проигрывается пока не подкачается до  
конца, а если передвигаю ползунок  
плеера, например на 30 сек после старта,  
подкачиват видео, но без звука.

приходится снова ставить с  
–add-module=/gus/nginx\_mod\_h264\_streaming-2.2.7.
