nginx - php-fpm - vbseo

I'm opening this post in hope to get some info on this setup from real world usage, not examples, since i can not find a lot of info about vbulletin with this setup, not to mention the vbseo addition.

After lots of digging some headache and a dead site i got my site working again on a different server with php-fpm and nginx

Firt, after an almost unresponsive server and being puzzled a few hours, php-5.3 does not seem to play nice (too much server load) after downgrading to 5.2 apache and nginx behaved nicely...
and then i had to move away the sql server because it went crazy/slow

My runing config is:

nginx.conf:

Code:

user www-data;
worker_processes  1;
worker_rlimit_nofile 8192;




error_log  /var/log/nginx/error.log notice;
pid        /var/run/nginx.pid;

events {
    worker_connections  2048;
    use epoll;
}

http {
    server_tokens off;
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    access_log  /var/log/nginx/access.log;
#    error_log   /var/log/nginx/error.log notice;
    
    sendfile        on;
    tcp_nopush     on;
    tcp_nodelay        on;

#    keepalive_timeout  0;
    keepalive_timeout  20	15;
    keepalive_requests	200;

    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;
}

my nginx (only/default) vhost:

Code:

server {
	listen       112.123.123.234:80;
    server_name  somesite.com;
        rewrite ^(.*) http://www.somesite.com$1 permanent;
    }
    
    
    
server {
	listen       123.123.123.234:80 default;
        root   /var/www/nginx/default/htdocs/;

        gzip                            on;
        gzip_min_length                 1100;
        gzip_buffers                    8 16k;
        gzip_comp_level                 1;
        gzip_types                      text/plain text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript;
        gzip_disable                    "MSIE [1-6]\.";

        output_buffers                  1 32k;
        postpone_output                 1460;

}

my server is now a P3 with 1Gb RAM, load is near 2.5 in average, memory, 900 of 1Gb used, 60Mb swapped.

on a normal day i can go to 300 users online (200 right now)

page generation time is between 1 and 2 secs :S, im also using APC

/nginx-status:

Code:

Active connections: 57 
server accepts handled requests

Reading: 3 Writing: 2 Waiting: 52

How do you see it? what wold you change, and why?


i got interested on the try_files option i saw in other post, however i did not fully understand if this causes a bug with moving posts, which for now seems like i dont have it.

i also had to disable attachments rewrite and im having lots of 404's!!! (any fix?)

Basically that server will not be able to hold 300 online users. You need to upgrade your server.

Thanks Mert, thats confusing, i tough i could run this on a VPS with 512 ram, and since the CPU is being shared with other VPSs...
i think im really wrong on what i knew about this hardware needs then, what would you use for this?

about the nginx setup, anyone has any toughs?

mm i made a mistake the server is P4 2.8Ghz with 1Ghz RAM, SATA hdd

Server with P4 will not run a "good" forum, If your daily forum posts increased so sure your visitors will increase and this server can't hold a high visitors number + more new posts, I would say this server will be better for a personal sites not forums.

Thanks Marco,
@all: what hardware would you recomend for my site, based on your experience ?

It all depends on your stats but if you constantly have 300 online users you will need a powerfull server.
