Serving Images and attachments via nginx

June 01, 2010 06:07AM
Hi there I changed the way my servers act so I could reduce the load from my machines but would like some help with setting it up.

It would be really nice to let all users hit my main server (PHP), and then nginx can offload the images to one server and the attachments to another ???

here is my main config:

[code]
user www www;

worker_processes 8;

error_log /disk1/logs/nginx_main_error.log crit;

pid /usr/local/webserver/nginx/nginx.pid;

#Specifies the value for maximum file descriptors that can be opened by this process.
#worker_rlimit_nofile 51200;

events
{
use epoll;

worker_connections 1024;
}

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


## Size Limits
client_body_buffer_size 1k;
client_header_buffer_size 1k;
client_max_body_size 6m;
large_client_header_buffers 4 4k;
connection_pool_size 256;
request_pool_size 4k;
server_names_hash_bucket_size 128;


## Timeouts
client_body_timeout 60;
client_header_timeout 60;
keepalive_timeout 60;
send_timeout 60;


sendfile on;
tcp_nopush on;


tcp_nodelay on;

fastcgi_connect_timeout 60;
fastcgi_send_timeout 120;
fastcgi_read_timeout 45;
fastcgi_buffer_size 8k;
fastcgi_buffers 8 4k;
fastcgi_busy_buffers_size 8k;
fastcgi_temp_file_write_size 28k;
fastcgi_temp_path /dev/shm;

gzip on;
gzip_min_length 1100;
gzip_buffers 4 8k;
gzip_http_version 1.0;
gzip_comp_level 1;
gzip_proxied any;
gzip_types text/plain text/html text/css text/javascript text/xml application/x-javascript application/xml application/xml+rss;


server
{
listen 80;
server_name www.mysite.co.uk;
index index.html index.htm index.php;
root /data0/htdocs/www/forum;



location ~ .*\.php?$
{
include fcgi.conf;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;


}

error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /data0/htdocs/www/forum;
}


location ~* ^.+.(jpg|jpeg|gif|css|png|js|ico)$ {
access_log off;
expires 30d;
proxy_pass http://IP-ADDY-TO-IMAGE-SERVER;
}

log_format gzip '$remote_addr - $remote_user [$time_local] '
'"$request" $status $bytes_sent '
'"$http_referer" "$http_user_agent" "$gzip_ratio"';
access_log /disk1/logs/nginx-access.log gzip buffer=32k;
error_log /disk1/logs/nginx_error.log warn;


rewrite ^/((urllist|sitemap_).*\.(xml|txt)(\.gz)?)$ /vbseo_sitemap/vbseo_getsitemap.php?sitemap=$1 last;

# globally disable external access, but enable for X-Accel-Redirect
location /uploads {
internal;
}
# enable direct access to blogs & posts thumbnails, but nothing else!
location ~* /uploads/(.*)\.thumb$ {
}
# enable direct access to album thumbnails
location /uploads/thumbs/ {
}

if ($request_filename ~ "\.php$" ) {
rewrite ^/(.*)$ /vbseo.php break;
}

if (!-e $request_filename) {
rewrite ^/(.*)$ /vbseo.php break;

}


rewrite ^/archive/index.php/(.*)$ /archive/index.php?$1;




}
}

[/code]


I do not know how to make it work correctly for the images when I put the IP-ADDY-TO-IMAGE-SERVER it makes everything show up without images ?

Also what code would I use to point attachements like ZIP/RAR etc to another server? I was thinking this might work but again not sure?

[code]
location ~* ^.+.(rar|zip)$ {
access_log off;
expires 30d;
proxy_pass http://IP-ADDY-TO-ATTACHMENT-SERVER;
}
[/code]

and another thing should I use local network IP's or the Public ones in the proxy_pass directive?

Thank you very much for any help on this subject.

Mickie
