If you are using the WP Super Cache plugin by Automattic, this configuration can help you settings up your Nginx caching proxy:
[code]proxy_cache_path /data/nginx/cache keys_zone=one:10m inactive=24h max_size=1G;
proxy_cache_key “$host$request_uri$cookie_user”;
proxy_cache one;
server {
server_name ~^(static\.)?(?
access_log /var/log/nginx/domains/static.$domain.log;
location ~ ^/(wp-content|wp-includes)/ {
resolver 8.8.8.8;
expires 30d;
add_header Pragma public;
add_header Cache-Control “public”;
proxy_cache_valid 200 10m;
proxy_pass http://www.$domain;
add_header X-Cache-Status $upstream_cache_status;
}
}[/code]
Change the static.domain.com to the hostname the nginx server is listening to. Change domain.com (twice!) to the main domain where the content is pulled from.
Make a DNS record (either cname or a) pointing static.domain.com to the IP the nginx server is running at.
Be sure to chmod the /data/nginx/cache folder to 700 and change the ownership to the same user as nginx is running (default nginx).
Check if the cache is working by using this command:
[code]du -h –max-depth=1 /data/nginx/cache[/code]
Easy as that!
