Hello support,
Here’s what I did:
- follow your tutorial http://rtcamp.com/easyengine/ setup fresh wordpress on ec2 amazon
- Increase php limit http://rtcamp.com/tutorials/php/increase-script-execution-time/
- Install w3 totalcache and memcache
- replace the code for /etc/nginx/sites-available/example.com (details code below)
- restart nginx [nginx -t && service nginx reload] => I got 502 bad gateway; restart nginx or my ec2, but no hope; replace my old code (without w3cache config) it work again.
What did I do wrong? please help
server {
server_name newgirl.vn http://www.newgirl.vn;
access_log /var/log/nginx/newgirl.vn.access.log rt_cache;
error_log /var/log/nginx/newgirl.vn.error.log;

set $cache_uri $request_uri;
POST requests and urls with a query string should always go to PHP
if ($request_method = POST) {
set $cache_uri ‘null cache’;
}
if ($query_string != “”) {
set $cache_uri ‘null cache’;
}
Don’t cache uris containing the following segments
if ($request_uri ~* “(/wp-admin/|/xmlrpc.php|/wp-(app|cron|login|register|mail).php|wp-.*.php|/feed/|index.php|wp-comments-popup.php|wp-links-opml.php|wp-locations.php|sitemap(index)?.xml|[a-z0-9-]±sitemap([0-9]+)?.xml)”) {
set $cache_uri ‘null cache’;
}
Don’t use the cache for logged in users or recent commenters
if ($http_cookie ~* “comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_logged_in”) {
set $cache_uri ‘null cache’;
}
Use cached or actual file if they exists, otherwise pass request to WordPress
location / {
try_files /wp-content/cache/page_enhanced/${host}${cache_uri}_index.html $uri $uri/ /index.php?$args ;
}
location ~ ^/wp-content/cache/minify/[^/]+/(.*)$ {
try_files $uri /wp-content/plugins/w3-total-cache/pub/minify.php?file=$1;
}
location = /favicon.ico { log_not_found off; access_log off; }
location = /robots.txt { log_not_found off; access_log off; }
location ~ .php$ {
try_files $uri /index.php;
include fastcgi_params;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_read_timeout 600;
}
Cache static files for as long as possible
location ~* .(ogg|ogv|svg|svgz|eot|otf|woff|mp4|ttf|css|rss|atom|js|jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|tar|mid|midi|wav|bmp|rtf)$ {
expires max; log_not_found off; access_log off;
}
}
Many thanks,
