Nginx and Wordpress Super Cache

April 10, 2012 09:36PM
'm trying to setup a new server with nginx instead of LAMP using php-fpm. I've got wordpress setup and running, but I'm at a loss to figure out how to get Wordpress Super Cache working. I'd appreciate any help. I'm also trying to figure out how to get rid of the if statements in the wordpress Multisite configuration file. I do know about the ifisevil page.

I'd taken my initial configuration from: http://codex.wordpress.org/Nginx


My Sites-available file
---
# Redirect everything to the main site.
server {
listen 80 default;
server_name *.students.scisdragons.net;
rewrite ^ http://students.scisdragons.net$request_uri permanent;
}

server {
server_name students.scisdragons.net;
root /var/www/students.scisdragons.net;

include global/restrictions.conf;
include global/wordpress-ms-subdir.conf;
}


---


My global wordpress file
---

# WordPress multisite subdirectory rules.
# Designed to be included in any server {} block.

# This order might seem weird - this is attempted to match last if rules below fail.
# http://wiki.nginx.org/HttpCoreModule
location / {
try_files $uri $uri/ /index.php?$args;
}

# Add trailing slash to */wp-admin requests.
rewrite /wp-admin$ $scheme://$host$uri/ permanent;

# Directives to send expires headers and turn off 404 error logging.
location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
expires 48h;
log_not_found off;
}

# Pass uploaded files to wp-includes/ms-files.php.
rewrite /files/$ /index.php last;

# For multisite: Use a caching plugin/script that creates symlinks to the correct subdirectory structure to get some performance gains.
set $cachetest "$document_root/wp-content/cache/ms-filemap/${host}${uri}";
if ($uri ~ /$) {
set $cachetest "";
}
if (-f $cachetest) {
# Rewrites the URI and stops rewrite processing so it doesn't start over and attempt to pass it to the next rule.
rewrite ^ /wp-content/cache/ms-filemap/${host}${uri} break;
}

if ($uri !~ wp-content/plugins) {
rewrite /files/(.+)$ /wp-includes/ms-files.php?file=$1 last;
}

# Uncomment one of the lines below for the appropriate caching plugin (if used).
# include global/wordpress-ms-subdir-wp-super-cache.conf;
# include global/wordpress-ms-subdir-w3-total-cache.conf;

# Rewrite multisite '.../wp-.*' and '.../*.php'.
if (!-e $request_filename) {
rewrite ^/[_0-9a-zA-Z-]+(/wp-.*) $1 last;
rewrite ^/[_0-9a-zA-Z-]+(/.*\.php)$ $1 last;
}

# Pass all .php files onto a php-fpm/php-fcgi server.
location ~ \.php$ {
# Zero-day exploit defense.
# http://forum.nginx.org/read.php?2,88845,page=3
# Won't work properly (404 error) if the file is not stored on this server, which is entirely possible with php-fpm/php-fcgi.
# Comment the 'try_files' line out if you set up php-fpm/php-fcgi on another machine. And then cross your fingers that you won't get hacked.
try_files $uri =404;

fastcgi_split_path_info ^(.+\.php)(/.+)$;
include fastcgi_params;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
# fastcgi_intercept_errors on;
fastcgi_pass php;
