WordPress MU

This is better for a basic set up which does not include supercache :

server {
listen       80;
server_name muinstall.com *.muinstall.com;

access_log  /usr/local/nginx/logs/mu.access.log;

location ~* ^.+\.(xml|jpg|jpeg|gif|png|ico|css|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js|swf)$
	{
		root /home/mudirectory/public_html;
		rewrite ^/files(/.*)$ /wp-content/blogs.php?file=$1 last;
		expires 10d;
		break;
	}

location / {
            	root   /home/mudirectory/public_html;
            	index index.php;
	    	error_page       404 = /index.php?q=$uri;
}

location ~ \.php$ {
	fastcgi_pass   127.0.0.1:9000;
	fastcgi_index  index.php;
	fastcgi_param  SCRIPT_FILENAME /home/mastersvn/mutrunk$fastcgi_script_name;
	include        /usr/local/nginx/conf/fastcgi_params;
}

}

Thanks. Interestingly I got the wildcard working without the *. that you added at the top. I will try your version today adn report back. Much obliged.

It will work without the wildcard if your mu installation is also the default nginx server conf.

Yup this works.

server
{

	listen			80;
	server_name		MYSITE.COM	*.MYSITE.COM;

	access_log 		/home/public_html/MYSITE.COM/log/access.log;
	error_log 		/home/public_html/MYSITE.COM/log/error.log;

# rewrite rule for files

	location	~*	^.+\.(xml|jpg|jpeg|gif|png|ico|css|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js|swf)$
	{
		root		/home/public_html/MYSITE.COM/www;
		rewrite		^/files(/.*)$	/wp-content/blogs.php?file=$1	last;
		expires		10d;
		break;
	}

# rewrite rule for sitemap under the lines that handles upload files

	rewrite ^(.*/)?sitemap.xml wp-content/sitemap.php;

# rewrite errors

	location	/
	{
		root		/home/public_html/MYSITE.COM/www;
		index		index.php;
		error_page	404	= /index.php?q=$uri;
	}

#send php requests to fast cgi

	location	~	\.php$
	{
		fastcgi_pass		127.0.0.1:9000;
		fastcgi_index		index.php;
		fastcgi_param		SCRIPT_FILENAME		/home/public_html/MYSITE.COM/www$fastcgi_script_name;
		include				/usr/local/nginx/conf/fastcgi_params;
	}

}

Now to figure out supercache!

Just a FYI. I had to change error_page 404 = /index.php?q=$uri; to get it to work with BuddyPress. I changed it to:

if (!-e $request_filename) {
    rewrite ^(.+)$ /index.php?q=$1 last;
}
