不同的文档有不同的解决方案。
http://wiki.nginx.org/WordPress 的方案有这么几点：
首先要加map指令
<a href="http://wiki.nginx.org/NginxHttpMapModule#map">map</a> $http_host $blogid {
default -999;
#Ref: http://wordpress.org/extend/plugins/nginx-helper/
#include /var/www/wordpress/wp-content/plugins/nginx-helper/map.conf ;
}
这个的作用是手工定义了网站名$http_host和网站id$blogid之间的对应关系。比如
We use Nginx’s map {..} section to hold site-names and site-ids pairs as you can see in following example:
<code>map $http_host $blogid {
default 0;
example.com 1;
site1.example.com 2;
site1.com 2;
}</code>
Using it, Nginx can map a request for file:
<code>http://site1.com/files/2012/09/somefile.png</code>
to file-system path:
<code>/var/www/example.com/htdocs/wp-content/blogs.dir/2/2012/09/somefile.png </code>
这个里面 site1.com 就和 2 对应了。有了这个手工对应就不需要再进行数据库查询。换句话说，这个指令不用multisite也可以正常运作。
然后就是server{}里面的配置。
<a href="http://wiki.nginx.org/NginxHttpCoreModule#server_name">server_name</a> example.com *.example.com ; <a href="http://wiki.nginx.org/NginxHttpCoreModule#root">root</a> /var/www/example.com/htdocs; <a href="http://wiki.nginx.org/NginxHttpCoreModule#index">index</a> <a href="http://wiki.nginx.org/NginxHttpCoreModule#index">index</a>.php;
这些是基本配置了，没什么特别。
<a href="http://wiki.nginx.org/NginxHttpCoreModule#location">location</a> / {
<a href="http://wiki.nginx.org/NginxHttpCoreModule#try_files">try_files</a> $uri $uri/ /<a href="http://wiki.nginx.org/NginxHttpCoreModule#index">index</a>.php?$args ;
}
这个指令将$uri内部转向到 /<a href="http://wiki.nginx.org/NginxHttpCoreModule#index">index</a>.php?$args
<a href="http://wiki.nginx.org/NginxHttpCoreModule#location">location</a> ~ \.php$ {
<a href="http://wiki.nginx.org/NginxHttpCoreModule#try_files">try_files</a> $uri =404;
<a href="http://wiki.nginx.org/NginxHttpCoreModule#include">include</a> fastcgi_params;
<a href="http://wiki.nginx.org/NginxHttpFcgiModule#fastcgi_pass">fastcgi_pass</a> php;
}
#WPMU Files
<a href="http://wiki.nginx.org/NginxHttpCoreModule#location">location</a> ~ ^/files/(.*)$ {
<a href="http://wiki.nginx.org/NginxHttpCoreModule#try_files">try_files</a> /wp-content/blogs.dir/$blogid/$uri /wp-includes/ms-files.php?file=$1 ;
<a href="http://wiki.nginx.org/NginxHttpLogModule#access_log">access_log</a> off; <a href="http://wiki.nginx.org/NginxHttpCoreModule#log_not_found">log_not_found</a> off; <a href="http://wiki.nginx.org/NginxHttpHeadersModule#expires">expires</a> max;
}
#WPMU x-sendfile to avoid php readfile()
<a href="http://wiki.nginx.org/NginxHttpCoreModule#location">location</a> ^~ /blogs.dir {
<a href="http://wiki.nginx.org/NginxHttpCoreModule#internal">internal</a>;
<a href="http://wiki.nginx.org/NginxHttpCoreModule#alias">alias</a> /var/www/example.com/htdocs/wp-content/blogs.dir;
<a href="http://wiki.nginx.org/NginxHttpLogModule#access_log">access_log</a> off; <a href="http://wiki.nginx.org/NginxHttpCoreModule#log_not_found">log_not_found</a> off; <a href="http://wiki.nginx.org/NginxHttpHeadersModule#expires">expires</a> max;
