wordpress | 多站点模式下访问某一文件夹文件返回 404

这是 wordpress 的一个多站点问题。

介绍一下背景，假设域名为 xxx.com，现在新建了一个新的站点 xxx.com/lumi，现在这个站点的主题需要上传一个 SDK，假设这个 SDK 的文件夹名称为 Extend。

但是，在多站点的配置下，访问 xxx.com/lumi/Extend/a.js 返回 404。

我的 wordpress 是放置在 /var/www/wordpress 里面的。

所以，我将 Extend 上传到 /var/www/wordpress/Extend 或者 /var/www/wordpress/lumi/Extend 还是 404。

然后我修改 nginx 配置，添加

location /lumi/Extend {
	alias /var/www/wordpress/Extend;
}

也不行，经过我长期的排查，最后发现是 nginx 多站点配置问题。

nginx 多站配置为

• wordpress | wordpress 搭建(包含多站点)

# Upstream to abstract backend connection(s) for php
upstream php {
        server unix:/tmp/php-cgi.socket;
        # server 127.0.0.1:9000;
}

server {
        listen 80;
        ## Your website name goes here.
        server_name _;
        ## Your only path reference.
        root /var/www/wordpress; # wordpress 的放置路径
        ## This should be in your http block and if it is, it's not needed here.
        index index.php;

location = /favicon.ico {
                log_not_found off;
                access_log off;
        }

location = /robots.txt {
                allow all;
                log_not_found off;
                access_log off;
        }

location / {
                # This is cool because no php is touched for static content.
                # include the "?$args" part so non-default permalinks doesn't break when using query string
                try_files $uri $uri/ /index.php?$args;
        }

location ~ \.php$ {
                #NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
                include fastcgi_params;
                fastcgi_intercept_errors on;
                fastcgi_pass php;
                #The following parameter can be also included in fastcgi_params file
                fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
        }

location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
                expires max;
                log_not_found off;
        }

#ignored: “-” thing used or unknown variable in regex/rew
        rewrite ^/([_0-9a-zA-Z-]+/)?wp-admin$ /$1wp-admin/ permanent;

if (-f $request_filename){
            set $rule_2 1;
        }
        if (-d $request_filename){
            set $rule_2 1;
        }
        if ($rule_2 = "1"){
        #ignored: “-” thing used or unknown variable in regex/rew
        }
        rewrite ^/([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) /$2 last;
        rewrite ^/([_0-9a-zA-Z-]+/)?(.*.php)$ /$2 last;
        rewrite /. /index.php last;
}

最后发现，是最后一句话

rewrite /. /index.php last;

影响了。这句话是说，把所有的 url 都定向到 index.php

所以，我们要对这句话进行改造，还要加入

location /lumi/Extend {
	alias /var/www/wordpress/Extend;
}

}

        listen 80;

       server_name thlm.com www.thlm.com;
       listen 443 ssl default_server;

        rewrite ^/([_0-9a-zA-Z-]+/)?(.*.php)$ /$2 last;
       rewrite ^/(?!lumi/Extend)(.*)$ /index.php?$1 last;
}

完美解决。
