Yii2.0高级模板前后台共用一个域名的配置

以www.ff.com为例，访问后台的路径则为www.ff.com/admin

server {
    listen       80;   
    server_name  www.ff.com;

    set $root /home/wwwroot/ff;
    root $root;
    index       index.php;

    access_log   /home/wwwroot/ff/logs/access.log;
    error_log    /home/wwwroot/ff/logs/error.log;

    location / {
        root /home/wwwroot/ff/frontend/web;
        try_files $uri /frontend/web/index.php?$args;
        location ~ \.(js|css|png|jpg|gif|swf|ico|pdf|mov|fla|zip|rar)$ {
            access_log  off;
            expires  360d;
            try_files  $uri =404;
           }
         }

         location /admin {
            alias  /home/wwwroot/ff/backend/web;
            rewrite  ^(/admin)/$ $1 permanent;
            try_files  $uri /backend/web/index.php?$args;
         }
         location ~ ^/admin/(.+\.(js|css|png|jpg|gif|swf|ico|pdf|mov|fla|zip|rar))$ {
            access_log  off;
            expires  360d;
            rewrite  ^/admin/(.+)$ /backend/web/$1 break;
            rewrite  ^/admin/(.+)/(.+)$ /backend/web/$1/$2 break;
            try_files  $uri =404;
         }

         location ~ \.php$ {
            #fastcgi_pass   127.0.0.1:9000;
            fastcgi_pass  unix:/tmp/php-cgi.sock;
            fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include        fastcgi_params;
            try_files  $uri =404;
         }

         location ~ /\.ht {
            deny  all;
         }
    }
