二级目录下的静态文件index.htm无法访问

nginx的一个conf片段：

location / {
       root   /usr/share/nginx/html/www.abc.com;
        index  index.php index.htm;
    if (!-f $request_filename){
        set $rule_1 1$rule_1;
    }
    if (!-d $request_filename){
        set $rule_1 2$rule_1;
    }
    if ($rule_1 = "21"){
        rewrite /. /index.php last;
    }

    }

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   html;
    }

    location ~ \.php$ {
        root   /usr/share/nginx/html/www.abc.com;
        fastcgi_pass   unix:/var/run/php-fpm.socket;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  /usr/share/nginx/html/www.abc.com$fastcgi_script_name;
        include        fastcgi_params;
    }
