location中配置root，无效。

我在location中配置root，浏览器访问无效。搜了一天没找到答案，哪位大侠能告诉我为什么吗？

server {
    listen 80;
    server_name  localhost;
    #root  /usr/share/nginx/html/project/manage/public;   路径写在这里有效，写道location中无效，没搞懂！！！！


    location / {     
        root  /usr/share/nginx/html/project/manage/public;
        index  index.html index.htm index.php;
        if (!-e $request_filename) {
            rewrite  ^(.*)$ /index.php?s=$1  last;
            break;
        }
    } 

    location ~ \.php(.*)$ {
        try_files $uri =404;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

浏览器访问被定位到/usr/share/nginx/html/

    把root地址写在location ~ \.php(.*)$ {}里面

php的还需要在location ~ .php(.*)$ { 下加入
root /usr/share/nginx/html/project/manage/public;
index index.html index.htm index.php;
