配置语法说明:
gridfs DB_NAME [root_collection=ROOT] [field=QUERY_FIELD] [type=QUERY_TYPE] [user=USERNAME] [pass=PASSWORD] gridfs 表示告诉nginx服务器要调用gridfs模块 root_collection= 指定Gridfs collection的前缀. 默认: fs field= 指定用于查询的字段 可以是 _id 和 filename. 默认: _id type= 指定查询的类型,这里支持 objectid, string 和int. 默认: objectid user= 指定数据库的用户名. 默认: NULL, 可省略 pass= 指定数据库的密码. 默认: NULL, 可省略
Nginx配置文件中的具体写法:
location /images/ {
     gridfs images
     field=_id
     type=objectid;
     mongo 127.0.0.1:27017;
}
		
		上传图片
sudo /srv/mongodb/bin/mongofiles put --host localhost --port 27017 --db images --local ~/photo.jpg --type jpg
在浏览器里输入http://localhost/images/photo.jpg 能显示图片就说明成功了
例 63.1. nginx-gridfs
#指定db为static,其它均为默认,默认服务器为本地
location /static/ {
	gridfs static;
}
location /static/ {
        gridfs static
        field=filename
        type=string;
        mongo 127.0.0.1:27017;
}
location /static/ {
	gridfs static;
	    field=filename
	    type=string;
	mongo "foo"
	    172.16.1.1:27017
	    172.16.1.2:27017;
}
location /static/ {
    gridfs static
    root_collection=images
    field=_id
    type=int
    user=admin
    pass=pass;
    mongo 127.0.0.1:27017;
}
