nginx + mongodb

<pre name="code" class="python">/确保你已经安装了mongodb和git工具  

 // 下载nginx-gridfs

 注意: 需要特定版本的nginx-gridfs
	
 //安装 nginx
 
    配置 /usr/local/pcre-8.38
	pcre:
    tar -xzvf pcre-8.21.tar.gz
    cd pcre-8.21
    ./configure  && make && make install
	
	
    tar -zxvf nginx-xxx.tar.gz
    cd nginx-xxx
 ./configure --add-module=/usr/local/nginx-gridfs --with-http_stub_status_module --with-pcre=/usr/local/pcre-8.38
     make

     make install

     nginx  -V
nginx: nginx version: nginx/1.0.1
nginx: built by gcc 4.4.7 20120313 (Red Hat 4.4.7-16) (GCC) 
nginx: configure arguments: --add-module=/usr/local/nginx-gridfs --with-http_stub_status_module --with-pcre=/usr/local/pcre-8.38


  注【/usr/local/nginx-gridfs/ 为nginx-gridfs下载目录】

//配置nginx
修改/usr/local/nginx/conf/nginx.conf配置文件。

注：这里说明下，nginx有两个nginx.conf的配置文件，勿配错；
    在nginx.conf中server加入：
       location /pics/ {
          gridfs pics field=filename type=string;
		   mongo 114.35.2.17:27017;
       }

    注【my_app 为mongodb存储文件的数据库名字】

    //启用nginx 
//打开浏览器输入要访问的图片：http://192.168.1.109:28118/gridfs/6b6e567cjw1dmea3323e1j.jpg。 你看到了之前上传的文件

 use tt
这样就创建了一个数据库,如果什么都不操作离开的话,这个库就会被系统删除.所以我们还要执行下面的命令:
db.usr.insert({'name':'tompig'});
db.usr.insert({'name':'tompig1','id':1});


> use tt
switched to db tt
> db.usr.insert({'name':'tompig'});

> db.userInfo.find();

Mongo connection dropped, could not reconnect, 


11.上传文件验证：
sudo  mongofiles put --host localhost --port 27017 --db img --local ~/photo.jpg --type jpg
如果提示Error: need a filename错误，就在--local ~/photo.jpg   xxxname.jpg 添加一个名字即可 （http://hi.baidu.com/manbuzhiwu/item/9adbce5d45405811e6c4a59c）
