PHP可以直接读取MongoDB GridFS中的图片并显示到页面中,但对PHP的压力就大了。偶然机会,了解到Nginx可以代理访问,实现过程如下:

1、工具准备

安装一些必要的编译工具及库,这里是直接从“编译安装LNMP”系列教材中摘取的,有点冗余。

yum -y install make apr* autoconf automake curl-devel gcc gcc-c++ zlib-devel openssl openssl-devel pcre-devel gd kernel keyutils patch perl kernel-headers compat* mpfr cpp glibc libgomp libstdc++-devel ppl cloog-ppl keyutils-libs-devel libcom_err-devel libsepol-devel libselinux-devel krb5-devel libXpm* freetype libjpeg* libpng* php-common php-gd ncurses* libtool* libxml2 libxml2-devel patch gettext glib2-devel bzip2-devel libuuid-devel docbook-style-xsl libxslt-devel gzip-devel

 

2、源码准备

(1)Nginx基础软件

Nginx1.4.4

http://nginx.org/download/nginx-1.4.4.tar.gz

pcre(支持Nginx地址重写)

ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.33.tar.gz

gzip(页面压缩)

http://zlib.net/zlib-1.2.8.tar.gz

openssl(https安全支持组件)

http://www.openssl.org/source/openssl-1.0.1e.tar.gz

(2)nginx-gridfs插件、MongoDB访问驱动 mongodb-mongo-c-driver

https://github.com/mdirolf/nginx-gridfs/archive/v0.8.tar.gz

https://github.com/mongodb/mongo-c-driver/archive/v0.3.1.tar.gz

 

3、编译安装Shell脚本

install.sh

PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:~/bin
export PATH

#需要切换到root用户
if [[ $EUID -ne 0 ]]; then
	echo "This script must be run as root"
	exit 1
fi

ROOT_PATH=/usr/local/src/2
mkdir $ROOT_PATH
rm -rf $ROOT_PATH/*

make && make install


#添加nginx用户及用户组
groupadd www  #添加nginx用户组及用户
useradd -g www -s /usr/sbin/nologin www  #不让nginx用户直接登录

 

4、配置nginx-gridfs

vim /usr/local/nginx/conf/nginx.conf

在 server 节点中添加 location 节点

location /pics/ {
	gridfs  edusns
	root_collection=sns_attach
	field=filename
	type=string;
	user=eduadmin
	pass=eduadmin$123;
	mongo  172.8.8.153:27017;
}

注意,如果不指定 field,默认为 MongoDB 的自增ID,且type为int

参数介绍:

gridfs:nginx识别插件的关键字

edusns:db名

[root_collection]: 选择collection,如root_collection=blog, mongod就会去找blog.files与blog.chunks两个块,默认是fs

[field]: 查询字段,保证mongdb里有这个字段名,支持_id, filename, 可省略, 默认是_id

[type]: 解释field的数据类型,支持objectid, int, string, 可省略, 默认是int

[user]: 用户名, 可省略

[pass]: 密码, 可省略

mongo: mongodb url

 

5、给MongoDB上传图片 

/usr/local/mongodb/bin/mongofiles put --host 172.8.8.153 --port 27017 --db edusns --local ~/photo.jpg --type jpg

在浏览器里输入http://localhost/pics/photo.jpg 能下载图片就说明成功了!

 

6、启动Nginx

/usr/local/nginx/nginx

 

存在的问题:浏览器端不能缓存,每次请求都要从服务器获取
