现在随着各终端的出现(手机，ipad等平板),以及各种终端的手机分辨率和尺寸都不同，现在手机用户流量都是宝,网上出现了各种各样的生成缩略图功能的架构，有使用php实时生成缩略图的，也有用nginx + lua实现的，上节我也讲到了使用nginx生成缩略图，但是用户每次访问都需要生成一次，会给cpu和硬盘带来比较大的压力，今天带来了另外一种方式，这次使用nginx将原图生成缩略图到硬盘上.看我的配置

1、首先创建好cache目录

[root@masterserver ~]# mkdir -p /data/stie_cache 
[root@masterserver ~]#

2、修改nginx配置，增加如下内容

location ~* ^/resize {
root /data/site_cache/$server_name;
set $width 150;
set $height 100;
set $dimens "";
if ($uri ~* "^/resize_(\d+)x(\d+)/(.*)" ) {
set $width $1;
set $height $2;
set $image_path $3;
set $demins "_$1x$2";
}
if ($uri ~* "^/resize/(.*)" ) {
set $image_path $1;
}
set $image_uri image_resize/$image_path"htmlcode">

[root@masterserver conf]# cat nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name localhost;
location / {
root html;
index index.html index.htm;
image on;
image_output on;
}
location ~* ^/resize {
root /data/site_cache/$server_name;
set $width 150;
set $height 100;
set $dimens "";
if ($uri ~* "^/resize_(\d+)x(\d+)/(.*)" ) {
set $width $1;
set $height $2;
set $image_path $3;
set $demins "_$1x$2";
}
if ($uri ~* "^/resize/(.*)" ) {
set $image_path $1;
}
set $image_uri image_resize/$image_path"http://10.0.0.10/resize_100x100/image/1.jpg">http://10.0.0.10/resize_100x100/image/1.jpg.


3、这个请求进入了location ~* ^/resize,接着判断image_path这个目录下是否存在这张图片,如果存在直接放回给用户,


4、不存在那么跳转到http://10.0.0.10/image_resize/image/1.jpg?width=100&height=100;


5、location /image_resize根据传入的width和height执行缩略功能,并且设置图像质量为75


6、接着生成文件到/data/site_cache/10.0.0.10/resize_100x100/image/1.jpg


7、并且返回图片给用户


8、nginx生成缩略图到硬盘上的功能到这里就结束了
