1. server {
2. listen 23.88.229.213:80;
3. server_name www.world-alive.win;
4. image_filter_sharpen 80;
5. root /home/data/www/htdocs/world-alive.win;
6. access_log /var/log/nginx/www.world-alive.win-access.log;
8. location ~* ^/resize {
9. ### 生成缩略图的路径 (类似于站点根目录)
10. alias /data/site_cache/world-alive.win;
11. ### 默认 宽度 高度
12. set $width 150;
13. set $height 100;
14. ## 默认的 _$1x$2 也就是 _150x100
15. set $dimens “”;
16. ### 当在浏览器或者说url 输入 resize_400x400 自动匹配url中的width height
17. if ($uri ~* “^/resize_(\d+)x(\d+)/(.*)” ) {
18. set $width $1;
19. set $height $2;
20. set $image_path $3;
21. set $demins “_$1x$2”;
22. }
24. ### 当在浏览器或者说url 输入 resize 即不带指定的 width height
25. if ($uri ~* “^/resize/(.*)” ) {
26. set $image_path $1;
27. }
29. set $image_uri _resize/$image_path?width=$width&height=$height;
31. if (!-f $request_filename) {
32. proxy_pass http://23.88.229.213/$image_uri;
33. break;
34. }
35. ### 生成缩略图的具体路径 指定长宽的 resize_**x**/$image_path 不指定 resize/$image_path
36. ### resize$demins 中 resize 为自定义
37. proxy_store /data/site_cache/world-alive.win/resize$demins/$image_path;
38. proxy_store_access user:rw group:rw all:r;
39. proxy_set_header Host $host;
40. #expires 30d;
41. access_log off;
42. }
44. location /_resize {
45. ## 指定图片所在的位置 如果指在根目录 则生成缩略图 /resize$demins/$image_path; 中$image_path 会带上图片路径的文件夹的名称 例如 resize_100x100/image/001.jpg 如果指定图片位置 47行注释那句 则产生的路径为 resize_100x100/001.jpg ;
46. alias /home/data/www/htdocs/world-alive.win;
47. #alias /home/data/www/htdocs/world-alive.win/image;
48. image_filter resize $arg_width $arg_height;
49. image_filter_jpeg_quality 95;
50. access_log off;
51. }
53. ####### 当你还有其他的目录的图片需要生成缩略图 上面的配置你需要修改的为下列红色部分
55. location ~* ^/pimg {
56. alias /usr/local/cache/img;
57. set $width 150;
58. set $height 100;
59. set $dimens “”;
60. if ($uri ~* “^/pimg_(\d+)x(\d+)/(.*)” ) {
61. set $width $1;
62. set $height $2;
63. set $image_path $3;
64. set $demins “_$1x$2”;
65. }
66. if ($uri ~* “^/pimg/(.*)” ) {
67. set $image_path $1;
68. }
69. set $image_uri _iiresize/$image_path?width=$width&height=$height;
70. if (!-f $request_filename) {
71. proxy_pass http://23.88.229.213/$image_uri;
72. break;
73. }
74. proxy_store /usr/local/cache/img/pimg$demins/$image_path;
75. proxy_store_access user:rw group:rw all:r;
76. proxy_set_header Host $host;
77. #expires 30d;
78. access_log off;
79. }
80. location /_iiresize {
81. alias /home/data/www/htdocs/world-alive.win/picture;
82. image_filter resize $arg_width $arg_height;
83. image_filter_jpeg_quality 95;
84. access_log off;
85. }

## 提醒注意 ：  能力问题吧 有几个地方更改之后 各种错
## 一     if ($uri ~* “^/resize_(\d+)x(\d+)/(.*)” )   这里前缀可以改  但是我改成 /resize/(\d+)x(\d+)/(.*)  这样的方式我将出现 415 的报错
## 二   location /_resize {   如果在 _ 前面加前缀  例如 img_resize   就会得不到图片
## 理论上这应该都是行得通的才对 ， 以后有时间在做测试
