nginx rewrite 添加请求头信息 nginx rewrite 参数

正则表达式匹配,其中:
1. * ~ 为区分大小写匹配
2. * ~* 为不区分大小写匹配
3. * !~和!~*分别为区分大小写不匹配及不区分大小写不匹配
文件及目录匹配,其中:
1. * -f和!-f用来判断是否存在文件
2. * -d和!-d用来判断是否存在目录
3. * -e和!-e用来判断是否存在文件或目录
4. * -x和!-x用来判断文件是否可执行
flag标记有:
1. * last 相当于Apache里的[L]标记,表示完成rewrite
2. * break 终止匹配, 不再匹配后面的规则
3. * redirect 返回302临时重定向 地址栏会显示跳转后的地址
4. * permanent 返回301永久重定向 地址栏会显示跳转后的地址
一些可用的全局变量有,可以用做条件判断(待补全)
1. $args
2. $content_length
3. $content_type
4. $document_root
5. $document_uri
6. $host
7. $http_user_agent
8. $http_cookie
9. $limit_rate
10. $request_body_file
11. $request_method
12. $remote_addr
13. $remote_port
14. $remote_user
15. $request_filename
16. $request_uri
17. $query_string
18. $scheme
19. $server_protocol
20. $server_addr
21. $server_name
22. $server_port
23. $uri
结合QeePHP的例子
1. if (!-d $request_filename) {

2. rewrite ^/([a-z-A-Z]+)/([a-z-A-Z]+)/?(.*)$ /index.php?namespace=user&controller=&action=& last;
3. rewrite ^/([a-z-A-Z]+)/?$ /index.php?namespace=user&controller= last;
4. break;
多目录转成参数
abc.domian.com/sort/2 => abc.domian.com/index.php?act=sort&name=abc&id=21. if ($host ~* (.*)\.domain\.com) {

2. set $sub_name ;   
3. rewrite ^/sort\/(\d+)\/?$ /index.php?act=sort&cid=$sub_name&id= last;
4. }
目录对换
/123456/xxxx -> /xxxx?id=1234561. rewrite ^/(\d+)/(.+)/ /?id= last;
例如下面设定nginx在用户使用ie的使用重定向到/nginx-ie目录下:
1. if ($http_user_agent ~ MSIE) {

2. rewrite ^(.*)$ /nginx-ie/ break;
3. }
目录自动加“/”
1. if (-d $request_filename){

2. rewrite ^/(.*)([^/])$ http://$host// permanent;
3. }
禁止htaccess
1. location ~/\.ht {

2.          deny all;
3.      }
禁止多个目录
1. location ~ ^/(cron|templates)/ {

2.          deny all;
3. break;
4.      }
禁止以/data开头的文件
可以禁止/data/下多级目录下.log.txt等请求;1. location ~ ^/data {

2.          deny all;
3.      }
禁止单个目录
不能禁止.log.txt能请求1. location /searchword/cron/ {

2.          deny all;
3.      }
禁止单个文件
1. location ~ /data/sql/data.sql {

2.          deny all;
3.      }
给favicon.ico和robots.txt设置过期时间;
这里为favicon.ico为99天,robots.txt为7天并不记录404错误日志1. location ~(favicon.ico) {

2.                  log_not_found off;
3. expires 99d;
4. break;
5.      }
6.      location ~(robots.txt) {

7.                  log_not_found off;
8. expires 7d;
9. break;
10.      }
设定某个文件的过期时间;这里为600秒,并不记录访问日志
1. location ^~ /html/scripts/loadhead_1.js {

2.                  access_log   off;
3.                  root /opt/lampp/htdocs/web;
4. expires 600;
5. break;
6.        }
文件反盗链并设置过期时间
这里的return 412 为自定义的http状态码,默认为403,方便找出正确的盗链的请求
“rewrite ^/ http://leech.c1gstudio.com/leech.gif;”显示一张防盗链图片
“access_log off;”不记录访问日志,减轻压力
“expires 3d”所有文件3天的浏览器缓存1. location ~* ^.+\.(jpg|jpeg|gif|png|swf|rar|zip|css|js)$ {

2. valid_referers none blocked *.c1gstudio.com *.c1gstudio.net localhost 208.97.167.194;
3. if ($invalid_referer) {

4.     rewrite ^/ http://leech.c1gstudio.com/leech.gif;
5.     return 412;
6.     break;
7. }
8.                  access_log   off;
9.                  root /opt/lampp/htdocs/web;
10. expires 3d;
11. break;
12.      }
只充许固定ip访问网站,并加上密码
1. root  /opt/htdocs/www;
2. allow   208.97.167.194;
3. allow   222.33.1.2;
4. allow   231.152.49.4;
5. deny    all;
6. auth_basic “C1G_ADMIN”;
7. auth_basic_user_file htpasswd;
将多级目录下的文件转成一个文件,增强seo效果
/job-123-456-789.html 指向/job/123/456/789.html1. rewrite ^/job-([0-9]+)-([0-9]+)-([0-9]+)\.html$ /job///jobshow_.html last;
将根目录下某个文件夹指向2级目录
如/shanghaijob/ 指向 /area/shanghai/
如果你将last改成permanent,那么浏览器地址栏显是/location/shanghai/1. rewrite ^/([0-9a-z]+)job/(.*)$ /area// last;
上面例子有个问题是访问/shanghai 时将不会匹配
1. rewrite ^/([0-9a-z]+)job$ /area// last;
2. rewrite ^/([0-9a-z]+)job/(.*)$ /area// last;
这样/shanghai 也可以访问了,但页面中的相对链接无法使用,
如./list_1.html真实地址是/area/shanghia/list_1.html会变成/list_1.html,导至无法访问。
那我加上自动跳转也是不行咯
(-d $request_filename)它有个条件是必需为真实目录,而我的rewrite不是的,所以没有效果1. if (-d $request_filename){

2. rewrite ^/(.*)([^/])$ http://$host// permanent;
3. }
知道原因后就好办了,让我手动跳转吧
1. rewrite ^/([0-9a-z]+)job$ /job/ permanent;
2. rewrite ^/([0-9a-z]+)job/(.*)$ /area// last;
文件和目录不存在的时候重定向:
1. if (!-e $request_filename) {

2. proxy_pass http://127.0.0.1;
3. }
域名跳转
1. server
2.      {

3.              listen       80;
4.              server_name  jump.c1gstudio.com;
5.              index index.html index.htm index.php;
6.              root  /opt/lampp/htdocs/www;
7.              rewrite ^/ http://www.c1gstudio.com/;
8.              access_log  off;
9.      }
多域名转向
1. server_name  www.c1gstudio.com www.c1gstudio.net;
2.              index index.html index.htm index.php;
3.              root  /opt/lampp/htdocs;
4. if ($host ~ “c1gstudio\.net”) {

5. rewrite ^(.*) http://www.c1gstudio.com permanent;
6. }
三级域名跳转
1. if ($http_host ~* “^(.*)\.i\.c1gstudio\.com$”) {

2. rewrite ^(.*) http://top.yingjiesheng.com;
3. break;
4. }
域名镜向
1. server
2.      {

3.              listen       80;
4.              server_name  mirror.c1gstudio.com;
5.              index index.html index.htm index.php;
6.              root  /opt/lampp/htdocs/www;
7.              rewrite ^/(.*) http://www.c1gstudio.com/ last;
8.              access_log  off;
9.      }
某个子目录作镜向
1. location ^~ /zhaopinhui {

2.   rewrite ^.+ http://zph.c1gstudio.com/ last;
3.   break;
4.      }
discuz ucenter home (uchome) rewrite
1. rewrite ^/(space|network)-(.+)\.html$ /.php?rewrite= last;
2. rewrite ^/(space|network)\.html$ /.php last;
3. rewrite ^/([0-9]+)$ /space.php?uid= last;
discuz 7 rewrite
1. rewrite ^(.*)/archiver/((fid|tid)-[\w\-]+\.html)$ /archiver/index.php? last;
2. rewrite ^(.*)/forum-([0-9]+)-([0-9]+)\.html$ /forumdisplay.php?fid=&page= last;
3. rewrite ^(.*)/thread-([0-9]+)-([0-9]+)-([0-9]+)\.html$ /viewthread.php?tid=&extra=page\%3D&page= last;
4. rewrite ^(.*)/profile-(username|uid)-(.+)\.html$ /viewpro.php?= last;
5. rewrite ^(.*)/space-(username|uid)-(.+)\.html$ /space.php?= last;
6. rewrite ^(.*)/tag-(.+)\.html$ /tag.php?name= last;
给discuz某版块单独配置域名
1. server_name  bbs.c1gstudio.com news.c1gstudio.com;
2.      location = / {

3.         if ($http_host ~ news\.c1gstudio.com$) {

4.   rewrite ^.+ http://news.c1gstudio.com/forum-831-1.html last;
5.   break;
6. }
7.      }

2.      location ~ .*\.php?$
3.      {

4.   #fastcgi_pass  unix:/tmp/php-cgi.sock;
