  • About Godaddy AD

    Remove AD:

         Add <script>  in HTML file, just after the tag of </body>

        example:

        <html>
        <body>
            <h1>It works!</h1>
            <p>This is the default web page for this server.</p>
           <p>The web server software is running but no content has been added, yet.</p>

  • nginx rewrite规则和参考

    http://edu.codepub.com/show.php?contentid=25477

     

    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&amp;controller=$1&amp;action=$2&amp;$3 last;
    3. rewrite ^/([a-z-A-Z]+)/?$ /index.php?namespace=user&amp;controller=$1 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=2

    1. if ($host ~* (.*).domain.com) {
    2. set $sub_name $1;   
    3. rewrite ^/sort/(d+)/?$ /index.php?act=sort&cid=$sub_name&id=$1 last;
    4. }

    目录对换
    /123456/xxxx -> /xxxx?id=123456

    1. rewrite ^/(d+)/(.+)/ /$2?id=$1 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/$1 break;
    3. }

    目录自动加“/”

    1. if (-d $request_filename){
    2. rewrite ^/(.*)([^/])$ http://$host/$1$2/ 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.  
    7.      location ~(robots.txt) {
    8.                  log_not_found off;
    9. expires 7d;
    10. break;
    11.      }

    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.html

    1. rewrite ^/job-([0-9]+)-([0-9]+)-([0-9]+).html$ /job/$1/$2/jobshow_$3.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/$1/$2 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/$1/ last;
    2. rewrite ^/([0-9a-z]+)job/(.*)$ /area/$1/$2 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/$1$2/ permanent;
    3. }

    知道原因后就好办了，让我手动跳转吧

    1. rewrite ^/([0-9a-z]+)job$ /$1job/ permanent;
    2. rewrite ^/([0-9a-z]+)job/(.*)$ /area/$1/$2 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$1 permanent;
    6. }

    三级域名跳转

    1. if ($http_host ~* “^(.*).i.c1gstudio.com$”) {
    2. rewrite ^(.*) http://top.yingjiesheng.com$1;
    3. break;
    4. }

    域名镜向

    1. server
    2.      {
    3.              listen       80;
    4.              server_name  mirror.c1gstudio.com;

    6.              root  /opt/lampp/htdocs/www;
    7.              rewrite ^/(.*) http://www.c1gstudio.com/$1 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.      }

    6. rewrite ^(.*)/tag-(.+).html$ $1/tag.php?name=$2 last;
