正則表達式匹配，其中：
* ~ 爲區分大小寫匹配
* ~* 爲不區分大小寫匹配
* !~和!~*分別爲區分大小寫不匹配及不區分大小寫不匹配
文件及目錄匹配，其中：
* -f和!-f用來判斷是否存在文件
* -d和!-d用來判斷是否存在目錄
* -e和!-e用來判斷是否存在文件或目錄
* -x和!-x用來判斷文件是否可執行
flag標記有：
* last 相當於Apache裏的[L]標記，表示完成rewrite
* break 終止匹配, 不再匹配後面的規則
* redirect 返回302臨時重定向 地址欄會顯示跳轉後的地址
* permanent 返回301永久重定向 地址欄會顯示跳轉後的地址
一些可用的全局變量有，可以用做條件判斷(待補全)

結合QeePHP的例子
if (!-d $request_filename) {
rewrite ^/([a-z-A-Z]+)/([a-z-A-Z]+)/?(.*)$ /index.php?namespace=user&controller=$1&action=$2&$3 last;
rewrite ^/([a-z-A-Z]+)/?$ /index.php?namespace=user&controller=$1 last;
break;
多目錄轉成參數
abc.domian.com/sort/2 => abc.domian.com/index.php?act=sort&name=abc&id=2
if ($host ~* (.*)/.domain/.com) {
set $sub_name $1;
rewrite ^/sort//(/d+)//?$ /index.php?act=sort&cid=$sub_name&id=$1 last;
}
目錄對換
/123456/xxxx -> /xxxx?id=123456
rewrite ^/(/d+)/(.+)/ /$2?id=$1 last;
例如下面設定nginx在用戶使用ie的使用重定向到/nginx-ie目錄下：
if ($http_user_agent ~ MSIE) {
rewrite ^(.*)$ /nginx-ie/$1 break;
}
目錄自動加“/”
if (-d $request_filename){
rewrite ^/(.*)([^/])$ http://$host/$1$2/ permanent;
}
禁止htaccess
location ~//.ht {
deny all;
}
禁止多個目錄
location ~ ^/(cron|templates)/ {
deny all;
break;
}
禁止以/data開頭的文件
可以禁止/data/下多級目錄下.log.txt等請求;
location ~ ^/data {
deny all;
}
禁止單個目錄
不能禁止.log.txt能請求
location /searchword/cron/ {
deny all;
}
禁止單個文件
location ~ /data/sql/data.sql {
deny all;
}
給favicon.ico和robots.txt設置過期時間;
這裏爲favicon.ico爲99天,robots.txt爲7天並不記錄404錯誤日誌
location ~(favicon.ico) {
log_not_found off;
expires 99d;
break;
}
location ~(robots.txt) {
log_not_found off;
expires 7d;
break;
}
設定某個文件的過期時間;這裏爲600秒，並不記錄訪問日誌
location ^~ /html/scripts/loadhead_1.js {
access_log off;
root /opt/lampp/htdocs/web;
expires 600;
break;
}
文件反盜鏈並設置過期時間
這裏的return 412 爲自定義的http狀態碼，默認爲403，方便找出正確的盜鏈的請求
“rewrite ^/ http://leech.c1gstudio.com/leech.gif;”顯示一張防盜鏈圖片
“access_log off;”不記錄訪問日誌，減輕壓力
“expires 3d”所有文件3天的瀏覽器緩存
location ~* ^.+/.(jpg|jpeg|gif|png|swf|rar|zip|css|js)$ {
valid_referers none blocked *.c1gstudio.com *.c1gstudio.net localhost 208.97.167.194;
if ($invalid_referer) {
rewrite ^/ http://leech.c1gstudio.com/leech.gif;
return 412;
break;
}
access_log off;
root /opt/lampp/htdocs/web;
expires 3d;
break;
}
只充許固定ip訪問網站，並加上密碼
root /opt/htdocs/www;
allow 208.97.167.194;
allow 222.33.1.2;
allow 231.152.49.4;
deny all;
auth_basic "C1G_ADMIN";
auth_basic_user_file htpasswd;
將多級目錄下的文件轉成一個文件，增強seo效果
/job-123-456-789.html 指向/job/123/456/789.html
rewrite ^/job-([0-9]+)-([0-9]+)-([0-9]+)/.html$ /job/$1/$2/jobshow_$3.html last;
將根目錄下某個文件夾指向2級目錄
如/shanghaijob/ 指向 /area/shanghai/
如果你將last改成permanent，那麼瀏覽器地址欄顯是/location/shanghai/
rewrite ^/([0-9a-z]+)job/(.*)$ /area/$1/$2 last;
上面例子有個問題是訪問/shanghai 時將不會匹配
rewrite ^/([0-9a-z]+)job$ /area/$1/ last;
rewrite ^/([0-9a-z]+)job/(.*)$ /area/$1/$2 last;
這樣/shanghai 也可以訪問了，但頁面中的相對鏈接無法使用，
如./list_1.html真實地址是/area/shanghia/list_1.html會變成/list_1.html,導至無法訪問。
那我加上自動跳轉也是不行咯
(-d $request_filename)它有個條件是必需爲真實目錄，而我的rewrite不是的，所以沒有效果
if (-d $request_filename){
rewrite ^/(.*)([^/])$ http://$host/$1$2/ permanent;
}
知道原因後就好辦了，讓我手動跳轉吧
rewrite ^/([0-9a-z]+)job$ /$1job/ permanent;
rewrite ^/([0-9a-z]+)job/(.*)$ /area/$1/$2 last;
文件和目錄不存在的時候重定向：
if (!-e $request_filename) {
proxy_pass http://127.0.0.1;
}
域名跳轉
server
{
listen 80;
server_name jump.c1gstudio.com;
index index.html index.htm index.php;
root /opt/lampp/htdocs/www;
rewrite ^/ http://www.c1gstudio.com/;
access_log off;
}
多域名轉向
server_name www.c1gstudio.com www.c1gstudio.net;
index index.html index.htm index.php;
root /opt/lampp/htdocs;
if ($host ~ "c1gstudio/.net") {
rewrite ^(.*) http://www.c1gstudio.com$1 permanent;
}
三級域名跳轉
if ($http_host ~* "^(.*)/.i/.c1gstudio/.com$") {
rewrite ^(.*) http://top.yingjiesheng.com$1;
break;
}
域名鏡向
server
{
listen 80;
server_name mirror.c1gstudio.com;
index index.html index.htm index.php;
root /opt/lampp/htdocs/www;
rewrite ^/(.*) http://www.c1gstudio.com/$1 last;
access_log off;
}
某個子目錄作鏡向
location ^~ /zhaopinhui {
rewrite ^.+ http://zph.c1gstudio.com/ last;
break;
}
discuz ucenter home (uchome) rewrite
rewrite ^/(space|network)-(.+)/.html$ /$1.php?rewrite=$2 last;

給discuz某版塊單獨配置域名
server_name bbs.c1gstudio.com news.c1gstudio.com;
location = / {
if ($http_host ~ news/.c1gstudio.com$) {
rewrite ^.+ http://news.c1gstudio.com/forum-831-1.html last;
break;
