最近在VPS上嘗試配置安裝一個(gè)網(wǎng)站,VPS安裝了LNMP(Linux+Nginx+MySQL+php)在配置重定規(guī)則的時(shí)候經(jīng)常遇到一些問題,直接用Apache的規(guī)則到Nginx下沒起作用。原來Apache 重寫的規(guī)則到nginx上還有一些不太一樣的地方。
這里只是簡單記錄一些學(xué)習(xí)示例,高手略過,新手可以看一下。
Nginx Rewrite規(guī)則相關(guān)指令
Nginx Rewrite規(guī)則相關(guān)指令有if、rewrite、set、return、break等,其中rewrite是最關(guān)鍵的指令。一個(gè)簡單的Nginx Rewrite規(guī)則語法如下:
rewrite ^/b/(.*)\.html /play.php?video=$1 break;
如果加上if語句,示例如下:
if (!-f $request_filename)
rewrite ^/img/(.*)$ /site/$host/images/$1 last;
Nginx與Apache的Rewrite規(guī)則實(shí)例對比
簡單的Nginx和Apache 重寫規(guī)則區(qū)別不大,基本上能夠完全兼容。例如:
Apache Rewrite 規(guī)則:
RewriteRule ^/(mianshi|xianjing)/$ /zl/index.php?name=$1 [L]
RewriteRule ^/ceshi/$ /zl/ceshi.php [L]
RewriteRule ^/(mianshi)_([a-zA-Z]+)/$ /zl/index.php?name=$1_$2 [L]
RewriteRule ^/pingce([0-9]*)/$ /zl/pingce.php?id=$1 [L]
Nginx Rewrite 規(guī)則:
rewrite ^/(mianshi|xianjing)/$ /zl/index.php?name=$1 last;
rewrite ^/ceshi/$ /zl/ceshi.php last;
rewrite ^/(mianshi)_([a-zA-Z]+)/$ /zl/index.php?name=$1_$2 last;
rewrite ^/pingce([0-9]*)/$ /zl/pingce.php?id=$1 last;
由以上示例可以看出,Apache的Rewrite規(guī)則改為Nginx的Rewrite規(guī)則,其實(shí)很簡單:Apache的RewriteRule指令換成Nginx的rewrite指令,Apache的[L]標(biāo)記換成Nginx的last標(biāo)記,中間的內(nèi)容不變。
如果Apache的Rewrite規(guī)則改為Nginx的Rewrite規(guī)則后,使用nginx -t命令檢查發(fā)現(xiàn)nginx.conf配置文件有語法錯(cuò)誤,那么可以嘗試給條件加上引號(hào)。例如一下的Nginx Rewrite規(guī)則會(huì)報(bào)語法錯(cuò)誤:
rewrite ^/([0-9]{5}).html$ /x.jsp?id=$1 last;
加上引號(hào)就正確了:
rewrite “^/([0-9]{5}).html$” /x.jsp?id=$1 last;
Apache與Nginx的Rewrite規(guī)則在URL跳轉(zhuǎn)時(shí)有細(xì)微的區(qū)別:
Apache Rewrite 規(guī)則:
RewriteRule ^/html/tagindex/([a-zA-Z]+)/.*$ /$1/ [R=301,L]
Nginx Rewrite 規(guī)則:
rewrite ^/html/tagindex/([a-zA-Z]+)/.*$ http://$host/$1/ permanent;
以上示例中,我們注意到,Nginx Rewrite 規(guī)則的置換串中增加了“http://$host”,這是在Nginx中要求的。
另外,Apache與Nginx的Rewrite規(guī)則在變量名稱方面也有區(qū)別,例如:
Apache Rewrite 規(guī)則:
RewriteRule ^/user/login/$ /user/login.php?login=1&forward=http://%{HTTP_HOST} [L]
Nginx Rewrite 規(guī)則:
rewrite ^/user/login/$ /user/login.php?login=1&forward=http://$host last;
Apache與Nginx Rewrite 規(guī)則的一些功能相同或類似的指令、標(biāo)記對應(yīng)關(guān)系:
Apache的RewriteCond指令對應(yīng)Nginx的if指令;
Apache的RewriteRule指令對應(yīng)Nginx的rewrite指令;
Apache的[R]標(biāo)記對應(yīng)Nginx的redirect標(biāo)記;
Apache的[P]標(biāo)記對應(yīng)Nginx的last標(biāo)記;
Apache的[R,L]標(biāo)記對應(yīng)Nginx的redirect標(biāo)記;
Apache的[P,L]標(biāo)記對應(yīng)Nginx的last標(biāo)記;
Apache的[PT,L]標(biāo)記對應(yīng)Nginx的last標(biāo)記;
允許指定的域名訪問本站,其他域名一律跳轉(zhuǎn)到http://www.aaa.com
Apache Rewrite 規(guī)則:
RewriteCond %{HTTP_HOST} ^(.*?)\.domain\.com$
RewriteCond %{HTTP_HOST} !^qita\.domain\.com$
RewriteCond %{DOCUMENT_ROOT}/market/%1/index.htm -f
RewriteRule ^/wu/$ /market/%1/index.htm [L]
Nginx的if指令不支持嵌套,也不支持AND、OR等多條件匹配,相比于Apache的RewriteCond,顯得麻煩一些,但是,我們可以通過下一頁的Nginx配置寫法來實(shí)現(xiàn)這個(gè)示例:
Nginx Rewrite 規(guī)則:
if ($host ~* ^(.*?)\.domain\.com$) set $var_wupin_city $1;
set $var_wupin ‘1′;
if ($host ~* ^qita\.domain\.com$)
set $var_wupin ‘0′;
if (!-f $document_root/market/$var_wupin_city/index.htm)
set $var_wupin ‘0′;
if ($var_wupin ~ ‘1′)
rewrite ^/wu/$ /market/$var_wupin_city/index.htm last;
}
rewrite 的語法
語法: rewrite regex replacement flag
默認(rèn): none
作用域: server, location, if
This directive changes URI in accordance with the regular expression and the replacement string. Directives are carried out in order of appearance in the configuration file.
這個(gè)指令根據(jù)表達(dá)式來更改URI,或者修改字符串。指令根據(jù)配置文件中的順序來執(zhí)行。
Be aware that the rewrite regex only matches the relative path instead of the absolute URL. If you want to match the hostname, you should use an if condition, like so:
注意重寫表達(dá)式只對相對路徑有效。如果你想配對主機(jī)名,你應(yīng)該使用if語句。
rewrite只是會(huì)改寫路徑部分的東東,不會(huì)改動(dòng)用戶的輸入?yún)?shù),因此這里的if規(guī)則里面,你無需關(guān)心用戶在瀏覽器里輸入的參數(shù),rewrite后會(huì)自動(dòng)添加的,因此,我們只是加上了一個(gè)?號(hào)和后面我們想要的一個(gè)小小的參數(shù) ***https=1就可以了。
nginx的rewrite規(guī)則參考:
- ~ 為區(qū)分大小寫匹配
- ~* 為不區(qū)分大小寫匹配
- !~和!~*分別為區(qū)分大小寫不匹配及不區(qū)分大小寫不匹
- -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(zhí)行
- last 相當(dāng)于Apache里的[L]標(biāo)記,表示完成rewrite,呵呵這應(yīng)該是最常用的
- break 終止匹配, 不再匹配后面的規(guī)則
- redirect 返回302臨時(shí)重定向 地址欄會(huì)顯示跳轉(zhuǎn)后的地址
- permanent 返回301永久重定向 地址欄會(huì)顯示跳轉(zhuǎn)后的地址
- $args
- $content_length
- $content_type
- $document_root
- $document_uri
- $host
- $http_user_agent
- $http_cookie
- $limit_rate
- $request_body_file
- $request_method
- $remote_addr
- $remote_port
- $remote_user
- $request_filename
- $request_uri
- $query_string
- $scheme
- $server_protocol
- $server_addr
- $server_name
- $server_port
- $uri
結(jié)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=$1 last;
- break;
多目錄轉(zhuǎn)成參數(shù)
abc.domian.com/sort/2 => abc.domian.com/index.php?act=sort&name=abc&id=2
- if ($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=$1 last;
例如下面設(shè)定nginx在用戶使用ie的使用重定向到/nginx-ie目錄下:
- if ($http_user_agent ~ MSIE) {
- rewrite ^(.*)$ /nginx-ie/$1 break;
- }
目錄自動(dòng)加“/”
- if (-d $request_filename){
- rewrite ^/(.*)([^/])$ http://$host/$1$2/ permanent;
- }
禁止htaccess
- location ~/\.ht {
- deny all;
- }
禁止多個(gè)目錄
- location ~ ^/(cron|templates)/ {
- deny all;
- break;
- }
禁止以/data開頭的文件
可以禁止/data/下多級目錄下.log.txt等請求;
- location ~ ^/data {
- deny all;
- }
禁止單個(gè)目錄
不能禁止.log.txt能請求
- location /searchword/cron/ {
- deny all;
- }
禁止單個(gè)文件
- location ~ /data/sql/data.sql {
- deny all;
- }
給favicon.ico和robots.txt設(shè)置過期時(shí)間;
這里為favicon.ico為99天,robots.txt為7天并不記錄404錯(cuò)誤日志
- location ~(favicon.ico) {
- log_not_found off;
- expires 99d;
- break;
- }
- location ~(robots.txt) {
- log_not_found off;
- expires 7d;
- break;
- }
設(shè)定某個(gè)文件的過期時(shí)間;這里為600秒,并不記錄訪問日志
- location ^~ /html/scripts/loadhead_1.js {
- access_log off;
- root /opt/lampp/htdocs/web;
- expires 600;
- break;
- }
文件反盜鏈并設(shè)置過期時(shí)間
這里的return 412 為自定義的http狀態(tài)碼,默認(rèn)為403,方便找出正確的盜鏈的請求
“rewrite ^/ http://leech.divmy.com/leech.gif;”顯示一張防盜鏈圖片
“access_log off;”不記錄訪問日志,減輕壓力
“expires 3d”所有文件3天的瀏覽器緩存
- location ~* ^.+\.(jpg|jpeg|gif|png|swf|rar|zip|css|js)$ {
- valid_referers none blocked *.c1gstudio.com *.c1gstudio.net localhost 208.97.167.194;
- if ($invalid_referer) {
- rewrite ^/ http://leech.divmy.com/leech.gif;
- return 412;
- break;
- }
- access_log off;
- root /opt/lampp/htdocs/web;
- expires 3d;
- break;
- }
只充許固定ip訪問網(wǎng)站,并加上密碼
- root /opt/htdocs/www;
- allow 208.97.167.194;
- allow 222.33.1.2;
- allow 231.152.49.4;
- deny all;
- auth_basic “C1G_ADMIN”;
- auth_basic_user_file htpasswd;
將多級目錄下的文件轉(zhuǎn)成一個(gè)文件,增強(qiáng)seo效果
/job-123-456-789.html 指向/job/123/456/789.html
- rewrite ^/job-([0-9]+)-([0-9]+)-([0-9]+)\.html$ /job/$1/$2/jobshow_$3.html last;
將根目錄下某個(gè)文件夾指向2級目錄
如/shanghaijob/ 指向 /area/shanghai/
如果你將last改成permanent,那么瀏覽器地址欄顯是/location/shanghai/
- rewrite ^/([0-9a-z]+)job/(.*)$ /area/$1/$2 last;
上面例子有個(gè)問題是訪問/shanghai 時(shí)將不會(huì)匹配
- rewrite ^/([0-9a-z]+)job$ /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(shí)地址是/area/shanghia/list_1.html會(huì)變成/list_1.html,導(dǎo)至無法訪問。
那我加上自動(dòng)跳轉(zhuǎn)也是不行咯
(-d $request_filename)它有個(gè)條件是必需為真實(shí)目錄,而我的rewrite不是的,所以沒有效果
- if (-d $request_filename){
- rewrite ^/(.*)([^/])$ http://$host/$1$2/ permanent;
- }
知道原因后就好辦了,讓我手動(dòng)跳轉(zhuǎn)吧
- rewrite ^/([0-9a-z]+)job$ /$1job/ permanent;
- rewrite ^/([0-9a-z]+)job/(.*)$ /area/$1/$2 last;
文件和目錄不存在的時(shí)候重定向:
- if (!-e $request_filename) {
- proxy_pass http://127.0.0.1;
- }
域名跳轉(zhuǎn)
- server
- {
- listen 80;
- server_name jump.88dgw.com;
- index index.html index.htm index.php;
- root /opt/lampp/htdocs/www;
- rewrite ^/ http://www.88dgw.com/;
- access_log off;
- }
多域名轉(zhuǎn)向
三級域名跳轉(zhuǎn)
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.divmy.com/$1 last;
- access_log off;
- }
某個(gè)子目錄作鏡向
discuz ucenter home (uchome) rewrite
- rewrite ^/(space|network)-(.+)\.html$ /$1.php?rewrite=$2 last;
- rewrite ^/(space|network)\.html$ /$1.php last;
- rewrite ^/([0-9]+)$ /space.php?uid=$1 last;
discuz 7 rewrite
- rewrite ^(.*)/archiver/((fid|tid)-[\w\-]+\.html)$ $1/archiver/index.php?$2 last;
- rewrite ^(.*)/forum-([0-9]+)-([0-9]+)\.html$ $1/forumdisplay.php?fid=$2&page=$3 last;
- rewrite ^(.*)/thread-([0-9]+)-([0-9]+)-([0-9]+)\.html$ $1/viewthread.php?tid=$2&extra=page\%3D$4&page=$3 last;
- rewrite ^(.*)/profile-(username|uid)-(.+)\.html$ $1/viewpro.php?$2=$3 last;
- rewrite ^(.*)/space-(username|uid)-(.+)\.html$ $1/space.php?$2=$3 last;
- rewrite ^(.*)/tag-(.+)\.html$ $1/tag.php?name=$2 last;
給discuz某版塊單獨(dú)配置域名
discuz ucenter 頭像 rewrite 優(yōu)化
