Nginx rewrite 参数和例子

内容来自互联网和平日使用经验，整理一下方便日后参考。

正则表达式匹配，其中：

* ~ 为区分大小写匹配
* ~* 为不区分大小写匹配
* !~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：

* -f和!-f用来判断是否存在文件
* -d和!-d用来判断是否存在目录
* -e和!-e用来判断是否存在文件或目录
* -x和!-x用来判断文件是否可执行

flag标记有：

* last 相当于Apache里的[L]标记，表示完成rewrite
* break 终止匹配, 不再匹配后面的规则
* redirect 返回302临时重定向地址栏会显示跳转后的地址
* 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)

$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

结合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;
}

多目录转成参数

#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;
}

目录对换

#/123456/xxxx -> /xxxx?id=123456
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：

if ($http_user_agent ~ MSIE) {
	rewrite ^(.*)$ /nginx-ie/$1 break;
}

目录自动加“/”

if (-d $request_filename){
	rewrite ^/(.*)([^/])$ http://$host/$1$2/ permanent;
}

禁止htaccess

location ~/\.ht {
	deny all;
}

禁止多个目录

location ~ ^/(cron|templates)/ {
    deny all;
    break;
}

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;

location ~ ^/data {
	deny all;
}

禁止单个目录 不能禁止.log.txt能请求

location /searchword/cron/ {
	deny all;
}

禁止单个文件

location ~ /data/sql/data.sql {
	deny all;
}

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

location ~(favicon.ico) {
    log_not_found off;
    expires 99d;
    break;
}

location ~(robots.txt) {
    log_not_found off;
    expires 7d;
    break;
}

设定某个文件的过期时间;这里为600秒，并不记录访问日志

location ^~ /html/scripts/loadhead_1.js {
    access_log off;
    root /opt/lampp/htdocs/web;
    expires 600;
    break;
}

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

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;
}

只充许固定ip访问网站，并加上密码

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;

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
rewrite ^/job-([0-9]+)-([0-9]+)-([0-9]+)\.html$ /job/$1/$2/jobshow_$3.html last;

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/

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

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

if (-d $request_filename){
	rewrite ^/(.*)([^/])$ http://$host/$1$2/ permanent;
}

知道原因后就好办了，让我手动跳转吧

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

文件和目录不存在的时候重定向：

if (!-e $request_filename) {
	proxy_pass http://127.0.0.1;
}

域名跳转

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;
}

多域名转向

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;
}

三级域名跳转

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

域名镜向

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;
}

某个子目录作镜向

location ^~ /zhaopinhui {
    rewrite ^.+ http://zph.c1gstudio.com/ last;
    break;
}

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;

rewrite ^(.*)/thread-([0-9]+)-([0-9]+)-([0-9]+)\.html$ $1/viewthread.php?tid=$2&extra=page\%3D$4&page=$3 last;

rewrite ^(.*)/space-(username|uid)-(.+)\.html$ $1/space.php?$2=$3 last;
rewrite ^(.*)/tag-(.+)\.html$ $1/tag.php?name=$2 last;

给discuz某版块单独配置域名

{	...
	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;
    }
}

动态参数rewrite

# 以discuz7.2到discuzx1.5为例

if ($query_string ~* tid=([0-9]+)) {
    set $id $1;
    rewrite “^(.*)/viewthread.php$” $1/forum.php?mod=viewthread&tid=$id&extra=page%3D&page=1 last;

nginx 嵌套if nginx不支持if and和多层嵌套if,让我头痛很久,需要通过其它方法实现. 下面是把访问镜像网站cnc.c1gstudio.com的爬虫转到www站.

set $needrewrite ”;
    if ($http_user_agent ~* (baiduspider|googlebot|soso|bing|sogou|yahoo|sohu-search|yodao|YoudaoBot|robozilla|msnbot|MJ12bot|NHN|Twiceler)) {
    set $needrewrite ‘o’;
}
if ($host ~ cnc\.c1gstudio\.com) {
	set $needrewrite “${needrewrite}k”;
}
if ($needrewrite = ok) {
    #return 403;
	rewrite ^(.*) http://www.c1gstudio.com$1 permanent;
}
