1、rewrite语法：
指令语法：rewrite regex replacement[flag];
默认值：none
应用位置：server、location、if
rewrite是实现URL重定向的重要指令，他根据regex(正则表达式)来匹配内容跳转到replacement，结尾是flag标记
简单的小例子：
常用正则表达式：
rewrite 最后一项flag参数：
2、应用场景：
调整用户浏览的URL，看起来规范为了让搜索引擎收录网站内容，让用户体验更好网站更换新域名后根据特殊的变量、目录、客户端信息进行跳转3、常用301跳转：
之前我们通过用起别名的方式做到了不同地址访问同一个虚拟主机的资源，现在我们可以用一个更好的方式做到这一点，那就是跳转的方法
还是用虚拟主机为例子，修改配置文件brian.conf：
[root@Nginx www_date]# cat brian.conf server {# 添加个server区块做跳转listen80;server_name ;rewrite ^/(.*) /$1 permanent;}server {listen 80;server_name ;location / {root html/brian;index index.html index.htm;}access_log logs/brian.log main gzip buffer=128k flush=5s; error_page 500 502 503 504 /50x.html;location = /50x.html {root html;}}
检查语法：
[root@Nginx conf]# [root@Nginx conf]# ../sbin/nginx -tnginx: the configuration file /opt/nginx//conf/nginx.conf syntax is oknginx: configuration file /opt/nginx//conf/nginx.conf test is successful
平滑重启：
windows测试效果：
4、域名跳转：
我们不仅可以做相同虚拟主机的资源域名跳转，也能做不同虚拟主机的域名跳转，我们下面就跳转下当访问域名的时候跳转到的页面：
修改虚拟主机的brian.conf配置文件：
[root@Nginx www_date]# cat brian.conf server {listen 80;server_name ;location / {root html/brian;index index.html index.htm;}if ( $http_host ~* "^(.*)") {set $domain $1;rewrite ^(.*) break;}access_log logs/brian.log main gzip buffer=128k flush=5s; error_page 500 502 503 504 /50x.html;location = /50x.html {root html;}}
windows测试：(访问 跳转到了)
nginx rewrite 参数和例子+常用Rewrite伪静态法则
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=$1 last;
break;
多目录转成参数
/sort/2 => /index.php?act=sort&name=abc&id=2
if ($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$2/ permanent;
}
禁止htaccess
location ~//.ht {
deny all;
}
禁止多个目录
location ~ ^/(cron|templates)/ {
deny all;
break;
}
禁止以/data开头的文件
可以禁止/data/下多级目录下.log.txt等请求;
location ~ ^/data {
deny all;
}
禁止单个目录
不能禁止.log.txt能请求
location /searchword/cron/ {
deny all;
}
禁止单个文件
location ~ /data/sql/data.sql {
deny all;
}
给favicon.ico和robots.txt设置过期时间;
这里为favicon.ico为99天,robots.txt为7天并不记录404错误日志
location ~(favicon.ico) {
log_not_found off;
expires 99d;
break;
}
location ~(robots.txt) {
log_not_found off;
expires 7d;
break;
}
设定某个文件的过期时间;这里为600秒，并不记录访问日志
location ^~ /html/scripts/loadhead_1.js {
access_logoff;
root /opt/lampp/htdocs/web;
expires 600;
break;
}
文件反盗链并设置过期时间
这里的return 412 为自定义的http状态码，默认为403，方便找出正确的盗链的请求
“rewrite ^/ /leech.gif;”显示一张防盗链图片
“access_log off;”不记录访问日志，减轻压力
“expires 3d”所有文件3天的浏览器缓存
location ~* ^.+/.(jpg|jpeg|gif|png|swf|rar|zip|css|js)$ {
valid_referers none blocked *. *. localhost 208.97.167.194;
if ($invalid_referer) {
rewrite ^/ /leech.gif;
return 412;
break;
}
access_logoff;
root /opt/lampp/htdocs/web;
expires 3d;
break;
}
只充许固定ip访问网站，并加上密码
root/opt/htdocs/www;
allow208.97.167.194;
allow222.33.1.2;
allow231.152.49.4;
denyall;
auth_basic "C1G_ADMIN";
auth_basic_user_file htpasswd;
将多级目录下的文件转成一个文件，增强seo效果
/job-123-456-789.html 指向/job/123/456/789.html
rewrite ^/job-([0-9]+)-([0-9]+)-([0-9]+)/.html$ /job/$1/$2/jobshow_$3.html last;
将根目录下某个文件夹指向2级目录
如/shanghaijob/ 指向 /area/shanghai/
如果你将last改成permanent，那么浏览器地址栏显是/location/shanghai/
rewrite ^/([0-9a-z]+)job/(.*)$ /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 $request_filename) {
proxy_pass http://127.0.0.1;
}
域名跳转
server
{
listen80;
;
index index.html index.htm index.php;
root/opt/lampp/htdocs/www;
rewrite ^/ /;
access_logoff;
}
多域名转向
;
index index.html index.htm index.php;
root/opt/lampp/htdocs;
if ($host ~ "c1gstudio/.net") {
rewrite ^(.*) $1 permanent;
}
三级域名跳转
if ($http_host ~* "^(.*)/.i/.c1gstudio/.com$") {
rewrite ^(.*) $1;
break;
}
域名镜向
server
{
listen80;
;
index index.html index.htm index.php;
root/opt/lampp/htdocs/www;
rewrite ^/(.*) /$1 last;
access_logoff;
}
某个子目录作镜向
location ^~ /zhaopinhui {

break;

信赖此刻大部门用Linux VPS的伴侣都在利用这个敏捷传布的Nginx，本日就清算一下最常见的PHP法式的Rewrite(伪静态法则)。
Wordpress：
location / {
index index.html index.php;
if (-f $request_filename/index.html){
rewrite (.*) $1/index.html break;
}
if (-f $request_filename/index.php){
rewrite (.*) $1/index.php;
}
if (!-f $request_filename){
rewrite (.*) /index.php;
}
}
PHPCMS：
location / {
###以下为PHPCMS 伪静态化rewrite法则
rewrite ^(.*)show-([0-9]+)-([0-9]+)\.html$ $1/show.php?itemid=$2&page=$3;
