伪静态是一种可以把文件后缀改成任何可能的一种方法，如果我想把php文件伪静态成html文件，这种相当简单的，下面来介绍nginx 伪静态配置方法有需要了解的朋友可参考。

nginx里使用伪静态是直接在nginx.conf 中写规则的，并不需要像apache要开启写模块(mod_rewrite)才能进行伪静态。

nginx只需要打开nginx.conf配置文件，在server里面写需要的规则即可。

server 
{ 
listen       80; 
server_name  bbs.jb51.net; 
index index.html index.htm index.php; 
root  /home/www/bbs;
error_page  404                                             /404.htm;       #配置404错误页面 
location ~ .*.(php|php5)?$ 
{ 
#fastcgi_pass  unix:/tmp/php-cgi.sock; 
fastcgi_pass  127.0.0.1:9000; 
fastcgi_index index.php; 
include fcgi.conf; 
}
#下面就是伪静态了
location /{ 
rewrite ^(.*)/equip(d+).html$ $1/index.php?m=content&c=index&a=lists&catid=$2 last; 
} 
access_log  access_log   off; 
}

Copy after login

然后重启nginx服务器伪静态就生效了，这种维护起来很是不方便我们可以把它写在外部文件如bbs_nginx.conf中

在/home/www/bbs目录下创建bbs_nginx.conf文件并写入以下代码：

ocation /{ 
rewrite ^(.*)/equip(d+).html$ $1/index.php?m=content&c=index&a=lists&catid=$2 last; 
}

Copy after login

然后在上面的代码后面加上如下代码：

1	`include` `/home/www/bbs/bbs_nginx.conf;`

Copy after login

这样网站根目录中的bbs_nginx.conf伪静态规则，即可实现单独管理。

下面是一个实例：

1. 在使用.htaccess文件的目录下新建一个.htaccess文件，如下面一个Discuz论坛目录：

1	`vim /var/www/html/jb51/bbs/.htaccess`

Copy after login

2. 在里面输入规则，我这里输入Discuz的伪静态规则（这里仅增加Discuz的伪静态规则）：

# nginx rewrite  rule 
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; 
# end nginx rewrite rule

Copy after login

wq保存退出。

3. 修改nginx配置文件：

1	`vim /etc/nginx/nginx.conf`

Copy after login

4. 在需要添加伪静态的虚拟主机的server{}中引入.htaccess文件：

1	`include` `/var/www/html/jb51/bbs/.htaccess; （备注：把路径改成你.htaccess文件的具体位置）`

Copy after login

wq保存退出。

5. 重新加载nginx配置文件：

1	`/etc/init.d/nginx reload`

Copy after login

Nginx常用Rewrite伪静态规则：

伪静态规则是我们做伪静态的一个非常重的参数了，如果我们能理解得越多就可以快速的写出最优的伪静态代码了，下面给大家整理了一些例子，希望能给你有帮助。

本日志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

Copy after login

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;

Copy after login

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;
}

Copy after login

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;
}

Copy after login

目录自动加“/”

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

Copy after login

禁止htaccess

location ~//.ht {
deny all;
}

Copy after login

禁止多个目录

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

Copy after login

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;
}

Copy after login

禁止单个目录
不能禁止.log.txt能请求

location /searchword/cron/ {
deny all;
}

Copy after login

禁止单个文件

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

Copy after login

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;
}

Copy after login

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;
}

Copy after login

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://www.php.cn/;”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 *.jb51.net *.jbzj.net localhost 1.1.1.1;
if ($invalid_referer) {
rewrite ^/ http://www.php.cn/;
return 412;
break;
}
access_log off;
root /opt/lampp/htdocs/web;
expires 3d;
break;
}

Copy after login

只允许固定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;

Copy after login

将多级目录下的文件转成一个文件，增强seo效果

1 2	`/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;`

Copy after login

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;`

Copy after login

上面例子有个问题是访问/shanghai 时将不会匹配

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

Copy after login

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;
}

Copy after login

知道原因后就好办了，让我手动跳转吧

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

Copy after login

文件和目录不存在的时候重定向：

if (!-e $request_filename) {
proxy_pass http://www.php.cn/;
}

listen 80;
server_name jump.c1gstudio.com;
index index.html index.htm index.php;
root /opt/lampp/htdocs/www;
rewrite ^/ http://www.php.cn/;
access_log off;
}

Copy after login

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”) {

Explain different error types in PHP (Notice, Warning, Fatal Error, Parse Error). Apr 08, 2025 am 12:03 AM

There are four main error types in PHP: 1.Notice: the slightest, will not interrupt the program, such as accessing undefined variables; 2. Warning: serious than Notice, will not terminate the program, such as containing no files; 3. FatalError: the most serious, will terminate the program, such as calling no function; 4. ParseError: syntax error, will prevent the program from being executed, such as forgetting to add the end tag.

PHP and Python: Comparing Two Popular Programming Languages Apr 14, 2025 am 12:13 AM

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP in Action: Real-World Examples and Applications Apr 14, 2025 am 12:19 AM

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Apr 17, 2025 am 12:06 AM

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

What are HTTP request methods (GET, POST, PUT, DELETE, etc.) and when should each be used? Apr 09, 2025 am 12:09 AM

HTTP request methods include GET, POST, PUT and DELETE, which are used to obtain, submit, update and delete resources respectively. 1. The GET method is used to obtain resources and is suitable for read operations. 2. The POST method is used to submit data and is often used to create new resources. 3. The PUT method is used to update resources and is suitable for complete updates. 4. The DELETE method is used to delete resources and is suitable for deletion operations.
