nginx跳转规则的记录

1.首页跳转的示例：
if ($host ~* ^chinasoft.com$){ rewrite ^(.*)$ https://www.chinasoft.com$1 permanent;}
if ($request_uri ~ ^/(.*)/(index|indice).(html)) { rewrite ^/(.*)/(index|indice).(html) /$1   permanent;}
if ($request_uri ~ ^/(index|indice).html) { rewrite    ^       / permanent;}

2.跳转后去掉参数
https://mobiletrans.chinasoft.com/buy/?f=pro 跳转到 https://mobiletrans.chinasoft.com/buy/a.html

最终如下配置跳转到了 https://mobiletrans.chinasoft.com/buy/a.html?f=pro

if ($request_uri ~ ^/buy/?f=pro) { rewrite ^ https://mobiletrans.chinasoft.com/buy/a.html permanent; }
if ($request_uri ~ ^/buy/$) { rewrite ^ https://mobiletrans.chinasoft.com/buy/a.html permanent; }

# 加上?号，可以去掉 ? 后面的参数
if ($request_uri ~ ^/buy/?f=pro) { rewrite ^ https://mobiletrans.chinasoft.com/buy/a.html? permanent; }

3.多层目录下首页index.html跳转
默认的跳转规则：
[root@web02:/usr/local/nginx/conf/rewrite.d]# more film.chinasoft.com.conf
if ($request_uri ~ ^/(.*)/(index|indice).(html)) { rewrite ^/(.*)/(index|indice).(html) /$1   permanent;}

类似 index.html结尾的跳转，会跳转两次
https://film.chinasoft.com/screen-recorder-faq/installation/index.html

会跳到
https://film.chinasoft.com/screen-recorder-faq/installation

然后再次跳转到 https://film.chinasoft.com/screen-recorder-faq/installation/

修改后
# more film.chinasoft.com.conf
if ($request_uri ~ ^/(.*)/(index|indice).(html)) { rewrite ^/(.*)/(index|indice).(html) /$1/   permanent;}

https://film.chinasoft.com/screen-recorder-faq/installation/index.html 可以直接跳转到 https://film.chinasoft.com/screen-recorder-faq/installation/

部分地区不行
https://film.chinasoft.com/chinasoft-id-guide/index.html

4.404页面的跳转问题

a.配置了404页面，跳转不到根目录的404.html，即打开的错误页面不变，不发生301跳转就显示 /404.html
error_page 404 403            /404.html;

b.于是配置了 error_page 404 403            https://film.chinasoft.jp/404.html; 这样会导致大量的404发生301跳转，不利于seo优化

c.之前配置nginx.conf的主配置添加下面参数就可以了，该次不生效

proxy_intercept_errors on;
fastcgi_intercept_errors on;

d.想着模拟一次生产环境，进行验证
①.拷贝生产的 /data/www/vhosts/film.chinasoft.jp 目录到yunweitools中
②.配置vhost.d和rewrite.d的配置，问题依旧说明不是nginx版本的问题
③.于是拷贝正常跳转的一个配置进行修改，问题解决
④.于是diff对比之前的配置和现在正常的配置，发现没有大的区别 httpsdocs 多了一个s，这才是问题的关键

root            /data/www/vhosts/film.chinasoft.jp/httpdocs ; 是 root            /data/www/vhosts/film.chinasoft.jp/httpsdocs ;

5.多个网站需要设置跨域的配置
map $http_origin $corsHost {
    default 0;
    "~http://www.chinasoft.com" http://www.chinasoft.com；
    "~http://m.chinasoft.com" http://m.chinasoft.com;
}

https://shopcart.chinasoft.com,https://film.chinasoft.com'

server
{
    listen 80;
    server_name search.chinasoft.com;
    root /nginx;
    location /
    {
        add_header Access-Control-Allow-Origin $corsHost;
    }
}

6.404页面跳转不生效的问题处理

[/usr/local/nginx/conf/vhost.d]# cat film.chinasoft.jp.conf

问题描述：访问 https://stu.chinasoft.com/aaaa/bbbb/ 类似这种不存在的页面返回首页，访问各种不存在的页面都返回首页，测试了很多种方法不行

后面出了狠招，直接将环境移植到一台可以测试的服务器中（可以任意测试，没有风险）
可能出现的问题：
1.整体的nginx环境问题
2.nginx配置问题
3.页面有隐性跳转

具体步骤：
1.部署好nginx和php移植后台程序到测试服务器，本地绑定hosts，发现问题依旧，排除服务器环境问题
2.将首页改为 <h1>index</h1> 404.html改为 <h1>404</h1>，避免页面内部问题，发现问题依旧，排除页面问题
3.修改vhost/stu.chinasoft.com文件，将php部分注释掉发现问题没有了
定位到是php部分的配置问题

        }

}

film.chinasoft.jp.conf配置
# 404配置，访问不存在的页面不生效
error_page 404 403              /404.html;

# https://film.chinasoft.jp/404.html 页面存在
于是修改
error_page 404 403              https://film.chinasoft.jp/404.html;

8.修改默认首页
页面地址：
https://recoverit.chinasoft.com/support/refund-and-renewal-faqs.html

点击里面的链接会跳到

http://support.chinasoft.com/&_ga=2.1314520.1688688#/article?id=1710

返回1

加入：
location / {
       try_files $uri $uri/ /index.html;
   }

需求：
原URL地址                           跳至地址
https://www.chinasoft.cc/conn/convert-3gp-to-flv.html   https://www.chinasoft.cc/

访问https://www.chinasoft.cc/conn/convert-3gp-to-flv.html会自动跳转到主页：
分析：
1.可能是cdn缓存，发现这个站点没有用cdn排除
2.跳转规则有问题，发现没有这样的跳转规则，这个站点除了默认的跳转规则没有做任何跳转
3.将 /data/www/vhosts/httpds/conn/ 目录下的 convert-3gp-to-flv.html 文件备份，改成输出ok
(本地指一台机器作为chinasoft.cc的机器)发现没有跳转，替换成原来的就跳转
说明没有这个url的跳转规则，所以规则来自页面内的js或者html需要开发定位修改

1.vhost.d规则限制了跳转
原地址                           取消跳转至
https://videoconn.chinasoft.com/fr/convert-mp4/   https://videoconn.chinasoft.com

发现rewrite里面没有这个规则，是因为设置了

error_page 404 403        https://videoconn.chinasoft.com ;

当碰到404的时候跳转到首页

2.当设置一个目录跳转时，目录下的子页面也全部跳转了

# 跳转设置
if ($request_uri ~ ^/download/) { rewrite ^ https://stu.chinasoft.com/downloads/ permanent; }
if ($request_uri ~ ^/download/2.html) { rewrite ^ https://stu.chinasoft.com/downloads/ permanent; }
if ($request_uri ~ ^/download/3.html) { rewrite ^ https://stu.chinasoft.com/downloads/ permanent; }

发生了问题
故障1
访问 https://stu.chinasoft.com/download/download-high-school.html 跳转到了https://stu.chinasoft.com/downloads/

分析：
当设置了目录跳转 ^/download/ 开头的页面全部到 https://stu.chinasoft.com/downloads/会导致 download目录下的页面全部跳转到   https://stu.chinasoft.com/downloads/

解决：添加限定符号$，只匹配一个页面
if ($request_uri ~ ^/download/$) { rewrite ^ https://stu.chinasoft.com/downloads/ permanent; }

故障2
当访问 https://stu.chinasoft.com/download/ 出现404

当用f12时发现访问 https://stu.chinasoft.com/download 出现403 forbidden
解决办法
chmod 755 /data/www/vhosts/stu.chinasoft.com/httpdocs/download
