nginx设置404页码不生效、指定域名跨域的设置

一、404页面配置后不能生效的问题

1.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;

2.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

3.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;

4.想着模拟一次生产环境,进行验证
a.拷贝 生产的 /data/www/vhosts/film.chinasoft.jp 目录到yunweitools中
b.配置vhost.d和rewrite.d的配置,问题依旧说明不是nginx版本的问题
c.于是拷贝正常跳转的一个配置进行修改,问题解决
d.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 ;


问题描述:访问 https://itube.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

index

404.html改为

404

,避免页面内部问题,发现问题依旧,排除页面问题
3.修改vhost/itube.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

        error_log       /data/www/logs/nginx_log/error/itube.chinasoft.com_error.log ;
        root            /data/www/vhosts/itube.chinasoft.com/httpdocs ;

        #        }
        #    error_page  404 403             /404.html;
        #}

}

二、跳转设置

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;

返回1

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


三、nginx的配置指定域名可以跨域
map $http_origin $corsHost {
    default 0;
    "~http://www.123admin.com" http://www.123admin.com;
    "~http://m.123admin.com" http://m.123admin.com;
}

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

server
{
    listen 80;
    server_name search.123admin.com;
    root /nginx;
    location /
    {
        add_header Access-Control-Allow-Origin $corsHost;
    }
}
