群晖不更改系统nginx 80端口 取消访问自动重定向至5000端口教程

使用群晖访问ip或自定义域名时群晖默认会将80端口重定向向至5000或其他自定DSM端口:

访问  http://192.168.123.228/ -> http://192.168.123.228:5000/

由于群晖系统nginx配置优先级问题当使用  synology 应用程序门户  反向代理   自定义子域名时会出现以下问题：

访问 http://blog.gofancy.top/  ->  http://blog.gofancy.top:5000/

nginx 会将子域名重定向到DSM端口

下面是取消将80端口重定向至DSM端口方法:

1.开启 ssh

2 win+R  CMD 打开终端 使用 ssh 登录

ssh gofancy@ip

切换到root

sudo -i

3 修改nginx 模板文件 

群晖会在重启后重置nginx配置 所以直接修改etc/nginx 配置是无效的 

进入nginx模板文件目录：

cd /usr/syno/share/nginx/

编辑模板文件

vim WWWService.mustache

将相关重定向配置注释掉

#location ~ ^/$ {
  #   rewrite / http://$host:{{DSM.port}}/ redirect;
#}

#location ~ ^/$ {
   #   rewrite / https://$host:{{DSM.ssl.port}}/ redirect;
#}

文件最后看起来是这样的

server {
    listen 80 default_server{{#reuseport}} reuseport{{/reuseport}};
    listen [::]:80 default_server{{#reuseport}} reuseport{{/reuseport}};

    gzip on;

    {{> /usr/syno/share/nginx/WWW_Main}}

    #location ~ ^/$ {
    #   rewrite / http://$host:{{DSM.port}}/ redirect;
    #}
}

server {
    listen 443 default_server ssl{{#reuseport}} reuseport{{/reuseport}};
    listen [::]:443 default_server ssl{{#reuseport}} reuseport{{/reuseport}};
    {{#DSM.https.compression}}
    gzip on;
    {{/DSM.https.compression}}

    {{> /usr/syno/share/nginx/WWW_Main}}

    #location ~ ^/$ {
    #   rewrite / https://$host:{{DSM.ssl.port}}/ redirect;
    #}
}

:wq 保存 

编辑文件

vim WWW_Main.mustache

注释相关配置

#location / {
#    rewrite ^ / redirect;
#}

最后看起开是这样的：

server_name _;

{{> /usr/syno/share/nginx/X-Accel}}

include app.d/www.*.conf;
include app.d/alias.*.conf;
include /usr/syno/share/nginx/conf.d/www.*.conf;
include conf.d/www.*.conf;

{{! package disable page's logo}}
location = /webdefault/images/logo.jpg {
    alias /usr/syno/share/nginx/logo.jpg;
}

{{> /usr/syno/share/nginx/error_page}}
{{> /usr/syno/share/nginx/LetsEncrypt}}
{{! for webstation super location block}}
{{! should be placed at the end of this server block}}
{{! but before redirect 80 to 5000 location}}
include app.d/.location.webstation.conf*;

#location / {
#    rewrite ^ / redirect;
#}

:wq 保存

重启群晖 

可以看到 /etc/nginx/nginx.conf 关于80端口和443端口配置已经发生变化：

 server {
        listen 80 default_server;
        listen [::]:80 default_server;

        gzip on;

        server_name _;

        location ~ ^/volume(?:X|USB|SATA|Gluster)?\d+/ {
            internal;

            root /;

            open_file_cache off;

            include app.d/x-accel.*.conf;
            include conf.d/x-accel.*.conf;
        }

        include app.d/www.*.conf;
        include app.d/alias.*.conf;
        include /usr/syno/share/nginx/conf.d/www.*.conf;
        include conf.d/www.*.conf;

        location = /webdefault/images/logo.jpg {
            alias /usr/syno/share/nginx/logo.jpg;
        }

        error_page 403 404 500 502 503 504 @error_page;

        location @error_page {
            root /usr/syno/share/nginx;
            rewrite (.*) /error.html break;
            allow all;
        }

        location ^~ /.well-known/acme-challenge {
            root /var/lib/letsencrypt;
            default_type text/plain;
        }

        include app.d/.location.webstation.conf*;

        #location / {
        #    rewrite ^ / redirect;
        #}

        #location ~ ^/$ {
        #   rewrite / http://$host:8080/ redirect;
        #}
    }

server {
        listen 443 default_server ssl;
        listen [::]:443 default_server ssl;

        server_name _;

        location ~ ^/volume(?:X|USB|SATA|Gluster)?\d+/ {
            internal;

            root /;

            open_file_cache off;

            include app.d/x-accel.*.conf;
            include conf.d/x-accel.*.conf;
        }

        include app.d/www.*.conf;
        include app.d/alias.*.conf;
        include /usr/syno/share/nginx/conf.d/www.*.conf;
        include conf.d/www.*.conf;

        location = /webdefault/images/logo.jpg {
            alias /usr/syno/share/nginx/logo.jpg;
        }

        error_page 403 404 500 502 503 504 @error_page;

        location @error_page {
            root /usr/syno/share/nginx;
            rewrite (.*) /error.html break;
            allow all;
        }

        location ^~ /.well-known/acme-challenge {
            root /var/lib/letsencrypt;
            default_type text/plain;
        }

        include app.d/.location.webstation.conf*;

        #location / {
        #    rewrite ^ / redirect;
        #}

        #location ~ ^/$ {
        #   rewrite / https://$host:4430/ redirect;
        #}
    }

这时访问群晖ip或域名 nginx 就不会自动做重定向了向5000做跳转了

如果想使用ip或域名直接访问可以在 synology 应用程序门户 反向代理  中手动添加一条记录指向DSM端口就可以了

如果修改了域名指向

最后记得刷新DNS本地缓存
