Tenho um boletim informativo sub-pilha com um registro CNAME apontando paranewsletter.identosphere.net
Quero que esse conteúdo seja exibido identosphere.net/newsletterpara que o usuário possa acessar cada boletim informativo como parte do meu site principal:
identosphere.net/newsletter/issue-13/deve exibir conteúdo denewsletter.identosphere.net/issue-13/
Além disso,se possível(seja por nginx ou DNS)Quero redirecionar o tráfego do subdomínio para sua pasta no domínio raiz.
No momento estou usando:
location /newsletter/ {
proxy_pass http://newsletter.identosphere.net/;
access_log /var/log/nginx/reverse-access.log;
error_log /var/log/nginx/reverse-error.log;
}
O que acontece com esta configuração:
Eu digitohttps://identosfera.net/newslettere sou redirecionado parahttps://newsletter.identosphere.net/
Conforme solicitado por@ppuschmann, estou postando o resto da minha configuração do nginx.
O que não mencionei é que estou usandoMailInABoxé um serviço de e-mail auto-hospedado que inclui um servidor web e DNS.
Principalmente, as personalizações são feitas via GUI. Estou usando um recurso não suportado que permite alguma personalização da sua configuração, mas não da configuração principal, que é atualizada regularmente. Aparentemente, não consigo adicionar blocos de servidor à minha "configuração do usuário nginx", apenas blocos de localização.
Neste ponto, não espero resolver isso, mas, se possível, gostaria de determinar como o DNS (NSD) o redirecionamento está definido, impedindo meu proxy reverso.
Aqui está a configuração do NGINX
Conforme declarado nos comentários, não posso editar este arquivo, mas posso adicionar instruções por meio de uma configuração localizada em outro lugar.

Responder1
Você precisa pelo menos definir:
proxy_set_header Host newsletter.identosphere.net;
Isso envia o cabeçalho correto Hostpara o servidor upstream, que pode estar configurado para enviar redirecionamentos quando houver um Hostcabeçalho incorreto na solicitação.
Responder2
Você poderia usar um bloco de servidor dentro da configuração do Nginx e, em seguida, usar o proxy reverso. Permite até um redirecionamento de porta, o que é simplesmente fantástico.
Aqui está um trecho sobre um site ativo, do meu arquivo de configuração em /etc/nginx/sites-available/default:
server {
server_name wows-karma.com www.wows-karma.com;
location / {
proxy_pass http://localhost:5021;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection keep-alive;
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
server {
server_name api.wows-karma.com;
location / {
proxy_pass http://localhost:5020/api/;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection keep-alive;
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
Este exemplo (que, a propósito, é um site real, ativo e funcional) deve ser material suficiente para cobrir seu caso de uso. Sugiro que você siga o exemplo da API e adapte-o às suas necessidades.
Ah, e também, o Proxy Reverso também funciona em destinos remotos, não apenas locais. Pense nas possibilidades...
