nginx 作为具有多个域和主机的反向代理

Question

这个问题可能已经被问过好几次了，但是考虑到我能找到的所有结果和我所知甚少，我有点迷失了。我使用的是 Fedora 29。

我尝试用 nginx 做什么：

• 使用一个让我们加密多个域名的 ssl 证书
• 将每个域映射到特定的内部主机（配置文件中的 DNS 或 IP，我不介意，无论什么都可以）
• 所有主机都已在内部使用 ssl（没有可用的 http - 多个侦听端口）
• 如果您从外部使用 http，我希望重定向到 https

样本 ：

• application.domain.com --> https://hostname1.domain.local（或 IP 1）

• test.domain.com --> https://hostname2.domain.local:1234（或 IP 2）

• www.domain.com --> https://hostname3.domain.local（或IP 3）等...

我怎样才能做到这一点？让我们加密自动配置我的 nginx 配置，但这似乎有点太多了。

非常感谢您的回答，我觉得我得到了一些进步，即使暂时没有工作。我在这里发布了我的完整配置文件，因为我现在遇到了“502 Bad Gateway”错误。IP 与反向代理不在同一子网中，但完全可访问，没有防火墙或路由问题。

知道我可以在哪里继续前进吗？在原始配置中，还有一个包含密码和协议的 certbot conf 文件。也许我需要重新包含它？

另外：我尝试访问的内部服务器具有使用我自己的 AD CS 签名的证书，但反向代理上尚未安装根证书。也许我应该 ？

为了让 NGINX 将多个域名解析为独立的代理，您需要为您正在使用的每个域设置一个服务器块（是的，您需要includeLE 提供的服务器块）：

server { listen 443 ssl; server_name application.domain.com; ssl on; ssl_certificate /etc/letsencrypt/live/www.domain.com/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/www.domain.com/privkey.pem; include /etc/letsencrypt/options-ssl-nginx.conf; location / { proxy_pass https://hostname1.domain.local:80/; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection 'upgrade'; proxy_set_header Host $host; proxy_cache_bypass $http_upgrade; } } server { listen 443 ssl; server_name test.domain.com; ssl on; ssl_certificate /etc/letsencrypt/live/www.domain.com/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/www.domain.com/privkey.pem; include /etc/letsencrypt/options-ssl-nginx.conf; location / { proxy_pass https://hostname3.domain.local:80/; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection 'upgrade'; proxy_set_header Host $host; proxy_cache_bypass $http_upgrade; } } server { listen 443 ssl; server_name www.domain.com; ssl on; ssl_certificate /etc/letsencrypt/live/www.domain.com/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/www.domain.com/privkey.pem; include /etc/letsencrypt/options-ssl-nginx.conf; location / { proxy_pass https://hostname2.domain.local:1234/; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection 'upgrade'; proxy_set_header Host $host; proxy_cache_bypass $http_upgrade; } }
