Nginx Nextcloud 重定向过多

我正在尝试在我的 Raspberry Pi 上安装 Nextcloud。

  1. 我在 Cloudflare 中创建了一个A record子域，指向我的 Raspberry Pi IP 地址，并NGINX使用certbot中的默认配置文件进行了配置/etc/nginx/sites-available/nextcloud。
    1. 我已经创建了符号链接/etc/nginx/sites-enables并检查了NGINX配置，sudo nginx -t并且配置全部有效。
    2. 我已成功重定向到，但当我尝试在浏览器中https打开时，出现错误，提示重定向太多。nextcloud.mydomain.com

这是我的nextcloud配置：

upstream php-handler {
    server 127.0.0.1:9000;
    #server unix:/var/run/php/php7.3-fpm.sock;
}

    server_name nextcloud.domain.com;

    if ($host = nextcloud.domain.com) {

    } # managed by Certbot

我已将我的域名替换为domain。

/var/log/nginx/access.log我收到了很多带有重定向和 HTTP 代码的行：301 和 185 。

如果我删除重定向return 301 https://$server_name:443@request_uri;行，我仍然会被重定向到https，但我不知道为什么。

顺便说一下，我以前曾lighttpd在 Raspberry Pi 上安装过，但在安装之前我已经将其卸载了NGINX。

答案1

server您对和都有一个定义HTTP，并且HTTPS正如您所注意到的，有以下几行：

if ($host = nextcloud.domain.com) {
    return 301 https://$server_name:443$request_uri;
} # managed by Certbot

造成最大的损害。由于这是301重定向，您的浏览器会记住它，直到重新启动。

拆分两个监听端口的配置，使得第一行是：

server {
    listen 80;
    server_name nextcloud.domain.com;

    return 301 https://$server_name$request_uri; # managed by Certbot
}

server {
    listen 443 ssl http2;
    server_name nextcloud.domain.com;
    # rest of the config

编辑：正如您所说，您可以将两个listen指令放在一个server块中，但这会导致重定向循环如果您的服务器是使用 直接访问的nextcloud.domain.com。Cloudflare 可能会在您的客户端和nginx并使用您的 IP 而不是域名转发请求。因此循环仍然隐藏，但它仍然存在。

如果您想保留单个服务器块，您应该考虑将条件更改if为：

if ($scheme = http) {
    return 301 https://$server_name$request_uri;
} # managed by Certbot

不过从清晰度和性能上来说，可能比两块还差server。
