我正在尝试设置一台 Ubuntu 16.04 机器，以便 nginx-proxy 容器可以反向代理到 wordpress 容器。
我遇到的问题是，当尝试从外部世界访问该网站时，nginx 仅转发一些 GET 请求，即主页和网站图标的 HTML。它不会转发任何其他请求来加载页面的其他元素。
这是我的docker-compose.yml：
version: "2"
services:
mysql:
image: mysql:latest
container_name: db
restart: always
environment:
- MYSQL_ROOT_PASSWORD=SuperSecretMysqlPassword
volumes:
- /home/docker-stuff/var-lib-mysql:/var/lib/mysql
nginx-proxy:
image: jwilder/nginx-proxy:alpine
container_name: nginx
restart: always
ports:
- "443:443"
- "80:80"
volumes:
- /var/run/docker.sock:/tmp/docker.sock:ro
wordpress:
image: wordpress:latest
container_name: wp
restart: always
environment:
- VIRTUAL_HOST=example.com
- WORDPRESS_DB_HOST=mysql
- WORDPRESS_DB_USER=wordpress
- WORDPRESS_DB_PASSWORD=SuperSecretWordpressPassword
volumes:
- /home/wp/:/var/www/html/
docker-compose up这是我尝试访问该网站（在端口 80 上）时的输出：

我不太了解 nginx，所以我真的很感激这里的一些帮助......提前感谢！
答案1
经过大量的调试，我找到了这个问题的根本原因。我在这里详细说明一下，希望能对其他人有所帮助。
问题在于主页中的链接是根据主机的 IP 地址构建的，而不是主机名本身。这导致浏览器发出 GET 请求，其中“Host:”标头设置为 IP 地址而不是主机名，而 nginx 显然不知道如何处理它（然后请求由附加部分处理，其中server为nginx.tmpl所有请求发出 503 响应）。
为什么 wordpress 主页的链接中有这些 IP 地址？这可能是因为我最初安装 wordpress 时直接使用 IP 地址访问服务器，而当时 DNS 尚未启动并运行。我删除了 wordpress 数据库，然后通过主机名访问服务器重新安装，然后就好了！一切都很顺利！
由于某种原因，wordpress 会保存您用于访问它的主机名并使用它来构建其 html...
