Docker Nginx + 多个域 + 1 vps 中各自目录上的多个 WordPress

Question

目前，我想在 1 个 vps 中运行多个具有多个域的 WordPress 站点。我希望我可以将每个 WordPress 放在单独的子文件夹中。

我尝试了很多不同的方法，但第一次访问设置 WordPress 时总是出现 404 错误。

这是我在 nginx error.log 中的错误日志

*6 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 192.168.63.1, server: site1.com, request: "GET / HTTP/1.0", upstream: "fastcgi://172.21.0.4:9000", host: "192.168.63.130"

谁能向我解释我做错了什么？谢谢你！

也许它会对某人有所帮助。我使用单个 Nginx docker 成功部署了多个（域）WordPress docker 容器。

docker-compose.yml：

version: '3'

services:
  db:
    image: mysql:8.0
    container_name: db
    restart: unless-stopped
    env_file: .env
    environment:

    environment:
      - WORDPRESS_DB_HOST=db:3306

    location / {

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass wordpress:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME /var/www/html$fastcgi_script_name;

    location ~* \.(css|gif|ico|jpeg|jpg|js|png)$ {
        expires max;
        log_not_found off;
    }
}

我花了几个小时甚至几天的时间来弄清楚我需要改变：

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

到

fastcgi_param SCRIPT_FILENAME /var/www/html$fastcgi_script_name;

希望我能为任何人腾出一些额外的时间。
