Wordpress多站点Nginx重定向循环

Question

我确信这只是一个基本的配置。我有一个wordpress多站点正在运行，带有基本域。我想实现简单的域映射，不幸的是，nginx-config的Wordpress文档非常缺乏。

9个月前，我尝试并成功地使用WU域映射插件做到了这一点，但这一次它不起作用，我宁愿让它在没有插件的情况下工作(旨在安装低插件WP(。

当然，我已经修改了网站部分的网站URL来测试这一点。

我目前拥有的是：

site1.com (working)
site2.site1.com (working)
site2.com (301 redirect loop)

我想要的是：

site1.com
site2.com

有什么建议需要添加到我的Nginx conf文件中吗？我当前的nginx conf文件与Digital Ocean Docker设置页面的文件基本相同：

server {
listen 80;
listen [::]:80;

server_name *.site1.com site1.com www.site1.com;
location ~ /.well-known/acme-challenge {
allow all;
root /var/www/html;
}
location / {
rewrite ^ https://$host$request_uri? permanent;
}

error_log    /var/log/nginx/error.log;
access_log  /var/log/nginx/access.log;
}
server {
error_log    /var/log/nginx/error.log;
access_log  /var/log/nginx/access.log;
listen 443 ssl http2;
listen [::]:443 ssl http2;
server_name site1.com www.site1.com;
index index.php index.html index.htm;

location / {
try_files $uri $uri/ /index.php$is_args$args;
}
location ~ .php$ {
try_files $uri =404;
fastcgi_split_path_info ^(.+.php)(/.+)$;
fastcgi_pass wordpress:9000;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
}
location ~ /.ht {
deny all;
}
location = /favicon.ico {
log_not_found off; access_log off;
}
location = /robots.txt {
log_not_found off; access_log off; allow all;
}
location ~* .(css|gif|ico|jpeg|jpg|js|png)$ {

log_not_found off;
}
}

如果我登录并运行nginx命令，请检查nginx Docker，我会收到以下错误消息：编辑-这也发生在工作配置上，所以我猜这可能是转移注意力

在容器中，netstat为端口80/443提供了以下信息：

tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      1/nginx: master pro

在集装箱外，它似乎只正确运行了一个端口：

tcp        0      0 0.0.0.0:443             0.0.0.0:*               LISTEN      1298/docker-proxy
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      1313/docker-proxy

编辑(18/3/21(：

刚刚从另一个IP地址的工作备份中进行了恢复，但我对这个特定的域仍然有问题。有趣的是，我跨越了另一个不同域的网站，这个网站正在工作！

我会检查配置，看看里面是否有什么不同，如果没有，我想我需要走DNS路线，检查它是否正确地针对我的主机。

天哪，那真是一场胡言乱语。经过几天的努力，它变成了Cloudflare SSL。今天确实注意到了，但没有注意到。

事情指向DNS/SSL，但不确定它可能是什么。在这里找到了Cloudflare SSL设置的参考，在网站的SSL/TLS设置中，我将加密模式设置为灵活，它们应该是完整。设置它，它现在就工作了。我觉得我已经解决了这个问题，这次最好把它记得更清楚！
