在反向代理 (lxd) 后面迁移现有的 worpress 站点

Question

我想放置一个带有 nginx 的代理容器来处理我的其他带有 wordpress 站点的容器的流量。

我目前正在使用以下设置：

Internet <--> webservices.lxd（将端口 80 && 443 添加到容器）<--> example.com (apache2)

新设置应如下所示：

Internet <--> proxy.lxd（将端口 80 && 443 添加到容器）(nginx) <--> webservices.lxd <--> example.com (apache2)

简而言之：我想放置一个反向代理容器来处理 lxd 容器之间的所有流量。

这是 nginx 反向代理配置文件：

server {

    server_name example.com;

location / {
                include /etc/nginx/proxy_params;
                proxy_pass http://webservices.lxd;
        }

        real_ip_header proxy_protocol;
        set_real_ip_from 127.0.0.1;


listen [::]:443 ssl proxy_protocol; # managed by Certbot
listen 443 ssl proxy_protocol; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}
server {
if ($host = example.com) {
    return 301 https://$host$request_uri;
} # managed by Certbot


    listen 80 proxy_protocol;
    listen [::]:80 proxy_protocol;

    server_name example.com;
return 404; # managed by Certbot

}

这是来自（当前无代理）Web 服务容器中的 apache2 站点配置：

root@webservices:/etc/apache2/sites-available# cat example.com.at-le-ssl.conf 
   <IfModule mod_ssl.c>
   <VirtualHost *:443>
     DocumentRoot "/var/www/example.com/htdocs"
     ServerName example.com
     UseCanonicalName On
# Security Section
     Header always set Strict-Transport-Security "max-age=63072000; includeSubDomains"
# Security Section Ende
 
 <Directory "/var/www/example.com/htdocs/">
     Options MultiViews FollowSymlinks
     AllowOverride All
     Order allow,deny
     Allow from all
</Directory>

TransferLog /var/log/apache2/example.com_access.log
ErrorLog /var/log/apache2/example.com_error.log


Include /etc/letsencrypt/options-ssl-apache.conf
ServerAlias www.example.com
SSLCertificateFile /etc/letsencrypt/live/example.com/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/example.com/privkey.pem
</VirtualHost>
</IfModule>
<IfModule mod_ssl.c>
<VirtualHost *:80>
ServerName example.com
ServerAlias *example.com

<Location "/">
        Redirect permanent "https://%{HTTP_HOST}%{REQUEST_URI}"
</Location>


</VirtualHost>
</IfModule>

我的问题是：

A. 我需要更改哪些内容才能运行新的代理设置？

B. 我是否需要更改其他内容（wordpress wp-config.php 或其他）？

C。 此外：数据库服务器也在 webservices 容器中运行。 我还应该为数据库制作一个新容器吗？
