wordpressでHTTPS化するためにリバースプロキシをNginxで構築する

• Nginx側の設定 "https://myblog.ms" でHTTPS化すると仮定しています。
  

server {
    root /var/www/html;

    # Add index.php to the list if you are using PHP
    index index.html index.htm index.nginx-debian.html;
        server_name myblog.ms; # managed by Certbot
        proxy_set_header    Host    $host;
        proxy_set_header    X-Real-IP    $remote_addr;
        proxy_set_header    X-Forwarded-Proto https;
        proxy_set_header    X-Forwarded-Port 443;
        proxy_set_header    X-Forwarded-Host       $host;
        proxy_set_header    X-Forwarded-Server    $host;
        proxy_set_header    X-Forwarded-For    $proxy_add_x_forwarded_for;

    location / {
                proxy_pass http://172.18.100.2;
                #ご自身のwordpressのサーバーのIPアドレスを記入してください
    }

    listen [::]:443 ssl ipv6only=on; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/myblog.ms/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/myblog.ms/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 ($host = myblog.ms) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    listen 80 ;
    listen [::]:80 ;
    server_name myblog.ms;
    return 404; # managed by Certbot


}

• wordpress側の設定 wp-config.php

<?php
$_SERVER['HTTP_HOST'] = $_SERVER['HTTP_X_FORWARDED_HOST'];
$_SERVER['REMOTE_ADDR'] = $_SERVER['HTTP_X_FORWARDED_FOR'];
define('FORCE_SSL_ADMIN',true);
$_SERVER['HTTPS'] = 'on';
define('WP_HOME','https://myblog.ms');
define('WP_SITEURL','https://myblog.ms');
