WordPress URLs point actual server behind NGINX

NGINX did not translate URL correctly

When accessing server via NGINX, it didn't translate URLs in page to the URL accessing.

For example, the URL is https://example.com/sample.html, the server behind is https://192.168.1.11/sample.html, the NGINX is still leaving it without translating.

I have done following, but not useful

1. Updated both options siteurl and home in database

update wp_options set option_value='http://newhost:8080' where option_name='siteurl';
update wp_options set option_value='http://newhost:8080' where option_name='home';

2. Added host and port in wp_config.php

if (isset($_SERVER['HTTP_X_FORWARDED_HOST'])) {
      $_SERVER['HTTP_HOST'] = $_SERVER['HTTP_X_FORWARDED_HOST'];
}

if (isset($_SERVER['HTTP_X_FORWARDED_HOST'])) {
      $_SERVER['HTTP_HOST'] = $_SERVER['HTTP_X_FORWARDED_PORT'];
}

Someone suggested following lines as well, but I didn't do it.

define('WP_HOME','https://test.com/blog/');
define('WP_SITEURL','https://test.com/blog/');

3. Updated NGINX configuration.

proxy_pass http://newhost

Solution

Modify NGINX configuration

Configure https

server {
    server_name  blog.bianxi.com;

    # SSL configuration
    listen 443 ssl;

    ssl_certificate     conf.d/www.bianxi.com.crt;
    ssl_certificate_key conf.d/www.bianxi.com.key;

    location / {
        proxy_pass      'http://192.168.1.14:8080';
        proxy_http_version 1.1;
        proxy_buffering off;
        proxy_read_timeout    90;
        proxy_connect_timeout 90;
        proxy_redirect        off;
        proxy_set_header Host $host;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-Proto https;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Port 443;
        proxy_set_header Proxy "";
    }
}

Configure http redirect

server {
    listen       80;
    server_name  blog.bianxi.com;

    return 301 https://$host$request_uri;
}

Config wp-config.php

Add following lines in wp-config.php

//$_SERVER['REQUEST_URI'] = str_replace("/wp-admin/", "/blog/wp-admin/",  $_SERVER['REQUEST_URI']);

if($_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https'){

    $_SERVER['HTTPS'] = 'on';
    $_SERVER['SERVER_PORT'] = 443;

    define('WP_HOME','https://blog.bianxi.com/');
    define('WP_SITEURL','https://blog.bianxi.com/');
}

If change URL is required

Change location in NGINX configuration file, and the URL replace were used if requires changing of URL as well in wp-config.php file.
