VeravalOnline Failover Post Sync with DNS and IP

外掛說明

VeravalOnline Failover Post Sync with DNS and IP keeps a primary WordPress site and a standby copy in sync. Use it when the same public site runs on Server A and a failover Server B. Publishing on A used to leave B stale, which hurts SEO after DNS failover.

Install the plugin on both WordPress copies. The primary pushes:

  • Post title, slug, content, excerpt, status, and exact publish/modified dates
  • Featured images and attached media, written to the same uploads path
  • Categories, tags, and custom taxonomies
  • SEO and custom field metadata (Yoast, Rank Math, ACF, and others)
  • Deletes or trash, if enabled

Visitor-facing URLs stay on the public domain. The plugin never rewrites content to the failover IP or internal hostname.

DNS mode: Destination URL is a hostname that already points at Server B (internal DNS, hosts file, or a dedicated failover name).

IP mode: Destination URL is the public HTTPS URL. Destination IP is Server B. Requests keep the real Host/SNI so the SSL certificate still validates.

安裝方式

  1. Copy the veravalonline-failover-post-sync folder into wp-content/plugins/ on Server A and Server B.
  2. Activate VeravalOnline Failover Post Sync with DNS and IP on both sites.
  3. On both sites, open Failover Post Sync Settings and paste the same Shared API key.
  4. Server A: role = Primary. Set Destination URL to Server B’s WordPress home URL.
  5. Server B: role = Failover.
  6. On Server A click Test connection, then Sync all posts once to seed B.

常見問題集

Will this change permalinks or image URLs?

No. Slugs and upload relative paths are copied as-is. Public URLs stay on the visitor domain.

Do post IDs stay the same?

Not necessarily. Matching uses a hidden sync GUID, then the same slug. Gutenberg image IDs and attachment meta are remapped automatically.

What if we already created some posts by hand on Server B?

A full sync updates the failover post that has the same slug, so you do not get duplicates.

This plugin has been incredibly helpful for our multi-server failover setup. It perfectly synchronizes all post-related content across the board. It automatically handles the posts and their metadata, including URLs and featured images, so everything stays identical. It completely eliminates the need to manually duplicate posts.
