详情介绍:

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: 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.

安装:

  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.

常见问题:

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.
