原文外掛簡介
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.
