WordPress

Tundra provides first-class WordPress support via the tundrad-plugin-wordpress plugin, which uses WP-CLI for all lifecycle operations.

Installing WordPress

1. Create a new site and select WordPress as the source.
2. Choose PHP version (8.2+ recommended).
3. Enter the primary domain.
4. Complete the 3-step install wizard:
   • Step 1: Site title, admin username, admin email
   • Step 2: Database settings (auto-generated credentials)
   • Step 3: Confirm and install

Tundra runs the full WP-CLI provisioning sequence:

• Creates a dedicated MySQL database and user
• Installs WordPress core via wp core download + wp core install
• Configures wp-config.php with encrypted credentials
• Sets up wp-cron as a proper systemd timer

WordPress detail tabs

Tab	What’s here
Overview	Version, PHP, disk usage, SSL status, last backup
Plugins	Install/activate/deactivate/delete via WP.org search
Themes	Install/activate/delete via WP.org search
Users	WordPress user list, role management
PHP	PHP version picker with searchable combobox
Database	Connection details, password rotation, phpMyAdmin SQL editor
Security	File editing toggle, security checklist
Backups	Site-scoped snapshots
Danger	Delete installation, reset admin password

Plugin & theme management

Search WordPress.org directly from the panel:

Plugins → Search WP.org → install → activate

Tundra runs WP-CLI commands on the server:

• wp plugin install {slug} --activate
• wp theme install {slug} --activate
• wp plugin update --all

PHP version management

Change PHP version without downtime:

1. Go to WordPress → [install] → PHP
2. Select a new version from the searchable picker
3. Tundra reconfigures the PHP-FPM pool and reloads Caddy

Database tools

The built-in SQL editor (phpMyAdmin-style) supports:

• Syntax-highlighted SQL (CodeMirror, MySQL dialect)
• Dark and light mode
• Query results in a scrollable table
• Connection details with masked password + reveal button
• One-click password rotation (generates new credentials, updates wp-config.php)

Staging and cloning

Create staging

1. Go to WordPress → [install] → Overview
2. Click Create staging
3. Tundra: DB dump → file copy → new credentials → GUID rewrite → new domain

Clone to new site

1. Click Clone
2. Enter the destination domain
3. Tundra performs the same pipeline to a new site

Promote staging to production

1. On the staging install, click Promote to production
2. Confirm — Tundra swaps the databases and file trees atomically

Caution

Promoting staging to production replaces the production database. Back up first in Backups.

Per-install database isolation

Each WordPress install gets its own MySQL database and user:

Database: wp_site123_production
User:     wp_site123_usr
Password: (auto-generated, encrypted at rest)

No WordPress install shares credentials with another, limiting blast radius if one is compromised.
