4. Data and WordPress
&
Configuration

5. CONFIGURATION MANAGEMENT
The task of tracking and controlling
changes in the software

6. DATA AND WORDPRESS
• Core, plugin and theme files
• Data stored in a MySQL db
• Options/Transients/Object Caching
• Media Library assets and files
• Configuration wp-config.php
WHAT DATA DOES WORDPRESS USE?

7. DATA AND WORDPRESS
“Configuration varies across deploys,
code stays the same”

8. DATA AND WORDPRESS
• Database
• Files
• Uploads
WHAT DATA IS NEEDED FOR DEPLOYMENT?

9. DATA AND WORDPRESS
• wp-config.php - keeps site specific configuration
• Different when using multiple dev environments
• Has sensitive information
CONFIGURATION

10. DATA AND WORDPRESS
• Some settings apply to all environments
• Each environment has unique settings
• Credentials will be different each environment
• Keep credentials out of version control
CONFIGURATION WITH MULTIPLE ENVIRONMENTS

11. DATA AND WORDPRESS
• Allows you to keep variations of your wp-config.php
• Each environment has it’s own unique config
• Uses variables to include proper configuration file

12. Sync Codebase

13. DEPLOYMENT
• SFTP/FTP
• Version Control - GIT, SVN
SYNC CODEBASE

14. DEPLOYMENT
• Version Control allows you to be sure that all changes are
pushed to environments
•Can ignore files and directories that are not needed
SYNC CODEBASE

15. Sync Uploads

16. DEPLOYMENT
• Typically not stored in version control
• Files can be large
• Will not change very much
UPLOADS DIRECTORY

17. DEPLOYMENT
• Copy all files
• Copy files you need
• Point to files on another server
SYNC UPLOADS METHODS

18. DEPLOYMENT
• FTP can be used to copy the entire uploads directory
• Can be done with client app
COPY ALL FILES

19. DEPLOYMENT
• rsync -avz --rsh=ssh user@host:/path/to/wp-content/uploads/* .
• Requires SSH some command line chops
• Not available on all hosting providers
COPY ALL FILES - RSYNC

20. DEPLOYMENT
• FTP can be used to copy only recent files
• WordPress organizes uploads by date if configured
COPY SOME FILES

//** Uploads by Proxy */
define('WP_SITEURL', 'http://edmund.local');
define('UBP_IS_LOCAL', true);
define('UBP_SITEURL', 'http://www.edmundturbin.com');

24. Database Migration

25. DATA IN WORDPRESS
• WP-CLI
• SFTP/FTP & mysql import
• 3rd party plugins
MOVE DATABASE EXPORT ACROSS ENVIRONMENTS

26. DATABASE MIGRATION
• WP-CLI
• MySQL import
• PHPMyAdmin
DATABASE IMPORT

27. DATABASE MIGRATION
• Allow you to run remote wp-cli commands
• Connects via SSH behind the scenes
• @dev, @stage, @production
• Uses a prefix before wp-cli command
• wp @dev cli info
WP-CLI ALIASES

28. DATABASE MIGRATION
• wp @production db export > production_db_export.sql
• wp @dev db reset —yes
•wp @dev db import production_db_export.sql
• wp @dev search-replace example.com example.dev

29. Configuration
Management

30. CONFIGURATION MANAGEMENT
• Save time by transferring only what we need
• Less data to be transferred
• Data does not need to be synced
WHAT IF WE ONLY NEED TO MAKE A FEW CHANGES?

31. CONFIGURATION MANAGEMENT
• Settings are unique - site_url, home_url
• Not all plugins are needed on production
• Site admins or user can make settings changes
WHAT IF SETTINGS ARE DIFFERENT IN EACH ENVIRONMENT?

32. PLUGIN: WP-CFM
https://wordpress.org/plugins/wp-cfm/

33. PLUGIN: WP-CFM
• Copy settings that you need, not entire DB
• Keep track of all settings in a single place
• Version Control
• Manage multiple environments
https://wordpress.org/plugins/wp-cfm/
BENEFITS

34. PLUGIN: WP-CFM
• Allows you to save options
• Can be saved as sets called Bundles
• Push changes to file
• Pull changes into database
https://wordpress.org/plugins/wp-cfm/
HOW DOES IT WORK?

35. PLUGIN: WP-CFM
• Data saved to disk as JSON array
• Can be committed to a repo
• Changes managed in WP Dashboard
• Permissions on settings?
https://wordpress.org/plugins/wp-cfm/
WORDPRESS CONFIGURATION MANAGEMENT

36. PLUGIN: WP-CFM
• WP settings (wp_options table)
• Multisite settings (wp_sitemeta table)
• Taxonomy terms
• Custom Field Suite field groups
https://wordpress.org/plugins/wp-cfm/
WHAT DATA CAN BE MANAGED?

37. PLUGIN: WP-CFM
wp config pull [bundle_name]
wp config push [bundle_name]
wp config diff [bundle_name]
wp config bundles
wp config show_bundle [bundle_name]

WP-CLI COMMANDS

38. Codebase & Uploads
Version control ensures your
codebase is synced. Uploads
pulled down regularly

39. WP-CLI for DB Sync
WP-CLI can make it simple to keep
your content in sync across
multiple environments

40. Configuration
Can differ across different tiers,
but can still be managed centrally
within codebase.
