Upgrade WordPress hosts to PHP 8

[Krinkle]

The wp hosts are currently on PHP 5. More specifically, PHP 5.4, which has been EOL since 2014.

A safer option might be PHP 5.6, which has support for another year. On the other hand, there have been very few breaking changes and WordPress themselves currently recommend PHP 7.2. Seems worth trying to upgrade there in one step.

Quote from https://github.com/jquery/infrastructure/issues/312:

As part of the infra refresh we will (for now) continue to use WordPress for the foreseeable future. (ref jquery/infrastructure-puppet#8, jquery/infrastructure#449, and subtask for WordPress: jquery/infrastructure-puppet#6)

Notable changes:

• Public infrastructure as code: https://github.com/jquery/infrastructure-puppet
• Latest Debian, PHP, MySQL, and WordPress.
• Few or no plugins. Simple standalone theme.
• No multi-site network. Simple standalone WP installations.

Since last month, the stage.* sites for all doc sites under .jquery.com, .jquery.org, .jqueryui.com, and, .jquerymobile.com have been provisioned and switched over in DNS to wp-02.stage which runs WordPress 6 and PHP 7.4. E.g. https://stage.jquery.com and https://stage.api.jquery.com, which are open for testing.

The first batch of production sites has been switched over as well:

• wp-04:
  • https://learn.jquery.com
• wp-05:
  • https://jquery.org
  • https://meetings.jquery.org
  • https://jquerymobile.com
  • https://api.jquerymobile.com

Next batch is rolled out.

wp-04:

• https://releases.jquery.com (also switched to Fastly as of this week, code.jq not yet)

wp-05:

• https://brand.jquery.org/
• https://contribute.jquery.org/

Next batch is rolled out to the new infra with PHP 8, WordPress 6, on Debian 12 Bookworm.

wp-04:

• https://jquery.com
• https://api.jquery.com

wp-05:

• https://jqueryui.com
• https://api.jqueryui.com

Changes of note:

• jquery.com: Remove unused build-member-list task for corporate-members.json. https://github.com/jquery/jquery.com/commit/48306399824e2cbfff9a884a863789a493010ecf and https://github.com/jquery/jquery-wp-content/commit/c0ea32e850cb72cfeda1de4fdf145fd51b0524ba
• jqueryui.com: move site-specific plugin into theme functions. https://github.com/jquery/jquery-wp-content/commit/c0ea32e850cb72cfeda1de4fdf145fd51b0524ba

Left on old infrastructure:

• wp-01:
  • https://plugins.jquery.com
• wp-02: (nothing)
• wp-03: (nothing)

TODO:

• Omit tarsnap for staging hosts such as wp-02.stage.ops.jquery.net (not needed).
• Recreate the wp stage host on Debian 12 with PHP 8.2 rather than Debian 11 with PHP 7.4.

I've created wp-03.stage.ops.jquery.net as placeholder for the new droplet to replace wp-02.stage

[Krinkle]

I've decommisioned wp-02.ops and wp-03.ops.

• Backups remotely deleted from Tarsnap.
• Droplet deleted from DO.
• DNS entries removed from CF.
• Provision removed from old Puppet repo (private).

wp-03.ops was originally created 23 October 2014 and ran Debian 7, nginx 1.10.3, PHP 5.4.45-1~dotdeb+7.1.

wp-01.ops is still pending archiving of plugins.jquery.com at https://github.com/jquery/infrastructure-puppet/issues/29.

wp-02.stage is now decomissioned as well, that brings all WordPress sites to new infra and running PHP 8.
