   [--force]                    Overwrites existing files, if present. 

wp core download

Voorbeeld van gedownloade WordPress-instanties als zip-bestanden

download een actuele WordPress-instantie en plaats die uitgepakt en MD5-geverifiëerd in de werkmap, of in de map die wordt meegegeven. In tegenstelling tot Drupal, werkt dit heel simpel.

wp core download

   [--path=<path>]         Specify the path in which to install WordPress. Defaults to current directory.
   [--locale=<locale>]     Select which language you want to download.
   [--version=<version>]   Select which version you want to download. Accepts a version number, ‘latest’ or ‘nightly’
   [--force]               Overwrites existing files, if present. 

Voorbeeld:

$ cd /var/www/example.com

$ wp core download

Downloading WordPress 5.9.1 (en_US)...
md5 hash verified: 5bbe205b48cf9255fd7c954040aeb125
Success: WordPress downloaded.

$ ls
index.php    wp-activate.php     wp-comments-post.php  wp-cron.php        wp-load.php   wp-settings.php   xmlrpc.php
license.txt  wp-admin            wp-config-sample.php  wp-includes        wp-login.php  wp-signup.php
readme.html  wp-blog-header.php  wp-content            wp-links-opml.php  wp-mail.php   wp-trackback.php

Wat-ie precies doet:

• De WordPress-instantie wordt gedownload als gezipped phar-archief naar /tmp. Zie afbeelding hiernaast
• md5-hash van dit archiefbestand wordt geverifiëerd
• Het archiefbestand wordt uitgepakt naar een tijdelijke locatie

Foutmelding: Couldn't decompress

Het probleem:

wp core download
Downloading WordPress 4.8.2 (en_US)...
md5 hash verified: 2e8744a702a3d9527782d9135a4c9544
Error: Couldn't extract WordPress archive. unable to decompress gzipped phar archive "/tmp/wp_59c276fb45c4b.tar.gz" to temporary file

Aanvullende gegevens:

• sudo chmod o+w /tmp - Hielp niet
• sudo /usr/local/bin/wp core download --allow-root - Hielp niet
• wp cli ge-update - Hielp niet

wp core install

Installeer een gedownloade WordPress-instantie:

$ wp help core install 

NAME

  wp core install

DESCRIPTION

  Runs the standard WordPress installation process.

SYNOPSIS

  wp core install --url=<url> --title=<site-title> --admin_user=<username> [--admin_password=<password>]
  --admin_email=<email> [--skip-email]

  Creates the WordPress tables in the database using the URL, title, and
  default admin user details provided. Performs the famous 5 minute install
  in seconds or less.

  Note: if you've installed WordPress in a subdirectory, then you'll need
  to `wp option update siteurl` after `wp core install`. For instance, if
  WordPress is installed in the `/wp` directory and your domain is example.com,
  then you'll need to run `wp option update siteurl http://example.com/wp` for
  your WordPress installation to function properly.

  Note: When using custom user tables (e.g. `CUSTOM_USER_TABLE`), the admin
  email and password are ignored if the user_login already exists. If the
  user_login doesn't exist, a new user will be created.

OPTIONS

  --url=<url>
    The address of the new site.

  --title=<site-title>
    The title of the new site.

  --admin_user=<username>
    The name of the admin user.

  [--admin_password=<password>]
    The password for the admin user. Defaults to randomly generated string.

  --admin_email=<email>
    The email address for the admin user.

  [--skip-email]
    Don't send an email notification to the new admin user.

EXAMPLES

    # Install WordPress in 5 seconds
    $ wp core install --url=example.com --title=Example --admin_user=supervisor --admin_password=strongpassword
    --admin_email=info@example.com
    Success: WordPress installed successfully.

    # Install WordPress without disclosing admin_password to bash history
    $ wp core install --url=example.com --title=Example --admin_user=supervisor --admin_email=info@example.com
    --prompt=admin_password < admin_password.txt

• Dit commando moet uitgevoerd worden in de working map waar de installatiebestanden staan, en waar de site geïnstalleerd moet worden
• Op mijn ontwikkelcomputer kreeg ik een foutmelding dat Sendmail niet gevonden kon worden. Ik weet niet of dat door het script komt, of een configuratiefout ergen op m'n computer.

Dit commando werkt alleen met een al gedownloade WordPress-instantie:

$ wp core install --url=example.com --title="Example.com"

Error: This does not seem to be a WordPress installation.
Pass --path=`path/to/wordpress` or run `wp core download`.

Compleet voorbeeld

Al deze commando's zijn noodzakelijk. Het werkt trouwens heel soepeltjes. Veel gemakkelijker dan downloaden enzo:

cd /var/www/example.com
wp core download
wp config create --dbname=example_com --dbuser=example_com --dbpass=example_123_EXAMPLEEEE
wp core install --url=example.com --title="Example.com" --admin_user="Jan Jansen" --admin_password="blubBLddddUB-123" --admin_email="info@example.com"

wp core update

Simpel:

wp core update

Plugins worden hierbij niet bijgewerkt.

wp core update-db

Geen idee waarom er een apart commando is om de db bij te werken. Eén keer gedaan na update van een site die al een tijdje niet was bijgewerkt: Geen verschil.
