Creating a WordPress install
mkdir wp-trt cd wp-trt/ wp core download wp core config --dbname=wp-trt --dbuser=root wp db create wp core install --url=http://localhost:6789 --title=WPTRT --admin_user=danny --admin_password=blastworth --firstname.lastname@example.org nohup php -S localhost:6789 &* I was getting an error recently with a fresh install of mysql from homebrew, saying a database connection can not be established, during the `wp core install` step. After creating the symlinks as shown here, it worked.
