Install WordPress on shared hosting
The control panel can create the database and the WordPress files together. You still choose the site title and the admin password yourself.
Log in to DirectAdmin after the account exists. The installer creates a database and the WordPress files. Pick the directory on purpose: the domain root if this name should be the site, or a subfolder if you are only testing.
Choose the admin username yourself. Do not reuse the account password. Turn on updates for small releases, and take a panel backup before the first major upgrade. Basic allows one website. If this is a second install, you need Professional or Unlimited.
Permalinks, the site title and the discussion settings are yours. The host does not log in and write them. If the installer stops, the usual cause is a database quota. Basic includes two databases.
Caching in Mumbai can hide a change for a few minutes. Use the clear-cache control after you edit. Carts and logins are not served from that cache.
