Joomla Manager

Install and manage Joomla sites in an existing domain, via Joomla's own CLI installer — deliberately simpler than the WordPress Manager: no dedicated Joomla Manager sidebar page, no cloning, no filesystem scan for existing installs, no hardening rules, and no dedicated backup system. Install, a read-only overview with live status, cache clearing, one-time admin login, error logs, and uninstall.

Install Joomla​

Navigate to OpenPanel > AutoInstaller and click Install Joomla.

On the install page, configure:

• Domain – The domain (and optional subfolder) to install into. Leave the subfolder blank to install at the domain root.
• Site name – Displayed as the site's title.
• Joomla version – Latest, or pin to a specific release, fetched live from Joomla's GitHub releases.
• Admin full name / username / password / email – The initial Super User account Joomla creates during install. Leave the password blank to generate one.

Behind the scenes, this downloads the matching Joomla_<version>-Stable-Full_Package.tar.gz release archive, extracts it into the docroot, creates a dedicated MySQL/MariaDB database, and runs Joomla's own installation/joomla.php install CLI installer with the details you provided. Progress is streamed live as each step completes.

Manage a Joomla site​

Every Joomla install shows up on the general Site Manager page (/sites) alongside your other websites. Click Manage on a Joomla site to open its overview page:

• Screenshot and Joomla / PHP / MariaDB / Created status cards, matching the other CMS managers.
• Files – Docroot path, a File Manager shortcut, and live folder size.
• Database – Host, name, table prefix, and password (read live from configuration.php, not stored anywhere separately), plus a phpMyAdmin shortcut.
• PHP version – Editable for root-level installs; subdirectory installs inherit the domain's PHP version.

Login as Admin​

The Login as Admin button generates a one-time login link and opens the Joomla administrator dashboard already authenticated, without needing the admin password. Joomla core has no built-in CLI command for this (unlike Drupal's drush user:login), so OpenPanel deploys a small login helper file into the docroot at install time; each click issues a fresh token valid for 10 minutes and usable once.

Cache​

The Cache widget runs Joomla's own cli/joomla.php cache:clean, clearing the system cache.

Logs​

The Logs tab shows the contents of administrator/logs/*.php — the PHP warnings/errors Joomla logs by default. A freshly installed, healthy site typically has none yet.

Remove​

The Remove tab's Delete Application button fully uninstalls the site: drops the database and database user, deletes every file in the docroot, and removes it from Site Manager. This cannot be undone.

Not included​

To keep this feature simple, the following are not part of Joomla support (unlike the WordPress Manager):

• A dedicated "Joomla Manager" sidebar page — manage installed sites from Site Manager instead
• Cloning a site
• Scanning the filesystem for untracked installations
• Security hardening rules
• A dedicated backup/restore system (use the account-level Backups feature instead)
• Only MySQL/MariaDB databases are supported (not PostgreSQL)
