Components: installing and offering software

For administrators

Components lists the server's services, runtimes such as PHP and Node.js, and tools such as phpMyAdmin. Software comes from the operating system's own packages.

One list

Every component the server offers is listed in its category, the installed ones first. An installed row shows its state with Start, Stop, Restart, Repair and start and Manage. A row that reads Not installed has Install, or says in one line why it cannot be installed here, for example Conflicts with Nginx beside Apache. Mail engines such as Postfix and Dovecot are installed with a mail setup at the top of the email category: their row says Install with a mail setup. DNS engines are chosen on the DNS page.

Every category is open on the first visit. Collapse all, Expand all or a category's own header folds and unfolds the categories; this browser remembers what you folded. Search finds any component. Rescan reads the server again, for example after you installed something yourself.

When another page says a component is missing, such as Fail2ban, ClamAV, vsftpd, Python, Node.js or WireGuard, its Install link opens that component's install window here. Nothing starts until you confirm.

Installing and removing

Install shows what the component needs before anything changes, under Requires: each requirement is Installed, installed together with it first, or missing with the reason and where it is done (mail engines come with a mail setup, for example). Missing parts that can be installed here, such as MariaDB and Nginx for phpMyAdmin, are installed first in the same operation; if one step fails, what was installed before it stays. phpMyAdmin, phpPgAdmin and Roundcube choose here the installed PHP version they run on. Package names are not listed; the window asks you to confirm only a change of repository, which it names (for example PostgreSQL (PGDG)).

Uninstall asks one question: what needs this component? The window answers in three groups:

  • Must be moved or removed first: sites, databases, mailboxes, apps, certificates, VPN peers, quarantined files, the panel firewall, or another component that is itself in use. Each one has a link to where you move or remove it. The removal is refused until the list is empty.
  • Will be removed together: small components that nothing else uses and that cannot work without it, such as phpPgAdmin with PostgreSQL. They are ticked; the server removes them first, then the component, as one operation that goes on even if you close the page. Unticking them means the component cannot be removed.
  • What stops: for example webmail when Roundcube goes. Mail keeps working.

Plans and accounts that offered the removed component or version lose that entry. Removing a database engine keeps its data.

Ready bundles install several components in a row, such as Core Mail or Nginx + PHP-FPM. A bundle with nothing installed yet says Install; one whose parts are partly here names what it adds, for example Add phpPgAdmin. If one step fails, Continue installs only what is still missing; nothing is removed.

Versions

PHP and Node.js keep several versions side by side; each site picks its own. Use Versions on the row to Install version or Remove version. If tools such as phpMyAdmin run on a version, the panel offers to move them first.

For PHP or PostgreSQL versions the system does not ship, the vendor's repository can be added for that component alone with Enable with its confinement and updates. Turning it off later removes nothing.

Offering software

Installing gives nothing to anyone. A customer can use a version or program only when you offer it and their plan includes it:

  • Offered to customers on the PHP and Node.js pages: tick each version. Hiding one changes no running site.
  • Users, tab Offered: every permission, program and application. See Plans and rights.

There is no separate developer toolbox yet; developers use the PHP and Node.js versions and SSH where their plan includes it.

When something is wrong

A stopped service shows on its row and under Needs attention on the dashboard. Repair and start tries to repair and start it. A failed install or change says what was tried and what is in place now.
