Web server stacks

nginx is always the public edge of a node; choose one of four chains behind it, and the panel switches and rolls back if the change fails.

What it is

Only one process can own ports 80 and 443, so there is one edge per node, and it is always nginx. The chain behind it is chosen per node: nginx alone (PHP-FPM), nginx+Apache, nginx+Varnish or nginx+Varnish+Apache. Everything behind it (PHP-FPM, containers) listens on loopback.

What it is for

Moving a node from nginx+Apache to nginx+Varnish, for example, without hand-editing vhosts: the panel regenerates the configuration for every site.

Limits

Switching releases the ports, rewrites the PHP sockets and brings up the new edge; if it does not come up the panel returns to the previous edge. Apache alone and OpenLiteSpeed alone are not offered: a node that had either is moved to nginx+Apache on update.
