# Server configuration

The LXD server can be configured through a set of key/value configuration options.

The key/value configuration is namespaced.
The following options are available:

- {ref}`server-options-core`
- {ref}`server-options-acme`
- {ref}`server-options-oidc`
- {ref}`server-options-cluster`
- {ref}`server-options-images`
- {ref}`server-options-loki`
- {ref}`server-options-misc`

See {ref}`server-configure` for instructions on how to set the configuration options.

```{note}
Options marked with a `global` scope are immediately applied to all cluster members.
Options with a `local` scope must be set on a per-member basis.
