# How to configure the LXD server

See {ref}`server` for all configuration options that are available for the LXD server.

If the LXD server is part of a cluster, some of the options apply to the cluster, while others apply only to the local server, thus the cluster member.
In the {ref}`server` option tables, options that apply to the cluster are marked with a `global` scope, while options that apply to the local server are marked with a `local` scope.

## Configure server options

````{tabs}
```{group-tab} CLI
You can configure a server option with the following command:

    lxc config set <key> <value>

For example, to allow remote access to the LXD server on port 8443, enter the following command:

    lxc config set core.https_address :8443

In a cluster setup, to configure a server option for a cluster member only, add the `--target` flag.
For example, to configure where to store image tarballs on a specific cluster member, enter a command similar to the following:

    lxc config set storage.images_volume my-pool/my-volume --target member02
```
```{group-tab} API
Send a PATCH request to the `/1.0` endpoint to update one or more server options:

    lxc query --request PATCH /1.0 --data '{
      "config": {
        "<key>": "<value>",
        "<key>": "<value>"
      }
    }'

For example, to allow remote access to the LXD server on port 8443, send the following request:

    lxc query --request PATCH /1.0 --data '{
      "config": {
        "core.https_address": ":8443"
      }
    }'

In a cluster setup, to configure a server option for a cluster member only, add the `target` parameter to the query.
For example, to configure where to store image tarballs on a specific cluster member, send a request similar to the following:

    lxc query --request PATCH /1.0?target=member02 --data '{
      "config": {
        "storage.images_volume": "my-pool/my-volume"
      }
    }'

See [`PATCH /1.0`](swagger:/server/server_patch) for more information.
```
```{group-tab} UI
Go to {guilabel}`Settings` to configure the server options.

In a cluster setup, server options that apply to the local server are updated only for the server on which you are accessing the UI.
For example, if you access the UI on `server1` and update the location for storing image tarballs ({config:option}`server-miscellaneous:storage.images_volume`, which has a `local` scope) from `local/pool1` to `local/pool2`, `storage.images_volume` will still be configured to `local/pool1` on `server2`.
```
````

## Display the server configuration

````{tabs}
```{group-tab} CLI
To display the current server configuration, enter the following command:

    lxc config show

In a cluster setup, to show the local configuration for a specific cluster member, add the `--target` flag.
```
```{group-tab} API
Send a GET request to the `/1.0` endpoint to display the current server environment and configuration:

    lxc query --request GET /1.0

In a cluster setup, to show the local environment and configuration for a specific cluster member, add the `target` parameter to the query:

    lxc query --request GET /1.0?target=<cluster_member>

See [`GET /1.0`](swagger:/server/server_get) for more information.
```
```{group-tab} UI
Go to {guilabel}`Settings` to view the current server configuration.

In a cluster setup, this view shows the local configuration for the cluster member on which you are accessing the UI.
```
````

## Edit the full server configuration

````{tabs}
```{group-tab} CLI
To edit the full server configuration as a YAML file, enter the following command:

    lxc config edit

In a cluster setup, to edit the local configuration for a specific cluster member, add the `--target` flag.
```
```{group-tab} API
To update the full server configuration, send a PUT request to the `/1.0` endpoint:

    lxc query --request PUT /1.0 --data '<server_configuration>'

In a cluster setup, to update the full server configuration for a specific cluster member, add the `target` parameter to the query:

    lxc query --request PUT /1.0?target=<cluster_member> '<server_configuration>'

See [`PUT /1.0`](swagger:/server/server_put) for more information.
```
```{group-tab} UI
The UI does not currently support editing the full server configuration.
