How do I become a server admin?

If your server already has an admin account you should use the [User Admin API](../../admin_api/user_admin_api.md#change-whether-a-user-is-a-server-administrator-or-not) to promote other accounts to become admins.

---
Synapse includes a Python command to export data for a specific user. It takes the homeserver
configuration file and the full Matrix ID of the user to export:
```console
python -m synapse.app.admin_cmd -c <config_file> export-data <user_id>
python -m synapse.app.admin_cmd -c <config_file> export-data <user_id> --output-directory <directory_path>
```
If you uses [Poetry](../../development/dependencies.md#managing-dependencies-with-poetry)
to run Synapse:
```console
poetry run python -m synapse.app.admin_cmd -c <config_file> export-data <user_id> --output-directory <directory_path>
```
The directory to store the export data in can be customised with the
`--output-directory` parameter; ensure that the provided directory is
empty. If this parameter is not provided, Synapse defaults to creating
a temporary directory (which starts with "synapse-exfiltrate") in `/tmp`,
`/var/tmp`, or `/usr/tmp`, in that order.
The exported data has the following layout:
```
output-directory
├───rooms
│ └───<room_id>
│ ├───events
│ ├───state
│ ├───invite_state
│ └───knock_state
└───user_data
├───connections
├───devices
└───profile

Deleting your database is unlikely to make anything better.
It's easy to make the mistake of thinking that you can start again from a clean slate by dropping your database, but things don't work like that in a federated network: lots of other servers have information about your server.

Come and seek help in https://matrix.to/#/#synapse:matrix.org.
There are two exceptions when it might be sensible to delete your database and start again:
* You have *never* joined any rooms which are federated with other servers. For instance, a local deployment which the outside world can't talk to.
* You are changing the `server_name` in the homeserver configuration. In effect this makes your server a completely new one from the point of view of the network, so in this case it makes sense to start with a clean database.
