       +
       This chapter will show you how to set up your own, self-hosted

     

       4
       +
       [Mjolnir](https://github.com/matrix-org/mjolnir) instance.

     

       5
       +
       

     

       6
       +
       As an all-in-one moderation tool, it can protect your server from

     

       7
       +
       malicious invites, spam messages, and whatever else you don't want.

     

       8
       +
       In addition to server-level protection, Mjolnir is great for communities

     

       9
       +
       wanting to protect their rooms without having to use their personal

     

       10
       +
       accounts for moderation.

     

       11
       +
       

     

       12
       +
       The bot by default includes support for bans, redactions, anti-spam,

     

       13
       +
       server ACLs, room directory changes, room alias transfers, account

     

       14
       +
       deactivation, room shutdown, and more.

     

       15
       +
       

     

       16
       +
       See the [README](https://github.com/matrix-org/mjolnir#readme)

     

       17
       +
       page and the [Moderator's guide](https://github.com/matrix-org/mjolnir/blob/main/docs/moderators.md)

     

       18
       +
       for additional instructions on how to setup and use Mjolnir.

     

       19
       +
       

     

       20
       +
       For [additional settings](#opt-services.mjolnir.settings)

     

       21
       +
       see [the default configuration](https://github.com/matrix-org/mjolnir/blob/main/config/default.yaml).

     

       22
       +

       +
       ## Mjolnir Setup {#module-services-mjolnir-setup}

     

       24
       +
       

     

       25
       +
       First create a new Room which will be used as a management room for Mjolnir. In

     

       26
       +
       this room, Mjolnir will log possible errors and debugging information. You'll

     

       27
       +
       need to set this Room-ID in [services.mjolnir.managementRoom](#opt-services.mjolnir.managementRoom).

     

       28
       +
       

     

       29
       +
       Next, create a new user for Mjolnir on your homeserver, if not present already.

     

       30
       +
       

     

       31
       +
       The Mjolnir Matrix user expects to be free of any rate limiting.

     

       32
       +
       See [Synapse #6286](https://github.com/matrix-org/synapse/issues/6286)

     

       33
       +
       for an example on how to achieve this.

     

       34
       +
       

     

       35
       +
       If you want Mjolnir to be able to deactivate users, move room aliases, shutdown rooms, etc.

     

       36
       +
       you'll need to make the Mjolnir user a Matrix server admin.

     

       37
       +
       

     

       38
       +
       Now invite the Mjolnir user to the management room.

     

       39
       +
       

     

       40
       +
       It is recommended to use [Pantalaimon](https://github.com/matrix-org/pantalaimon),

     

       41
       +
       so your management room can be encrypted. This also applies if you are looking to moderate an encrypted room.

     

       42
       +
       

     

       43
       +
       To enable the Pantalaimon E2E Proxy for mjolnir, enable

     

       44
       +
       [services.mjolnir.pantalaimon](#opt-services.mjolnir.pantalaimon.enable). This will

     

       45
       +
       autoconfigure a new Pantalaimon instance, which will connect to the homeserver

     

       46
       +
       set in [services.mjolnir.homeserverUrl](#opt-services.mjolnir.homeserverUrl) and Mjolnir itself

     

       47
       +
       will be configured to connect to the new Pantalaimon instance.

     

       48
       +
       

     

       49
       +
       ```

     

       50
       +
       {

     

       51
       +
         services.mjolnir = {

     

       52
       +
           enable = true;

     

       53
       +
           homeserverUrl = "https://matrix.domain.tld";

     

       54
       +
           pantalaimon = {

     

       55
       +
              enable = true;

     

       56
       +
              username = "mjolnir";

     

       57
       +
              passwordFile = "/run/secrets/mjolnir-password";

     

       58
       +
           };

     

       59
       +
           protectedRooms = [

     

       60
       +
             "https://matrix.to/#/!xxx:domain.tld"

     

       61
       +
           ];

     

       62
       +
           managementRoom = "!yyy:domain.tld";

     

       63
       +
         };

     

       64
       +
       }

     

       65
       +
       ```

     

       66
       +
       

     

       67

       ### Element Matrix Services (EMS) {#module-services-mjolnir-setup-ems}

     

       68
       +
       

     

       69
       +
       If you are using a managed ["Element Matrix Services (EMS)"](https://ems.element.io/)

     

       70
       +
       server, you will need to consent to the terms and conditions. Upon startup, an error

     

       71
       +
       log entry with a URL to the consent page will be generated.

       ## Synapse Antispam Module {#module-services-mjolnir-matrix-synapse-antispam}

     

       74
       +
       

     

       75
       +
       A Synapse module is also available to apply the same rulesets the bot

     

       76
       +
       uses across an entire homeserver.

     

       77
       +
       

     

       78
       +
       To use the Antispam Module, add `matrix-synapse-plugins.matrix-synapse-mjolnir-antispam`

     

       79
       +
       to the Synapse plugin list and enable the `mjolnir.Module` module.
