# Making Multiple Mopidy Instances



This script/instruction detials how to create multiple instances of mopidy which pipe their outputs to separate mopidy streams. 



This enables you to have the flexibility to play one song across multiple speakers or have each speaker play its own song. 



### Prerequistes 



* Mopidy installed [Mopidy Github](https://github.com/mopidy/mopidy)

* Snapcast installed [Snapcast Github](https://github.com/badaix/snapcast)



## Automatically



```

$ wget https://github.com/ESteanes/Mopidy_Multiple-Instances/releases/download/v0.1.0/multiple_mopidy.sh

$ bash multiple_mopidy.sh -N  -H  -O snapcast

```

Note: leaving the hostname blank will result in 127.0.0.1 which means that mopidy will only listen to local requests. Generally unfavourable setup.

## Manually



\ represents the number of instances



1. Create additional mopidy_\.conf files

```

$ sudo touch /etc/mopidy/mopidy_.conf

```

2. Using a text editor, edit the file you created and add the following information in your mopidy_\.conf

```

[core]

cache_dir = /var/cache/mopidy_

data_dir = /var/lib/mopidy_



[http]

port = 668



[audio]

output = audioresample ! audioconvert ! audio/x-raw,rate=48000,channels=2,format=S16LE ! filesink location=/tmp/snapfifo_

```

3. _Optional_ Adding custom settings



You may want to add custom information such as spotify accounts to different mopidy instances as that can help with personalisation. Do that in the corresponding file



For example spotify settings:

```

[spotify]

enabled = true

username = [email protected]

password = your_spotify_password

client_id = your_client_id

client_secret = your_client_secret

```



4. Modify the original mopidy.conf file



Add in all the allowed origins for however many mopidy instances you created. This will allow you to access your 2nd mopidy 

```

$ nano /etc/mopidy/mopidy.conf



allowed_origins = :6680,:668 (for all n)

```

5. Create and give ownership of cache and data directoires



If creating multiple directories, can use * wildcard for `chown` command

```

$ mkdir /var/cache/mopidy_

$ mkdir /var/lib/mopidy_

$ chown mopidy:audio /var/cache/mopidy_ /var/lib/mopidy_

```

6. Create copies of the mopidyctl script



Creating copies of the mopidyctl script will enable you to run these mopidy instances as a service without having to manually enable them upon reboot.



```

$ cp /usr/sbin/mopidyctl /usr/sbin/mopidyctl_

```

Then inside `usr/sbin/mopidyctl_`, change the `CONFIG_FILES` variable to the following:

```

CONFIG_FILES="/usr/share/mopidy/conf.d:/etc/mopidy/mopidy.conf:/etc/mopidy/mopidy_.conf"

```

This will make sure that the service will utilise the appropriate configuration files

unique to the extra instances, overwriting that in the base `mopidy.conf` file with the details in `mopidy_.conf` that you altered previously.



7. Creating additional systemd scripts



You need to create copies of the systemd scripts to activate systemd for all the different instances



```

$ cp /lib/systemd/system/mopidy.service /lib/systemd/system/mopidy_.service

```

Then, using a text editor, edit the `mopidy_.service` file with the following:

```

ExecStart=/usr/bin/mopidy --config /usr/share/mopidy/conf.d:/etc/mopidy/mopidy.conf:/etc/mopidy/mopidy_.conf

```

8. Adding additional streams to Snapcast



Since we are creating multiple instances of mopidy, we need to add these filesink locations in the snapcast configuration file that we are referencing in section 2.



```

$ nano /etc/snapserver.conf

```

then under the `[Stream]` heading, add the following:

```

source = pipe:///tmp/snapfifo_?name=

```

Here you can specify a custom name for each source. You can set up each of the mopidy instances for different people or sections of your house/apartment.



9. Restart all the services



Restart all the services and complete the initialising processes

```

$ systemctl restart snapserver.service

$ mopidyctl_ local scan

$ systemctl enable mopidy*.service

$ systemctl start mopidy*.service
