Создать каталог /etc/prosody/conf.d для хранения пользовательских конфигураций:

# mkdir -p /etc/prosody/conf.d

В конец файла /etc/prosody/prosody.cfg.lua дописать строку:

Include "conf.d/*.cfg.lua"

Создать конфигурационный файл prosody для вашего домена (например, /etc/prosody/conf.d/jitsi2.test.alt.cfg.lua) со следующим содержимым:

plugin_paths = { "/usr/share/jitsi-meet/prosody-plugins/" }

Сгенерировать сертификаты для виртуальных хостов jitsi2.test.alt и auth.jitsi2.test.alt:

# prosodyctl cert generate jitsi2.test.alt
# prosodyctl cert generate auth.jitsi2.test.alt

Зарегистрировать сертификаты в системе, как доверенные (сертификаты нужно регистрировать там, где устанавливается Jicofo):

# ln -s /var/lib/prosody/jitsi2.test.alt.crt /etc/pki/ca-trust/source/anchors/
# ln -s /var/lib/prosody/auth.jitsi2.test.alt.crt /etc/pki/ca-trust/source/anchors/
# update-ca-trust

Зарегистрировать пользователя focus (аккаунт focus@auth.jitsi2.test.alt):

# prosodyctl register focus auth.jitsi2.test.alt secret2

где secret2 — достаточно длинный пароль.

Запустить prosody:

# prosodyctl start
