Grommunio

Grommunio は、デジタル通信とコラボレーションソフトウェアスイートです。それは異なるコンポーネントのセットから構築されます。

このガイドは、動作するセットアップを得るために異なるコンポーネントの基本的なインストールと設定をガイドします。

それは、初期スタートをかなり難しくしたいくつかのギャップを埋めようとし、どのコンポーネントが他のものと一緒に動作しているかを説明します。

インストール

この章では、必要なパッケージの基本的なインストールをガイドします。何を達成したいか、そしてどのようにそこに到達するかについての大まかな概要を提供します。

概要

単一ノードサーバーを持ちたいと想定しています。そのサーバーが必要なすべてのコンポーネントをホストします。

これには、サーバーに mta のセットアップがあり、設定されていること (例: [postfix])、そしてさらに動作する mysql データベースがあること (例: [mariadb]) を想定しています。

オプションで、ディレクトリサーバー ([OpenLDAP|openldap] または [samba|ActiveDirectory]) が利用可能であるべきです。このガイドに従うためには必要ありませんが、完全なイメージを得るためには非常に推奨されます。

パッケージ

これは、インストールが必要な grommunio パッケージのリストです：

Configuration

This chapter will guide through the initial configuration to get everything up and running.

It is highly recommended to read / follow the official guide along which is the basis for all the tasks that are following.

General information

There will be multiple system user accounts created and used that will separate the needed permissions regarding their needs.

This will be described in more detail during this guide, but for now the following explanation should give a rough overview.

Users / Groups

Name	Type	Description
grommunio	User	Administration API user
gromox	User	Service user for the core services
gromoxcf	Group	Group that can read core config files
gromoxss	Group	Group that can access shared resources (in this case zcore socket)

There are more users / groups used by single services to separate and limit the access to the minimum needed ones. Further some users (like http used by nginx) will be added to some groups to be able to access the needed resources (ae. php-fpm sockets).

Database

The first step is to create a database and a user for grommunio and adjust the configuration file. Therefore connect to your database and create a db and user for your setup. The following example is using mariadb as backend.

$ mariadb -u root -p
$ CREATE DATABASE `grommuniodb`;
$ GRANT ALL ON `grommuniodb`.* TO 'grommunio'@'localhost' IDENTIFIED BY 'super-secrect-password';
$ FLUSH PRIVILEGES;
$ quit;

After creating the user, we'll edit the file mysql_adaptor.cfg from the gromox package and change the values to our db ones.

$ vim /etc/gromox/mysql_adaptor.cfg

mysql_username=grommunio
mysql_password=super-secret-password
mysql_dbname=grommuniodb
schema_upgrade=host:your.mailserver.dom

The schema_upgrade is not required for a single node setup. It is only needed to have one master updating database schema and tell the nodes which one is in charge.

The next step is to create the initial tables by issuing the gromox-dbop command:

$ gromox-dbop -C
dbop: Creating admin_roles
dbop: Creating associations
dbop: Creating configs
dbop: Creating domains
dbop: Creating forwards
dbop: Creating groups
dbop: Creating options
dbop: Creating orgs
dbop: Creating specifieds
dbop: Creating users
dbop: Creating aliases
dbop: Creating mlists
dbop: Creating user_properties
dbop: Creating admin_role_permission_relation
dbop: Creating admin_user_role_relation
dbop: Creating classes
dbop: Creating fetchmail
dbop: Creating secondary_store_hints
dbop: Creating user_devices
dbop: Creating user_device_history
dbop: Creating task_queue
dbop: Creating servers
dbop: Creating orgparam
dbop: Creating altnames

event / timer

gromox-event is a notification daemon for an interprocess channel between gromox-imap/gromox-midb. The config file is '/etc/gromox/timer.cfg' and just contains the state path adopted to my setup:

timer_state_path=/var/lib/grommunio/gromox/timer.txt

gromox-timer is an at(1)/atd(8)-like daemon for delayed delivery. There is no explicit configuration delivered for this service.

The timer service listens on port 6666 and the event service on port 33333.

For all possible configuration directives you can refer to their man pages: event and timer

Now we enable and start these services:

$ systemctl enable --now gromox-event
$ systemctl enable --now gromox-timer
