Citadel is a powerful and easy-to-use email and collaboration suite that can run on various platforms, including Alpine Linux. In this tutorial, we'll show you how to install and set up Citadel on Alpine Linux Latest.
Before we begin, make sure that you have the following:
To run Citadel on Alpine Linux, we need to install some dependencies first. Open a terminal and run the following command:
sudo apk add gcc make libc-dev automake autoconf libtool db-dev gnutls-dev postgresql-dev openssl-dev libsieve-dev icu-dev
Next, we need to download and install Citadel. Go to the Citadel website and download the latest stable release. In this tutorial, we'll be using version 9.01.
wget https://github.com/citadel/citadel/releases/download/9.01/citadel-9.01.tar.gz
tar zxvf citadel-9.01.tar.gz
cd citadel-9.01
./configure --enable-unicode --with-cyrus-sasl --with-plugindir=/usr/lib/citadel-server/plugins
make
sudo make install
Citadel uses PostgreSQL as its database backend. If you don't already have it installed, you can do so by running:
sudo apk add postgresql
sudo rc-service postgresql start
sudo su - postgres
psql
Once you're in the PostgreSQL command line interface, create a new user and database for Citadel.
CREATE USER citadel WITH PASSWORD 'password';
CREATE DATABASE citadel WITH OWNER=citadel;
Exit the PostgreSQL interface and switch back to your regular user account.
\q
exit
Now, it's time to configure Citadel. Let's create a new configuration file.
sudo cp /usr/local/citadel/citadel.conf.example /usr/local/citadel/citadel.conf
sudo nano /usr/local/citadel/citadel.conf
In the configuration file, you'll need to modify some settings. Here's a sample configuration file:
LogFileName = /var/log/citadel.log
SysconfDirectory = /usr/local/citadel
DataDirectory = /usr/local/citadel/data
PkgDataDirectory = /usr/local/citadel/data
DatabaseUserName = citadel
DatabaseName = citadel
ImapPort = 993
WebCitPort = 80
FullHostname = your.domain.com
Save the configuration file and exit.
Finally, let's start Citadel and test if it's working properly.
sudo mkdir /var/log/citadel
sudo chown -R citadel:citadel /var/log/citadel
sudo rc-service citadel start
Open up a web browser and enter your server's IP address or hostname followed by port 2000, for example, http://your.domain.com:2000/. You should see the Citadel login page. Log in with the default username admin and password password.
Congratulations! You've successfully installed and set up Citadel on Alpine Linux Latest.
