IMP is a webmail client that is part of the Horde project, a free and open-source groupware application suite that includes email, calendars, contacts, and more. In this tutorial, we will show you how to install IMP on Alpine Linux Latest.
Before installing IMP, we need to ensure that the package repository is up to date. We can do this by running the following command:
sudo apk update
IMP requires a web server to run, and Apache is a popular option. To install Apache, run the following command:
sudo apk add apache2
After the installation, start the Apache service and enable it to start automatically at system boot:
sudo rc-service apache2 start
sudo rc-update add apache2
Verify that the Apache web server is running by accessing http://localhost on your web browser.
IMP is written in PHP, so we need to install PHP and the required extensions. Run the following command to install PHP and the required extensions:
sudo apk add php7-apache2 php7-json php7-iconv php7-session php7-dom php7-xml php7-xmlreader php7-xmlwriter
After installation, restart the Apache web server:
sudo rc-service apache2 restart
IMP requires a database to store its data. If you do not have a database management system already installed, you can choose either MySQL or MariaDB. To install it, run the following command:
sudo apk add mariadb mariadb-client
After the installation, start and enable the MySQL service:
sudo rc-service mariadb start
sudo rc-update add mariadb
Secure the MySQL installation by running the following command:
sudo mysql_secure_installation
Now that we have installed all the necessary dependencies, we can install IMP itself. Run the following command:
sudo apk add php7-horde-imp
IMP is now installed, but we need to configure it before we can use it. You can find the configuration files in /etc/webapps/horde/imp/conf.php.
Edit the configuration file and set the database connection details, such as the database name, database user, and password.
$conf['sql']['phptype'] = 'mysql';
$conf['sql']['hostspec'] = 'localhost';
$conf['sql']['username'] = 'username';
$conf['sql']['password'] = 'password';
$conf['sql']['database'] = 'imp';
Save and close the file.
Finally, start the IMP service and enable it to start at system boot:
sudo rc-service php-fpm7 start
sudo rc-update add php-fpm7
You can now access IMP in your web browser at http://localhost/imp.
In this tutorial, we have shown you how to install IMP on Alpine Linux Latest. You can now use IMP to manage your email messages from a web interface.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
