SquirrelMail is an open-source web-based email client that allows you to access your email from anywhere with an internet connection. In this tutorial, we will explain how to install SquirrelMail on Alpine Linux Latest.
Before installing SquirrelMail on your Alpine Linux system, ensure that you have the following:
Apache is the most widely used web server that supports SquirrelMail. You can install Apache using the following command:
sudo apk add apache2
Once the Apache2 installation is complete, start and enable the Apache2 webserver using the commands:
sudo rc-service apache2 start
sudo rc-update add apache2
SquirrelMail is a PHP-based application; therefore, you need to install PHP and its extensions. Use the following command to install PHP:
sudo apk add php7 php7-apache2 php7-iconv php7-imap php7-openssl php7-mbstring php7-session
Download the latest SquirrelMail release from the official website https://squirrelmail.org.
cd /tmp
wget https://squirrelmail.org/download.php -O squirrelmail.tar.gz --no-check-certificate
Extract the downloaded SquirrelMail package using the following command:
sudo tar -zxvf squirrelmail.tar.gz -C /var/www/localhost/htdocs/
Navigate to the SquirrelMail directory and configure SquirrelMail using the following command:
cd /var/www/localhost/htdocs/squirrelmail
sudo ./configure
SquirrelMail requires specific PHP configurations to be secured:
sudo sed -i 's/.*session.auto_start =.*/session.auto_start = Off/g' /etc/php7/php.ini
sudo sed -i '/disable_functions/ s/^;/;/' /etc/php7/php.ini
Create an Apache virtual host file for SquirrelMail. Run the following command to create the squirrelmail.conf file:
sudo vim /etc/apache2/conf.d/squirrelmail.conf
Add the following lines to the squirrelmail.conf file:
Alias /squirrelmail /var/www/localhost/htdocs/squirrelmail
<Directory /var/www/localhost/htdocs/squirrelmail>
Options FollowSymLinks
DirectoryIndex index.php
Require all granted
</Directory>
Restart the Apache webserver to apply changes:
sudo rc-service apache2 restart
Open your web browser and enter your server's IP address or hostname and /squirrelmail as the URL (for example, http://192.168.0.100/squirrelmail or http://yourhostname.com/squirrelmail).
You will see the SquirrelMail login page; use your email address and password to login and access your email.
Congratulations! You have successfully installed SquirrelMail on Alpine Linux Latest. You can now access your emails on the go by logging in to your SquirrelMail installation through any browser.
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!
