Roundcube
Prerequisite
This article is part of the emails series. It is assumed that you already covered Dovecot and Exim.
You will also need the following software:
- Nginx as a webserver
- PHP
- MariaDB as a Database server
- Let’s Encrypt to get an HTTPS certificate
- Fail2Ban. Optional but recommended for security.
Install
Roundcube
$ sudo apt install roundcube roundcube-mysql roundcube-plugins roundcube-plugins-extra apache2-
Warning: the apache2- at the end of the list is preventing the automatic installation of Apache. If you have already Apache installed, you need to remove that from the list as it would uninstall it otherwise.
The installer will ask you the following questions:
- Configure database for roundcube with dbconfig-common?
- yes
- Database type to be used by roundcube
- mysql
- Password of the database's administrative user
- Provide your MariaDB root password
- MySQL application password for roundcube
- Keep blank
PHP
Edit file /etc/php/7.0/mods-available/local-common.ini
and add /var/lib/roundcube/:/usr/share/roundcube/:/etc/roundcube/:/var/log/roundcube/
to the open_basedir
setting.
Reload PHP:
$ sudo systemctl reload php7.0-fpm.service
Web Server
- Create the config file
/etc/nginx/sites-available/mail.example.org
server { include snippets/listen-http.conf; server_name mail.example.org; access_log /var/log/nginx/mail.example.org.access.log; error_log /var/log/nginx/mail.example.org.error.log; include snippets/https-permanent-redirect.conf; } server { include snippets/listen-https.conf; server_name mail.example.org; access_log /var/log/nginx/mail.example.org.access.log; error_log /var/log/nginx/mail.example.org.error.log; include snippets/acme-challenge.conf; #include snippets/ssl.conf; #ssl_certificate /etc/letsencrypt/live/mail.example.org/fullchain.pem; #ssl_certificate_key /etc/letsencrypt/live/mail.example.org/privkey.pem; #include snippets/hsts.conf; client_max_body_size 10G; # set max upload size root /var/lib/roundcube/; location ~ ^/(config|temp|logs)/ { deny all; } location ~ /\. { deny all; access_log off; log_not_found off; } index index.php; location ~ \.php$ { try_files $uri =404; include fastcgi.conf; fastcgi_index index.php; fastcgi_pass php; } }
- Activate the configuration with
$ sudo nginx_modsite -e mail.example.org Would you like to reload the Nginx configuration now? (Y/n) Y
- Edit file
/usr/local/etc/certmanage/main.json
and add the following to the list{ "domains": ["mail.example.org"], "reload": [["/bin/systemctl", "reload", "nginx.service"]] }
- Get your certificate
$ sudo /usr/local/sbin/certmanage Renewing certificate for mail.example.org that will expire on 0001-01-01 Saving debug log to /var/log/letsencrypt/letsencrypt.log Starting new HTTPS connection (1): acme-v01.api.letsencrypt.org Obtaining a new certificate Performing the following challenges: http-01 challenge for mail.example.org Using the webroot path /var/www/acme-challenge for all unmatched domains. Waiting for verification... Cleaning up challenges Generating key (2048 bits): /etc/letsencrypt/keys/1764_key-certbot.pem Creating CSR: /etc/letsencrypt/csr/1764_csr-certbot.pem IMPORTANT NOTES: - Congratulations! Your certificate and chain have been saved at /etc/letsencrypt/live/mail.example.org/fullchain.pem. Your cert will expire on 2025-03-11. To obtain a new or tweaked version of this certificate in the future, simply run certbot again. To non-interactively renew *all* of your certificates, run "certbot renew" - If you like Certbot, please consider supporting our work by: Donating to ISRG / Let's Encrypt: https://letsencrypt.org/donate Donating to EFF: https://eff.org/donate-le Restarting services: systemctl reload nginx.service
- Uncomment the ssl related lines in
/etc/nginx/sites-available/mail.example.org
and run$ sudo systemctl reload nginx.service
Configuration
