I have discourse running on my droplet and would like to install a mail server. I was following this guide (https://www.digitalocean.com/community/tutorials/how-to-configure-a-mail-server-using-postfix-dovecot-mysql-and-spamassasin) and encountered the issue listed below:
* Starting web server apache2 (98)Address already in use: AH00072: make_sock: could not bind to address [::]:80 (98)Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down AH00015: Unable to open logs Action 'start' failed. The Apache error log may have more information.
How do I fix this issue? Discourse requires Ruby on Rails. I’m on Ubuntu 14.04.
Any suggestions? Thanks!
