I followed the Centos 7.4 guide, and all went well. I'm now testing migrating a Wordpress site to it and all went ok. However now I'm trying to get Wordpress to self-update and upgrade plugins. However it prompts for ftp info. It works if I enter the site FTP username/password, but I would like to not have to do this... How can I get this working to self-update without that additional step like it does with 3rd party web hosts?
