Hello, I'm new to ISPConfig, last week I setup a multi server setup partially using these guides: https://www.howtoforge.com/tutorial/perfect-server-debian-10-nginx-bind-dovecot-ispconfig-3.1/ https://www.howtoforge.com/multiser...se-servers-on-debian-squeeze-with-ispconfig-3 Here's a break down of my setup: Master - Master server, hosts the ISP web interface, database, runs NGINX and MySQL for the master server db. Web1 - NGINX, MySQL, Mailserver, FTP this server hosts all the websites, databases and mail. NS1 - Bind9 NS2 - Bind9, slave to NS1 Everything has been working great but there is an update to: 3.1.15p1 From what I've read I should update the master server first? The only steps I'm unsure of is what should I choose on each server for these steps: Reconfigure Permissions in master database? Reconfigure Services? Everything on all of these servers is pretty default according to the guide. The only thing I changed was securing the web interface, FTP and mail server SSL certs with LE generated certs outlined here: https://www.howtoforge.com/tutorial/securing-ispconfig-3-with-a-free-lets-encrypt-ssl-certificate/ Thanks in advance, I'm loving ISPConfig so far! EDIT: I just realized I posted this in the wrong forum. Sorry about that.
