问题
I am using php/mysql on linux servers. I want to create a user sub domain for each user upon sign up. For instance, john doe --> johndoe.example.com
The issue is, we are going to allow customizations such as adding custom features for clients wanting customizations. So, is it better we automate the process or manually create sub domains for clients requiring customizations and let other users just use basic login?
And how can i automate the process if need be?
回答1:
Instead of creating subdomains, have a wildcard subdomain which is mapped into one folder and with PHP figure out which user's data you want to show.
If you are using a cPanel hosting, creating a wildcard subdomain should be pretty easy and wont require any manual adjustment to the httpd.conf file. Otherwise whenever you will add individual subdomains Apache will be restarted in the background, which is not at all good.
I rephrased my answer for clearer understanding.
