Order to update server configurations to delete an app powered by PHP-FPM

dragonxi

We would appreciate your advice how to proceed in the following situation:

Status:
(S1) Stopped the php-fpm process serving the app
. stop <-- OK

(S2) Tested php-fpm process has stopped serving the web page
- 502 Bad Gateway <-- OK

(S3) Rerouted the app

(S4) Tested the updated rerouting

https://www.xxxxxxxx.yyy/ <-- OK

(S5) Contemplating how to continue in the situation where

the web page is still working
only references to it have bee deleted from other web sites
fpm process has only been stopped

Question: in which order to update the server configurations ?

(Q1)Applications <-- https://my.opalstack.com/applications/
(a) Proxy Port - can it be deleted safely first, because the fpm process is stopped ?
(b) PHP-FPM - can it be deleted because for example emails are being served ?

(Q2)Site Routes <-- https://my.opalstack.com/routes/

can it be deleted now ?

(Q3)Domains & Subdomains <-- https://my.opalstack.com/domains/

can these be deleted now ?

(Q4)Certificates & Keys <-- https://my.opalstack.com/certificates/

can it be deleted now ?

(Q5) DNS Records <-- https://my.opalstack.com/dns/

can it be deleted now ?

(Q6) Email Address <-- https://my.opalstack.com/mail/

must be deleted first before Mail Users ?

(Q7) Mail Users <-- https://my.opalstack.com/mailusers/

can be deleted only if the Email Addresses have been deleted ?

(Q8) Anything else to update and to take into account ?

time needed by other servers such as mail servers ?

Thanks in advance for any advice!

dragonxi here is the order I recommend to delete all of the items you mentioned:

Run crontab -e as the app's shell user and remove the crontab entries for that app (if there are any).
Stop the app.
Delete the apps, site routes, certificates+keys, mail users, and email addresses in any order you prefer. The order does not matter.
Delete any manual DNS records you have for your domain/subdomain.
Delete the domain/subdomain.

At this time web server changes (like deleting apps and sites) can take around 5 minutes to propagate to the web server. Mail changes can take around 10 minutes.

Also, don't forget that at this time when you delete an app, mail user, shell user, or database the item is not deleted immediately - rather, it is queued to be deleted 24 hours later. If you need it gone quicker then use the trash can icon that appears on the row for the deleted item in the dashboard.
