Background worker not working after install multiple bench on the same server

Hello, I have a dedicated server CentOS, I installed frappe bench on it from the root.

After that I create multiple users on the server and each user has a domain or sub-domain.

Then for each user I install erpnext using bench init … create new site … etc.

I faced some issues with reddis and nginx not working because the redis and nginx are shared with all users from root as well bech, so i changed the ports in each bench to be different and all working fine now and all websites are working.

But the issue now the scheduler and workers, background workers not working and only work for the first installed site, in supervisor I get these errors

So when i open the supervisor.conf for the working site i see the bench path correctly like this:

command=/usr/local/bin/bench schedule

command=/usr/local/bin/bench worker --queue default

But in the none working sites the path is set to ‘none’ and i tried to modify it manually and execute ‘bench setup supervisor’ in the site but it did not work, here is an image of the non working sites:

Please advice,

I did not figure it out yet but i found a chart on frappe docs similar to the architecture I am talking about

Problem resolved by running production setup for each site from whm root user
