Connection Rails & System so that Rails can do things like updating nginx block

Question

I am new to rails & I am trying to achieve the bellow scenario

Lets say I have a Model called Sites with Field domain name. & created an entry with domain name "example.com" & It stored to database.

So Now what I am trying to do is after save it will trigger a command to create a Nginx server block with the given Domain name "example.com" right from rails app.

I know Little bit of shell scripting but don't know how I can run the script from rails based on the data saved on rails db.

Any guideline or Code snippets would be very helpful,

Thanks

Technically you can run any script code from ruby, the problem I see here is that to update nginx block you need to execute the script as root, and this would be very a bad idea to do directly from your rail app.
