want to create a user account for each of the key programs installed on my debian server. For example, for the following programs:
Tomcat Nginx Supervisor PostgreSQL
This seems to be recommended based on my reading online. However, I want to restrict these user accounts as much as possible, so that they dont have a shell login, dont have access to the other programs and are as limited as possible but still functional.
Would anyone mind telling me how this could be achieved? My reading so far suggests this:

pam_nologin
PAM_NOLOGIN(8) Linux-PAM Manual PAM_NOLOGIN(8)NAME
pam_nologin - Prevent non-root users from login
SYNOPSIS
pam_nologin.so [file=/path/nologin] [successok]
DESCRIPTION
pam_nologin is a PAM module that prevents users from logging into the system when /var/run/nologin or /etc/nologin exists. The contents of
the file are displayed to the user. The pam_nologin module has no effect on the root user's ability to log in.
OPTIONS
file=/path/nologin
Use this file instead the default /var/run/nologin or /etc/nologin.
successok
Return PAM_SUCCESS if no file exists, the default is PAM_IGNORE.
MODULE TYPES PROVIDED
The auth and acct module types are provided.
RETURN VALUES
PAM_AUTH_ERR
The user is not root and /etc/nologin exists, so the user is not permitted to log in.
PAM_BUF_ERR
Memory buffer error.
PAM_IGNORE
This is the default return value.
PAM_SUCCESS
Success: either the user is root or the nologin file does not exist.
PAM_USER_UNKNOWN
User not known to the underlying authentication module.
EXAMPLES
The suggested usage for /etc/pam.d/login is:
auth required pam_nologin.so
NOTES
In order to make this module effective, all login methods should be secured by it. It should be used as a required method listed before any
sufficient methods in order to get standard Unix nologin semantics. Note, the use of successok module argument causes the module to return
PAM_SUCCESS and as such would break such a configuration - failing sufficient modules would lead to a successful login because the nologin
module succeeded.
