I'm having difficult to configure Node Manager and AdminServer work on 10.0.1.141. I found nmConnect(domainName='<domain_name>') using default node manager listen 127.0.0.1:5556 to locate node manager service.

(Probably for others that encounter the same). You'll need to edit nodemanager.properties, in <DOMAIN_HOME>/nodemanager/nodemanager.properties

Within that, you will need to edit the ListenAddress directive. If you do so, ensure access is firewalled.

ExecStart and ExecStop need to use /bash/sh before running the StartScript, so it should look like :
ExecStart=/bash/sh <domain_home>/bin/startNodeManager.sh
Else you will get an error like "(code=exited, status=203/EXEC)" as the system doesn't know how to execute that command.

Also the >/dev/null 2>/dev/null & are not need.

Did you change <domain_name> for the actual domain path?
