Failed to start cloudera-scm-agent.service: Unit not found.

[root@datenode1 ~]# systemctl start cloudera-scm-agent

Failed to start cloudera-scm-agent.service: Unit not found.

[root@datanode1 ~]# rpm -qa | grep cloude

cloudera-manager-daemons-5.13.1-1.cm5131.p0.2.el7.x86_64

cloudera-manager-agent-5.13.1-1.cm5131.p0.2.el7.x86_64

I'm trying to install via cloudera manager's wizard, everything works until starting the cloudera-scm-agent, which fails with same error above 'Failed to start cloudera-scm-agent.service: Unit not found.'

This is on centos 7,  selinux is off, the firewall is off, ssh keys are good as is the hostnames.

Suggestions?

Many thanks,

I was able to start the agents manually via :

/usr/sbin/cmf-agent --daemon --comm_name cmf-agent --pidfile /var/run/cloudera-scm-agent/cloudera-scm-agent.pid
