Create User For Prometheus

groupadd -r prometheus
useradd -r -g prometheus -s /sbin/nologin -d /usr/hostonnet/prometheus/ -c "prometheus Daemons" prometheus
chown -R prometheus:prometheus /usr/hostonnet/prometheus/
chown prometheus:prometheus /var/log/prometheus.log

Run prometheus on Boot

chkconfig --add prometheus
chkconfig prometheus on

Verify it is enabled

[root@backup ~]# chkconfig --list | grep prome
prometheus     	0:off	1:off	2:on	3:on	4:on	5:on	6:off
[root@backup ~]# 

“3:on” will start prometheus on run level 3, that is normal boot.

Start Prometheus

[root@backup ~]# service prometheus start
Starting prometheus:                                       [  OK  ]
[root@backup ~]#
