Activating Prometheus Service

Hi everyone,

I am rookie on prometheus and trying to install to VirtualBox installed CentOS8. I see following error when I try to run service. Can someone help me?

Error: Failed to start prometheus.service. Unit prometheus.service has a bad unit file setting.

Service file:

[Unit]
Description=Prometheus
Wants=network-online.target
After=network-online.target

[Service]
User=prometheus
Group=prometheus
Type=simple
ExecStart=/usr/local/bin/prometheus \
    --config.file /etc/prometheus/prometheus.yml \
    --storage.tsdb.path /var/lib/prometheus/ \
    --web.console.templates=/etc/prometheus/consoles \
    --web.console.libraries=/etc/prometheus/console_libraries

[Install]
WantedBy=multi-user.target

Maybe try Ansible-Prometheus.
