CentOS 7 Installation
Create dependencies
~$ sudo yum install -y wget ~$ sudo groupadd --system prometheus ~$ sudo useradd -s /sbin/nologin --system -g prometheus prometheus ~$ sudo mkdir /var/lib/prometheus ~$ for i in rules rules.d files_sd; do sudo mkdir -p /etc/prometheus/${i}; done ~$ mkdir -p /tmp/prometheus && cd /tmp/prometheus
Download and setup
~$ curl -s https://api.github.com/repos/prometheus/prometheus/releases/latest | grep browser_download_url | grep linux-amd64 | cut -d '"' -f 4 | wget -qi - ~$ tar xvf prometheus*.tar.gz ~$ cd prometheus*/ ~$ sudo mv prometheus promtool /usr/local/bin/ ~$ sudo mv prometheus.yml /etc/prometheus/prometheus.yml ~$ sudo mv consoles/ console_libraries/ /etc/prometheus/ ~$ cd ~/ ~$ rm -rf /tmp/prometheus
Create config
~$ sudo vim /etc/prometheus/prometheus.yml
prometheus config
# my global config global: scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute. evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute. # scrape_timeout is set to the global default (10s). # Alertmanager configuration alerting: alertmanagers: - static_configs: - targets: # - alertmanager:9093 # Load rules once and periodically evaluate them according to the global 'evaluation_interval'. rule_files: # - "first_rules.yml" # - "second_rules.yml" # A scrape configuration containing exactly one endpoint to scrape: # Here it's Prometheus itself. scrape_configs: # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config. - job_name: 'prometheus' # metrics_path defaults to '/metrics' # scheme defaults to 'http'. static_configs: - targets: ['localhost:9090']
Create systemd service
