CentOS7搭建Prometheus监控Linux主机
1.下载安装Prometheus
下载地址：https://github.com/prometheus/prometheus/releases
下载完成后，解压缩
tar -xzvf prometheus-*.tar.gz
进入解压缩后的目录
cd prometheus-*
执行安装命令
./configure --prefix=/usr/local/prometheus/
make && make install
2.配置Prometheus
进入安装目录
cd /usr/local/prometheus/
新建配置文件
vim prometheus.yml

The default is every 1 minute. # A scrape configuration containing exactly one endpoint to scrape: # Here it is scraping itself. scrape_configs: # The job name is added as a label `job=` to any timeseries scraped from this config. - job_name: 'prometheus' # Override the global default and scrape targets from this job every 5 seconds. scrape_interval: 5s scrape_timeout: 5s # metrics_path defaults to '/metrics' # scheme defaults to 'http'. metrics_path: /metrics scheme: http # A scrape configuration for running Apache exporters on specific ports: - job_name: 'apache' scrape_interval: 5s scrape_timeout: 5s metrics_path: /metrics scheme: http # scrape_configs contains job definitions. scrape_configs: # The job name is added as a label job= to any timeseries scraped from this config. - job_name: 'prometheus' # metrics_path defaults to '/metrics' # scheme defaults to 'http'. metrics_path: /metrics scheme: http # A scrape configuration for running Apache exporters on specific ports: - job_name: 'apache' scrape_interval: 5s scrape_timeout: 5s metrics_path: /metrics scheme: http # The job name is added as a label job= to any timeseries scraped from this config. - job_name: 'node' # Override the global default and scrape targets from this job every 5 seconds. scrape_interval: 5s scrape_timeout: 5s metrics_path: /metrics scheme: http # A scrape configuration for running Apache exporters on specific ports: - job_name: 'apache' scrape_interval: 5s scrape_timeout: 5s metrics_path: /metrics scheme: http # The job name is added as a label job= to any timeseries scraped from this config. - job_name: 'mysql' # Override the global default and scrape targets from this job every 5 seconds. scrape_interval: 5s scrape_timeout: 5s metrics_path: /metrics scheme: http
