Prometheus搭建

1、下载Prometheus(建议使用2.x版本）

wget https://github.com/prometheus/prometheus/releases/download/v2.8.0/prometheus-2.8.0.linux-amd64.tar.gz

tar xf prometheus-2.8.0.linux-amd64.tar.gz -C /usr/local/

mv /usr/local/prometheus-2.8.0.linux-amd64 /usr/local/prometheus

cd /usr/local/prometheus

2、查看Prometheus版本

./promethues --version

#显示如下

prometheus, version 2.8.0 (branch: HEAD, revision: 59369491cfdfe8dcb325723d6d28a837887a07b9)

  build user:       root@4c4d5c29b71f

  build date:       20190312-07:46:58

  go version:       go1.11.5

3、启动Prometheus（后台）

#默认启动9090端口，读取当前目录下的promethues.yml配置

cd /usr/local/promethus && nohup ./promethues &

4、以服务方式启动

#添加到系统服务，方便于管理

vi /etc/systemd/system/prometheus.service

#添加如下内容

[Unit]

Description=Prometheus Monitoring System

Documentation=Prometheus Monitoring System

[Service]

ExecStart=/usr/local/prometheus/prometheus \

  --config.file=/usr/local/prometheus/prometheus.yml \

  --web.listen-address=:9090

[Install]

WantedBy=multi-user.target

5、启动服务，设置开机自启

systemctl daemon-reload

systemctl enable prometheus

systemctl start prometheus

6、访问Promethues主页

访问http://{IP}:9090，如果是本机则是http://localhost:9090
