Prometheus部署

[root@prometheus ~]#wget https://github.com/prometheus/prometheus/releases/download/v2.31.0-rc.0/prometheus-2.31.0-rc.0.linux-amd64.tar.gz
[root@prometheus ~]# tar -xzvf prometheus-2.31.0-rc.0.linux-amd64.tar.gz  -C /usr/local/
[root@prometheus local]# mv prometheus-2.31.0-rc.0.linux-amd64/ prometheus
[root@prometheus local]# cd prometheus/
[root@prometheus prometheus]# mkdir data #创建数据存放目录

[root@prometheus prometheus]# vim /usr/lib/systemd/system/prometheus.service
[root@prometheus prometheus]# cat /usr/lib/systemd/system/prometheus.service
[Unit]
Description=https://prometheus.io

[Service]
Restart=on-failure
ExecStart=/usr/local/prometheus/prometheus --storage.tsdb.path=/usr/local/prometheus/data --config.file=/usr/local/prometheus/prometheus.yml

[Install]
WantedBy=multi-user.target
[root@prometheus prometheus]# cp prometheus.yml prometheus.yml.bak
[root@prometheus prometheus]# systemctl start prometheus

配置systemctl管理

[root@prometheus prometheus]# vim /usr/lib/systemd/system/prometheus.service
[root@prometheus prometheus]# cat /usr/lib/systemd/system/prometheus.service
[Unit]
Description=https://prometheus.io

[Service]
Restart=on-failure
ExecStart=/usr/local/prometheus/prometheus --storage.tsdb.path=/usr/local/prometheus/data --config.file=/usr/local/prometheus/prometheus.yml

[Install]
WantedBy=multi-user.target
[root@prometheus prometheus]# cp prometheus.yml prometheus.yml.bak
[root@prometheus prometheus]# systemctl start prometheus

监控远程Linux主机

[root@node1 ~]# wget https://github.com/prometheus/node_exporter/releases/download/v1.2.2/node_exporter-1.2.2.linux-amd64.tar.gz #github网站连接时好时坏，不断的下载，一直到下载成功！
[root@node1 ~]# systemctl stop firewalld
[root@node1 ~]# setenforce 0
[root@node1 ~]# tar -xvzf node_exporter-1.2.2.linux-amd64.tar.gz  -C /usr/local/
[root@node1 ~]# cd /usr/local/
[root@node1 local]# mv node_exporter-1.2.2.linux-amd64/ node_exporter
[root@node1 node_exporter]# nohup ./node_exporter & #这样启动也可以，但是我不是
[root@node1 node_exporter]# netstat -tnlp

[root@node1 node_exporter]# vim /usr/lib/systemd/system/node_exporter.service
[Unit]
Description=Prometheusnode_exporter

[Service]
User=nobody
ExecStart=/usr/local/node_exporter/node_exporter --log.level=error
ExecStop=/usr/bin/killallnode_exporter

[Install]
WantedBy=default.target
[root@node1 node_exporter]# systemctl start node_exporter  #配置完成之后，这样启动

配置监控

#来到监控节点
[root@prometheus prometheus]# pwd
/usr/local/prometheus
[root@prometheus prometheus]# vim prometheus.yml  #在最后面添加监控主机
  - job_name: "node1"
    static_configs:
      - targets: ["192.168.153.144:9100"]

[root@prometheus prometheus]# ./promtool check config prometheus.yml #检查配置文件语法有无问题

[root@prometheus prometheus]# systemctl restart prometheus

部署Grafana

[root@grafana ~]# wget https://dl.grafana.com/oss/release/grafana-6.4.3-1.x86_64.rpm
[root@grafana ~]# yum -y install grafana-6.4.3-1.x86_64.rpm
[root@grafana ~]# systemctl start grafana-server
[root@grafana ~]# netstat -tnlp
