Linux安装Prometheus+Grafana+node_exporter

Linux安装Prometheus+Grafana+node_exporter

一、安装准备

1.下载prometheus和grafana,以及监控插件

prometheus官网地址：https://prometheus.io/download/
grafana官网地址：https://grafana.com/grafana/download
prometheus github地址： https://github.com/prometheus
windows系统监控exporter
windows_exporter 地址：https://github.com/prometheus-community/windows_exporter/tags
linux系统监控exporter
node_exporter 地址：https://github.com/prometheus/node_exporter/releases

https://github.com/prometheus/node_exporter/releases/download/v0.18.1/node_exporter-0.18.1.linux-amd64.tar.gz

mysql系统监控exporter

mysql_exporter 地址：https://github.com/prometheus/mysqld_exporter/releases/tag/v0.12.1

二、安装配置node_exporter

1.解压node_exporter

tar -zxvf node_exporter-0.18.1.linux-amd64.tar.gz -C /usr/local/

2.配置node_exporter

1)  vim /etc/systemd/system/node_exporter.service

[Unit]
Description=node_exporter
After=network.target
[Service]
Restart=on-failure
ExecStart=/usr/local/node_exporter-0.18.1.linux-amd64/node_exporter
[Install]
WantedBy=multi-user.target

2)  修改了/etc/systemd/system/下的文件，要执行：

systemctl daemon-reload

3. 启动查看node_exporter  

启动: systemctl start node_exporter

查看状态: systemctl status node_exporter

重启: systemctl restart node_exporter

node_exporter 默认启动占用9100端口

4.设置开机启动

设置开机启动:  systemctl enable node_exporter

设置开机不启动: systemctl disable node_exporter

查看是否开机启动: systemctl is-enabled node_exporter

三、安装Prometheus

1.解压到/usr/local/

tar -zxvf prometheus-2.19.1.linux-amd64.tar.gz -C /usr/local/

2.文件重命名

mv /usr/local/prometheus-2.19.1.linux-amd64  /usr/local/prometheus

3.配置Prometheus后台启动

vim /etc/systemd/system/prometheus.service

[Unit]
Description=Prometheus Server
Documentation=https://prometheus.io/docs/introduction/overview/After=network-online.target
[Service]
Restart=on-failureExecStart=/usr/local/prometheus/prometheus --config.file=/usr/local/prometheus/prometheus.yml --storage.tsdb.path=/var/lib/prometheus --web.external-url=http://ip:9090
[Install]
WantedBy=multi-user.target

上面ip地址填外网ip；如果是虚拟机环境，也就是局域网，填内网ip

4. 启动查看prometheus

启动: systemctl start prometheus

查看状态: systemctl status prometheus

重启: systemctl restart prometheus

prometheus 默认启动占用9090端口

5.设置开机启动

设置开机启动: systemctl enable prometheus

设置开机不启动: systemctl disable prometheus

查看是否开机启动: systemctl is-enabled prometheus

四、安装Grafana

1.解压Grafana

tar -zxvf grafana-6.7.3-1.x86_64.rpm.tar -C /usr/local/

2.重命名Grafana

mv grafana-6.7.3-1.x86_64 grafana

3.启动Grafana

启动: systemctl start grafana-server.service

查看状态: systemctl status grafana-server.service

重启: systemctl restart grafana-server.service

Grafana默认占用端口3000
