prometheus部署

1.prometheus安装

软件下载:

wget https://dl.grafana.com/oss/release/grafana-6.4.2-1.x86_64.rpm

https://github.com/prometheus/prometheus/releases/download/v2.13.0/prometheus-2.13.0.linux-amd64.tar.gz

wget https://golang.org/doc/install?download=go1.13.1.linux-amd64.tar.gz

说明:虚拟机Centos7 环境下进行安装.

1.1环境装备

配置golang的环境

wget https://golang.org/doc/install?download=go1.13.1.linux-amd64.tar.gz

tar -C /usr/local/ -xvf    go1.13.1.linux-amd64.tar.gz

添加到环境变量中

vim /etc/profile

export PATH=$PATH:/usr/local/go/bin

重载环境变量

source /etc/profile

查看版本

go   version

1.2安装Prometheus

tar -C /usr/local/ -xvf   prometheus-2.13.0.linux-amd64.tar.gz

ln -sv /usr/local/prometheus-2.13.0.linux-amd64/   /usr/local/prometheus

启动:

/usr/local/prometheus/prometheus  --storage.tsdb.path=/data/     --config.file=/usr/local/prometheus/prometheus.yml

暂时关闭防火墙

systemctl stop firewalld.service

登录:http://192.168.31.91:9090

1.3安装Grafana

rpm -ivh --nodeps grafana-6.4.2-1.x86_64.rpm

启动:

systemctl daemon-reload

systemctl enable grafana-server.service

systemctl start grafana-server.service

登录:http://192.168.31.91:3000/login  初始密码:admin admin

安装饼图插件:

grafana-cli plugins install grafana-piechart-panel

注意Grafana 密码重置

yum的安装方式,源码安装方式找到grafana.db文件

sqlite3 /var/lib/grafana/grafana.db

update user set password = '59acf18b94d7eb0694c61e60ce44c110c7a683ac6a8f09580d626f90f4a242000746579358d77dd9e570e83fa24faa88a8a6', salt = 'F3FAxVm33R' where login = 'admin';

1.4.配置Grafana

添加prometheus数据源

点击主界面的“Add data source”

Dashboards页面选择“Prometheus 2.0 Stats”

Settings页面填写普罗米修斯地址并保存

如果需要告警的配置需要下载alertmanager

Prometheus的告警机制是server推送告警到alertmanger,配置告警规则和告警方式

插件下载地址https://github.com/prometheus/alertmanager/releases/download/v0.19.0/alertmanager-0.19.0.linux-amd64.tar.gz

具体架构图如下：

如果在prometheus的http://localhost:9090/管理界面没有数据同时又No datapoints found报错显示

解决方案:一定要修改服务器的时间
