grafana监控linux,linux Prometheus+Grafana监控服务器性能

1、安装prometheus

安装go

\[root@tiger ~\]\# yum -y install go

安装prometheus 服务器端

\[root@tiger ~\]\# wget https://github.com/prometheus/prometheus/releases/download/v2.9.2/prometheus-2.9.2.linux-amd64.tar.gz

\[root@tiger ~\]\# tar xvf prometheus-2.9.2.linux-amd64.tar.gz -C /usr/local/

\[root@tiger ~\]\# vim /usr/local/prometheus-2.9.2.linux-amd64/prometheus.yml

在里面写清楚监控节点的信息。注意此文件是yml文件，对格式要求很严格。

主机的9090端口是必须配置的，这是prometheus自带的web界面

9100是node\_exporter的默认端口

9104是mysqld\_exporter默认端口，此服务器上为了测试我也装了mysql。

配置完成后，运行服务：\[root@tiger ~\]\# cd /usr/local/prometheus-2.9.2.linux-amd64/

\[root@tiger ~\]\# prometheus //热加载配置

prometheus启动命令添加参数 --web.enable-lifecycle

然后热重启：curl -XPOST http://localhost:9090/-/reload

nohup ./prometheus --web.enable-lifecycle &

这样更改配置文件后就不用关闭再启动prometheus了

然后ip+端口就可以访问了

192.168.3.121:9090

在被监控的mysql机器上安装对应的exporter官网地址

下载完成在服务器上解压

\[root@localhost ~\]\# tar xvf mysqld\_exporter-0.11.0.linux-amd64.tar.gz -C /usr/local/

\[root@localhost ~\]\# nohup /usr/local/mysqld\_exporter-0.11.0.linux-amd64/mysqld\_exporter &

然后访问192.168.3.121:9090。可以看到up，此时就实现了用普罗米修斯监控系统参数。

2、安装grafana

\[root@tiger ~\]\# wget https://dl.grafana.com/oss/release/grafana-5.4.0-1.x86\_64.rpm

\[root@tiger ~\]\# yum localinstall grafana-5.4.0-1.x86\_64.rpm -y

\[root@tiger ~\]\# systemctl start grafana-server

访问192.168.3.121:3000，默认账户密码 admin/admin

回到刚开始的界面，导入下载好的文件包
