本文主要是介绍Promethues+grafana监控方案部署，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
主机：192.168.68.127
OS：Centos 7.6
1、下载部署prometheus所需要文件包并部署安装
cd /usr/local/src/
wget -c https://github.com/prometheus/prometheus/releases/download/v2.17.1/prometheus-2.22.1.darwin-amd64.tar.gz
mv prometheus-2.17.1.linux-amd64 /usr/local/prometheuscd /usr/local/prometheus/#添加用户，并赋权groupadd prometheus
useradd -g prometheus -s /sbin/nologin prometheus
mkdir -p /var/lib/prometheus
chown -R prometheus:prometheus /var/lib/prometheus/
touch /usr/lib/systemd/system/prometheus.service
chown prometheus:prometheus /usr/lib/systemd/system/prometheus.service
[root@node1 prometheus]# vim /usr/lib/systemd/system/prometheus.service
[Unit]
Description=Prometheus
Documentation=https://prometheus.io/
After=network.target
[Service]
# Type设置为notify时，服务会不断重启
Type=simple
User=prometheus
# --storage.tsdb.path是可选项，默认数据目录在运行目录的./dada目录中
ExecStart=/usr/local/prometheus/prometheus --config.file=/usr/local/prometheus/prometheus.yml --storage.tsdb.path=/var/lib/prometheus
Restart=on-failure[Install]
WantedBy=multi-user.targetsystemctl enable prometheus
systemctl start prometheus
查看确认，验证服务运行
netstat -ntlp
systemctl status prometheus
Prometheus 自带的UI登录:
http://192.168.68.127:9090
在Status菜单下，Statu–>Configuration展示prometheus.yml的配置，如下：
2、下载node_exporter文件包并部署安装
Node_exporter收集机器的系统数据，这里采用prometheus官方提供的exporter，除node_exporter外，官方还提供consul，memcached，haproxy，mysqld等exporter
cd /usr/local/src/
wget https://github.com/prometheus/node_exporter/releases/download/v1.0.0/node_exporter-1.0.0.linux-amd64.tar.gz
tar -xf node_exporter-1.0.0-rc.0.linux-amd64.tar.gz
mv node_exporter-1.0.0-rc.0.linux-amd64 /usr/local/node_exporter
chown -R prometheus:prometheus /usr/local/node_exporter/
设定开机启动
vim /usr/lib/systemd/system/node_exporter.service
[Unit]
Description=node_exporter
Documentation=https://prometheus.io/
After=network.target[Service]
Type=simple
User=prometheus
ExecStart=/usr/local/node_exporter/node_exporter
Restart=on-failure[Install]
WantedBy=multi-user.targetsystemctl enable node_exporter
systemctl start node_exporter
验证：
3、下载grafana文件包安装部署
cd /usr/local/src/
wget https://s3-us-west-2.amazonaws.com/grafana-releases/release/grafana-6.2.0-1.x86_64.rpm
yum localinstall grafana-4.6.2-1.x86_64.rpm
systemctl enable grafana-server
systemctl start grafana-server
添加数据
登录
http://192.168.68.127:3000
默认账号/密码：admin/admin
添加数据：
在登陆首页，点击"Add data source"按钮，跳转到添加数据源页面，配置如下：
Name: prometheus
Type: prometheus
URL: http://localhost:9090/
Access: proxy或Server(Default)
取消Default的勾选，其余默认，点击"Add"，如下：
在"Dashboards"页签下"import"自带的模版，如下：
从grafana官网下载相关的dashboad到本地，然后Grafana-左上角-Dashboard->Import即可。
