2.1.rpm部署监控组件

# 一、安装go
 1. [下载链接](https://studygolang.com/dl)

1. 解压安装

```
# tar -C /usr/local/ -xvf go1.14.1.linux-amd64.tar.gz
```

2. 配置环境变量

```bash
# vim /etc/profile
export PATH=$PATH:/usr/local/go/bin
# source /etc/profile
```

3. 验证

# 二、安装prometheus

- [下载链接](https://prometheus.io/download/)

1. 安装

```bash
mkdir -p /usr/local/prometheus/{bin,etc}
wget https://github.com/prometheus/prometheus/releases/download/v2.43.0/prometheus-2.43.0.linux-amd64.tar.gz
tar -xvf prometheus-2.43.0.linux-amd64.tar.gz
mv prometheus-2.43.0.linux-amd64/* /usr/local/prometheus
mv /usr/local/prometheus/prometheus /usr/local/prometheus/bin/
mv /usr/local/prometheus/promtool /usr/local/prometheus/bin/
mv /usr/local/prometheus/prometheus.yml /usr/local/prometheus/etc/
```

2. 创建服务脚本

```bash
tee > /usr/lib/systemd/system/prometheus.service <<EOF
[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=root
Group=root
# --storage.tsdb.path是可选项，默认数据目录在/data目录下
# --web.enable-lifecycle 允许通过API接口实现热更新
ExecStart=/usr/local/prometheus/bin/prometheus \
--config.file=/usr/local/prometheus/etc/prometheus.yml \
--web.enable-lifecycle --log.level=info \
--storage.tsdb.path=/data/prometheus/tsdb
Restart=on-failure

[Install]
WantedBy=multi-user.target
EOF
```

3. 启动prometheus

```
systemctl daemon-reload
systemctl enable prometheus.service
systemctl start prometheus.service
systemctl status prometheus
```

4. 验证

浏览器打开 IP:9090 端口即可打开普罗米修斯自带的监控页面

# 三、安装Grafana

1. [下载链接](https://grafana.com/grafana/download)

1. 安装

```
yum install -y https://dl.grafana.com/enterprise/release/grafana-enterprise-11.1.4-1.x86_64.rpm
```

2. 启动

```
systemctl enable grafana-server.service
systemctl start grafana-server.service
```

3. 访问grafana

浏览器访问 IP:3000端口 即可打开grafana页面

默认用户名密码都是 `admin`

初次登录会要求修改默认的登录密码

4. 添加prometheus数据源

-  点击主界面的“Add data source”

![image.png](/media/202408/2.1.23381472_image4.png)

- 选择prometheus

![image.png](/media/202408/2.1.23381472_image5.png)

- 添加url地址并保存

![image.png](/media/202408/2.1.23381472_image6.png)

- 添加dashboard

# 四、使用node-exporter监控linux主机

1. 被监控的机器安装node-exporter

```bash
wget https://github.com/prometheus/node_exporter/releases/download/v1.8.2/node_exporter-1.8.2.linux-amd64.tar.gz
tar -zxf node_exporter-*.linux-amd64.tar.gz
mv node_exporter-*.linux-amd64/node_exporter /usr/local/prometheus/bin/
```

2. 创建服务脚本

```bash
tee > /usr/lib/systemd/system/node_exporter.service  <<EOF
[Unit]
Description=node_exporter
After=network.target

[Service]
Type=simple
User=root
ExecStart=/usr/local/prometheus/bin/node_exporter
Restart=on-failure

[Install]
WantedBy=multi-user.target
EOF
```

3. 启动node_exporter

```bash
systemctl daemon-reload
systemctl enable node_exporter.service
systemctl start node_exporter.service
systemctl status node_exporter.service
```

4. prometheus服务端添加监控项，然后重启prometheus

```bash
# vim /usr/local/Prometheus/prometheus.yml
os_full=$([ -f /etc/os-release ] && awk -F'[= "]' '/PRETTY_NAME/{print $3,$4,$5}' /etc/os-release)
if [[ $os_full =~ 'Ubuntu' ]]; then IpCommand='/bin/ip';elif [[ $os_full =~ 'CentOS' ]]; then IpCommand='/sbin/ip';fi
localIP=`$IpCommand address|grep $(cat /proc/net/dev|awk '{print $1,$10}'|grep -Ev 'Inter|lo|face'|sort -rn -k2|head -1|awk -F: '{print $1}')|grep inet.*global|tail -1|awk '{print $2}'|awk -F/ '{print $1}'`

cat >> /usr/local/prometheus/etc/prometheus.yml <<EOF
  - job_name: "node-${localIP}"
    static_configs:
      - targets: ["${localIP}:9100"]
EOF

systemctl restart prometheus.service 
```
