0x00 Node_Exporter 安装

1、从官网下载 node_exporter

wget https://github.com/prometheus/node_exporter/releases/download/v1.6.1/node_exporter-1.6.1.linux-amd64.tar.gz
tar -zxf node_exporter-1.6.1.linux-amd64.tar.gz
mv node_exporter-1.6.1.linux-amd64/node_exporter /usr/local/bin

2、安装启动本地服务

useradd --no-create-home --shell /bin/false node_exporter
chown node_exporter:node_exporter /usr/local/bin/node_exporter

创建服务

vim /etc/systemd/system/node_exporter.service

[Unit]
Description=Node Exporter
After=network.target

[Service]
User=node_exporter
Group=node_exporter
Type=simple
ExecStart=/usr/local/bin/node_exporter

[Install]
WantedBy=multi-user.target

3、启动验证

systemctl daemon-reload
systemctl start node_exporter
# 验证服务
curl localhost:9100/metrics

4、prometheus监控

在prometheus 服务器上执行

vim /etc/prometheus/prometheus.yml

- job_name: 'nodeexporter'
  static_configs:
  - targets: ['clientIP:9100']

# 重启
systemctl restart prometheus

0x01 Prometheus Server 安装

1、创建用户、数据目录

groupadd --system prometheus
useradd -s /sbin/nologin --system -g prometheus prometheus
# 数据目录
mkdir -p /apps/data_base/prometheus_base
chown -R prometheus:prometheus /apps/data_base/prometheus_base

2、下载执行文件

wget https://github.com/prometheus/prometheus/releases/download/v2.45.0/prometheus-2.45.0.linux-amd64.tar.gz
tar -zxf prometheus-2.45.0.linux-amd64.tar.gz
cd prometheus-2.45.0.linux-amd64
mv prometheus promtool /usr/local/bin/
mkdir /etc/prometheus
mv prometheus.yml /etc/prometheus/
mv consoles/ console_libraries/  /etc/prometheus/

3、配置启动参数

不用动

4、配置系统服务

vim /etc/systemd/system/prometheus.service

[Unit]
Description=Prometheus
Documentation=https://prometheus.io/docs/introduction/overview/
Wants=network-online.target
After=network-online.target

[Service]
Type=simple
Environment="GOMAXPROCS=1"
User=prometheus
Group=prometheus
ExecReload=/bin/kill -HUP $MAINPID
ExecStart=/usr/local/bin/prometheus \
  --config.file=/etc/prometheus/prometheus.yml \
  --storage.tsdb.path=/apps/data_base/prometheus_base \
  --web.console.templates=/etc/prometheus/consoles \
  --web.console.libraries=/etc/prometheus/console_libraries \
  --web.listen-address=0.0.0.0:9090 \
  --web.external-url=

SyslogIdentifier=prometheus
Restart=always

[Install]
WantedBy=multi-user.target

说明：

• Environment="GOMAXPROCS=1", 1 改为主机CPU的核心数
• --storage.tsdb.path=/apps/data_base/prometheus_base 　这里修改为数据目录

5、启动服务

systemctl daemon-reload
systemctl start prometheus
systemctl enable prometheus

查看状态:

systemctl status prometheus

验证

curl localhost:9090

0x02 Alertmanager

1、准备

自行下载、解压

mv alertmanager amtool /usr/local/bin/
mkdir -p /etc/alertmanager
mv alertmanager.yml /etc/alertmanager/
mkdir -p /apps/data_base/alertmanager

2、配置服务

vim /etc/systemd/system/alertmanager.service

[Unit]
Description=alertmanager server daemon
Documentation=https://prometheus.io/docs/introduction/overview/
After=network.target[Service]


[Service]
Type=simple
ExecStart=/usr/local/bin/alertmanager --config.file=/etc/alertmanager/alertmanager.yml --storage.path=/apps/data_base/alertmanager
ExecReload=/bin/kill -HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
KillMode=process
Restart=on-failure
RestartSec=42s[Install]

[Install]
WantedBy=multi-user.target

3、启动服务

systemctl daemon-reload
systemctl start alertmanager
systemctl enable alertmanager
systemctl status alertmanager

curl localhost:9093
