安装

壹， prometheus server 安装

github

1,上传安装包

# 解压到/opt/module 目录下：
mkdir /opt/module
tar  -zxvf  prometheus-2.29.1.linux-amd64.tar.gz -C /opt/module
# 修改目录名：
cd /opt/module
mv prometheus-2.29.1.linux-amd64 prometheus-2.29.1
ln -s /opt/module/prometheus-2.29.1/ /usr/local/prometheus 
mkdir /usr/local/prometheus/data

2, 修改配置文件

# scrape_configs字段的配置
cat  prometheus.yml
scrape_configs:
	- job_name: 'prometheus'
	  static_configs:
        - targets: ["node1:9090"]
# 添加PushGateway 监控配置
	- job_name: 'pushgateway'
	  static_configs:
        - targets: ["node1:9091"]
          labels:
           instance: pushgateway         
# 添加 Node Exporter 监控配置
	- job_name: 'node exporter'
	  static_configs:
		- targets: ['node1:9100','node2:9100','master3:9100']

3，配置启动文件

cat << EOF >/usr/lib/systemd/system/prometheus.service
[Unit]
Description=https://prometheus.io
[Service]
Restart=on-failure
ExecStart=/usr/local/prometheus/prometheus \
--storage.tsdb.path=/usr/local/prometheus/data/ \
--config.file=/usr/local/prometheus/prometheus.yml
[Install]
WantedBy=multi-user.target
EOF

systemctl daemon-reload
systemctl status prometheus
