在线安装consul

sudo yum install -y yum-utils && sudo yum-config-manager --add-repo https://rpm.releases.hashicorp.com/RHEL/hashicorp.repo && sudo yum -y install consul

2、添加consul配置文件

vi /etc/consul.d/server.json (新建server.json配置文件)

{
    "server": true,
    "bootstrap": true,
    "advertise_addr": "{{ GetInterfaceIP \"eth0\" }}",
    "ui_config": {
        "enabled": true
    },
    "data_dir": "/etc/consul",
    "log_level": "INFO",
    "addresses": {
        "http": "0.0.0.0"
    },
    "ports": {
        "http": 8500
    }
}

3、启动consul

systemctl start consul && systemctl enable consul

打开网址查看:http://172.16.131.28:8500/ui/ (需要替换自己的IP)(访问不了时,关闭防火墙或者防火墙添加端口)

注意事项:

如果启动失败,则修改配置文件/usr/lib/systemd/system/consul.service,设置启动用户为root,然后重启

4、服务注册与反注册

5、与Prometheus集成

vim /home/prometheus-2.37.0.linux-amd64/prometheus.yml

image-20220825155909051

  - job_name: "nano"
    consul_sd_configs:
      - server: "127.0.0.1:8500"
        services: [ "nano-vm-exporter" ]
    relabel_configs:
      - regex: __meta_consul_service_metadata_(.+)
        action: labelmap
    honor_labels: true

说明:job name就叫nano,从127.0.0.1:8500抓取数据,127.0.0.1:8500就是consul的地址,发现服务名称叫nano-vm-exporter下的服务,替换标签信息,保留原始标签
