一、概述
Prometheus官网文档: https://prometheus.io/docs/introduction/overview/

各组件默认端口:
prometheus ：9090
node 默认端口：9091(原默认端口为9100,与elasticsearch端口冲突，故这里改为9091)
mysql_exporter默认端口：9104
redis_exporter 默认端口：9121
rabbitmq_prometheus 默认端口： 15692
elasticsearch_exporter 默认端口： 9114
kafka_exporter 默认端口： 9308
blackbox_exporter默认端口: 9115
mongodb_exporter 端口: 9216
alertmanager默认端口：9093

注意：
1.本文使用的各程序版本是当下最新版本，实际需要到官网去看是否有更新的版本，推荐使用最新版本。
2.本文Prometheus等程序安装及监控目标都为Linux环境(CentOS7)
3.Promethues支持pull和push两种方式，本文描述的是pull方式
4.exporter一般都部署在监控目标服务器上，blackbox_exporter则和prometheus部署在一起

二、安装Prometheus
2.1.安装Prometheus
[root@server ~]# cd /usr/local/src
[root@server src]# wget https://github.com/prometheus/prometheus/releases/download/v2.28.1/prometheus-2.28.1.linux-amd64.tar.gz

六、监控RabbitMQ
6.1.安装rabbitmq_prometheus
RabbitMQ 3.8版本以后已内置支持Prometheus插件
https://www.rabbitmq.com/prometheus.html

启用方式：

[root@dbserver src]# rabbitmq-plugins enable rabbitmq_prometheus
默认端口号为15692
启动后可访问 http://ip:15692/metrics

如要修改默认配置，对应配置文件为 /etc/rabbitmq/rabbitmq.conf
prometheus.path = /metrics
prometheus.tcp.port = 15692

也可以使用单独的rabbitmq_exporter来监控，可适应rabbitmq3.8以前版本
（注意 3.6.x与更早版本监控有差别，需要注意)
https://github.com/kbudde/rabbitmq_exporter/

6.2.验证rabbitmq_prometheus
[root@dbserver src]# curl "http://127.0.0.1:15692/metrics"
6.3.防火墙配置
[root@dbserver src]# firewall-cmd --permanent --add-port=15692/tcp
[root@dbserver src]# firewall-cmd --reload

#也可以限定仅能指定的IP访问
[root@dbserver src]# firewall-cmd --permanent --add-rich-rule="rule family="ipv4" source address="192.168.1.100" port protocol="tcp" port="15692" accept"

#或可直接关闭防火墙

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
    - targets: ['127.0.0.1:9090']

  - job_name: 'rabbitmq_exporter'
    static_configs:
    - targets: ['192.168.1.100:15692']
      labels:
        service: 服务A-RabbitMQ
    - targets: ['192.168.1.101:15692']
      labels:
        service: 服务B-RabbitMQ

[root@dbserver src]# systemctl start kafka_exporter
[root@dbserver src]# systemctl status kafka_exporter
[root@dbserver src]# systemctl enable kafka_exporter
8.4.验证kafka_exporter
[root@dbserver src]# curl "http://127.0.0.1:9308/metrics"
8.5.防火墙配置
[root@dbserver src]# firewall-cmd --permanent --add-port=9308/tcp
[root@dbserver src]# firewall-cmd --reload

#也可以限定仅能指定的IP访问
[root@dbserver src]# firewall-cmd --permanent --add-rich-rule="rule family="ipv4" source address="192.168.1.100" port protocol="tcp" port="9308" accept"

#或可直接关闭防火墙
[root@dbserver src]# systemctl stop firewalld
[root@dbserver src]# systemctl disable firewalld

8.6.Prometheus侧配置
8.6.1.prometheus.yml配置调整
[root@dbserver src]# vi /usr/local/prometheus/prometheus/prometheus.yml
scrape_configs:
  # The job name is added as a label `job=` to any timeseries scraped from this config.
  - job_name: 'prometheus'

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
    - targets: ['127.0.0.1:9090']

  - job_name: 'elasticsearch_exporter'
    static_configs:
    - targets: ['192.168.1.100:9308']
      labels:
        service: 服务A-Kafka
    - targets: ['192.168.1.101:9308']
      labels:
        service: 服务B-Kafka
8.6.2.校验配置正确性
[root@dbserver src]# /usr/local/prometheus/prometheus/promtool check config /usr/local/prometheus/prometheus/prometheus.yml 
8.6.3.重新加载配置
[root@dbserver src]# systemctl reload prometheus
8.6.4.验证结果
访问http://ip:9090/targets查看

九、监控Doris
Doris已内置支持对FE,BE的Promotheus监控支持
无需额外配置，防护墙允许Prometheus访问 8030,8040端口即可

9.1.验证doris_prometheus
#FE
[root@dbserver src]# curl "http://127.0.0.1:8030/metrics"

#BE
[root@dbserver src]# curl "http://127.0.0.1:8040/metrics"
9.2.Prometheus侧配置
9.2.1.prometheus.yml配置调整
[root@dbserver src]# vi /usr/local/prometheus/prometheus/prometheus.yml
scrape_configs:
  # The job name is added as a label `job=` to any timeseries scraped from this config.
  - job_name: 'prometheus'

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
    - targets: ['127.0.0.1:9090']

  - job_name: 'doris_cluster'
    static_configs:
    - targets: ['192.168.1.100:8030','192.168.1.101:8030']
      labels:
	    service: 服务A-Doris-FE
        group: fe

    - targets: ['192.168.1.102:8040','192.168.1.103:8040','192.168.1.104:8040']
      labels:
	    service: 服务A-Doris-BE
        group: be

9.2.2.校验配置正确性
[root@dbserver src]# /usr/local/prometheus/prometheus/promtool check config /usr/local/prometheus/prometheus/prometheus.yml 
9.2.3.重新加载配置
[root@dbserver src]# systemctl reload prometheus
9.2.4.验证结果
访问http://ip:9090/targets查看

十、监控端口(HTTP/TCP等)
10.1.安装blackbox_exporter
这里使用 blackbox_exporter来监控HTTP/TCP

[root@appserver ~]# cd /usr/local/src/
[root@appserver src]# wget https://github.com/prometheus/blackbox_exporter/releases/download/v0.19.0/blackbox_exporter-0.19.0.linux-amd64.tar.gz
[root@appserver src]# tar xvf blackbox_exporter-0.19.0.linux-amd64.tar.gz -C /usr/local/prometheus/
[root@appserver src]# mv /usr/local/prometheus/blackbox_exporter-0.19.0.linux-amd64/ /usr/local/prometheus/blackbox_exporter
10.2.将blackbox_exporter配置成系统服务
编辑启动文件

[root@appserver src]# vi /etc/systemd/system/blackbox_exporter.service

ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -SIGINT $MAINPID

[Install]
WantedBy=multi-user.target
10.3.通过systemctl启动blackbox_exporter
