CentOS7上docker部署prometheus+grafana

  • 全部关闭防火墙和selinux:
systemctl stop firewalld && systemctl disable firewalld
sed -i 's/=enforcing/=disabled/g' /etc/selinux/config  && setenforce 0
  • 安装docker
curl http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo -o /etc/yum.repos.d/docker.repo

yum makecache fast

yum install -y docker-ce

systemctl start docker && systemctl enable docker

  • 访问 http://192.168.20.218:9090

  • 安装redis_exporter服务端(https://github.com/oliver006/redis_exporter)

docker run -d  --restart=always --name redis_exporter -p 9121:9121 oliver006/redis_exporter --redis.addr=192.168.20.240:6379 --redis.password=3vRgLpTMLHhMSCflL1iq

  • 添加prometheus配置项

    static_configs:
    - targets: ['192.168.20.218:9121']

重启prometheus

docker restart prometheus
  • 安装influxdb(这里安装的是1.8.0版本的,2.0版本需要用户名密码设置)
docker run -d --name influxdb -p 8086:8086 -v /home/prom/influxdb_data:/var/lib/influxdb influxdb:1.8.10

安装完成后需要进入到容器里创建一个jmeter数据库

docker exec -it influxdb influx
Connected to http://localhost:8086 version 1.8.10
InfluxDB shell version: 1.8.10
> create database jmeter;
>exit
  • jmeter配置
    在jmeter里添加“Backend Listener”,具体配置信息如下图:

  • 遇到问题

  1. 报错:dial tcp 192.168.20.218:9093: connect: no route to host
  • 解决方法:
iptables -P INPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -P OUTPUT ACCEPT
iptables -F
  • 如果上面操作完还是不行那就是路由信息配置有问题了,使用命令查看路由信息(主要是网关和DNS配置信息)
ip route

确认网关与DNS配置没有问题,如果有问题可以修改“网上信息”。如ens192网卡

vim /etc/sysconfig/network-scripts/ifcfg-ens192
  1. 监测每台服务都需要安装node_export
    docker run -d -p 9100:9100 --name node-exporter prom/node-exporter:latest
    

3.监测每台服务都需要安装redis_export

nohup ./redis_exporter -redis.addr=192.168.20.240:6379  -redis.password=3vRgLpTMLHhMSCflL1iq -web.listen-address :9121 &
