1 系统安装docker

yum install -y docker
systemctl enable docker
systemctl start docker

2 下载镜像包：

docker pull prom/prometheus
docker pull prom/node-exporter
docker pull grafana/grafana

3启动node-exporter

3.1 启动镜像

docker run -d -p 9100:9100 -v /proc:/host/proc:ro -v /sys:/host/sys:ro -v /:/rootfs:ro --net=host prom/node-exporter

注：

1. 试过以其他端口启动，不成功。
2. 由于node-exporter是需要采集服务器的信息，所以，docker的net模式为 --net=host，意思是 docker使用的网络实际上和宿主机一样。

3.2 登陆

http://ipserver:9100/metrics

4 启动prometheus

4.1 新建目录prometheus,编辑配置文件prometheus.yml,内容如下

global:
scrape_interval: 60s
evaluation_interval: 60s

scrape_configs:
- job_name: prometheus
static_configs:
- targets: [‘localhost:9090‘]
labels:
instance: prometheus

- job_name: linux
static_configs:
- targets: [‘ipserver:9100‘] --这个是需要监控的linux服务器的地址
labels:
instance: localhost

4.2 启动prometheus

docker run -d -p 19090:9090 -v /opt/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus

4.3 登陆url

http://ipserver:19090/graph http://ipserver:19090/status

5 安装grafana

5.1 新建空文件夹/opt/grafana-storage

      mkdir /opt/grafana-storage
      chmod 777 -R /opt/grafana-storage

5.2 启动grafana

docker run -d -p 13000:3000 --name=grafana -v /opt/grafana-storage:/var/lib/grafana grafana/grafana

5.3 登陆url
    http://ipserver:13000/login

   ######错误######
  启动grafana容器出错的话，
  GF_PATHS_DATA=‘/var/lib/grafana‘ is not writable.
  You may have issues with file permissions, more information here: http://docs.grafana.org/installation/docker/#migration-from-a-previous-version-of-the-docker-container-to-5-1-or-later
  mkdir: cannot create directory ‘/var/lib/grafana/plugins‘: Permission denied

  ---------解决办法：chmod 777 -R /opt/grafana-storage
