docker + grafana + prometheus + Mysql

1、prometheus 部署，系统架构图

2、prometheus 部署过程

1. docker pull prom/prometheus 2. docker run -p 9090:9090 -v /prometheus-data \ prom/prometheus --config.file=/prometheus-data/prometheus.yml 3. prometheus.yml global: scrape_interval: 15s evaluation_interval: 15s scrape_configs: - job_name: linux static_configs: - targets: ['host:9100'] labels: instance: db1 - job_name: mysql static_configs: - targets: ['host:9104'] labels: instance: db1 - job_name: 'consul-knowledge' metrics_path: '/actuator/prometheus' consul_sd_configs: - server: '10.1.204.114:8500' services: ['knowledge-service']

3、部署exporter

$ wget https://github.com/prometheus/node_exporter/releases/download/v0.16.0/node_exporter-0.16.0.linux-amd64.tar.gz $ wget https://github.com/prometheus/mysqld_exporter/releases/download/v0.10.0/mysqld_exporter-0.10.0.linux-amd64.tar.gz -O mysqld_exporter-0.10.0.linux-amd64.tar.gz $ mkdir /usr/local/services/prometheus_exporters $ tar zxf node_exporter-0.14.0.linux-amd64.tar.gz -C /usr/local/services/prometheus_exporters --strip-components=1 $ tar zxf mysqld_exporter-0.10.0.linux-amd64.tar.gz -C /usr/local/services/prometheus_exporters --strip-components=1 运行node_exporter $ cd /usr/local/services/prometheus_exporters $ ./node_exporter

 

4、mysqld_exporter需要连接到Mysql，所以需要Mysql的权限，我们先为它创建用户并赋予所需的权限：

mysql> GRANT REPLICATION CLIENT, PROCESS ON *.* TO 'prom'@'localhost' identified by 'abc123'; mysql> GRANT SELECT ON performance_schema.* TO 'prom'@'localhost'; cd /usr/local/services/prometheus_exporters $ cat << EOF > .my.cnf [client] user=prom password=abc123 EOF $ ./mysqld_exporter -config.my-cnf=".my.cnf"

5、部署grafana

docker pull grafana/grafana docker run -d --name=grafana -p 3000:3000 grafana/grafana server： https://grafana.com/dashboards/8919 mysql： https://grafana.com/dashboards/6239
