3.执行 vim /opt/minitor/prometheus/prometheus.yml,添加以下配置文件(红色部分)：
scrape_configs:
# The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
- job_name: 'prometheus'
# metrics_path defaults to '/metrics'
# scheme defaults to 'http'.
static_configs:
- targets: ['ip:9090']
labels:
instance: prometheus
- job_name: redis
static_configs:
- targets: ['ip:9121']
labels:
instance: redis
4.启动 redis_exporter
nohup ./redis_exporter -redis.addr ip:端口 -redis.password "密码" &
5.去prometheus中查看redis的状态
