一、redis集群情况

#redis集群IP和端口，集群配置了密码
136.xxx.102.112:7000
136.xxx.102.112:7001
136.xxx.102.112:7002
136.xxx.102.113:7000
136.xxx.102.113:7001
136.xxx.102.113:7002

二、redis_exporter部署，配置prometheus

#将文件解压并修改文件夹名称，插件不一定安装redis端
tar -zxvf redis_exporter-v1.3.5.linux-amd64.tar.gz
mv redis_exporter-v1.3.5.linux-amd64 redis_exporter
#修改prometheus配置，注意文件格式，如果文件有问题会导致prometheus无法启动
vi prometheus.yml
  - job_name: 'redis_exporter_targets'
    static_configs:
      - targets:
        - redis://136.127.102.112:7000
        - redis://136.127.102.112:7001
        - redis://136.127.102.112:7002
        - redis://136.127.102.113:7000
        - redis://136.127.102.113:7001
        - redis://136.127.102.113:7002
    params:
      check-keys: ["metrics:*"]
    metrics_path: /scrape
    relabel_configs:
      - source_labels: [__address__]
        target_label: __param_target
      - source_labels: [__param_target]
        target_label: instance
      - target_label: __address__
        replacement: 136.127.102.112:9122
  - job_name: 'redis_exporter'
    static_configs:
      - targets:
        - 136.127.102.112:9122

三、探针启动

#启动探针，因为是集群只需要写清楚密码即可，默认监听端口为9121，由于有密码需要将端口设置为9122
nohup ./redis_exporter -redis.password passwd123 -web.listen-address 0.0.0.0:9122 &
#prometheus需要重启

四、效果
