二、Prometheus监控Redis

1.下载redis_exporter

https://github.com/oliver006/redis_exporter/releases

tar -zxvf attachment\;\ filename\=redis_exporter-v1.61.0.linux-amd64.tar.gz

将其配置为系统服务：

vim /usr/lib/systemd/system/redis_exporter.service

[Unit]
Description=redis_exporter
Documentation=https://github.com/oliver006/redis_exporter
[Service]
Restart=on-failure
ExecStart=/data/prometheus/redis_exporter/redis_exporter -redis.addr 127.0.0.1:6379  -redis.password 123
[Install]
WantedBy=multi-user.target

启动redis_exporter:

systemctl start redis_exporter

查看redis_exporter状态:

systemctl status redis_exporter

修改prometheus.yml，在scrape_configs下添加

  - job_name: "redis_exporter"
    static_configs:
      - targets: ["127.0.0.1:9121"]

重新加载配置文件

curl -XPOST http://127.0.0.1:9090/-/reload
