使用prometheus监控redis集群

1.安装下载redis_exporter
下载地址：
https://github.com/oliver006/redis_exporter/releases

tar -xvf redis_exporter-v1.55.0.linux-amd64.tar.gz -C /usr/local/
cd /usr/local/
mv redis_exporter-v1.55.0.linux-amd64/ redis_exporter

2 启动
cd /usr/local/redis_exporter
nohup ./redis_exporter -redis.addr 172.20.2.18:6379 &
nohup ./redis_exporter -redis.addr 172.20.2.18:6380 &

多实例（有密码）
cd /usr/local/redis_exporter
nohup ./redis_exporter  -redis.addr 172.2.1.3:6380  -redis.password=oj+xjlARRfJqbC+A  --web.listen-address=:9120 &
nohup ./redis_exporter  -redis.addr 172.2.1.3:6381  -redis.password=oj+xjlARRfJqbC+A  --web.listen-address=:9121 &

3 配置systemctl并加入开机自启(此步骤可省略)
3.1 redis无密码版
cat > /etc/systemd/system/redis_exporter.service << "EOF"
[Unit]
Description=redis_exporter
After=local-fs.target network-online.target network.target
Wants=local-fs.target network-online.target network.target

[Service]
ExecStart=/usr/local/redis_exporter/redis_exporter -redis.addr  172.22.201.32:6380
Restart=on-failure
[Install]
WantedBy=multi-user.target
EOF

3.2 redis有密码版
cat > /etc/systemd/system/redis_exporter.service << "EOF"
[Unit]
Description=redis_exporter
After=local-fs.target network-online.target network.target
Wants=local-fs.target network-online.target network.target

[Service]
ExecStart=/usr/local/bin/redis_exporter   -redis.addr  172.22.201.32:6380   -redis.password=oj+xjlARRfJqbC+A   --web.listen-address=:9120

Restart=on-failure
[Install]
WantedBy=multi-user.target
EOF

如果有多个实例，就创建多个service文件即可

systemctl daemon-reload
systemctl enable redis_exporter
systemctl start redis_exporter
systemctl status redis_exporter

3.3配置prometheus
vim prometheus.yaml

  - job_name: 'redis_exporter_cluster'
    static_configs:
      - targets:
        - redis://172.22.1.4:6380
                - redis://172.22.1.4:6381
    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: 172.22.15.84:9121
  #监控redis
  - job_name: 'redis_exporter'
    static_configs:
      - targets:
        - 172.22.15.84:9121
