Configure and Deploy Your Own DNS Sinkhole (Completed)
Pi-hole is a powerful tool that allows you to install, configure, and deploy a DNS sinkhole within your network. By setting up Pi-hole, you can effectively block ads, enhance network speed, and delve into the realm of DNS and network administration. This versatile software functions by acting as a DNS server for your network and filters out unwanted advertisements and tracking servers. By redirecting these requests to a blackhole, Pi-hole protects your devices from annoying ads and provides a cleaner browsing experience. Additionally, Pi-hole can significantly improve your network's speed by reducing the amount of data that needs to be downloaded. With the experience gained from using Pi-hole, you will not only achieve a more streamlined and ad-free network but also develop a deeper understanding of DNS and network administration.
Proxmox VE High Availability (HA) Configuration
To ensure redundancy and disaster prevention, I will configure Proxmox VE into a High Availability (HA) setup. This involves setting up a cluster with multiple nodes, ensuring that if one node fails, the virtual machines (VMs) and containers can automatically failover to another node. Key steps include:
Cluster Setup: Create a Proxmox VE cluster with at least three nodes to maintain quorum and prevent data inconsistencies.
Fencing: Implement fencing devices to isolate failed nodes and ensure the integrity of the cluster.
HA Manager: Utilize Proxmox VE’s HA Manager to automate the detection of node failures and manage the failover process.
CEPH Monitoring Configuration
For effective monitoring of my CEPH storage cluster, I will set up a comprehensive monitoring stack. This includes:
Node Exporter: Deploy a node-exporter service on each cluster node to collect host-level metrics such as CPU and memory utilization.
Prometheus: Set up Prometheus to gather and store metrics from the node-exporters and other CEPH components.
Alertmanager: Configure Alertmanager to handle alerts and notifications based on the metrics collected.
Grafana: Deploy Grafana for visualizing the metrics and creating dashboards to monitor the health and performance of the CEPH cluster.
